ABSTRACT:
A method and apparatus for determining certain fluid flow parameters for naturally fractured media. Specifically provided is a method and apparatus to measure the flow rate, pressure drop, fracture aperture, fluid supply temperature and sample-loading force. A naturally fractured media core sample is obtained for testing and cut into a pair of core blocks having mating fractured forces. The fracture face of the core sample prepared in this manner, yields a more representative surface for flow study, eliminating the problem arising from the fact that most fractures cut across round core samples, resulting in an unnatural, elliptical surface for evaluation. A flow cell assembly is provided to receive the pair of core blocks and secure them during the measurement operation. The flow cell assembly permits adjustment of the fracture aperture to facilitate comprehensive evaluation.
