Drilling Oil and Gas Wells
NAICS 213111 · United States · 2022 edition
This U.S. industry comprises establishments primarily engaged in drilling oil and gas wells for others on a contract or fee basis. This industry includes contractors that specialize in spudding in, drilling in, redrilling, and directional drilling.
Start the review with well control / blowout.
For Drilling Oil and Gas Wells, the saved research highlights well control / blowout, heavy equipment liability, workers' compensation / employer's liability. Confirm how these arise in the actual operation, what controls are used and whether additional services change the proposed coverage.
Questions to ask
- Is the operation exclusively onshore, or does it include any offshore, inland marine, or platform-based drilling?
- What types of formations and depths are typically drilled — shallow conventional, deep, or high-pressure/high-temperature?
- What are the standard master service agreement terms — particularly indemnity structure and insurance limits required by operators?
- Does the driller own and operate blowout prevention equipment, and what is the BOP maintenance and certification history?
- What is the prior loss history, including any well control events, blowout claims, or significant injury losses?
- For Drilling Oil and Gas Wells, what should the underwriter know about prior blowout or well control losses?
- For Drilling Oil and Gas Wells, what should the underwriter know about offshore or deepwater operations?
- For Drilling Oil and Gas Wells, what should the underwriter know about h2s (sour gas) exposure in formations drilled?

Contract oil and gas well drillers mobilize drilling rigs and crews to client-designated well sites, performing spudding, directional drilling, and redrilling services on a contract or fee basis. Operations involve heavy rotary drilling equipment, mud systems, blowout preventers, and specialized crews working in remote and often hazardous conditions. The driller does not own the well — they provide the drilling service to the operator.
