ABSTRACT

ABSTRACT: This paper presents a simplified analysis of fluid pressure and solid stresses induced by fluid injection or pumping in a semi-infinite medium. The coupling of volumetric strain with the change in fluid mass has been partially decoupled using a poroelastic potential. The solutions of pressure and stresses in a semi-infinite space are obtained via the method of superposition. The resulting nonphysical surface shear stresses are numerically eliminated. Fluid sources of various geometries can be constructed to adapt to complex three-dimensional settings of underground disturbances.
