A Methodology to Assess the National and Regional Impacts of U.S. Wind Energy Development on Birds and Bats
This scientific investigations report describes an effort by the U.S. Geological Survey (USGS) that used research, monitoring data, and modeling to develop a methodology to assess both the current and future population-level consequences of wind energy development on species of birds and bats that are present in the United States during any part of their life cycle. The methodology is currently ap

Improving pressure-limited CO2 storage capacity in saline formations by means of brine extraction
The carbon dioxide (CO2) storage capacity of saline formations may be constrained by reservoir pressure limitations. Brine extraction could be necessary to increase the CO2 storage capacity of a given formation, manage the extent of the underground CO2 plume and induced pressure front, and control the migration direction. To estimate the additional CO2 storage capacity of a saline formation that c

Assessment of shale-oil resources of the Sirte Basin Province, Libya, 2019
Using a geology-based assessment methodology, the U.S. Geological Survey estimated undiscovered, technically recoverable mean resources of 23.7 billion barrels of shale oil and 23 trillion cubic feet of associated gas in the onshore part of the Sirte Basin Province of Libya.

Assessment of undiscovered oil and gas resources of the Sirte and Pelagian Basin Provinces of Libya, Tunisia, Malta, and Italy, 2019
Using a geology-based assessment methodology, the U.S. Geological Survey estimated undiscovered, technically recoverable mean resources of 16.4 billion barrels of oil and 106.3 trillion cubic feet of gas in the Sirte and Pelagian Basin Provinces of Libya, Tunisia, Malta, and Italy.

Statistics of petroleum exploration in the world outside the United States and Canada through 2015
The world’s future oil and gas supplies depend on existing reserves and the additions to those reserves that may result, in part, from ongoing exploration and new discoveries. This Circular summarizes available oil and gas exploration data for the world outside the United States and Canada (the study area) through 2015. It updates U.S. Geological Survey Circulars 981, 1096, and 1288 (by D.H. Root,

Estimating the pressure-limited dynamic capacity and costs of basin-scale CO2 storage in a Saline Formation
Deployment of carbon capture and storage (CCS) could be necessary to be able to satisfy baseload electricity demand, maintain diversity in the energy mix, and achieve mitigation of carbon dioxide (CO2) emissions at lowest cost (IPCC, 2015; U.S. DOE, 2016). If basin-, regional- or national-scale deployment of CCS is needed, it may be possible to store only a small fraction of the captured CO2 in oi

Quantitative evaluation of vitrinite reflectance in shale using Raman spectroscopy and multivariate analysis
The current research builds upon a previously published study that demonstrated the combination of Raman spectroscopy coupled with multivariate analysis (MVA) for the prediction of thermal maturity in coal by evaluating the efficacy of this method for the prediction of thermal maturity in shale. MVA techniques eliminate analyst bias in peak-fitting methods by using the full Raman spectrum, and the

Assessment of tight-oil and tight-gas resources in the Junggar and Santanghu Basins of Northwestern China, 2018
Using a geology-based assessment methodology, the U.S. Geological Survey estimated undiscovered, technically recoverable mean resources of 241 million barrels of tight oil and 10.1 trillion cubic feet of tight gas in the Junggar and Santanghu Basins of northwestern China.

An ANCOVA model for porosity and its uncertainty for oil reservoirs based on TORIS dataset
Porosity is one of the most important parameters to assess in-place oil or gas in reservoirs, and to evaluate recovery from enhanced production operations. Since it is relatively well-established to determine porosity using different laboratory and field methods, its value is usually determined at many locations across a reservoir as part of the common practice to capture reservoir heterogeneity a

Application of electron microscopy TEM and SEM for analysis of coals, organic-rich shales and carbonaceous matter
This paper provides a brief summary of the history, development and variety of applications of electron microscopy
techniques to analyze coals, organic-rich shales, and carbonaceous materials. General construction and principles of
operation of transmitted (TEM) and scanning electron microscope (SEM) are outlined, along with guidance on
specimen preparation, and a brief overview of published TEM a

Assessment of coal mine methane (CMM) and abandoned mine methane (AMM) resource potential of longwall mine panels: example from Northern Appalachian Basin, USA
"Coal mine methane (CMM) and abandoned mine methane (AMM), are by-products of underground coal mining. The quantity and the emission rate of CMM and AMM may vary depending on the type of mine, gas content of the mined coal seam, and gas sourced from strata and coal beds in overlying and underlying formations affected by mining. Therefore, if a mine has the potential of accumulating gas after being

Insights from Rock-Eval analysis on the influence of sample weight on hydrocarbon generation from Lower Permian organic-matter rich rocks, West Bokaro basin, India
Among the different Rock-Eval parameters, the hydrocarbons released under S2 peak of Rock-Eval is of significance as it indicates the residual hydrocarbon content of the rock. Further, through its relationship with TOC content, it helps in calculating hydrogen indices (HI) which helps in understanding the type of organic-matter present in a rock [HI= (S2/TOC)*100]. The present study documents the
