Fluid Transport Properties of Rock Fractures at High Pressure and Temperature. Progress Report, July 1, 1976--June 30, 1977
Initial stages of a study on the fluid transport properties of rock at high pressure and temperature are reported. Emphasis is placed on the mechanical hydraulic interactions, in an attempt to clarify the process of fracture closure and its influence on fracture permeability. To determine the fluid transport properties of a fracture, the effect of surface roughness, geometry, and filling on fracture permeability was investigated. Permeability of these fractures was measured at various effective normal stresses at room temperature. The law of effective stress appears valid for fractures without filling but permeability of filled fractures is more sensitive to confining pressure than pore pressure. Permeability of smooth surfaces varied 5 to 0.5 darcys over a range of effective stresses from 0 to 3000 bars. Filled fractures were an order of magnitude more permeable. (ERA citation 02:048257)
