Abstract:
The success of oil recovery depends, among other factors, on the ability to provide reliable simulations of the reservoir performance. The reservoir dynamics are usually modeled by a distributed parameter dynamic system whose parameters represent the petrophysical properties of the reservoir. A proper characterization of those reservoir properties is fundamental for an accurate reservoir simulation. The petrophysical properties are highly heterogeneous and only a limited number of measurements are available at certain locations in the reservoir. Therefor, in ordet to obtain accurate prediction of the reservoir performance, it is essential to possess reliable estimates of the petrophysical properties in locations where measurements are not available. In this thesis we present some petrophysical properties of the reservoir that are effective on its permeability and then in order to address the problem in a geometrical fasion(i.e, in terms of Ω), we use an integral formulation of the reservoir model, and we study LM,GB methods.
