Asphalt and heavy oil occur in north Alabama in rocks in the Pride Mountain Formation, the Hartselle sandstone, and the Bangor limestone. Oil saturation in the Hartselle ranges from 1 to 60 percent and averages about 27 percent. The porosity ranges from 0.4 to 24.0 percent and averages about 13 percent. The impregnated interval ranges from 1 to 55 feet thick with an average of 21.3 Feet. The indicated-subeconomic petroleum resources of the Hartselle sandstone are estimated as being 1.18 billion barrels of oil in 350 square miles where the Hartselle is greater than 150 feet thick.
