The tables below provide a structured reference for reviewing oilfield contractor COIs against typical MSA requirements. Use this as a starting framework - your specific MSA insurance exhibit governs, and requirements vary by operator, asset type, contractor scope, and jurisdiction.
For each contractor, work through each section in order. A single gap in a required coverage or endorsement is grounds to withhold site access until remediated.

Red Flags That Require Immediate Escalation
- Named insured on COI does not match MSA contracting entity
- Pollution policy is claims-made with retroactive date after work start
- Umbrella policy excludes pollution events
- XCU exclusion removal not confirmed for subsurface or hazardous work
- Any required coverage type absent from COI
- Any limit below MSA minimum - even by $1
- Insurer rated below A- by AM Best
- Agent cannot confirm endorsements within 48 hours
Frequently Asked Questions
Can I use this checklist for every oil and gas contractor?
This checklist covers the most common requirements in upstream oil and gas MSAs. Your specific MSA may require higher limits, additional coverages, or different endorsement language. Always use your actual MSA insurance exhibit as the governing document.
How do I track which contractors have completed each step?
At scale, a compliance platform provides dashboards showing per-contractor, per-coverage compliance status. For smaller programs, a spreadsheet tracking each checklist item by contractor and date of last verification is a minimum viable approach.
What if a contractor provides a COI that satisfies the checklist but the insurer is poorly rated?
AM Best rating below A- is a material risk factor. Even if limits are technically compliant, a financially unstable insurer may deny claims or be unable to pay them. Require A- or better as a precondition of approval.
How often does an oilfield contractor need to provide a new COI?
At minimum annually, aligned with policy renewals. Also required when a contractor begins work on a new asset, when scope of work changes materially, and any time a policy is cancelled or replaced.
This checklist is a tool, not a substitute for the MSA. Use it in conjunction with the governing contract to ensure every contractor on your assets meets your actual requirements.
