Dr. Eric Robertson provides a retrospective analysis of the Enhanced Oil Recovery Institute’s (EORI) collaborative work in Wyoming since 2004, focusing on CO₂ enhanced oil recovery projects within the state.

CO₂ - EOR technology has been instrumental in producing significant volumes of oil from four key fields: Beaver Creek, Big Sand Draw, Grieve, and Salt Creek. The analysis of each field is accompanied by charts that illustrate the dramatic benefits of CO₂ - EOR technology.

As of April 2024, 67 million barrels of incremental oil have been produced from these fields, providing $558 million in tax revenue to the state, and will continue to grow as these CO₂ - EOR fields continue to produce.

Advanced Resources International has published the U.S. CO2 Enhanced Oil Recovery Survey for end-of-year 2020.

The Enhanced Oil Recovery Institute’s Acting Director, Lon Whitman, is a contributor to an important and anticipated publication of the U.S. CO2 Enhanced Oil Recovery Survey.

The purpose of this updated survey is to provide a comprehensive status report of the 142 active CO2-EOR projects in the U.S., including enhanced production totals, reservoir characteristics, and other project parameters.

Throughout a challenging year, incremental oil production from CO2-EOR declined about 8% to 273,000 barrels per day -- this total is on par with the overall decline in U.S. crude oil production in 2020.

Despite a significant decrease in the volumes of CO2 available for injection and storage the CO2-EOR industry was able to maintain production by recycling CO2 rather than having to shut in wells. This strategy shows the resiliency of CO2-EOR during challenging economic conditions, and further supports the viability of this method as a means of storing CO2 and producing lower carbon intensity oil in the U.S.

The purpose of this survey is to provide a comprehensive status report of active CO2 EOR projects in the U.S., as of end-of-year 2019. This survey provides the first update of CO2 EOR project data since the final publication of the Oil & Gas Journal (OGJ) EOR Survey in 2014.

The 2019 U.S CO2 EOR survey shows that incremental oil recovery from CO2 EOR in the U.S. has held steady at approximately 300,000 barrels of oil per day. A total of 3.0 Bcf per day of CO2 is purchased for CO2 EOR, including 1.0 Bcf per day from “industrial” sources, which represents an increase of 30% over the last seven years.

Carbon management, in the form of CO2 capture and storage, is the most viable pathway to meeting significant carbon emission reduction targets over the next several decades. This survey demonstrates the value and potential of CO2 EOR to the overall carbon management strategy in the U.S.

Periodic updates will be made to this survey to include the latest CO2 EOR project data available. This publication is intended as a public resource for petroleum and energy industry stakeholders, and is offered free of charge by ARI. The next survey update is anticipated for Fall 2021.

The Great Plains Institute (GPI) and the University of Wyoming’s Jeffrey Brown explore the planning of CO₂ transportation networks on a regional scale and ascertains the economic and environmental benefits that can be achieved through economies of scale to meet the US midcentury decarbonization goals.

This paper represents the results of modeling efforts to identifying regional scale CO₂ transport infrastructure that would serve existing facilities and allow participation by new capture projects and facilities in the near future.
