Abstract: 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 ...

Abstract: This paper presents a theory and its application for post-fracture pressure-transient analyses. The proposed procedure, known as “impulse fracture test,” is an injection/falloff test designed for ...

Abstract: Solutions for the borehole problem based on Biot’s poroelasticity theory have shown that drilling through fluid saturated formations, gives rise to time-dependent stress and pore pressure fields in the vicinity of the ...

Abstract: This paper presents time-dependent poroelastic failure analyses of boreholes drilled in directions inclined to the far-field stress principal axes in fluid-saturated isotropic porous formations. The ...
