...K. Ben Naceur; J. C. Roeglers Summary The propagation of a set of hydraulically induced fractures is simulated with boundary-integral methods. The technique allows simulation of a single fracture in a varying stress field, as well as a set of arbitrarily oriented fractures. Applications relate...

... a hyperbolic rather than a linear relation between leakoff volume and t . We made laboratory fluid-loss measurements for a variety of fluids and rock materials to test this model. We monitored effluent volume produced by flowing a gel or suspension through a fully saturated core sample. We found that the new...

... displacement of a compressible reservoir fluid with a moving boundary between the two. Poiseuille flow is assumed in the fracture. We consider both Newtonian and non-Newtonian fluids with and without wall building. For non-Newtonian fluids, we assume the usual power-law relation between shear stress and shear...
