The objective of this research task is to conduct a national assessment of recoverable oil related to CO2 injection. The amount of CO2 stored (utilized) during the hydrocarbon recovery process will also be evaluated.
A description of the "Comprehensive Resource Database” (CRD) and the computer algorithms used
The USGS has developed a new methodology for the national assessment of technically recoverable oil resources that may be produced by using current CO2-EOR technologies.
Utilization of CO2 for enhanced oil recovery (EOR) in existing or depleted hydrocarbon reservoirs can increase the U.S. hydrocarbon recoverable resource volume and prevent wasteful CO2 release to the atmosphere.
The Energy Independence and Security Act (EISA, Public Law 110-140) of 2007 authorized the USGS to conduct a national assessment of geologic storage resources and to evaluate the national technically recoverable hydrocarbon resources resulting from CO2 injection and related storage (CO2-EOR).
The USGS recently completed the national CO2 storage assessment (see U.S. Geological Survey Geologic Carbon Dioxide Storage Resources Assessment Team, 2013); however, an evaluation of recoverable hydrocarbons (oil) related to CO2 injection was delayed to allow the USGS time to build a comprehensive CO2-EOR database and to develop an assessment methodology to evaluate the recovery potential for oil related to CO2 injection.
The USGS CO2-EOR assessment will build upon previous technical/economic evaluations conducted by industry, government, and academic organizations; however, the USGS assessment will be of the total technically recoverable oil resources, and will not include a minimum economic cutoff.
Previous assessments of CO2-EOR recoverable resources have included economic constraints and vary widely with some estimates of over 100 billion barrels of technically recoverable oil. The national resource of technically recoverable oil resulting from CO2 injection on a non-economic basis is unknown.

Atmospheric carbon dioxide comes from two primary sources—natural and human activities. Natural sources of carbon dioxide include most animals, which exhale carbon dioxide as a waste product. Human activities that lead to carbon dioxide emissions come primarily from energy production, including burning coal, oil, or natural gas.Learn more: Sources of Greenhouse Gas Emissions (EPA)
The USGS is congressionally mandated (2007 Energy Independence and Security Act) to conduct a comprehensive national assessment of storage and flux (flow) of carbon and the fluxes of other greenhouse gases (including carbon dioxide) in ecosystems.At this writing, reports have been completed for Alaska, the Eastern U.S., the Great Plains, and the Western U.S.Learn more: LandCarbon
The U.S. Energy Information Administration estimates that in 2019, the United States emitted 5.1 billion metric tons of energy-related carbon dioxide, while the global emissions of energy-related carbon dioxide totaled 33.1 billion metric tons.
It is difficult to characterize one area as “the best” for carbon sequestration because the answer depends on the question: best for what? However, the area of the assessment with the most storage potential for carbon dioxide is the Coastal Plains region, which includes coastal basins from Texas to Georgia. That region accounts for 2,000 metric gigatons, or 65 percent, of the storage potential...
In 2013, the USGS released the first-ever comprehensive, nation-wide assessment of geologic carbon sequestration, which estimates a mean storage potential of 3,000 metric gigatons of carbon dioxide. The assessment is the first geologically-based, probabilistic assessment, with a range of 2,400 to 3,700 metric gigatons of potential carbon dioxide storage. In addition, the assessment is for the...
Geologic carbon sequestration is the process of storing carbon dioxide (CO2) in underground geologic formations. The CO2 is usually pressurized until it becomes a liquid, and then it is injected into porous rock formations in geologic basins. This method of carbon storage is also sometimes a part of enhanced oil recovery, otherwise known as tertiary recovery, because it is typically used later in...
Carbon dioxide is the most commonly produced greenhouse gas. Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide. It is one method of reducing the amount of carbon dioxide in the atmosphere with the goal of reducing global climate change. The USGS is conducting assessments on two major types of carbon sequestration: geologic and biologic.
