Play Analysis and Digital Portfolio of Major Oil Reservoirs in the Permian Basin: Application and Transfer of Advanced Geological and Engineering Technologies for Incremental Production Opportunities

Abstract

The Permian Basin of west Texas and southeast New Mexico has produced over 30 billion barrels (4.77 x 10^9 m³) of oil through 2000, most of it from 1,339 reservoirs having individual cumulative production greater than 1 million barrels (1.59 x 10^5 m³). These significant-sized reservoirs are the focus of this report. Thirty-two Permian Basin oil plays were defined, and each of the 1,339 significant-sized reservoirs was assigned to a play. The reservoirs were mapped and compiled in a Geographic Information System (GIS) by play. Associated reservoir information within linked data tables includes Railroad Commission of Texas reservoir number and district (Texas only), official field and reservoir name, year reservoir was discovered, depth to top of the reservoir, production in 2000, and cumulative production through 2000. Some tables also list subplays. Play boundaries were drawn for each play; the boundaries include areas where fields in that play occur but have less than 1 million barrels (1.59 x 10^5 m³) of cumulative production. This report contains a summary description of each play, including key reservoir characteristics and successful reservoir management practices that have been used in the play. The CD accompanying the report contains a PDF version of the report, the GIS project, PDF maps of all plays, and digital data files.

Oil production from the reservoirs in the Permian Basin having cumulative production greater than 1 million barrels (1.59 x 10^5 m³) was 301.4 million barrels (4.79 x 10^7 m³) in 2000. Cumulative Permian Basin production through 2000 from these significant-sized reservoirs was 28.9 billion barrels (4.59 x 10^9 m³). The top four plays in cumulative production are the Northwest Shelf San Andres Platform Carbonate play (3.97 billion barrels [6.31 x 10^8 m³]), the Leonard Restricted Platform Carbonate play (3.30 billion barrels [5.25 x 10^8 m³]), the Pennsylvanian and Lower Permian Horseshoe Atoll Carbonate play (2.70 billion barrels [4.29 x 10^8 m³]), and the San Andres Platform Carbonate play (2.15 billion barrels [3.42 x 10^8 m³]).
