Two boundary-element-method (BEM) formulations are proposed for the solution of pressure-transient problems in homogeneous, anisotropic reservoirs. Pressure solutions in arbitrary reservoir sources and/or sinks and a variety of constant and/or time-dependent boundary conditions can be generated. This technique is superior to numerical methods because it preserves the analytical nature of the solution and because numerical dispersion and grid-orientation effects are nonexistent. In this paper procedures for the convolution and Laplace-domain solution procedures are compared, and problems illustrating the various aspects of the BEM are solved.
