Abstract
Methods and apparatus are disclosed for determining oil saturation in sponge coring using solvents which dissolve substantially all of the oil but none of the sponge. Two classes of such solvents are specified. One is aprotic, and the resultant concentration of oil in it is measured by proton NMR spectroscopy. The other has no C--H bonds, and the resultant concentration of oil in it is measured by infrared spectroscopy.
