The discovery of oil in the Augusta field in 1914 presaged the entry of Kansas into the ranks of the important oil-producing states. Located on the Nemaha Granite Ridge, it preceded the discovery of the similarly located but more spectacular Eldorado field by more than a year. Anticlinal folding afforded a reservoir in the rocks of both the Pennsylvanian and Ordovician systems. Most of the oil produced has come from the Simpson sand and Arbuckle limestone of the Ordovician, and the production of gas has been limited wholly to the Pennsylvanian. The field is actually made up of two anticlines with a narrow intervening saddle dividing the producing area into the North Augusta pool and the South Augusta pool.
With an accumulative production estimated at 50 to 60 million barrels of oil at the end of the year 1946, the Augusta field ranked fourth among Kansas fields in number of barrels produced.

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.
