Low drilling density, variety and vintage of logs from wells drilled, and difficult regional correlations in Pennsylvanian rocks have contributed to poor oil-finding results in the Palo Duro basin. As a result the area has a "bad name" in industry. Stratigraphic

equivalents of Palo Duro basin rocks, ranging from the Ordovician to the Permian, produce in fringing areas or in nearby basins.

The region has had a complex geologic history. Source beds, reservoir-quality rocks, and large structures are present, but it appears that most oil to be found will be largely in stratigraphic traps.
