Abstract: Reservoir Characterization of a Permian Giant: Yates Field, West Texas

Scott W. Tinker, Denise H. Mruk

The Yates Field reservoir characterization project provided the geologic framework, data, and tools that support the ongoing reservoir management of Yates Field. Geologic and engineering data from 1800 wells with digital log data, 23,000 feet of quantified core analysis and description, and six decades of production data, were integrated, analyzed, and displayed in a format which could be used for field evaluation, management, and simulation.

The Yates Field reservoir characterization products include: quantified, standardized, digital core descriptions for 118 cores in the field; 2-D digital cross section through every well in the field; 2-D structure and isochore maps for major and internal marker horizons, net and gross reservoir maps, net and gross shale maps, secondary calcite distribution maps, cave distribution maps, and fracture distribution maps; a 6.8 million cell 3-D geologic model of the complete reservoir that includes log, core, and production data.

The reservoir characterization project resulted in a quantified description of the heterogeneous matrix and fracture network in Yates Field. It is the efficient, ongoing management of this classic dual-porosity system that has stabilized production from this sixty-eight year old, 4.2 billion barrel field.
