Industries in the Oil and Gas Extraction subsector operate and/or develop oil and gas field properties. Such activities may include exploration for crude petroleum and natural gas; drilling, completing, and equipping wells; operating separators, emulsion breakers, desilting equipment, and field gathering lines for crude petroleum and natural gas; and all other activities in the preparation of oil and gas up to the point of shipment from the producing property. This subsector includes the production of crude petroleum, the mining and extraction of oil from oil shale and oil sands, and the production of natural gas, sulfur recovery from natural gas, and recovery of hydrocarbon liquids.
Establishments in this subsector include those that operate oil and gas wells on their own account or for others on a contract or fee basis. Establishments primarily engaged in providing support services, on a fee or contract basis, required for the drilling or operation of oil and gas wells (except geophysical surveying and mapping, mine site preparation, and construction of oil/gas pipelines) are classified in Subsector 213, Support Activities for Mining.
2111 Oil and Gas Extraction
21111 Oil and Gas Extraction
This industry comprises establishments primarily engaged in operating and/or developing oil and
gas field properties and establishments primarily engaged in recovering liquid hydrocarbons from
oil and gas field gases. Such activities may include exploration for crude petroleum and natural
gas; drilling, completing, and equipping wells; operation of separators, emulsion breakers,
desilting equipment, and field gathering lines for crude petroleum and natural gas; and all other
activities in the preparation of oil and gas up to the point of shipment from the producing
property. This industry includes the production of crude petroleum, the mining and extraction of
oil from oil shale and oil sands, the production of natural gas, sulfur recovery from natural
gas, and the recovery of hydrocarbon liquids from oil and gas field gases. Establishments in this
industry operate oil and gas wells on their own account or for others on a contract or fee basis.
Cross-References. Establishments primarily engaged in -
- Performing oil field services for operators on a contract or fee basis - classified in Industry 21311, Support Activities for Mining;

211111 Crude Petroleum and Natural Gas Extraction
This U.S. industry comprises establishments primarily engaged in (1) the exploration, development
and/or the production of petroleum or natural gas from wells in which the hydrocarbons will
initially flow or can be produced using normal pumping 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 and gas wells on their own account or for
others on a contract or fee basis.
