ABSTRACT:
Hydrocarbon liquids are recovered from run-of-mine oil-bearing rock composed primarily of limestone by separating the rock into a low-density fraction and a high-density fraction, contacting the low-density fraction with an organic solvent in an extraction zone thereby extracting the oil from the low-density fraction, and recovering the extracted oil from the organic solvent.
