The U.S. Geological Survey has evaluated three methods for estimating how much oil and gas could be produced by injecting carbon dioxide (CO2) into petroleum reservoirs.

Carbon capture from stationary sources and geologic storage of carbon dioxide (CO2) is an important option to include in strategies to mitigate greenhouse gas emissions. However, the potential costs of commercial-scale CO2 storage are not well constrained, stemming from the inherent uncertainty in storage resource estimates coupled with a lack of detailed estimates of the infrastructure needed to...

Current estimates of discovered viscous and heavy oil in Alaska’s North Slope are 12 billion barrels of oil-in-place and 12–18 billion barrels of oil-in-place, respectively (see Appendix 1 for conversion to SI units). Since the early 1990s to the end of 2010, cumulative viscous oil production has amounted to 150 million barrels, and there has been no commercial production of heavy oil...

Outside PublicationThis study deﬁnes stranded conventional gas resources as gas in identiﬁed (discovered and appraised) conventional oil and gas accumulations which are not currently commercially producible for either physical or economic reasons. The discovered conventional North Slope gas is stranded because there is currently no transportation system to take the gas to a market.
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.
The U.S. Geological Survey prepares geologic assessments of undiscovered and undeveloped (identified) oil and gas resources (see National Oil and Gas Assessment website). In addition to our USGS oil and gas geologic assessments, economic research gives policymakers and analysts in the private sector additional information by scaling economic variables. Economic attributes must include the costs of finding, developing, and producing undiscovered and undeveloped resources for both conventional and unconventional oil and gas occurrences. This research activity provides for the economic analysis of selected USGS energy resource geologic assessments so that government policymakers and industry decision makers have information on what part of the resource is commercial and, if currently produced, how long production can be sustained. Another thrust of this ongoing research is to propose enhancements in assessment methods that would permit more transparency in the economic analysis of the assessed resource.
During the last decade many producing countries have reassigned conventional oil and gas development rights to their national oil companies (NOCs). In fact the 13 largest energy companies, when measured by oil and gas reserves, are controlled by sovereign governments. The result is that the NOC’s will control a significant share of future oil and gas production. The international oil companies (IOCs) are relegated to minority project partners, contractors, or to marginally economic hydrocarbon resources. These latter resources may require special extraction technologies because of location, environment, or because they are unconventional. The largest part of the remaining hydrocarbon resource base is associated with unconventional oil and gas resources. These resources include stranded gas, heavy oil, and natural bitumen; resources that historically did not enter established markets because of quality, location, or extraction technology. The resource volumes that make up these massive accumulations must be scaled by economic variables for energy policy analysts and industry decision makers to predict when these resources will enter international oil and gas supplies. Research focuses on development of theoretically sound methods to value these marginal resources and to characterize the commercial and social costs of their development.
