Abstract

In-situ combustion process has been implemented in Santhal field on commercial scale since 1997 for enhancing the recovery of heavy oil. During performance reviews of the wells involved in EOR process it was observed that behavior of some of the wells does not confirm to prediction/ anticipation based on the existing geological model. This paper deals with modification/up gradation of existing geological model incorporating faults interpreted from 3D seismic data. The revised/improved geological model explains the fluid movement behavior more satisfactorily and can be used for placement of future wells for further enhancement of production
