Samples collected from 20 geographically widespread wells in the sparsely drilled Palo Duro Basin were analyzed for total organic carbon content (TOC). Highest values of TOC, up to 6.9 percent, occur in Upper Permian San Andres dolomite in the southern part of the basin.

The Upper Triassic Dockum Group of Texas and New Mexico is composed of 200 to 2,000 feet of complexly interrelated terrigenous clastic facies ranging from mudstone to conglomerate.

Integrated, detailed, and comprehensive study of the physical stratigraphy, tectonic history, hydrogeology, geomorphology, and resource potential of the Palo Duro and Dalhart Basins, Texas Panhandle, is part of a national evaluation of ancient salt basins as potential sites for isolation and mana
