Verifying a contractor's insurance in the oil and gas industry requires more than reading the ACORD 25. The coverages that matter most in upstream - pollution liability, control of well, XCU exclusion removal, umbrella follow-form - are either invisible on the certificate or require separate confirmation with the insurer.
This guide walks through the complete verification process for an oilfield contractor, from MSA requirements to site access approval.
Before You Start: Pull the MSA Insurance Exhibit
Every verification begins with the governing contract. The MSA insurance exhibit specifies exactly what coverage types, limits, endorsements, and policy form requirements the contractor must meet. If you don't have the exhibit open when reviewing a COI, you cannot perform a complete compliance check.
For each contractor, note the following from the MSA exhibit before reviewing the COI:
- Every required coverage type and minimum limit
- Required endorsements (additional insured, waiver of subrogation, XCU, cross-liability)
- Required policy forms (occurrence vs. claims-made for pollution)
- Special coverages required for this contractor's scope (control of well, professional liability, builders risk)
- Additional insured entities (operator, joint venture partners, landowners)
Step 1: Verify the Contractor Entity
The named insured on the COI must match the legal entity that signed the MSA. In oilfield contractor networks, entity mismatches are common:
- Parent company is the contracting entity but the COI names an operating subsidiary
- Contractor operates under multiple entities; the COI names the wrong one
- Sole proprietors list personal names; the MSA names a business entity
How to verify: Confirm with the contractor and their agent that the named insured on every policy is the entity that will be performing work and signing the site access agreement. Request documentation if there is any discrepancy.
Step 2: Check Basic Coverage Types and Limits
Compare the COI face to the MSA requirements line by line:
| Coverage | MSA Requires | COI Shows | Match? |
|---|---|---|---|
| General Liability (per occurrence) | $2,000,000 | ___ | ☐ |
| General Liability (aggregate) | $4,000,000 | ___ | ☐ |
| Auto Liability | $1,000,000 | ___ | ☐ |
| Workers' Compensation | Statutory | ___ | ☐ |
| Employers' Liability (each) | $1,000,000 | ___ | ☐ |
| Pollution Liability | $2,000,000 | ___ | ☐ |
| Control of Well | $5,000,000 | ___ | ☐ |
| Umbrella / Excess | $10,000,000 | ___ | ☐ |
Any gap at this stage stops the process - the contractor cannot be approved until the gap is remediated.
Step 3: Verify XCU Exclusion Removal (GL Policy)
This check cannot be done from the COI alone. Contact the contractor's GL insurer or agent and request written confirmation that:
- Explosion hazard exclusion is not in force
- Collapse hazard exclusion is not in force
- Underground damage exclusion is not in force
Standard commercial GL policies often include these exclusions by default. Oil and gas MSAs almost universally require their removal. The absence of this confirmation is a material compliance gap regardless of what the COI limit shows.
Alternative: Request the GL policy declarations page and the exclusions schedule. Review for CG 2109 (explosion), CG 2110 (collapse), CG 2111 (underground damage), or equivalent forms.
Step 4: Verify Pollution Liability Policy Terms
Pollution is the highest-stakes coverage in oilfield contractor compliance. Verification goes beyond the limit:
Step 4a: Confirm policy form. Is it occurrence or claims-made?
- Occurrence form: incidents during the policy period are covered whenever the claim is filed
- Claims-made form: requires a retroactive date review and extended reporting period planning
Step 4b: If claims-made, confirm the retroactive date. The retroactive date must be on or before the date the contractor first performed work on your assets. A retroactive date after the work start date means prior work incidents have no coverage.
Step 4c: Confirm coverage scope. The pollution policy should specifically cover:
- Hydrocarbon releases
- Produced water and drilling fluid spills
- Third-party bodily injury and property damage from pollution events
- Regulatory cleanup costs
Request a certificate supplement or agent letter confirming these coverage items.
Step 4d: Confirm operator is additional insured on the pollution policy. Additional insured status on GL alone is insufficient. The operator must be named on the pollution policy to access coverage for pollution-related claims.
Step 5: Verify Umbrella Follow-Form Status
The umbrella appears on the COI as a large number - $10M, $25M - that looks reassuring. But an umbrella that excludes pollution does not provide $10M or $25M of coverage for pollution events. It provides $0 for those events.
Step 5a: Request the umbrella policy declarations page.
Step 5b: Review the exclusions section for pollution exclusions, employers' liability limitations, or any line where the umbrella does not follow form.
Step 5c: Confirm the umbrella sits over the pollution policy if the MSA requires it.
Step 5d: Confirm the self-insured retention (SIR) is within acceptable limits. Some umbrellas have large SIRs that reduce effective coverage for smaller incidents.
Step 6: Verify Endorsements
For each required endorsement, confirmation must come from the insurer or agent - not just from the certificate description field:
| Endorsement | How to Verify |
|---|---|
| Additional insured (GL, auto, umbrella) | Confirm with agent; request endorsement form |
| Additional insured (pollution) | Confirm with agent; pollution AI is often separate |
| Waiver of subrogation (all policies) | Confirm with agent for each policy including WC |
| Primary/non-contributory AI | Confirm language in AI endorsement |
| XCU exclusion removal | Confirm with agent; request declarations |
| 30-day cancellation notice | Confirm policy provision; many provide only 10 days |
Step 7: Verify Scope-Specific Coverage
For specialized scopes of work, additional verification is required:
Subsurface operations (drilling, completions, workover): Confirm control of well limit is appropriate for the specific well type (depth, pressure, formation). Some MSAs specify COW limits by well type or production profile.
Offshore or near-shore operations: Confirm USL&H endorsement on workers' compensation. Confirm Jones Act coverage for seamen. Confirm marine general liability if vessels are involved.
Hot work, explosives, or high-hazard operations: Confirm GL policy covers the specific hazard. Some GL policies exclude demolition, blasting, or high-hazard construction - verify these exclusions are not in force.
Step 8: Document and Approve (or Deny)
Complete documentation includes:
- Date of review
- Reviewer name and role
- COI received date
- Each coverage type checked and result
- Endorsement verifications completed
- Any gaps found and remediation steps
- Approval or denial decision
This documentation is your legal record of due diligence. In the event of an incident and coverage dispute, it demonstrates the operator conducted a reasonable compliance review before granting site access.
Frequently Asked Questions
What is the fastest way to complete a full oilfield COI verification? There is no shortcut that maintains quality. The process above typically requires 45-90 minutes of manual review per contractor. For programs with more than 50 active contractors, automation through a contract-aware platform is the only way to maintain this level of rigor at scale without proportional staff increases.
Can I rely on a pre-qualification system's approval as my verification? No. Pre-qualification systems confirm a COI is on file and meets their templates. They do not compare against your MSA exhibit or verify oil-and-gas-specific policy provisions. Use pre-qual as a starting gate, not a final approval.
What if the contractor's insurer won't provide endorsement confirmations? This is a red flag. Legitimate insurers and agents will provide written confirmation of endorsements on request. An insurer or agent that refuses to confirm policy details is either non-cooperative or the coverage does not exist as represented on the COI.
How do I handle contractors who are current in the pre-qual system but whose MSA compliance hasn't been reviewed? Treat them as unreviewed and require a COI review before site access is granted. Pre-qual currency and MSA compliance are separate determinations.
Oilfield contractor insurance verification is a multi-step process that requires going well beyond the COI face. The checks that matter most - XCU, pollution form, umbrella follow-form - are invisible without policy-level review.
