Abstract This paper describes a working gas injection pilot that is demonstrating additional oil recovery from a very mature field.This small, low cost pilot has been very valuable in understanding and demonstrating commercial viability of this enhanced oil recovery (EOR) process before larger scale implementation.After nearly 70 years of water drive production, this immiscible gas injection process has enabled conversion from viscous displacement water drive to gravity stable, film drainage behind an advancing gas front.The design, implementation and current pilot results are discussed as well as the role of three dimensional (3-D) geocellular and flow simulation models.Current full-field implementation project design efforts based on pilot performance and learnings are also described.
