Relation of Production to Structure in Central Wilbarger County, Texas1
Oil accumulation in Wilbarger County, Texas, is due primarily to the presence of Pennsylvanian beds up warped by the Red River uplift of north-central Texas which extends east and west through the county. The stratigraphy may be briefly described as consisting of 1,100 feet of basal Permian, underlain by approximately 1,400 feet of undifferentiated Pennsylvanian, superimposed upon a Cambro-Ordovician and igneous mass. The important producing horizons, of which there are several in each pool, are of Pennsylvanian age. The discovery of the several pools of Wilbarger County may be directly traced to either surface or subsurface geology.
Figures & Tables
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.
