Overview of Permian Basin Stacked Pays – the Gift That Keeps on Giving


Production from the Permian Basin of west Texas and New Mexico has sharply accelerated, recently exceeding 4 million BOPD.  The stratigraphic column of the region offers a unique combination of organic rich mudrocks, siliciclastics, and carbonates.  The current configuration of the basin resulted from tectonic activity during the Ouachita orogeny which formed two distinct basins – Midland and Delaware – separated by the Central Basin Platform.  Repeated cycles of high stand systems tracts and low stand systems tracts deposited over 3000 feet of stacked pays in some areas.  During high stands, allochthonous carbonate debris and organic mudrocks were deposited in the basins, while carbonate build ups flourished on platforms.  Low stand phases resulted in platform exposure/erosion while siliciclastic deposits via turbidity currents created lowstand wedges, channels, and fan complexes in the basins.  In addition, favorable thermal maturation and overpressure contribute to the prolific nature of these rocks.   The “Spraberry Trend” of the Midland Basin, once considered “the world’s largest uneconomic oil field” has transformed into some of the most valuable acreage in the world.

Steve is an AAPG and SIPES certified petroleum geoscientist with over thirty years of integrated oil & gas exploration and development experience in several basins in the U.S.  Steve has been responsible for drilling many wells in west Texas, southeast New Mexico, and the Michigan and Appalachian Basins.  After beginning his career in 1988 with Mobil Exploration and Production in Midland, TX, he worked the Michigan Basin for Savoy Oil and Gas.  In 1995, he founded Zody Geoscience and worked as an oil and gas prospector and consultant focusing on Trenton and Knox projects.  In addition, he evaluated and made recommendations on over $10 billion and 500,000 acres of prospective Permian Basin assets for SM Energy. He worked with Exploration & BD teams to generate petrophysical models, play maps, and EUR trends.  He has experience in both conventional and unconventional plays, 2D & 3D seismic interpretation, and enhanced recovery projects. Steve earned a B.S. in Geology from Ashland College in 1986 and an M.S. in Geology from New Mexico Institute of Mining & Technology in 1988.
