New maps of oil and gas fields available from the Kansas Geological Survey

LAWRENCE – The nearly 1,800 new oil and natural gas fields named in Kansas between 2009 and early 2019 are now shown – along with more than 6,000 fields discovered earlier – on a series of updated maps available from Kansas Geological Survey.

The series includes 12 regional maps, each covering approximately 90 by 55 miles and named after cities within its perimeter, including Wichita, Dodge City, Goodland, and Lawrence. The locations and names of the oil and gas fields as well as the geographic names and boundaries are shown on the maps. The 7,818 field locations also appear on a revised statewide wall map.

“These maps show, at a glance, where oil and gas was discovered and produced in Kansas and where it was not,” said Mike Dealy, director of the KGS office in Wichita. “They provide useful information to the oil and gas industry, landowners, mineral rights holders, researchers and the public.

Kansas became a major oil-producing state with the discovery of the El Dorado field northeast of Wichita in 1915. Maps show that much of the following oil-producing fields extend from south-central Kansas to northwest of Hays along the central Kansas Uprising. , an underground geological structure. Ellis County, which includes Hays, has been the state’s largest producer county for the past 52 years, with only three of them.

Since the maps were last revised in 2009, much of the new oil and gas activity has taken place along the Oklahoma border, primarily in Harper and Sumner counties. In 2013, increased drilling activity from an underground group of petroleum rocks known as the Mississippian Limestone Game crossed the state border into Kansas.

“During the boom in south-central Kansas, more than 700 wells were drilled in a county level just north of the Oklahoma state border between 2013 and 2015,” said Dave Newell, geologist by KGS. “The production of oil and natural gas in the region has increased rapidly. “

Production in the south-central region has since slowed considerably due to the geological characteristics of the Mississippian limestone zone.

The largest concentration of natural gas production on the charts is in southwestern Kansas, in the Hugoton gas region, once the largest natural gas field in North America. Production there peaked in 1970 before declining, in large part due to exhaustion.

“Unlike the 2009 map, which did not distinguish between the Hugoton gas area and the deeper Panoma gas area, the 2019 map shows the boundaries of each,” said KGS cartographer John Dunham.

Underlying much of southwestern Kansas, the Hugoton and Panoma produce from different formations at different depths.

The recently revised maps also now include the boundaries of two large coal gas zones in eastern Kansas, where natural gas is produced from shallow coal deposits. In the early 2000s, gas production in these regions increased as natural gas prices increased. After the price peak in 2008, production declined there.

The Kansas Geological Survey is a research and service division of the University of Kansas. Its main office in Lawrence is the repository for more than 450,000 oil and gas files submitted or donated to the Crown. The KGS Wichita office maintains geological samples from more than 144,000 oil, gas and exploration wells drilled in Kansas. Data from individual fields and wells are available via an online interactive oil and gas map at

The new regional maps of the oil and gas fields and the map of the entire state are available from the Kansas Geological Survey, 1930 Constant Ave., Lawrence, KS 66047-3724 (phone 785-864-3965) and at 4150 W. Monroe St., Wichita, KS 67209-2640 (phone 316-943-2343).

The cost is $ 10 per regional card and $ 20 for the statewide card, plus shipping and handling charges. Learn about shipping and handling charges and, for Kansas residents, sales tax.
