Emil D. Attanasi, Ph.D.
Emil Attanasi is a Supervisory Research Economist (Scientist Emeritus) with the USGS Geology, Energy & Minerals (GEM) Science Center in Reston, VA.
Emil Attanasi has been an economist with the U.S. Geological Survey since 1972. His work focuses on the valuation of hydrologic data, development of resource assessment methods for undiscovered oil and gas, assessment of CO2-EOR potential, and the application of economics to oil, gas, and minerals resource assessments.

Growth drivers of Bakken oil well productivity 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 conditions. The temporal component of well

Statistics of petroleum exploration in the world outside the United States and Canada through 2015 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...

Carbon dioxide enhanced oil recovery and residual oil zone studies at the U.S. Geological Survey 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 retention of CO2 in reservoir pore space...

Statistical detection of flow regime changes in horizontal hydraulically fractured Bakken oil wells Statistical detection of flow regime changes in horizontal hydraulically fractured Bakken oil wells
The application of horizontal and hydraulically fractured wells for producing oil from low permeability formations has changed the face of the North American oil industry. One feature of the production profile of many such wells is a transition from transient linear oil flow to boundary-dominated flow. The identification of the time of this transition is important for the calibration of...

Overview of a comprehensive resource database for the assessment of recoverable hydrocarbons produced by carbon dioxide enhanced oil recovery 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 contract to the USGS. The CRD contains...

Using CO2 Prophet to estimate recovery factors for carbon dioxide enhanced oil recovery Using CO2 Prophet to estimate recovery factors for carbon dioxide enhanced oil recovery
Introduction The Oil and Gas Journal’s enhanced oil recovery (EOR) survey for 2014 (Koottungal, 2014) showed that gas injection is the most frequently applied method of EOR in the United States and that carbon dioxide (CO2 ) is the most commonly used injection fluid for miscible operations. The CO2-EOR process typically follows primary and secondary (waterflood) phases of oil reservoir...
