The latest oil and gas facts and figures from Wyoming — including development, taxes, employment and more.

Exploration

140
Years of Exploration in Wyoming
1884
First Oil Well Drilled — near Lander, WY
25,830 ft
Deepest Vertical Well — Madden Formation
40,000+ ft
Longest Permitted Well (Measured Depth)

With the development of horizontal drilling, well depth is measured differently with both True Vertical Depth (TVD) — the depth below the surface — and Measured Depth (MD), which is the total length of the well bore including both vertical and lateral depth.

Refining & Transportation

1895
Wyoming's First Refinery — Casper

Barrels/Day Refining Capacity (2022)
2nd
Largest Net Energy Exporter in the U.S. (after Texas)

Wyoming's first refinery was constructed in Casper in 1895. In 2022 there were 4 operating refineries in the state with a capacity to refine 125,850 barrels of crude oil each day. In 1981 there were 14 active refineries in the state.

The first crude oil pipeline was constructed in 1911. Today, there are approximately 100 companies operating more than 25,000 miles of pipelines in Wyoming, not including all gathering systems or all inactive or abandoned pipelines.

Pipelines are located in all of Wyoming's 23 counties and carry crude, natural gas, natural gas liquids, carbon dioxide, and petroleum products.

According to the Energy Information Agency, Wyoming produces nearly 12 times the amount of energy it consumes, making it the second-largest net exporter of energy after Texas.

Property Taxes

Oil and gas production, by itself, accounted for over 40% of the total property taxes levied in Wyoming and approximately 80% of the property taxes levied on all minerals.

Minerals are the only class or kind of property in Wyoming valued and taxed at 100% of their actual value. Minerals are also the only class or kind of property which pay two direct taxes — property and severance.

Property Taxes Levied — 2022 Mineral ProductionAmount
Crude Oil$485,844,982
Natural Gas$393,975,948
Oil and Gas Total$879,820,930
Coal$166,969,468
Trona$37,072,564
All Others$9,079,352
Total All Minerals$1,092,942,314
Total All-State Property Taxes Levied$2,199,769,606

Royalties

  • In addition to property and severance taxes, Wyoming collects a royalty for petroleum produced on state-owned lands, along with certain fees and rentals.
  • The state also receives one-half of the royalties paid to the federal government for leasing, production, and fees on federal lands.
