Garber Field, Garfield County, Oklahoma1
The Garber field, in T. 22 N., R. 3-4 W., Garfield County, Oklahoma, was discovered November 6, 1916, by the Exchange Oil Company's Hoy No. 1, in the northeast corner of Sec. 25, T. 22 N., R. 4 W., which had an initial production of 90 barrels of high-gravity oil from 1,138 to 1,150 feet in the Lower Permian. Eleven oil and gas sands were found in the subsequent shallow sand development. On April 6, 1925, the Sinclair Oil and Gas Company's Belveal 25, in the northeast corner of Sec. 24, T. 22 N., R 4 W., came in with an initial production of 2,600 barrels from the Ordovician limestone from 4,377 to 4,394 feet. This inaugurated another drilling campaign in which ten oil and gas horizons were exploited, and on March 19, 1927, the field had produced approximately 36,000,000 barrels from 23 horizons. The Permian and Pennsylvanian sediments exhibit very irregular lateral gradation in their shale, sandstone, and limestone phases, which condition greatly influenced petroleum accumulation. Portions of the Garber structure existed as a positive element or island from middle Tyner of Ordovician age until late Cherokee of Lower Pennyslvanian. Upthrusting of a continuous or oscillatory nature undoubtedly occurred in some minor degree throughout Pennsylvanian and early Permian time. A minimum of 1,000 feet of sediments is missing in the pre-Pennsylvanian unconformity, and the Pennsylvanian rocks show a minimum reduction of 700 feet from normal thickness. Criteria of tension fractures and fissures are present. Some conditions indicate possibility of vertical migration of oil and gas. The shallow oils are characterized by high gravity. Oil from the Ordovician rocks does not have the sulphur content characteristic of the “Siliceous lime” oil of the Tulsa-Osage district. The Ordovician oil accumulated in crystalline dolomite horizons.
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.
