Completion work is high-pressure intervention on a live well.
After a well is drilled, completion and intervention operations make it produce and keep it producing — fracturing, wireline, coiled tubing, and workover. They run at the highest pressures offshore, by a stack of service contractors, on a live well.
Making the well produce.
Completion and well-intervention operations stimulate, equip, and maintain a well so it produces — through hydraulic fracturing, wireline, coiled tubing, and workover, each a specialized high-pressure operation run by service companies.
Where it goes wrong.
Extreme-pressure iron and line failures, projectiles and snapback, crush injuries at injectors and winches, chemical and explosives hazards, and well-control loss on a live well. The pressures and the contractor stack make these among the most dangerous operations offshore.
Which law — and who answers.
Completion is contractor-heavy work that crosses vessel and platform, so liability and the governing law both turn on the details.
The operator owns the completion program and the company representative who directs the work; its decisions and retained control carry liability.
The frac, wireline, coiled-tubing, and workover companies that bring the equipment and crew answer for negligent work; the borrowed-employee doctrine sorts out who controlled the job.
A defective pump, pressure-control stack, wireline tool, or length of coiled tubing supports a products claim, and unfit gear can render a vessel unseaworthy.
On a vessel the crew are usually seamen (Jones Act); on a fixed platform the LHWCA/OCSLA and §905(b) vessel negligence apply. The firm preserves whichever route fits (Jones Act vs. workers’ comp).

Each intervention has its own page below. The service-company structure is sorted through the borrowed-employee doctrine, and the crews’ status through the crew analysis.
What the other side will argue — and how it’s met.
Completion cases turn on status, the service-company web, and pressure equipment.
Completion crews work from drillships, intervention vessels, and rigs (usually seamen, Chandris) and from fixed platforms (LHWCA/OCSLA). The firm fixes the structure and preserves both the Jones Act and the §905(b) vessel negligence/OCSLA routes (Jones Act vs. workers’ comp).
The Jones Act uses pure comparative negligence; a worker’s own fault reduces a recovery but never bars it. A jury once found the injured worker zero percent at fault.
Completion runs on a stack of service contractors under the operator’s company representative. The borrowed-employee doctrine and the contracts decide who controlled the work — and the operator’s retained control and an equipment owner’s negligence both stay in the case.
Frac iron, pressure-control equipment, wireline tools, and coiled tubing are rated, inspected, and pressure-tested. A failure under pressure means inspection or testing lapsed — and the records and a pressure expert show it.
Completion cases are won on pressure records.
Whatever the intervention, the firm reconstructs the operation, sets custom and practice through a pressure and marine-safety expert, and proves what the companies knew through the job tickets, the pressure and pump data, and the iron and tool inspection logs. The crews are usually seamen, so the Jones Act reaches the employer and the unseaworthy doctrine reaches the rig.
A completion injury is rarely bad luck — it is a pressure limit exceeded, an inspection skipped, or a barrier that gave way.
What to protect while it still exists.
Completion records are detailed and routinely overwritten. Securing them early is decisive.
The job tickets, the pressure and pump records, the iron and tool inspection logs, the completion program, and the service contracts are the case — and they sit with the operator and the service companies. Demand preservation at once.
Make sure a written incident report is created, and on a vessel that a Coast Guard marine-casualty report (Form CG‑2692) is filed for a serious injury.
See a doctor promptly and describe exactly how the injury happened to every provider. An honest, contemporaneous record is the backbone of the case.

What happens when you text us
Tell us what happened — in your own words, as much or as little as you want.
We review it free. You learn whether maritime law protects you and what your options actually are.
You decide. Nothing is filed, and no one contacts your employer, unless you choose to move forward.
Your conversation with us is confidential. There is no fee unless we win. Hablamos español.
Reach out even if…
- You think the accident was partly your fault — under the Jones Act, your own fault reduces a recovery but does not bar it.
- You already gave a statement or signed something — a release signed under pressure can be challenged.
- You still work for the company — talking to a lawyer is confidential, and retaliation for pursuing a claim can itself be actionable.
- You’re not sure your case is “big enough” — that’s exactly what a free review is for.
Catastrophic offshore injury? The investigation can’t wait.
Equipment gets repaired, records get revised, and witnesses rotate off the rig. Doyle Dennis Avery LLP moves quickly to preserve the evidence and identify every responsible party. A case review costs nothing, there is no obligation, and your employer will not know you contacted us.
