Reservoir Modeling

iOGSolutions uses industry best software which encompasses a series of modules that attain their inherent power to accurately describe the reservoir by dividing it into discrete manageable three dimensional chunks, or “cells” of rock. Each cell is then assigned numerous properties such as porosity, permeability, saturation, anisotropy, etc. Together with each cell’s myriad properties, the macro-assemblage of all of the cells and their geometrical inter- relationship is captured within the structural and stratigraphic model. Once complete, the static model of the aggregate of millions of three dimensional grid-cells, each with its own reservoir properties, can be set in motion to simulate petroleum production in the oil-field.
