The Fouke field is near the western margin of the Gulf Coastal Plain in Miller County, Arkansas. Subsequent to seismic exploration, the field was discovered, June 6, 1940, upon completion of an oil well in the Paluxy formation. On the basis of subsurface geology, a second productive formation was discovered on March 6, 1947, upon completion of a gas-condensate well in the Kilpatrick limestone of the Rodessa formation. Cumulative production from the Paluxy formation through January, 1947, was 3,568,137 barrels from 46 wells having an average depth of 3,550 feet. The total area capable of producing is an estimated 1,600 acres.
The accumulation of gas and oil is believed to be due to closure on both the upthrown and downthrown sides of a northeast-southwest-trending fault zone. The fault zone is a part of the arcuate graben system extending west and east across southwest Arkansas. Closure in the Paluxy formation is approximately 150 feet.
Development has been on staggered 20-acre spacing except when restricted to 40-acre units by Petroleum Administration of War regulations. The Paluxy crude oil is black, sweet-smelling, and has a corrected gravity of 32.1° A.P.I.

Structure of Typical American Oil Fields: A Symposium of the Relation of Oil Accumulation to Structure
Modern petroleum geology in the United States had its beginning in the first decade of the 20th Century when the U.S. Geological Survey began mapping the structure of the rocks in and near old fields in order to discover the various types of structural conditions under which oil and gas are trapped. Structural geology has evolved as a branch of the broader science far more rapidly than have methods of mapping the attitude of rocks at the surface. This volume, published in the late 1920s, was designed to afford authoritative and modern descriptions of the structure of typical oil fields in the United States. Each of the 39 fields contained here is described by an author who is intimately familiar with the available data. The relationship of structure at the surface and at depth for different terranes is clearly set forth wherever the strata are not parallel. The volume concludes with a summary paper on the role of geologic structure in the accumulation of petroleum. Fields include: Florence, Colorado; Stephens, Arkansas; Kevin-Sunburst, Montana; Bradford Pennsylvania; and Salt Creek, Wyoming.
