Using a geology-based assessment methodology, the U.S. Geological Survey estimated means of 147.4 trillion cubic feet of undiscovered natural gas, 2.4 billion barrels of undiscovered oil, and 2.96 billion barrels of undiscovered natural gas liquids in Jurassic and Cretaceous strata in onshore lands and State waters of the Gulf Coast.

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.

"These new findings underscore the challenge of predicting whether oil or gas will be found in frontier areas and the importance of analyzing the geologic characteristics and history of an area in order to understand the oil and gas resources,” explains USGS Director, Dr. Marcia McNutt.

Well tests in Wainwright, Alaska, confirmed the gas content of the coal reservoir within this area. If producible, the Wainwright coal bed contains sufficient gas to serve as a long-term source of energy for the community.

This economic analysis of the Alaska North Slope resource assessments is based on undiscovered assessed accumulation distributions represented by the aggregation of all four assessed areas and incorporates updates of costs and technological and fiscal assumptions used in the initial economic analysis that accompanied the geologic assessment of each study area.
