Suppose you are using a helium porosimeter to determine the matrix volume of a limestone core. the volumes of cells 1 and 2 are 6000 cm^3 each. a) find the final volume if cell 1 was initially charged with helium at 76.5 psig and the final pressure (after placing the core in cell 2, evacuating cell 2, and opening the valve) is 40.1 psig. (note that psig gives the gauge pressure that is equal to the absolute pressure minus 14.7 psi. b) from the final volume v2, find matrix volume. c) what is the bulk volume of the core in cm3 if its diameter is 9 cm and its length is 50 cm? d) what is the porosity of the core?
