Partnership established to research underground CO2 storage

Aug 16 2020


The Carbon Utilization and Storage Partnership, or CUSP, is led by the Petroleum Recovery Research Center (PRRC) at the New Mexico Institute of Mining and Technology, which was awarded $6.24 million by the U.S. Department of Energy (DOE) for the project.

For two decades, the Kansas Geological Survey has been investigating the state's subsurface geology and industrial infrastructure to determine the safety and viability of injecting carbon dioxide (CO2) from industrial sources into underground rock formations for long-term storage and to recover hard-to-reach oil. As part of an initiative to share data and advance research on the process, the KGS is now partnering with 15 other state and federal entities from throughout the central and western United States.

The KGS will receive about $310,000 of the funding and could get additional funding for database development and other purposes as the project progresses through 2024.

"Nationwide, CCUS is moving ahead. There are multiple large-scale commercial project announcements and the portfolio is growing," said Eugene Holubnyak, petroleum engineer and the project's lead investigator at the KGS. "KGS has developed a very strong CCUS program on its own and this time around we want to play a central and integral role in CUSP."

During the CCUS process, CO2 emitted by an industrial source is captured and transported through pipelines to a location where it can be used to squeeze out trapped oil unreachable by traditional recovery methods or stored long-term in deep and confined underground rock formations.

The Osage, Viola, and Arbuckle Groups, porous rock formations that contain extremely saline water separated from shallower, freshwater aquifers by thousands of feet of impermeable rock, are the key targets for CO2 storage in western Kansas. Pore space in subsurface rock units has been used for more than a century for disposal of waste fluids produced through industrial processes, petroleum production, municipal water treatment, and other operations.

Over the past 10 years, the KGS has led or played a key role in five large-scale CCUS projects funded by DOE. Working with private partners, the KGS has successfully injected CO2 for Enhanced Oil Recovery in the Wellington Field in Sumner County south of Wichita and the Hall-Gurney Field in Russell County. During previous and ongoing projects, the KGS has amassed large quantities of seismic data, drilling data and rock cuttings, and drill cores - cylindrical segments of rock brought up intact from thousands of feet underground.

The KGS team is participating in all five CUSP focus areas - data management, data analysis, policy and law, economics, and outreach

"Currently, the KGS team is selecting database architecture to create an interactive, open-access dataset that will include subsurface, infrastructure, industrial, and other data," said Franek Hasiuk, KGS geologist and co-principal investigator at the KGS on the project. "It will include information from all CUSP member states, and possibly beyond, that will be very useful for CCUS projects, the oil and gas industry, regulators, and other stakeholders."

Interest in capturing and storing carbon emissions was regenerated in 2018 when the Internal Revenue Service updated a tax incentive, known as 45Q, for companies willing to capture and store CO2. Oil and gas production, ethanol, electrical-power generation, pipeline, agriculture, and other industries are eligible.

For long-term storage, CO2 is injected into UIC Class VI wells. The Safe Drinking Water Act, passed by Congress in 1974, established the requirements for the Underground Injection Control (UIC) program, which consists of six classes of wells designated for underground disposal of different levels of non-hazardous and hazardous waste.

"The KGS is helping well operators prepare sites to qualify for 45Q credits and apply for UIC Class VI permits", Holubnyak said. "We are working with developers to screen geologic sites for potential commercial projects."

The KGS also is working with the Los Alamos National Laboratories and other CUSP members on methods to analyze data that will provide a better understanding of local and regional infrastructure development potential, infrastructure costs, and ways to optimize future project development.

In addition to the PRRC at New Mexico Institute of Mining and Technology and the KGS, the CUSP partners are the University of Utah, University of Texas Permian Basin, Arizona Geological Survey, Colorado School of Mines, Stanford University, Desert Research Institute of Nevada, Montana State University, Oklahoma Geological Survey, Washington Geological Survey, the University of Oklahoma, Indiana University, Utah Geological Survey, and the Pacific Northwest, Sandia, and Los Alamos National Laboratories.
