Paper: Case History of Waterflooding the Yates Sand, Ward County, Texas

The 600 acre Forest A. B. Gordon lease has produced 5,500,OOO bbl (9,167 B/A) of waterflood oil to March 1, 1966. This oil has been produced from the Yates formation and principally from, the Penn Bennett member. The primary recovery from this lease was 2,474,OOO bbl or 4,123 B/A, or a waterflood to primary ratio of 2.2 to 1. The A. B. Gordon waterflood is but one of many successful floods in the South Ward Field of southeastern Ward County, Texas, several of which have been reported on previously. It is the intent of this paper to review some of the information available at the start of waterflooding to see how reliable the various types of initial information would be in predicting waterflood response. Before going into these comparisons we will briefly look at the general character of the reservoir involved.
