Geology and Development of Washita Creek Field

William D. Tutten


The Washita Creek Gas Field is in southeastern Hemphill County, Texas approximately 20 miles southeast of the town of Canadian. Geologically the field is in the deep western sector of the Anadarko Basin and north of the Basin Axis. The producing area is on a dome shaped anticlinal feature slightly elongate in a northwest southeast direction.

The deepest test well in the Texas Panhandle has been drilled into the Arbuckle Formation on the Washita Creek structure. Abnormally high pressure gradients are associated with the Morrow shale and sandstone sequence resulting in higher drilling costs.

Hunton gas production was discovered in 1966, and a Morrow gas reservoir was penetrated in 1960. Gas from the Morrow was placed on production in 1969 and from the Hunton in 1970.

There are five Morrow and seven Hunton gas wells. The Pennsylvanian Upper Morrow Sand, which produces in four wells, lies at the 13,600 foot level in the subsurface. Five Lower Morrow Sand members are between 15,200 and 16,200 feet. One well produces from Lower Morrow Sandstone. Primary gas production is from the Siluro-Devonian (Hunton) reservoir at depths between 19,300 and 20,400 feet. The Hunton Group of limestone and dolomite averages 500 feet in thickness. Porosity developed as a result of dolomitization in the Hunton. The porosity is stratified and is mostly inter crystalline in nature with some vugs. Loss of permeability contributes to the trapping mechanism. Washita Creek wells have established large gas reserves.
