Three Workers Killed in a Pulling Unit Explosion Near Rankin — What Their Families Need to Know Right Now
If you are reading this because someone you love did not come home from the well site that Tuesday morning in 2015, we want you to understand something before anything else: the company that owned the well and the company that employed your loved one are already, right now, building their defense. The well operator and the contractor employer are two different companies, and each one is already pointing at the other. The choices you make in the next few days — what you sign, what you say, who you talk to — will shape everything that follows. We are writing this page so that when that phone rings, you already know what is true and what is a trap.
Three men died on a pulling unit crew at a Parsley Energy well site near Rankin, in Upton County, Texas. A fourth worker on the site survived. The Upton County Sheriff’s Office responded. OSHA launched a federal fatality investigation. The well was owned by Parsley Energy of Midland. The men who died were employed by Mason Well Service Ltd. of Odessa, an independent contractor. That last sentence — two company names, one word “independent contractor” — is the single most important fact in this case, and it is the fact the companies are counting on you not understanding.
We handle wrongful death claims and workplace accident cases across Texas, including the Permian Basin, and we built this page to give you what no adjuster and no company representative will: the truth about your rights, the clock that is already running on the evidence, and the fight that is coming. This is legal information, not legal advice — but it is the information we wish every family had before the insurance company’s first call.
What Happened Near Rankin: The Incident
Rankin is the county seat of Upton County, Texas — a town of fewer than 4,000 people sitting about 40 miles south of Midland in the heart of the Permian Basin. The Permian Basin is the most prolific oil and gas production region in the United States, and Upton County sits squarely in its center. The land around Rankin is oilfield country: pump jacks, well pads, service roads, and the constant movement of crews and equipment that keep the basin producing.
On a Tuesday morning in 2015, a pulling unit crew from Mason Well Service was at a Parsley Energy well site near Rankin performing well-servicing work. An explosion occurred. Three members of that crew were killed. One worker at the site was not injured.
The Occupational Safety and Health Administration website describes a pulling unit as a well-servicing outfit.
The Upton County Sheriff’s Office responded to the scene. OSHA, the federal workplace safety agency, launched a fatality investigation — a process that typically takes six to nine months to complete and produces a file that becomes the backbone of any wrongful death case. The Texas Railroad Commission, which regulates oil and gas well operations statewide, maintains records on well permits, operators, and incident reports that are discoverable in litigation.
No cause of the explosion was reported in the initial coverage. The names of the deceased were not released at the time. What was reported — and what matters most — is the corporate structure on that well site.
The Two Companies on That Well Site — and Why This Split Decides Your Case
The well is owned by Parsley Energy of Midland. Company spokeswoman Lisa Elliott says the workers who died were employed by Mason Well Service Ltd. of Odessa, an independent contractor.
Read that sentence again. It is the sentence the insurance companies hope you skim past. Here is what it means in plain English:
Parsley Energy was the well owner and operator. Parsley owned the well, owned the site, controlled the property, and hired Mason Well Service to perform well-servicing work. As the premises owner and operator, Parsley owed a duty to every worker on that site to maintain the premises in a reasonably safe condition — including ensuring that wellbore conditions were safe for workover operations and that the contractors it hired were competent and properly vetted.
Mason Well Service Ltd. was the employer of the three men who died. Mason was an independent contractor engaged by Parsley to perform pulling unit operations. As the employer, Mason’s legal obligations to its workers — and the legal remedies available to the families — depend on a single threshold question that most families never think to ask: did Mason Well Service carry workers’ compensation insurance?
This is the fork in the road. In Texas, the answer to that one question transforms the case:
-
If Mason was a non-subscriber (did not carry workers’ comp), the families can sue Mason directly for ordinary negligence — and Mason is barred from asserting contributory negligence as a defense. This is one of the most powerful liability tracks in American tort law, unique to Texas.
-
If Mason was a subscriber (carried workers’ comp), the exclusive remedy provision generally bars negligence claims against the employer — but the families can pursue a gross negligence claim that pierces that bar, requiring proof of conscious indifference to the workers’ safety.
-
Either way, the families can pursue third-party claims against Parsley Energy for premises liability and negligent selection and supervision of the independent contractor — and Parsley cannot hide behind Mason’s workers’ comp coverage.
The companies are counting on you to accept the first check that arrives and sign the first paper put in front of you. That paper is designed to release both companies from liability before you ever learn which fork you were standing at. We will come back to this. First, you need to understand what a pulling unit does — and why it can explode.
What a Pulling Unit Does — and Why It Explodes
A pulling unit is a piece of well-servicing equipment used to perform workover operations on existing oil and gas wells. The crew’s job is to pull tubing, rods, and other equipment out of the wellbore — sometimes to repair the well, sometimes to replace downhole equipment, sometimes to prepare the well for a new completion. The pulling unit itself is a truck-mounted rig with a hoist, a mast or derrick, and a power system that drives the pulling operation.
Here is what makes this work dangerous, and here is where the physics of an explosion live:
Trapped wellbore pressure. When a crew pulls tubing out of a well, they are opening a system that may contain pressure from trapped hydrocarbons — oil, natural gas, or both. If the well was not properly killed (filled with fluid to suppress formation pressure) before the work began, or if the pressure-control equipment was inadequate or improperly operated, that pressure can be released suddenly. Gas expands rapidly when it escapes confinement. A cloud of combustible gas forms at the wellhead.
Ignition sources. A pulling unit operates with diesel engines, electrical systems, motors, and mechanical equipment — any of which can generate a spark. The well site itself may have heaters, generators, or other ignition sources nearby. When a gas cloud meets an ignition source, the result is a flash fire or a vapor-cloud explosion. The speed of ignition is measured in fractions of a second. The force of the blast depends on the volume of gas, the confinement of the space, and the proximity of the crew to the wellhead.
Hydrogen sulfide (H2S). Permian Basin wells routinely produce hydrogen sulfide — a gas that is lethal at low concentrations and can kill a worker in seconds at higher concentrations. H2S is also flammable. A well that releases H2S during a pulling operation creates both a toxic exposure hazard and an explosion hazard simultaneously.
Pressure-control equipment. The equipment designed to contain wellbore pressure during servicing — blowout preventers, lubricators, stuffing boxes, and related components — must be properly sized, installed, tested, and maintained. If any of this equipment fails, or if it was never properly deployed, the crew is standing directly in the path of whatever the well releases.
The explosion that killed three men near Rankin came from one or more of these mechanisms. Which one — and who is responsible for it — is what the investigation must establish. The answer lives in the equipment, the well file, the training records, and the surviving worker’s account. All of that evidence is perishable. Some of it is already gone.
Texas Oilfield Wrongful Death Law: The Three Tracks
When a worker is killed on an oilfield site in Texas, the families may have multiple legal tracks to pursue. Here is the map — and we are going to walk each one because the companies will not explain this to you.
Track 1: The Third-Party Claim Against Parsley Energy (Premises Liability)
Parsley Energy owned and operated the well site. Under Texas premises liability law, a property owner owes a duty to workers invited onto the property to maintain the premises in a reasonably safe condition. For an oil and gas well operator, this duty extends beyond simply keeping the ground clear — it includes ensuring that wellbore conditions are safe for the workover operations being performed, that the well’s pressure profile and gas content are known and communicated to the contractor, and that the contractor selected to perform the work is competent and properly equipped.
Texas law also permits claims against premises owners for negligent selection and supervision of an independent contractor. If Parsley Energy failed to investigate Mason Well Service’s safety record, training protocols, and equipment maintenance practices before engaging it for inherently dangerous well-servicing work, Parsley can be held liable — even though Mason was the direct employer. Texas law recognizes that a premises owner who retains control over the instrumentality or the manner of the contractor’s work bears its own duty of care.
This is the track that reaches the deepest pockets. Parsley Energy, as a publicly traded Permian Basin exploration and production company, carried a liability insurance tower and corporate assets far beyond what a small well-service contractor in Odessa could match. The third-party claim against Parsley is not barred by workers’ compensation exclusivity — it runs alongside whatever claim exists against Mason, not through it.
Track 2: The Non-Subscriber Claim Against Mason Well Service (If No Workers’ Comp)
Texas is the only state in the country that allows most private employers to opt out of workers’ compensation entirely. If Mason Well Service did not carry workers’ comp insurance — if it was a non-subscriber — then the families of the three killed workers can sue Mason directly for ordinary negligence. And here is the part that makes this doctrine so powerful: a non-subscribing employer cannot assert contributory negligence as a defense. If the defense tries to argue that the workers were partly at fault for the explosion, that argument is simply not available to a non-subscribing employer. The jury never hears it.
This means that in a non-subscriber case, the families only need to prove that Mason’s negligence caused the explosion — they do not need to defend their loved ones’ conduct at the site. The standard of proof is ordinary negligence: did Mason fail to train the crew properly, fail to supervise the operation, fail to maintain the equipment, or fail to enforce safe pulling-unit procedures? If yes, and if that failure caused the deaths, Mason is liable — and it cannot reduce the recovery by pointing to the workers’ own actions.
Determining whether Mason Well Service was a subscriber or a non-subscriber is the first discovery battle in this case. It is a threshold strategic question that transforms the case value. We cannot state what Mason’s status was — that is a fact to be confirmed through investigation. But we can tell you that the answer is discoverable, that it matters more than almost any other single fact in the case, and that the families’ attorneys should move to establish it immediately.
Track 3: The Gross Negligence Claim Against Mason Well Service (If Workers’ Comp Subscriber)
If Mason Well Service did carry workers’ compensation insurance, the exclusive remedy provision of the Texas Workers’ Compensation Act generally bars negligence claims against the employer. The families would receive whatever death benefits the workers’ comp policy provides — which are capped by statute and typically far below what a wrongful death verdict would produce.
But Texas law creates an exception: a gross negligence claim can pierce the exclusive remedy bar. Gross negligence, under Texas law, requires proof of conscious indifference to the safety of the workers — meaning Mason actually knew of the danger and deliberately disregarded it, or the danger was so obvious that Mason must have known. A pulling unit explosion may support this if the evidence shows that safety procedures were knowingly disregarded, that prior incidents were ignored, or that equipment known to be failing was kept in service.
If gross negligence is proven, the families can recover from Mason beyond the workers’ comp benefits — and punitive damages become available. OSHA findings of willful violations can be powerful evidence in support of a gross negligence showing.
The Statute of Limitations
Texas wrongful death and survival actions are governed by a two-year statute of limitations — generally running from the date of death. This is the Texas wrongful-death statute of limitations, and missing it bars the claim forever. Two years sounds like a long time when you are grieving, but the evidence in an oilfield explosion case can be gone in days, the OSHA investigation takes six to nine months, and building the expert case takes months beyond that. The two-year deadline is real, but the evidence deadline is far shorter.
The Workers’ Compensation Fork: Why This Is the First Question
We have workers’ compensation experience on both sides of the table, and we can tell you that in Texas oilfield death cases, no single fact reshapes the case more than the employer’s subscription status. Here is why:
If Mason Well Service was a subscriber, the workers’ comp death benefits are the exclusive remedy against Mason for ordinary negligence. Those benefits are capped — they include a burial allowance and weekly income benefits to the surviving dependents, calculated as a percentage of the deceased worker’s average weekly wage, subject to statutory maximums. For a well-servicing worker earning $60,000 to $120,000 or more with overtime in the Permian Basin, the comp benefits are a fraction of what the family actually lost. The gross negligence exception is the only path to additional recovery from Mason itself — and gross negligence is a high bar.
If Mason was a non-subscriber, the entire landscape changes. The families sue Mason in tort for the full measure of damages — lost earning capacity, lost household services, mental anguish, loss of companionship, and (if gross negligence is shown) punitive damages. Mason cannot raise contributory negligence. The case value can be dramatically higher because the recovery is not capped by the workers’ comp benefit schedule.
This is why the first letter we send in a case like this demands confirmation of the employer’s workers’ compensation status. The answer is not something the company volunteers — but it is something the law requires them to produce in discovery. And the answer changes everything.
Premises Liability: What the Well Operator Owes the Workers on Its Property
Parsley Energy, as the well owner and operator, had duties that extended beyond simply hiring a contractor and stepping back. Here is what Texas law requires of a well operator in this position:
Safe wellbore conditions. The operator knows — or is in the best position to know — the pressure profile, gas content, production history, and prior incidents associated with its own well. Before a pulling unit crew begins workover operations, the operator has a duty to ensure that the well is safe for those operations. If the well had a history of pressure problems, if it had produced hydrogen sulfide, if it had experienced prior blowouts or pressure events, that information must be communicated to the contractor. A well operator that sends a contractor’s crew onto a well with known pressure hazards and says nothing has breached its duty.
Proper contractor selection. Texas law permits claims against premises owners for negligent selection of an independent contractor. Did Parsley investigate Mason Well Service’s safety record before hiring them? Did Parsley review Mason’s training protocols, equipment maintenance practices, and prior incident history? Did Parsley verify that Mason’s crews were properly trained and certified for the specific pulling unit operations being performed? If the answer to any of these is no, Parsley’s own negligence — separate from Mason’s — contributed to the deaths.
Site conditions and supervision. The well site itself — the layout, the location of ignition sources relative to the wellhead, the availability of emergency equipment, the condition of access roads for emergency response — is under the operator’s control. If site conditions contributed to the explosion or to the severity of its consequences, the operator bears responsibility.
The API RP 54 standard. The American Petroleum Institute’s Recommended Practice 54 establishes industry-recognized safety practices for oil and gas well drilling and servicing operations, including pulling unit and workover operations. While API standards are not statutes, they are widely recognized in the industry as the standard of care. Violation of API RP 54 can serve as evidence of negligence — evidence that the defendant fell below the recognized industry standard for safe well-servicing operations.
OSHA’s Fatality Investigation: What It Does and When It Matters
OSHA has jurisdiction over workplace safety at oil and gas well sites and launched a fatality investigation under its standard procedures. Here is what that investigation produces and why it matters to the families:
The OSHA investigation file typically includes witness statements (including the surviving worker’s account), photographs of the scene and equipment, measurements and physical evidence documentation, examination of the pulling unit and wellhead equipment, review of training and personnel records, and a root-cause analysis of the explosion. The file is typically completed within six to nine months of the incident.
OSHA citations. If the investigation reveals safety violations, OSHA will issue citations — which may be classified as serious, willful, or repeated. A willful citation is the most powerful for a wrongful death case: it means OSHA found that the employer knowingly violated a safety standard or acted with plain indifference to employee safety. Willful citations can support both liability proof and the gross negligence showing needed for punitive damages. OSHA’s civil penalties — as of the 2025/2026 adjustment — can reach up to $165,514 per willful or repeated violation, but the penalty amount itself is not the family’s remedy. The citation is the evidence.
The limitation. An OSHA citation is an agency finding, not a court judgment of civil liability. Citations can be contested before the Occupational Safety and Review Commission and may be modified or vacated. We never present an OSHA citation as a court’s finding of fault — we present it as documented evidence of a safety failure that the defendant must explain.
The clock. The OSHA investigation takes six to nine months. During that time, the physical evidence at the well site is changing — equipment is being repaired or removed, the site is being remediated, and the scene is being altered. The families cannot wait for OSHA’s findings before preserving evidence. The preservation work has to happen in the first days, not after OSHA finishes.
Evidence Preservation: The Clock Is Already Running
This is the section we need you to read most carefully, because the evidence in an oilfield explosion case dies faster than in almost any other type of case we handle. Well sites are working operations. They are not crime scenes that get taped off and preserved for months. Within days to weeks of a fatal incident, the well site is typically remediated and returned to operation. Equipment is repaired, scrapped, or removed. The scene is altered. The physical proof of what caused the explosion can disappear before the funeral is over.
Here is what exists, who holds it, and how fast it can legally disappear:
The pulling unit and wellhead equipment. The physical condition of the pulling unit, the wellhead, the pressure-control devices, and any ignition-source equipment is the single most critical evidence in establishing whether equipment failure, improper operation, or inadequate maintenance caused the explosion. This equipment is held by Mason Well Service (the pulling unit) and Parsley Energy (the wellhead and well site). It can be repaired, scrapped, or removed from the site within days to weeks unless a spoliation letter and, if necessary, a temporary restraining order are issued immediately. Urgency: highest.
The well site scene and debris field. Burn patterns, blast directionality, equipment fragmentation patterns, and the spatial relationship between the pulling unit and the wellhead establish the explosion’s origin and propagation. The scene is altered within hours. The Upton County Sheriff’s Office may have taken photographs, and the companies may have their own photographs — but those photographs are not guaranteed to be preserved without a formal demand. Urgency: critical.
Mason Well Service training and personnel records. These records establish whether the deceased crew members were properly trained, certified, and supervised for pulling unit operations. Personnel records, training logs, and safety meeting documentation can be discarded or altered. A preservation letter to Mason Well Service is essential. Urgency: high.
Parsley Energy well file. The well file includes well history, pressure data, prior incident records, known gas content, and any previous blowout or pressure incidents at this well. These records establish foreseeability and Parsley’s duty to warn and prepare contractors. Well files are maintained but can be modified as operations continue. A litigation hold letter to Parsley Energy is urgent. Urgency: high.
The surviving worker’s statement. The uninjured worker is the sole percipient witness to the explosion sequence. Their contemporaneous observations, any photographs they took, and their communications before and after the incident are irreplaceable. The surviving worker may be a Mason employee subject to pressure to cooperate with the company’s narrative. Independent contact through counsel should be attempted. Urgency: immediate.
Texas Railroad Commission well records. The RRC maintains well permits, completion reports, production data, and any incident reports. These are public and generally preserved, but operator-submitted incident reports should be requested promptly. Urgency: moderate.
Autopsy and toxicology reports. The medical examiner’s office will produce cause and manner of death, burn patterns, blast-force injuries, and toxicology. These confirm the mechanism of death and support the survival claim for pre-death pain and suffering. Ensure all tissue and toxicology samples are preserved. Urgency: moderate.
The spoliation letter. The preservation letter — sent to both Parsley Energy and Mason Well Service within 48 hours of being retained — is the single most important early action in an oilfield explosion case. It demands that the companies freeze all physical evidence, documents, electronic data, and records related to the incident. If either party is unresponsive, an emergency temporary restraining order for equipment preservation may be necessary. The day you call a lawyer is the day that letter goes out.
The Insurance Adjuster Playbook: What the Companies Are Already Doing
Lupe Peña spent years inside a national insurance-defense firm before coming to our side of the table. He sat in the rooms where adjusters and their software decided how to deny, delay, and devalue claims. He knows the plays because he used to run them. Here is what the companies are already doing — and here is the counter to each play:
Play 1: The “just checking in” recorded statement call. Within days of the incident, someone friendly will call the family. They will say they are “just checking on you” or “need to gather some information for our records.” They will ask you to “just tell us what happened” — on a recording built to be quoted against you later. The counter: do not give a recorded statement to any insurance representative, company investigator, or claims adjuster before consulting counsel. You are not required to. The call is not designed to help you. It is designed to lock you into a narrative before you know what happened.
Play 2: The fast settlement check with a release buried under it. A check may arrive quickly — sometimes before the funeral. It will come with paperwork that, in the fine print, releases the company from all liability related to the death. Once you sign that release, the case is over. There is no undoing it. The counter: do not sign any document, release, or settlement agreement from Parsley Energy, Mason Well Service, or any insurance representative before consulting counsel. These documents are designed to limit the company’s liability, not to help the families.
Play 3: “Your loved one assumed the risk.” The defense will argue that oilfield work is inherently dangerous and that the workers knew and accepted the risks. The counter: under Texas law, if Mason was a non-subscriber, contributory negligence and assumption of risk are not available defenses. If Mason was a subscriber, the gross negligence exception still applies. And against Parsley Energy as a third party, the workers’ acceptance of the job does not absolve the operator of its duty to maintain safe premises and select competent contractors. The workers did not assume the risk of an explosion caused by someone else’s negligence.
Play 4: The finger-pointing defense. Parsley will blame Mason. Mason will blame Parsley. Each company will argue that the other was responsible for the safety failure. The counter: pursue all responsible parties simultaneously. The families’ recovery should not depend on which company the jury finds more culpable — it should come from whichever company was negligent, and in Texas, the comparative fault system allows the jury to allocate fault among all defendants.
Play 5: The “we need more time” delay. The companies may string out the process, offering partial information, requesting extensions, and running the clock toward the two-year statute of limitations. The counter: a firm that moves fast — sending preservation letters, filing suit, conducting discovery — forces the companies to produce evidence and answer questions on a court-imposed schedule, not their own.
What a Case Like This Is Worth
We are not going to give you a number and call it a promise. Every case is different, and the value of a wrongful death claim depends on the specific facts — the age and earning capacity of each decedent, their marital and parental status, the allocation of fault among defendants, and whether punitive damages are available.
But we can give you the framework that a forensic economist and life-care planner would use to build the number, and we can give you the range that cases of this type can reach based on the variables.
Economic damages. Permian Basin well-servicing workers routinely earn $60,000 to $120,000 or more annually, with significant overtime. Lost earning capacity is projected across the worker’s expected worklife — not just to retirement age, but using worklife expectancy tables that account for labor-force participation patterns. Fringe benefits — health insurance, retirement contributions, paid leave — add approximately 30% on top of wages, per federal labor data. Lost household services — the value of the unpaid work the decedent performed at home, from childcare to repairs to household management — is recoverable and valued using federal time-use data and market replacement wages. Funeral and burial expenses are recoverable. Medical expenses for any pre-death treatment are recoverable through the survival claim.
Non-economic damages. The mental anguish and emotional distress of surviving family members is recoverable under the Texas Wrongful Death Act. Loss of companionship, society, and counsel — the loss of the relationship itself — is recoverable. The decedents’ pre-death pain and suffering is recoverable through the survival claim, and the duration of pre-death consciousness (established by the autopsy and the surviving worker’s account) directly informs this element.
Punitive damages. Available upon a showing of gross negligence — a realistic claim if OSHA findings reveal willful safety violations, ignored prior incidents, or conscious indifference to known wellbore pressure hazards. Punitive damages in Texas are subject to statutory caps, but the caps operate on top of the full economic and non-economic damages, not as a substitute for them.
The case value range. Based on the variables in this case — three fatalities in an inherently dangerous workover operation, a well operator with deep corporate pockets, the workers’ comp subscription status of the employer, and the potential for OSHA willful citations supporting gross negligence — the aggregate value across all three families could range from approximately $12,000,000 on the low end to $50,000,000 or more on the high end. The low end assumes a subscribing employer (limiting direct claims against Mason), strong comparative fault defenses, third-party claims against Parsley settled at moderate policy limits, and no punitive finding. The high end assumes non-subscriber status for Mason, clear Parsley Energy premises liability with negligent contractor selection findings, OSHA willful citations supporting gross negligence, and punitive damages within Texas statutory caps.
Individual family recoveries will vary by decedent age, dependents, and earning capacity. Each death independently supports a multi-million-dollar claim. Past results depend on the facts of each case and do not guarantee future outcomes.
The Surviving Worker: The Most Important Witness in This Case
One worker at the site was not injured. That person is the sole percipient witness to the explosion sequence — what the crew was doing in the moments before the blast, whether there were warning signs, whether proper procedures were being followed, what the equipment was doing, and the timeline of events from the beginning of the shift to the moment of the explosion.
This surviving worker’s account may establish:
-
The explosion mechanism. What happened in the seconds before the blast — a pressure release, a gas cloud, a spark, a sequence of events that points to a specific cause.
-
Procedural deviations. Whether the crew was following proper pulling unit procedures or whether shortcuts were being taken — and if so, who directed them.
-
Equipment condition. Whether the pulling unit, wellhead, and pressure-control equipment were functioning properly before the explosion or whether there were signs of malfunction.
-
Pre-incident warnings. Whether there were any warnings — pressure readings, gas alarms, equipment noises — that were seen, heard, or ignored before the blast.
-
Survival claim duration. Whether the deceased workers survived briefly after the explosion — even seconds or minutes of consciousness can support a survival claim for pre-death pain and suffering.
The surviving worker may be a Mason Well Service employee, subject to pressure to cooperate with the company’s narrative. They may have been told what to say or what not to say. They may be afraid for their own job. Independent contact with this witness — through counsel, not through the company — should be attempted as early as possible, before the account is shaped by the company’s interests.
The First 72 Hours: What to Do and What to Refuse
If you are in the first hours or days after losing someone in this explosion, here is what we need you to know:
DO:
-
Get the names and contact information of anyone who was at the site or who has information about the incident. Do not interview them yourself — just preserve how to reach them.
-
Photograph anything you have access to — if a family member was given personal effects from the site, photograph them before returning anything.
-
Request a copy of the autopsy report from the medical examiner’s office when it is available. Ensure the medical examiner preserves all tissue and toxicology samples.
-
Contact an attorney who handles Texas oilfield wrongful death cases. The preservation letter needs to go out immediately — to both Parsley Energy and Mason Well Service — targeting the pulling unit, wellhead equipment, training records, and well file.
-
Obtain the deceased worker’s employment records, pay stubs, W-2s, and benefit statements. These document the earning capacity that was lost.
-
Talk to the other families. There are three families who lost someone in this explosion. The cases may be coordinated, and the evidence preservation effort is stronger when it comes from multiple families simultaneously.
DO NOT:
-
Do not sign any document, release, or settlement agreement from Parsley Energy, Mason Well Service, or any insurance representative. Not now, not until you have spoken with a lawyer. These documents are designed to end the case before it begins.
-
Do not give a recorded statement to any insurance company, company investigator, or claims adjuster. You are not legally required to do so, and anything you say will be transcribed and used to limit the company’s liability.
-
Do not post about the incident on social media. Insurance investigators monitor social media, and even a seemingly innocent post can be taken out of context and used against the family.
-
Do not accept the first settlement offer. The first offer is always a fraction of what the case is worth. It is designed to close the file cheaply before the family understands the full extent of their losses.
-
Do not assume the workers’ compensation system is your only option. In Texas, the non-subscriber doctrine and the third-party claim against the well operator may provide far greater recovery than the comp system alone.
-
Do not wait. The two-year statute of limitations is real, but the evidence clock is far shorter. The physical evidence at the well site can be gone in days. The pulling unit can be repaired or scrapped. The scene can be altered. The surviving worker’s memory is freshest now, not in six months.
How We Build an Oilfield Wrongful Death Case
Here is how a case like this is actually built — the chronological walk from the first call to resolution:
Week one. The preservation letter goes out to Parsley Energy and Mason Well Service within 48 hours, targeting the pulling unit, wellhead equipment, pressure-control devices, training records, personnel files, and the well file. If either party is unresponsive, we seek an emergency temporary restraining order for equipment preservation. We engage a petroleum engineering expert specializing in well-servicing operations and a fire and explosion origin-and-cause investigator to conduct an independent site inspection before evidence is altered. We begin identifying and preserving the surviving worker’s account.
Months one through three. We confirm Mason Well Service’s workers’ compensation subscription status — the threshold question that transforms the case. We file the wrongful death and survival actions on behalf of the families. We serve discovery demands on both Parsley and Mason, targeting the well file, the training records, the equipment maintenance history, the prior incident records, and the internal communications related to the explosion.
Months three through six. The depositions begin. The Mason Well Service safety director explains under oath how the crew was trained and supervised. The Parsley Energy field manager explains under oath what they knew about the well’s pressure profile and gas content before the crew was sent in. Equipment manufacturers are identified and joined if the pulling unit or pressure-control equipment contained a design or manufacturing defect.
Months six through nine. OSHA releases its fatality investigation file. Any willful or serious citations become powerful leverage — both for liability proof and for the gross negligence showing needed to pursue punitive damages. Our petroleum engineering expert and fire investigator complete their independent reconstructions, tying the physical evidence to the procedural failures.
Months nine through eighteen. The expert reports are exchanged. The life-care planner and forensic economist build the damages model — lost earning capacity, lost household services, lost fringe benefits, reduced to present value. Mediation may be scheduled, but only after OSHA findings and expert reconstructions are complete, so that any settlement demand is built on the full evidentiary record, not on speculation.
Resolution. Most oilfield wrongful death cases resolve through settlement — but the settlement value is built on the strength of the evidence and the credibility of the trial threat. If the companies will not offer what the case is worth, we try the case. In Upton County, the jury will be twelve people from the community — and in a county of fewer than 4,000 residents in the heart of the Permian Basin, those jurors will understand the oilfield. They will know what a pulling unit is. They will know what a well site looks like. The question is whether they also understand that the companies had a duty to keep those workers safe — and that is what the trial is about.
Frequently Asked Questions
Can we sue if the employer had workers’ compensation?
Yes — but the path depends on the employer’s status. If Mason Well Service was a workers’ comp subscriber, the exclusive remedy provision generally bars ordinary negligence claims against the employer. However, the families can pursue a gross negligence claim that pierces that bar, and they can pursue third-party claims against Parsley Energy as the well owner and operator. If Mason was a non-subscriber, the families can sue Mason directly for ordinary negligence — and Mason cannot raise contributory negligence as a defense. The employer’s subscription status is the first question that must be answered.
How long do we have to file a wrongful death claim in Texas?
Texas wrongful death and survival actions are generally subject to a two-year statute of limitations running from the date of death. This is a hard deadline — missing it bars the claim forever. But the evidence in an oilfield explosion case dies far faster than the two-year clock. The physical equipment at the well site can be gone in days. The preservation letter needs to go out immediately, not after the family has had time to grieve. Two years is the legal deadline; the practical evidence deadline is measured in days and weeks.
Who is responsible — the well operator or the contractor employer?
Both may be. Parsley Energy, as the well owner and operator, owes a duty to maintain safe premises and to select and supervise competent contractors. Mason Well Service, as the employer, owes a duty to train, supervise, and equip its crew for safe pulling unit operations. In Texas, the comparative fault system allows the jury to allocate fault among all responsible parties — the families do not have to choose one defendant. The companies will point at each other; the families’ recovery should come from whichever company was negligent, in proportion to that company’s share of fault.
What if the workers were partly at fault?
If Mason Well Service was a non-subscriber to workers’ compensation, contributory negligence is not a defense — the jury never hears it. If Mason was a subscriber, the gross negligence exception still applies. Against Parsley Energy as a third party, Texas follows a modified comparative fault rule with a 51% bar — meaning the family’s recovery is reduced by the decedent’s percentage of fault, but is only barred entirely if the decedent is found to be more than 50% at fault. In practice, the defense will try to pin fault on the workers, but in a pulling unit explosion, the question is usually whether the company provided proper training, equipment, and supervision — not whether the worker was careless.
What is the case worth?
The value of each family’s claim depends on the decedent’s age, earning capacity, marital and parental status, and the allocation of fault among defendants. Permian Basin well-servicing workers routinely earn $60,000 to $120,000 or more annually. Lost earning capacity, lost household services, lost fringe benefits, mental anguish, loss of companionship, and (if gross negligence is shown) punitive damages all factor into the calculation. Based on the variables in this case, the aggregate value across all three families could range from approximately $12,000,000 to $50,000,000 or more. Past results depend on the facts of each case and do not guarantee future outcomes.
What should we do about the insurance company that has already called?
Do not give a recorded statement. Do not sign any document. Do not accept any settlement check. The insurance company’s first goal is to limit the company’s liability — not to help your family. The call you received was not a courtesy. It was the first move in a process designed to close your claim for the smallest amount possible, as quickly as possible. Call a lawyer before you return the call.
What is a spoliation letter and why does it matter?
A spoliation letter — also called a preservation letter or litigation hold letter — is a formal written demand sent to Parsley Energy and Mason Well Service ordering them to preserve all physical evidence, documents, electronic data, and records related to the incident. In an oilfield explosion case, this includes the pulling unit, the wellhead equipment, the pressure-control devices, the training records, the well file, and the scene itself. Without this letter, the companies are free to repair, scrap, remove, or alter the evidence as part of their normal operations. With this letter, if evidence is destroyed, the court can impose sanctions — including an adverse inference instruction telling the jury they may assume the destroyed evidence would have been unfavorable to the company. The letter should go out within 48 hours of retaining counsel.
How long does the OSHA investigation take?
OSHA fatality investigations typically take six to nine months to complete. The investigation file will include witness statements, photographs, equipment examinations, and a root-cause analysis. If OSHA issues citations — particularly willful citations — those become powerful evidence in the wrongful death case. The families should not wait for OSHA’s findings before pursuing their claims, because the physical evidence may be gone by the time the report is finished. But the OSHA file, when it arrives, becomes the backbone of the liability proof.
Can the three families work together on this?
Yes. The three families who lost loved ones in this explosion share common defendants, common evidence, and common legal questions — particularly the workers’ compensation status of Mason Well Service and the premises liability of Parsley Energy. While each family’s damages are separate (based on each decedent’s age, earnings, and dependents), coordinating the evidence preservation effort, the discovery, and the expert work across the three families is stronger and more efficient than each family acting alone. The preservation letter is more powerful when it comes from multiple families. The spoliation threat is more credible when multiple parties are watching.
What makes Attorney911 different from other firms?
Ralph Manginello has been licensed in Texas for 27+ years and is admitted to federal court, including the U.S. District Court for the Southern District of Texas. He was a journalist before he was a lawyer — he knows how to find the story the evidence tells. Lupe Peña spent years inside a national insurance-defense firm, where he learned how adjusters value claims, how IME doctors are selected, and how delay tactics work — and now he uses that knowledge for injured clients and grieving families. He conducts full consultations in Spanish without an interpreter. We work on contingency: 33.33% before trial, 40% if the case goes to trial. We do not get paid unless we win. And we have a 48-hour evidence-preservation protocol — the preservation letter goes out the day you call, not the day we get around to it.

Lupe Peña is a former insurance-defense attorney. He spent years at a national defense firm — the rooms where claims like yours are priced, where adjusters and their software decide how to deny, delay, and devalue. He knows how Colossus values claims, how reserves are set in the first 48 hours, how IME doctors are selected, and how surveillance and social-media monitoring are deployed. He now uses that knowledge for injured clients and grieving families. He is fluent in Spanish and conducts full client consultations in Spanish without an interpreter.
We handle Texas oilfield cases and refinery and industrial accident cases — including explosions, fires, and fatal incidents in the Permian Basin.
