METHOD FOR DETERMINING POROSITY, CLAY CONTENTAND MODE OF DISTRIBUTION INGAS AND OIL BEARING SHALY SAND RESERVOIRSAbstract of the DisclosureA method for determining formation poros-ity, volume of clay content, and mode of distributionin gas, oil, and water bearing shaly sand reservoirsprovides solutions regardless of whether gas and oildensities are known or unknown, whether or not thereis invasion of borehole fluids into the connatefluids, and whether or not there is dispersed clayonly or both dispersed and laminated clays arepresent.
