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.

Resource constraints in petroleum production potential Resource constraints in petroleum production potential
Geologic reasons indicate that the dominant position of the Middle East as a source of conventional petroleum will not be changed by new discoveries elsewhere. The share of world crude oil production coming from the Middle East could increase, within 10 to 20 years, to exceed 50 percent, under even modest increases in world consumption. Nonconventional resources of oil exist in large...

Alternative natural gas contract and pricing structures and incentives of the LNG industry Alternative natural gas contract and pricing structures and incentives of the LNG industry
Gas conversion to liquefied gas (LNG) and transport by LNG tankers is one option for meeting expanding gas consumption and for gas traded internationally. This paper examines the impact of the traditional gas contract provisions of indefinite pricing, market out price ceilings, and take‐or‐pay requirements on the profitability of LNG projects in the context of markets characterized by...

Economic implications of petroleum field size distributions Economic implications of petroleum field size distributions
The unprecedented natural gas price increases in the late 1970's and early 1980's allowed a glimpse of part of the in-situ distribution of natural gas fields that had been hidden by economic truncation. Analysis of those discoveries shows the distribution to be characterized by progressively larger numbers of fields as size category declines. This paper demonstrates the effects of...

Robustness of disaggregate oil and gas discovery forecasting models Robustness of disaggregate oil and gas discovery forecasting models
The trend in forecasting oil and gas discoveries has been to develop and use models that allow forecasts of the size distribution of future discoveries. From such forecasts, exploration and development costs can more readily be computed. Two classes of these forecasting models are the Arps-Roberts type models and the 'creaming method' models. This paper examines the robustness of the...

Observed oil and gas field size distributions: A consequence of the discovery process and prices of oil and gas Observed oil and gas field size distributions: A consequence of the discovery process and prices of oil and gas
If observed oil and gas field size distributions are obtained by random samplings, the fitted distributions should approximate that of the parent population of oil and gas fields. However, empirical evidence strongly suggests that larger fields tend to be discovered earlier in the discovery process than they would be by random sampling. Economic factors also can limit the number of small...

Forecasting petroleum discoveries in sparsely drilled areas: Nigeria and the North Sea Forecasting petroleum discoveries in sparsely drilled areas: Nigeria and the North Sea
Decline function methods for projecting future discoveries generally capture the crowding effects of wildcat wells on the discovery rate. However, these methods do not accommodate easily situations where exploration areas and horizons are expanding. In this paper, a method is presented that uses a mapping algorithm for separating these often countervailing influences. The method is...

Physical deposit measures and commercial potential: The case of titanium-bearing heavy-mineral deposits Physical deposit measures and commercial potential: The case of titanium-bearing heavy-mineral deposits
Physical measures of mineral deposit characteristics, such as grade and tonnage, long have been used in both subjective and analytic models to predict favorability of areas for the occurrence of mineral deposits of particular types. After a deposit has been identified, however, the explorationist must decide whether to continue data collection, begin an economic feasibility study, or...
