Kansas produced 98,429,869 barrels of oil and casinghead gasoline in 1945, which is the fourth highest yield in its history. Gas production amounted to 124,100,219,000 cubic feet. Operators showed a disposition to further hold back production especially after the termination of hostilities. Potential tests of many wells do not compare with those of previous years because operators are not desirous of building up allowables.

The Kansas exploration program slackened off in the latter part of the year from the active pace maintained during the war. Most significant discoveries were in the western part of the state from Mississippian limestone. First oil and gas production in Meade County, as indicated by wells in process of completion at the end of the year, opens up large areas in Oklahoma and Kansas on the north flank of the Anadarko basin.

The most extensively developed pool discovered during the year was the Ryan pool in Rush and Pawnee counties. Many minor extensions on the Central Kansas uplift were made. Development of Lansing-Kansas City production in Rooks and Sheridan counties improved prospects for profitable production in these areas in which heavy oil is generally found in Arbuckle dolomite. Drilling-up of many fields discovered during the war on 20-acre patterns was underway.

Developments of a technological nature were limited to increased use of gamma-neutron logs and electrical logs.

Exploration by the Amerada Petroleum Corporation of its large blocks in Dawes County, Nebraska, was the outstanding feature of a quiet year in those states of this province outside of Kansas.
