Short answer
Usually not as a policy of their own. Control of well insurance, also called operators extra expense (OEE), is written for oil and gas well operators to pay the cost of regaining control of a wild well, plus resulting pollution cleanup and damage to the operator’s property, with options such as relief well coverage. What a service contractor needs is an MSA that leaves wild well costs with the operator, and a liability program that fits whatever the MSA does put on the contractor.
- Texas Chapter 127 does not apply to the cost of controlling a wild well, so the MSA language decides who pays.
- The IADC model drilling contract puts the cost of regaining control of a wild well, debris removal, and related claims on the operator. Your MSA may or may not follow it.
What control of well insurance covers
IRMI describes control of well as a specialty coverage that pays "for the expenses of bringing a blowout under control," for cleaning up resulting pollution, and for damage to the operator's property. Its entry on operators extra expense describes it as a specialized policy available to oil or gas well operators that "covers the cost of regaining control of a wild well," with pollution, stuck drill stem, evacuation, and care, custody, or control exposures available by endorsement. Relief well coverage, for the cost of drilling a new well to relieve pressure and help bring a wild well under control, is an optional add-on to OEE.
Texas law has its own definition. Chapter 127 defines a "wild well" as "a well from which the escape of oil or gas is not intended and cannot be controlled by equipment used in normal drilling practice."
Why it is an operator’s policy
The costs control of well pays are the costs of owning and operating the well: bringing it back under control, relief wells where that option is bought, pollution cleanup, and damage to the operator's own property. Those land on the operator because it is the operator's well. That is why IRMI frames OEE as a policy for well operators.
A service contractor's exposure is different. It is liability: injury to people, damage to other people's property, and pollution claims that come out of the contractor's own work. IRMI notes that coverage for liability to others' property damaged by a blowout or cratering is an optional coverage under the general liability policy, which is one reason oil and gas GL policies need a careful read.
How an MSA can move wild well costs onto you
Chapter 127 of the Texas Civil Practice and Remedies Code voids many oilfield indemnities for the other side's negligence. But Section 127.004 says the chapter does not apply to loss or expense arising from "personal injury, death, or property injury that results from the performance of services to control a wild well," or to the "cost of control of a wild well, underground or above the surface." Pollution and reservoir or underground damage are excluded from the chapter too.
So if your MSA makes you pay for well control, the statute will not cap it. The contract decides. The IADC model daywork contract shows the traditional allocation:
| Subparagraph | Risk | Model allocation | What to look for in your MSA |
|---|---|---|---|
| 14.12(a) | Cost of regaining control of any wild well | Operator | Any language making you pay well control costs when your work is involved |
| 14.12(b) | Debris removal, including the contractor’s rig, and property remediation | Operator | Whether debris removal or site restoration is pushed to you |
| 14.12(c) | Claims arising from the wild well, other than claims by the contractor group | Operator | Carve-outs for your negligence or gross negligence |
| 14.13(b) | Pollution from blowout, cratering, seepage, or flow from the well | Operator | Whether pollution from the well is shifted to you |
What to carry and what to ask
For most service contractors, the right program is the one that backs up the risks the MSA actually assigns to you:
- General liability with the oil and gas endorsements your work needs, including underground resources and equipment coverage if you work downhole.
- Contractors pollution liability for pollution the MSA puts on you, usually spills from your own equipment above the surface.
- Umbrella or excess limits that follow those policies.
If an MSA lists control of well insurance among contractor requirements, ask whether that requirement was meant for drilling contractors or operators, and whether it fits your scope. That is a reasonable point to raise. See whether you can negotiate operator insurance requirements.
Contract first, then insurance
Wild well clauses are legal language, and your attorney should review them. Our part is telling you, in plain terms, which of your policies would respond to what the clause says and where nothing would.
Common questions
Does my general liability policy pay to control a blowout?
GL is liability coverage for injury and damage to others. The cost of regaining control of the well is an operator expense that control of well insurance is built for. Whether any of your policies would respond to a contractual promise to pay well control costs depends on the wording, so ask before you sign.
Is a wild well indemnity void under Texas Chapter 127?
Not under Chapter 127. Section 127.004 says the chapter does not apply to the cost of controlling a wild well or to injury from services to control one. Other law may still apply, so your attorney should review the clause.
What is the difference between control of well and operators extra expense?
IRMI lists "cost of well control" as a synonym for operators extra expense. Both terms describe the operator’s coverage for regaining control of a wild well, with options such as relief well coverage.
Do well control specialty companies need different coverage?
Companies whose business is responding to wild wells have a different exposure from ordinary service contractors, and Chapter 127 treats injury from well control services separately. That is a specialized program and worth a dedicated review.
