Paper: A Practical Comprehensive Geological And Engineering Study Of A Carbonate Reservoir North McElroy Unit Crane County, Texas

In 1973, a decision was reached to make a comprehensive joint geological and engineering study of the North McElroy Unit. It was hoped that the combined efforts would result in a more practical study to assist in the current waterflood operations. The objectives of this study were to (1) determine the different lithologies within the unitized interval and their associated physical properties; (2) establish reliable correlations and construct meaningful structure maps; (3) define the most efficient completion and production techniques; and (4) incorporate a more efficient water-injection program.
