Prototype for the optimization of CO2 injection wells placement in a reservoir

Abstract This paper provides a methodology that allows to estimate in a limited time the optimal number and location of CO2-injector wells for a given reservoir. A quality map, based on intrinsic properties of the reservoir, helps to build a sampling of well coordinates, chosen denser in the potentially good regions to inject CO2, and looser otherwise. Each of these sampled well coordinates are simulated with the help of a reservoir simulator. The results given by these elements are then interpolated by kriging and allow to determine the best position and number of injection wells.
