Shale gas is a key source of onshore domestic energy for the United States and production of this resource is increasing rapidly. Development and extraction of shale gas requires hydraulic fracturing, which entails horizontal drilling, perforation of steel casing and cement grout using explosive charges, and expansion of fractures using fluids under high pressure. Concern over potential environmental effects of shale gas development is growing and based on a recent review there is very little information in the scientific literature on potential environmental effects of hydraulic fracturing. We propose to conduct the first broad scale, data-based assessment of the potential effects of hydraulic fracturing on water...

This data release contains the boundaries of assessment units and input data for the assessment of oil and gas resources in the Upper Cretaceous Austin Chalk Group and Tokio and Eutaw Formations in Texas, Louisiana, Mississippi, Alabama, Florida and Arkansas. The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within the context of the higher-level Total Petroleum System. The Assessment Unit is shown herein as a geographic boundary interpreted, defined, and mapped by the geologist responsible for the province and incorporates a set of known or postulated oil and (or) gas accumulations sharing...

The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within the context of the higher-level Total Petroleum System. The Assessment Unit is shown herein as a geographic boundary interpreted, defined, and mapped by the geologist responsible for the province and incorporates a set of known or postulated oil and (or) gas accumulations sharing similar geologic, geographic, and temporal properties within the Total Petroleum System, such as source rock, timing, migration pathways, trapping mechanism, and hydrocarbon type. The Assessment Unit boundary is defined geologically as the limits of the geologic...

As part of a broader research program to examine domestic source rock reservoirs, the Gulf Coast Petroleum Systems project of the USGS Energy Resources Program drilled a research borehole into Late Cretaceous mudstones in McLennan County, Texas, including the Cenomanian-Turonian Eagle Ford Group. A comprehensive wireline geophysical logging suite and over 600 ft of continuous core were obtained to advance the understanding of the stratigraphy, rock and fluid properties, burial history, and depositional environment of these uncompacted and thermally immature Eagle Ford source rocks. Geophysical logs were calibrated with geochemical core data to characterize mineralogical variability and petrophysical characterization...
