ABSTRACT
Lower Skinner Valley Fill Sandstones: Attractive Exploration Targets on the NE Oklahoma Platform
Puckette, Jim, Oklahoma State University
High-volume oil and gas accumulations occur in Desmoinesian Lower Skinner valley fills located on the NE Okla-
homa Platform. Sandstones within these paleovalleys produce oil and gas from traps that combine two key compo-
nents: porous reservoir and anticlinal folding. Skinner valleys formed in response to a drop in sea level. Lowstand
stream erosion formed the resultant valleys, which form narrow, linear trends. Lower Skinner valleys that eroded
through underlying "Skinner" highstand deltaic and marginal marine strata resulted in the juxtaposition of fluvial
Lower Skinner sandstone on the partially eroded Pink Limestone marker. In some cases, incision removed the Pink
Limestone, and Skinner valley fill sediments were deposited directly on Red Fork strata.
The heterogeneous nature of valley fills complicates oil and gas recovery. High-resolution stratigraphic correlation
using wireline logs is useful in identifying potential isolated compartments. In the NW Sooner Valley Field in cen-
tral Payne County, compartmentalization is confirmed by fluid and pressure data.
Porosity in valley fill sandstones is mostly secondary and resulted from the dissolution of feldspar and metamor-
phic rock fragments. The combination of thicker sandstone, high porosity (16 to 20%) and permeability (>200 md),
and favorable trapping conditions, results in oil recoveries that often exceed 200 MBO per well. The shallow drill-
ing depths on the NE Oklahoma Platform make these sandstones attractive exploration targets.
