A review of the data obtained in the several fields in Tennessee which are now pro-ducing or have produced oil in commercial quantities shows that in nearly all of them “structure” plays an essential part in the accumulation of oil and gas. Other factors are just as essential and must be taken into consideration. Nearly all of the fields have been mapped in sufficient detail to show the relative importance of the attitude of the beds. Only in the Spring Creek field is this factor apparently of little consequence.
The results of detailed mapping warrant the additional statement that the chances are overwhelmingly against wells located without regard to structure. Not all of the favorable structures drilled have produced oil, but all of the definitely unfavorable structures have been failures.
Anticlinal domes provide oil in the following fields: Celina and vicinity, including Mill Creek and Willow Grove, Spurrier-Riverton, Sumner County, and Tinsleys Bottom. The Glenmary field is on a low-faulted anticline, and the Bone Camp field near Sunbright is on a terrace. The data are none too satisfactory for the Spring Creek field, the Glenmary field, and part of the production of the Willow Grove and Spurrier-Riverton fields.
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.
