Ourcrop characterization of sandstone heterogeneity in Carboniferous reservoirs, Black Warrior basin, Alabama
Where production is currently declining, improved recovery strategies, such as waterflooding, injection, strategic well placement, and infill drilling may be used to increase production of liquid hydrocarbons from reservoir sandstone in the Black Warrior basin. Characterizing reservoir heterogeneity provides information regarding how those strategies can best be applied, and exceptional exposures of asphaltic sandstone in north Alabama enable first-hand observation of such heterogeneity. This report identifies heterogeneity in Carboniferous strata of the Black Warrior basin on the basis of vertical variations, lithofacies analysis. Results of lithofacies analysis and depositional modeling were synthesized with existing models of sandstone heterogeneity to propose methods which may improve hydrocarbon recovery in Carboniferous sandstone reservoirs of the Black Warrior basin. 238 refs., 89 figs. 2 tabs.
