Crude Petroleum Extraction
NAICS 211120 · United States · 2022 edition
This industry comprises establishments primarily engaged in (1) the exploration, development, and/or the production of petroleum from wells in which the hydrocarbons will initially flow or can be produced using normal or enhanced drilling and extraction techniques or (2) the production of crude petroleum from surface shales or tar sands or from reservoirs in which the hydrocarbons are semisolids. Establishments in this industry operate oil wells on their own account or for others on a contract or fee basis.

Crude petroleum extraction establishments explore, develop, and operate oil wells to bring hydrocarbons to the surface — activities include drilling, well completion, production operations, and in some cases enhanced recovery techniques such as water or CO2 injection. Operators may work their own acreage or operate wells on behalf of working interest partners. Supporting infrastructure typically includes wellheads, separators, storage tanks, and gathering lines on or near the well pad.
Questions to investigate
- How many producing wells are operated, and what are the typical depths and formation pressures?
- Are any enhanced recovery operations in use, such as water flooding, CO2 injection, or steam injection?
- What is the nature of the extraction — conventional onshore, tight oil, tar sands, or other?
- What is the operator's loss history for the past five years, particularly any well control or environmental incidents?
