Abstract
A good estimation of permeability is important for enhanced reservoir management and accurate simulation of the reservoir. This paper presents a way of estimating the permeability of a homogeneous reservoir based on transient pressure and temperature data. To obtain the data we used numerical solutions of mass balance, energy equation, and Darcy's law. The study was divided into two stages, initially, synthetic data is obtained by using a solution of a coupled system of conservation equations where here this procedure is called as the direct problem and then the estimation of permeability is obtained by using an inverse problem considering a perturbation of permeability as a noise source. To solve the inverse problem we used the secant method combined with the relative error between the expected result and the estimated result. The results show how the inverse problem properly used can estimate accurately the permeability of the reservoir.
