A Method for Determining Average Reservoir Pressure and Inflow Performance from Historical Surface Flowing Data in the Gomez (Ellenburger) Field, Pecos County, Texas

摘要

This paper presents the development and application of a method for determining average reservoir pressure and inflow performance parameters from historical surface flowing data for deep, high-temperature, gas wells located in the Gomez (Ellenburger) Field, Pecos County, Texas. This method provided suitable average reservoir pressure, improved p/z versus G_p data, and inflow performance optimization where a significant lack of reservoir data existed. The versatility, risk reduction, and cost-effectiveness of this methodology are also discussed.
