TESTING APPARATUS FOR APPLYING A STRESS TO A TEST SAMPLE
A testing apparatus which is suitable for applying a stress load to a test specimen is provided. The testing apparatus may be used to simulate lithostatic stress on a test specimen, which may be, for example, a portion of a geologic formation. The testing apparatus may also be used in a method of evaluating the expected production of fluids obtainable from in situ pyrolysis of oil shale.
