Computation of pressure change in piecewise-homogeneous reservoir for elastic regime by indirect near-boundary element method

Using the indirect near-boundary element technique and time sequence scheme of the initial conditions, a numerical-analytical approach to finding the pressure change in the piecewise-homogeneous reservoir of arbitrary shape with mixed boundary conditions and ideal contact conditions at the interface of the media has been constructed. Using the created software, computational experiments have been carried out to estimate the errors of the discretization of near-boundary domains and the approximation of the mathematical model. The influence of piezoelectricity coefficients on pressure distribution in composite reservoirs has been studied.
