Oil has been a defining factor in Kansas’s history and economy for over a century. The state is home to significant hydrocarbon reserves, and the industry remains an active, consistent domestic oil and natural gas producer. These resources contribute substantially to the energy supply of the United States and have spurred technological innovation and created wealth across the state.
The Discovery and Early Days
The commercial history of oil production in Kansas began in the southeastern part of the state, following marginal finds in the 1860s. The first commercially successful oil well was drilled near Neodesha in Wilson County in 1892, establishing the foundation for the state’s petroleum industry. This discovery prompted Standard Oil Company to construct a refinery in Neodesha, igniting the region’s early production boom. Production accelerated in eastern Kansas, with fields like Independence contributing significantly to the national supply in the early 1900s.
A major turning point came in 1915 with the discovery of the El Dorado field in Butler County, northeast of Wichita. This field was one of the first in the nation successfully identified using the new science of petroleum geology, rather than random drilling. El Dorado rapidly became the largest single field oil producer in the United States, providing a substantial percentage of the nation’s oil during World War I. In 1918 alone, it produced nearly 29 million barrels of oil, representing about 9% of the total U.S. output that year.
Geographic Distribution and Geology
Oil and gas deposits in Kansas are distributed across several major subsurface geological structures, which dictate where drilling is most successful. The Central Kansas Uplift, a northwest-to-southeast trending arch in the rock layers, is historically the most prolific oil province in the state. This uplift brought older, oil-bearing formations closer to the surface, allowing petroleum to accumulate in structural traps. Primary reservoirs in this region are found in the Cambrian-Ordovician Arbuckle Group and the Pennsylvanian Lansing-Kansas City Group, which consist of porous limestone and dolomite.
In southwestern Kansas, the Hugoton Embayment, a northwest extension of the Anadarko Basin, is a significant producing area. While this region is most famous for the massive Hugoton Gas Field, it also holds substantial oil reserves. The oil here is often trapped in Mississian-aged carbonate formations and Pennsylvanian-aged sandstones. The Nemaha Uplift, a major subsurface feature, is responsible for trapping the massive reserves found in the historic El Dorado field.
Modern Production and State Revenue
The Kansas oil industry today is characterized by a high volume of active wells. The average Kansas oil well produces approximately two barrels of oil per day, classifying most of the state’s production as coming from “stripper wells.” These marginal wells collectively represent a significant portion of the total production and are important for maintaining the industry’s infrastructure. The state currently ranks as the 11th largest oil-producing state in the nation.
In recent years, the industry has maintained a steady output, with operators producing nearly 28 million barrels of oil and 143 billion cubic feet of natural gas in 2023. This activity generates billions of dollars in annual economic output and supports a large number of jobs. The oil and gas sector contributes millions of dollars to state and local governments through severance and ad valorem taxes. For example, the industry paid nearly $48 million in severance taxes to the state in 2023.
