The Crinerville oil field, near Brock, Carter County, Oklahoma, occurs on a surface anticline in Pennsylvanian strata on the west side of, and faulted against, the Criner Hills. The reverse dip of 150 on the northeast side of the anticline disappears under a large part of the anticline in shales within 900 feet of the surface. Production comes from Pennsylvanian oil sands which overlap a truncated portion of the original Criner Hills of Ordovician limestone, now buried at a depth of more than 1,000 feet. The oil originated in the Pennsylvanian shales, and a small quantity migrated laterally into the Ordovician. The field was opened in January, 1922, and has produced between 1,000 and 1,500 barrels a day ever since. The total production to June 30, 1927, was slightly more than 2,300,000 barrels.
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.
