Coalbed Natural Gas Exploration, Drilling Activities, and Geologic Test Results

2007–2010, in Wainwright, Alaska

USGS Publication: Open-File Report 2014–1004
The U.S. Geological Survey, in partnership with the U.S. Bureau of Land Management, the North Slope Borough, and the Arctic Slope Regional Corporation conducted a four-year study designed to identify, define, and delineate a shallow coalbed natural gas (CBNG) resource with the potential to provide locally produced, affordable power to the community of Wainwright, Alaska.

Characterization of the Marcellus Shale Based on Computer-Assisted Correlation of Wireline Logs in Virginia and West Virginia

USGS Publication: Scientific Investigations Report 2013–5131
In an attempt to determine if this scale of deformation is detectable with conventional wireline logs, petrophysical properties (primarily mineralogy and porosity) were measured by interpretation of gamma-ray and bulk-density logs. The results of performing a statistical correlation of wireline logs from nine wells indicated that there are discontinuities within the Millboro Shale (undifferentiated Marcellus Shale and Mahantango Formation) where there are significant thickness differences between wells.

Marine Methane Hydrate Field Research Plan

Field Report
In 2013, the U.S. Department of Energy’s (DOE) National Energy Technology Laboratory (NETL), in partnership with the Consortium for Ocean Leadership (COL), initiated a new field-focused methane hydrate research planning effort that would inform, and potentially lead to, future off shore drilling field expeditions.

A Framework for Assessing Water and Proppant Use and Flowback Water Extraction Associated with Development of Continuous Petroleum Resources

USGS Publication: Fact Sheet 2014–3010
This fact sheet provides an overview of U.S. Geological Survey assessments for quantities of water and proppant required for drilling and hydraulic fracturing and for flowback water extracted with petroleum; the report also presents the form of the intended assessment output information.

Detailed Cross Sections of the Eocene Green River Formation

USGS Publication: Scientific Investigations Map 3276
This report presents two detailed cross sections of the Eocene Green River Formation in the Piceance Basin, northwestern Colorado, constructed from eight detailed measured sections, fourteen core holes, and two rotary holes. The cross sections extend across the northern and eastern margins of the Piceance Basin and are intended to aid in correlating between surface sections and the subsurface in the basin.

Linking Compositional Data Analysis with Thermodynamic Geochemical Modeling

Oilfield Brines from the Permian Basin, USA

Outside Publication: Journal of Geochemical Exploration
Compositional data analysis (CoDa) of sedimentary basin brines can help reveal the hydrogeochemical history of hydrocarbon producing formations. This paper demonstrates the novel approach of pairing CoDa with thermodynamic geochemical models for bivariate and multivariate subcompositions for a suite of brines within three producing formations from the Permian Basin, USA.
