Which Companies on Location May Be Responsible for Your Injury?
Many families reasonably wonder why a lawsuit might name a company the worker never worked for. The answer is the way a rig location is organized, and the legal theory that fits each kind of company.
The operator controls the lease and the well program. It may owe a duty under premises liability, the duty a party in control of a property or worksite owes to people working there. How far that duty reaches depends on the state's law and on how much control the operator actually kept over the work.
The drilling contractor owns and operates the rig, employs most of the rig-floor workers and controls rig equipment and day-to-day operations. For its own employees, workers' compensation rules in the state usually shape what is possible; for workers employed by other companies on location, ordinary negligence principles may apply.
Service and rental companies, such as cementing, wireline, directional drilling and rental tool providers, each control their own personnel and equipment. A worker employed by one company may have a civil claim against another company on location as a third party, depending on state law; workers' compensation from the employer does not necessarily bar a claim against someone else.
If a piece of equipment failed, the company that made or sold it may also be in the picture. Product liability is the legal theory that can hold a manufacturer or seller responsible for a product that causes injury because of a defect in its design, its manufacture or its warnings. A failure on the rig floor does not by itself prove a defect; the law asks whether there was a defect and whether it caused the injury.
Maintenance companies responsible for inspecting or maintaining equipment may owe a duty if a maintenance failure contributed to an injury.
Two further wrinkles explain why the paperwork between companies carries so much weight. First, a worker paid by one company is sometimes directed on the floor by another. When that happens, a question can arise about which company the law treats as the employer for that task, sometimes discussed as the borrowed-servant question, and how a state answers it can affect which rules apply. Second, the contracts between the companies on location may address which of them bears responsibility for certain losses. Those arrangements, often called indemnity clauses, are matters between the companies; this page does not describe how any state treats them.
For an injured worker, the practical point is that the list of companies on location that day is itself important information. A conversation with an attorney can cover how the contracts and site records bear on who controlled the task that led to the injury. The same control questions arise at other oilfield worksites, discussed on the site's page about pipeline site accidents, and in plant settings covered on the refinery explosion lawyer page.
