摘要

Natural fractures are important conduits for fluid-flow and canrncontrol the deformational behavior of rock. The accuraternevaluation of natural fracture geometry in the subsurface isrndifficult because of the sampling problems inherent tornwellbores and indirect investigation methods such as seismic.rnBecause of these limitations in observational capability,rnpredictive models are needed to provide more constraint onrnnatural fracture characteristics. One approach is to look at thernmechanics of fracture propagation in sedimentary rock asrncontrolled by subcritical crack growth (also known as stresscorrosionrncracking). We have measured the subcriticalrnfracture properties of numerous sedimentary rocks, includingrncore samples from petroleum reservoirs, in conjunction withrndetailed petrographic analysis. Our preliminary resultsrnsuggest that carbonates and sandstones tend to have veryrndifferent subcritical fracture properties, and the variation inrnsandstone properties can be linked to grain and cementrnmineralogy and volume fractions.
