Science and Products
Economics of Energy Transitions
This task conducts research to characterize or evaluate the economics of developing technologies or markets in geologic resources. Such research can analyze the relative risks, costs, and benefits from the utilization and not just the extraction of underground resource. Economic analysis builds upon the geologic resource assessment work by other tasks in the Utilization of Carbon and other...
Economics, Energy Resources, and Future Energy Supply
The members of this project have prepared a number of analyses that constitute the economic components of energy resource assessments. They have also proposed enhancements to geologic assessment data and methods that make results of assessments immediately amenable to economic analysis. In addition, they apply theoretically sound valuation methodologies to assess the commercial value of...
Economics of Global Marginal Hydrocarbon and Non-traditional Resources
During the last decade many producing countries have reassigned conventional oil and gas development rights to their national oil companies (NOCs). In fact the 13 largest energy companies, when measured by oil and gas reserves, are controlled by sovereign governments. The result is that the NOC’s will control a significant share of future oil and gas production. The international oil companies...
Economics of U.S. Oil and Gas Resources
The U.S. Geological Survey prepares geologic assessments of undiscovered and undeveloped (identified) oil and gas resources (see National Oil and Gas Assessment website). In addition to our USGS oil and gas geologic assessments, economic research gives policymakers and analysts in the private sector additional information by scaling economic variables. Economic attributes must include the...
Machine learning can assign geologic basin to produced water samples using major ion geochemistry
Understanding the geochemistry of waters produced during petroleum extraction is essential to informing the best treatment and reuse options, which can potentially be optimized for a given geologic basin. Here, we used the US Geological Survey’s National Produced Waters Geochemical Database (PWGD) to determine if major ion chemistry could be used...
Shelton, Jenna L.; Jubb, Aaron M.; Saxe, Samuel; Attanasi, Emil D.; Milkov, Alexei; Engle, Mark A; Freeman, Philip A.; Shaffer, Christopher; Blondes, Madalyn S. Comparison of machine learning approaches used to identify the drivers of Bakken oil well productivity
Geologists and petroleum engineers have struggled to identify the mechanisms that drive productivity in horizontal hydraulically fractured oil wells. The machine learning algorithms of Random Forest (RF), gradient boosting trees (GBT) and extreme gradient boosting (XGBoost) were applied to a dataset containing 7311 horizontal hydraulically...
Attanasi, Emil D.; Freeman, Philip A.; Coburn, Timothy Well predictive performance of play-wide and Subarea Random Forest models for Bakken productivity
In recent years, geologists and petroleum engineers have struggled to clearly identify the mechanisms that drive productivity in horizontal, hydraulically-fractured oil wells producing from the middle member of the Bakken formation. This paper fills a gap in the literature by showing how this play’s heterogeneity affects factors that drive well...
Attanasi, Emil D.; Freeman, Philip A.; Coburn, Tim Methodology for estimating the prospective CO2 storage resource of residual oil zones at the national and regional scale
Residual oil zones (ROZs) are increasingly gaining interest as potential reservoirs for carbon dioxide (CO2) storage. Here, we present a national- and regional-scale methodology for estimating prospective CO2 storage resources in residual oil zones. This methodology uses a volumetric equation that accounts for CO2 storage as a free phase...

A probabilistic assessment methodology for carbon dioxide enhanced oil recovery and associated carbon dioxide retention
The U.S. Energy Independence and Security Act of 2007 authorized the U.S. Geological Survey (USGS) to conduct a national assessment of the potential volume of hydrocarbons recoverable by injection of carbon dioxide (CO2) into known oil reservoirs with historical production. The implementation of CO2 enhanced oil recovery (CO2-EOR) techniques could...

Özgen; Shelton, Jenna L.; Lohr, Celeste D.; Jahediesfanjani, Hossein; Roueché, Jacqueline N. Growth drivers of Bakken oil well productivity
This paper identifies the drivers of the phenomenal growth in productivity in hydraulically fractured horizontal oil wells producing from the middle member of the Bakken Formation in North Dakota. The data show a strong underlying spatial component and somewhat weaker temporal component. Drivers of the spatial component are favorable reservoir...

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...
Attanasi, Emil D.; Freeman, Philip A. Carbon dioxide enhanced oil recovery and residual oil zone studies at the U.S. Geological Survey
The U.S. Geological Survey (USGS) is preparing a national resource assessment of the potential hydrocarbons recoverable after injection of carbon dioxide (CO2) into conventional oil reservoirs in the United States. The implementation of CO2-enhanced oil recovery (CO2-EOR) techniques can increase hydrocarbon production, and lead to incidental...

Federal lands greenhouse emissions and sequestration in the United States—Estimates for 2005–14
In January 2016, the Secretary of the U.S. Department of the Interior tasked the U.S. Geological Survey (USGS) with producing a publicly available and annually updated database of estimated greenhouse gas emissions associated with the extraction and use (predominantly some form of combustion) of fossil fuels from Federal lands. In response, the...

Overview of a comprehensive resource database for the assessment of recoverable hydrocarbons produced by carbon dioxide enhanced oil recovery
A database called the “Comprehensive Resource Database” (CRD) was prepared to support U.S. Geological Survey (USGS) assessments of technically recoverable hydrocarbons that might result from the injection of miscible or immiscible carbon dioxide (CO2) for enhanced oil recovery (EOR). The CRD was designed by INTEK Inc., a consulting company under...
