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 currently marginal oil and gas resources, such as heavy oil, natural bitumen, stranded gas, and resources in high cost environments.
Economic components of undiscovered oil and gas assessments present estimates of the cost of finding, developing, producing, and transporting to market the undiscovered resources assessed by the USGS geologists:
- The enhancement of assessment data and methods to include an economic dimension will lead to improved strategic decisions by public policymakers concerning national and international energy resources.
- Economic assessment of marginal oil resources includes the formulation and estimation of cost functions to extract heavy oil and bitumen in known deposits and to transform those resources to high value transportation fuels
- Economic assessment of stranded gas provides estimates of the cost of developing, producing, and transporting to market remote natural gas in known fields

Filter Total Items: 57A 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 accumulations. TheHeavy 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 oEconomic 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 must be areSiberian platform: Geology and natural bitumen resources
The Siberian platform is located between the Yenisey River on the west and the Lena River on the south and east. The Siberian platform is vast in size and inhospitable in its climate. This report is concerned principally with the setting, formation, and potential volumes of natural bitumen. In this report the volumes of maltha and asphalt referred to in the Russian literature are combined to repreEconomics of undiscovered oil and gas in the central North Slope, Alaska

No abstract available.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 used to accoDiscovery 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 of historicA bootstrap approach to computing uncertainty in inferred oil and gas reserve estimates
This study develops confidence intervals for estimates of inferred oil and gas reserves based on bootstrap procedures. Inferred reserves are expected additions to proved reserves in previously discovered conventional oil and gas fields. Estimates of inferred reserves accounted for 65% of the total oil and 34% of the total gas assessed in the U.S. Geological Survey’s 1995 National Assessment of oil - News
