STRATIGRAPHIC FRAMEWORK AND CONTROLS ON PENNSYLVANNIAN GRANITE WASH PRODUCTION, ANADARKO BASIN, TEXAS AND OKLAHOMA
Granite Wash sediments are the result of detritus shed from the Wichita Mountain-Amarillo Uplift into the basin. This deep water deposit can be divided into at least fifteen reservoirs by mapping regionally correlative flooding surfaces. This complex stratigraphy results from the interplay between tectonically controlled Granite Wash sediments from the south and shelf derived sediments from the north. Detailed net sand maps and regional cross-sections demonstrate these stratigraphic and structural controls on reservoir extents and lateral continuity of this important resource.
