Evaluating spontaneous hydraulic fracturing fluid imbibition and oil displacement method and apparatus
A test for evaluating spontaneous hydraulic fracturing fluid imbibition and oil displacement method and apparatus utilizing a composite core with a pressurized Amott cell test.
1. A method for evaluating spontaneous hydraulic fracturing fluid imbibition and oil displacement comprising the steps:
providing at least 10 composite cores made from drill cuttings ranges from 5% porosity to 20% porosity with an original oil in place of 62.7 ml;
providing a pressure cell for holding said at least 10 composite cores and fluids to be tested with a pressure range of 0 PSI to 10,000 PSI;
simulating fracture faces encountered in a hydraulic fracturing operations wherein imbibition forces of said fluid interact with at least 10 composite cores at all possible angles by pressurizing said pressure cell; and
evaluating spontaneous hydraulic fracturing fluid said imbibition and said oil displacement.
