Paper presented at the SPE/ISRM Rock Mechanics in Petroleum Engineering, July 8–10, 1998
Paper Number: SPE-47257-MS
... Abstract During exposure to different fluids and temperature gradients, the shear strength and the stiffness of shales may change because of changes in their chemical and physical properties. Time-dependent borehole stability models should incorporate these changes in order to capture actual...

... discontinuity theory. Deviations from the displacement discontinuity theory occur at glancing angles of incidence to the fracture. The anisotropy in the transmission coefficient is observed to be frequency dependent and results in an apparent frequency-dependent stiffness. P. 299 specific stiffness...

... dilatancy and conductivity. The model was found to be very sensitive to input data, especially for dilatant shear problems, depending on a complex interaction between normal load, maximum fracture closure, normal stiffness and the geological (stress) history. However, with normal movement becoming...

... problems. It was found that increasing intensity of rock-fluid interactions led to a decrease in brittleness of the mudrocks as well as reductions in their strengths and stiffnesses. Interestingly, on exposure to the most reactive fluids (water and 4% NaCl brine), the more competent Jurassic mudrock...
