NAICS 5  Digit Industry 21111 – Oil and Gas Extraction

Definition of NAICS 5 Digit Industry 21111: 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.

Industry Breakdown for North American Industry Classification System

NAICS codes are broken down by digit. The broadest description starts with the 2 digit sector codes. The 3 digit subsector codes are more specific, then the 4 digit industry group, 5 digit industry (Where you are now), and the most specific is the 6 digit NAICS code. If the code on this page does not describe the industry of the business in question, then select the largest applicable code below. From there, follow through the progression of smaller digits to the larger digits in order to obtain the most specific 6 digit classification.

  • Sector 21: Mining, Quarrying, and Oil and Gas Extraction
    • Subsector 211: Oil and Gas Extraction
      • Industry Group 2111: Oil and Gas Extraction
        • Industry 21111: Oil and Gas Extraction
          • 6 Digit Code(s) NAICS 211111: Crude Petroleum and Natural Gas Extraction
          • 6 Digit Code(s) NAICS 211112: Natural Gas Liquid Extraction
