Anadarko basin statistical study: Gas well recovery versus depth in the Anadarko basin of western Oklahoma. Final report, July 1995-May 1996
Many gas exploration and exploitation strategies are based upon two basic premises. First, increased gas production with depth is merely a result of increased pressure due to increased overburden (depth). Second, reservoir quality typically degrades with depth. The Anadarko Basin was chosen to test the validity of these basic premises because of a large population of gas wells drilled representing a wide range of producing depths. It was demonstrated that increased gas well recovery typically exceeds the geopressure gradient. This trend holds true for the entire population of gas wells in the study area. The trend also holds for populations of wells grouped by lithology (sandstone, carbonate, and arkosic wash), by age of formation, and for completions having mixed lithologies. The results suggest that aggregate reservoir characteristics must improve with depth for gas well recovery to increase at a higher rate than compression due to the geopressure gradient.
