Parameter estimation in a reservoir engineering application

Abstract

Reservoir simulation models are used both in the development of new fields, and in developed fields where production forecasts are needed for investment decisions. When simulating a reservoir one must account for the physical and chemical processes taking place in the subsurface. Rock and fluid properties are crucial when describing the flow in porous media. In this paper the authors are concerned with estimating the permeability field of a reservoir. The problem of estimating model parameters such as permeability is often referred to as a history matching problem in reservoir engineering. Currently one of the most widely used methodologies which address the history matching problem is the E..
