The Rainbow Bend oil field is located near the west line of Cowley County, Kansas, about midway between Arkansas City and Winfield. Since its discovery in December, 1923, approximately 9,000,000 barrels of oil testing about 410 Be. gravity have been produced. The oil comes from sand at the very base of the Pennsylvanian, and production seems to be controlled by the distribution of this sand, which is lenticular. A well-defined, anticlinal dome is defined by the top of the Mississippian limestone, the oil sand occurring on the southeast flank of this fold. Development is controlled by one company; consequently, there is no overdrilling. Casinghead gasoline is an important product from the wells.

Structure of Typical American Oil Fields, Volume I
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 30 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. Fields include: McKittrick, California; Fairport, Kansas; Urania, Louisiana; Artesia, New Mexico; Burbank, Oklahoma; Cabin Creek, West Virginia; and Luling, Texas.
