Granite Wash Play Overview, Anadarko Basin. Discovery Thinking talk given by Ed LoCricchio at AAPG Annual Convention and Exhibition in Long Beach, California, April 22-25, 2012.
Introduction and Play Highlights
- Granite Wash play extends over 130 miles across 7 counties in the Anadarko Basin covering 2.5 million acres.
- Multi-stacked resource play concentrates value with potential of 40 Hz wells/section in Granite Wash.
- There are almost no federal leases.
- Established infrastructure is present.
- Landowners and state governments are industry-friendly.
- Range of cost of completed wells is $6-9MM.
- IP Range 50-3,500 BO and 3,000-30,000 MCFGPD.
- EUR Range 3-17 BCFE.
- Total Recoverable resources potential of 500 TCFE, (114 BBOE including NGL’s).
Conclusion
- Desmoinesian Granite Wash Play in the Anadarko Basin is one of the most active plays in the Continental United States.
- Clastics shed from the Wichita Mountain-Amarillo Uplift were deposited in the Anadarko Basin by sediment gravity flows,
creating a massive submarine sand complex.
- Anomalously pressured hydrocarbon system, both under- and overpressured.
- Produces both oil and gas, ratios vary laterally and vertically.
- Minimum of fifteen separate reservoirs.
- Advent of horizontal drilling technology and isolated multi-stage fracture stimulation has revolutionized play.
- New technology has enabled development of a giant field within a mature basin.
- As mapped today this field will take decades to develop, with new isolated reservoirs still being discovered.
