Philip Freeman is an Operations Research Analyst with the USGS Geology, Energy & Minerals (GEM) Science Center in Reston, VA.
Philip obtained his B.S. in Engineering at Cornell University in 1986. He is an Operations Research Analyst at the Eastern Energy Resources Science Center in Reston, Virginia. His experience in resource assessment work spans oil and gas, coal, reserve growth, and carbon dioxide storage resources. He has worked on teams tasked to develop probabilistic resource assessment methodologies. His contributions to economic analysis includes developing business development models, constructing geographic analysis and estimating annual production functions. He has experience combining large datasets of well, reservoir and field data for physical characterization of rock and/or fluid properties and using GIS for analysis or presentation.

Empirical methods for detecting regional trends and other spatial expressions in antrim shale gas productivity, with implications for improving resource projections using local nonparametric estimation techniques
The primary objectives of this research were to (1) investigate empirical methods for establishing regional trends in unconventional gas resources as exhibited by historical production data and (2) determine whether or not incorporating additional knowledge of a regional trend in a suite of previously established local nonparametric resource prediction algorithms influences assessment results. ThrAuthorsTimothy C. Coburn, Philip A. Freeman, Emil D. AttanasiNew U.S. Geological Survey method for the assessment of reserve growth
Reserve growth is defined as the estimated increases in quantities of crude oil, natural gas, and natural gas liquids that have the potential to be added to remaining reserves in discovered accumulations through extension, revision, improved recovery efficiency, and additions of new pools or reservoirs. A new U.S. Geological Survey method was developed to assess the reserve-growth potential of tecAuthorsTimothy R. Klett, Emil D. Attanasi, Ronald R. Charpentier, Troy A. Cook, Philip A.

Two important trends affecting the expected growth of global gas markets are (1) the shift by many industrialized countries from coal-fired electricity generation to the use of natural gas to generate electricity and (2) the industrialization of the heavily populated Asian countries of India and China. This paper surveys discovered gas in stranded conventional gas accumulations and presents estimaAuthorsEmil D. Attanasi, Philip A. FreemanA probabilistic assessment methodology for the evaluation of geologic carbon dioxide storage
In 2007, the Energy Independence and Security Act (Public Law 110-140) authorized the U.S. Geological Survey (USGS) to conduct a national assessment of potential geologic storage resources for carbon dioxide (CO2) in cooperation with the U.S. Environmental Protection Agency and the U.S. Department of Energy. The first year of that activity was specified for development of a methodology to estimateAuthorsSean T. Brennan, Robert A. Burruss, Matthew D. Merrill, Philip A. Freeman, Leslie F. RuppertEconomics of undiscovered oil and gas in the North Slope of Alaska: Economic update and synthesis
The U.S. Geological Survey (USGS) has published assessments by geologists of undiscovered conventional oil and gas accumulations in the North Slope of Alaska; these assessments contain a set of scientifically based estimates of undiscovered, technically recoverable quantities of oil and gas in discrete oil and gas accumulations that can be produced with conventional recovery technology. The assessAuthorsEmil D. Attanasi, Philip A. FreemanDevelopment of a probabilistic assessment methodology for evaluation of carbon dioxide storage
This report describes a probabilistic assessment methodology developed by the U.S. Geological Survey (USGS) for evaluation of the resource potential for storage of carbon dioxide (CO2) in the subsurface of the United States as authorized by the Energy Independence and Security Act (Public Law 110-140, 2007).

SchenkExploration maturity key to ranking search areas
The study area of US Geological Survey Circular 1288, the world outside the US and Canada, was partitioned into 44 countries and country groups. Map figures such as Fig. 2 and graphs similar to Figs. 3 and 4 provide a visual summary of maturity of oil and gas exploration. From 1992 through 2001, exploration data show that in the study area the delineated prospective area expanded at a rate of abouAuthorsEmil D. Attanasi, Philip A. FreemanEconomic decision making and the application of nonparametric prediction models
Sustained increases in energy prices have focused attention on gas resources in low-permeability shale or in coals that were previously considered economically marginal. Daily well deliverability is often relatively small, although the estimates of the total volumes of recoverable resources in these settings are often large. Planning and development decisions for extraction of such resources mustAuthorsEmil D. Attanasi, Timothy C. Coburn, Philip A. FreemanHeavy oil and natural bitumen resources in geological basins of the world
Heavy oil and natural bitumen are oils set apart by their high viscosity (resistance to flow) and high density (low API gravity). These attributes reflect the invariable presence of up to 50 weight percent asphaltenes, very high molecular weight hydrocarbon molecules incorporating many heteroatoms in their lattices. Almost all heavy oil and natural bitumen are alteration products of conventional oAuthorsRichard F. Meyer, Emil D. Attanasi, Philip A.

Future oil and gas supplies depend, in part, on the reserves that are expected to be added through exploration and new discoveries. This Circular presents a summary of the statistics and an analysis of petroleum exploration in the world outside the United States and Canada (the study area) through 2001.
