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, including 1800 wells with digital log data; 23,000 ft of quantified core analysis and description; and six decades of production data were integrated, analyzed, and output in a format that 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; a digital tops database for every well in the field; a digital cave location database; 2-D digital cross sections 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; and a 6.8 million cell, 3-D geologic model of the complete reservoir that includes log, core, and production data.
