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.

Natural bitumen and extra-heavy oil Natural bitumen and extra-heavy oil
Since 2005, oil price increases have greatly increased investment in the production of extra- heavy oil and natural bitumen (tar sands or oil sands) to supplement conventional oil supplies. These oils are characterised by their high viscosity, high density (low API gravity), and high concentrations of nitrogen, oxygen, sulphur, and heavy metals. Extra-heavy oil and natural bitumen are...

A Program for Partitioning Shifted Truncated Lognormal Distributions into Size-Class Bins A Program for Partitioning Shifted Truncated Lognormal Distributions into Size-Class Bins
In recent years, oil and gas accumulation-size frequency distributions have become a standard way to characterize undiscovered conventional oil and gas resources that have been postulated by geologic assessments. The preparation of such distributions requires the assessment geologists to explicitly choose parameters for the probability distribution for the sizes of undiscovered...

Heavy oil and natural bitumen resources in geological basins of the world Heavy 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...

Statistics of petroleum exploration in the world outside the United States and Canada through 2001 Statistics of petroleum exploration in the world outside the United States and Canada through 2001
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. It updates U.S. Geological Survey Circular 1096 (by E.D. Attanasi and D.H. Root, 1993...

Economic decision making and the application of nonparametric prediction models Economic 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 large. Planning and development decisions for extraction of such resources...

Prediction of resource volumes at untested locations using simple local prediction models Prediction of resource volumes at untested locations using simple local prediction models
This paper shows how local spatial nonparametric prediction models can be applied to estimate volumes of recoverable gas resources at individual undrilled sites, at multiple sites on a regional scale, and to compute confidence bounds for regional volumes based on the distribution of those estimates. An approach that combines cross-validation, the jackknife, and bootstrap procedures is...

Discovery sequence and the nature of low permeability gas accumulations Discovery sequence and the nature of low permeability gas accumulations
There is an ongoing discussion regarding the geologic nature of accumulations that host gas in low-permeability sandstone environments. This note examines the discovery sequence of the accumulations in low permeability sandstone plays that were classified as continuous-type by the U.S. Geological Survey for the 1995 National Oil and Gas Assessment. It compares the statistical character...
