Assessment of Undiscovered Oil and Gas Resources of the Anadarko Basin Province

USGS Publication: Fact Sheet 2011–3003
The U.S. Geological Survey, using a geoscience-based assessment methodology, estimated mean technically-recoverable undiscovered continuous and conventional resources that total 495 million barrels of oil, 27.5 trillion cubic feet of natural gas, and 410 million barrels of natural gas liquids.

Connectivity Equation and Shaly-Sand Correction for Electrical Resistivity

USGS Publication: Scientific Investigations Report 2011–5005
In this study, the connectivity equation (CE), which is a new approach to model non-Archie rocks, is used to correct for the clay effect and is compared with results using the Waxman and Smits method. The CE presented here requires no parameters other than an adjustable constant, which can be derived from the resistivity of water-saturated sediments.

Sedimentology and Reservoir Heterogeneity of a Valley-Fill Deposit

A Field Guide to the Dakota Sandstone of the San Rafael Swell, Utah

USGS Publication: Scientific Investigations Report 2010–5222
Valley-fill deposits form a significant class of hydrocarbon reservoirs in many basins of the world. Maximizing recovery of fluids from these reservoirs requires an understanding of the scales of fluid-flow heterogeneity present within the valley-fill system.

Assessment of Coal Geology, Resources, and Reserves in the Northern Wyoming Powder River Basin

USGS Publication: Open-File Report 2010-1294
The total original coal resource in the Northern Wyoming Powder River Basin assessment area for all 24 coal beds assessed, with no restrictions applied, was calculated to be 285 billion short tons. Available coal resources, which are part of the original coal resource that is accessible for potential mine development after subtracting all restrictions, are about 263 billion short tons (92.3 percent of the original coal resource). With a discounted cash flow at 8 percent rate of return, the coal reserves estimate for the Northern Wyoming Powder River Basin assessment area is 1.5 billion short tons of coal (1 percent of the original resource total) for the seven coal beds evaluated.
