I have not Practiced in Louisville since 2007. All reviews posted here are bogus and slanderous. They could not have been my patients as I was not in practice at the time they posted their reviews. Only God can Judge me.

Abstract:
A method, system and computer program product is disclosed for using a constrained pressure residual (CPR) preconditioner to solve adjoint models. A linear system of fluid flow equations comprising a plurality of variables that represent fluid flow properties in a geological formation of a subterranean reservoir is provided. Matrix (Ã), which comprises a transpose of a Jacobian matrix associated with the linear system of fluid flow equations, is constructed. A constrained pressure residual preconditioner Mis constructed responsive to the matrix (Ã). Matrix equation (Ã)y=d is then solved using the constrained pressure residual preconditioner M.
