Inclined boreholes

WebMar 1, 1997 · The analytical solution for an infinitely long borehole in an isotropic, poroelastic medium, inclined to the far-field principal stresses, is presented. The solution utilizes a loading decomposition scheme which leads to three fundamental problems: a poroelastic plane-strain, an elastic uni-axial, and an elastic antiplane shear problem. WebThis, of course, will affect the behavior of inclined boreholes. Finally, the simulators use shear data also obtained by Chenevert for the samerock types. An extended Mohr-Coulomb criterion with a plane ofweakness is introduced. allowing both the cohesive strength andthe angle of internal friction to vary. The results are summarizedin Table 3.
