|The Gulf Coast Carbon Center has been conducting a major research project in the Scurry Area Canyon Reef Operators (SACROC) oilfield near the eastern edge of the Permian Basin in Scurry County, Texas.
The Department of Energy National Energy Technology Laboratory (DOE NETL) has provided $1M in funding for the project, which is one of three Southwest Regional Partnership for Carbon Sequestration (SWP) Phase II injection experiment sites. The Kinder Morgan Company owns and operates the SACROC oilfield and graciously serves as the major industrial partner in the project. Kinder Morgan has provided over $500,000 of in-kind matching funds for the research, none of which could have been accomplished without their generous cooperation and logistical support. Dr. Brian McPherson of the University of Utah has served as principal investigator for SWP. Dr. Reid Grigg of New Mexico Institute of Mining and Technology (NMT) has lead the effort to administer the project. Rebecca C. Smyth of the GCCC at the Bureau of Economic Geology is the site manager for SWP research at SACROC and Principle Investigator for GCCC SACROC groundwater research.
The Permian Basin outlined in green covers parts of western Texas and southeastern New Mexico. SACROC oilfield, identified in red, resides on the northeastern edge of the Basin. The map also identifies both natural and anthropogenic sources of CO2 as well as the CO2 pipelines in the region.
Background and Experimental Setup
Since 1972 over 175 million metric tons of carbon dioxide (CO2) have been injected into the SACROC oil field to enhance oil recovery (EOR). About half of the CO2 has been co-produced with oil and recycled (separated from the oil and re-injected for further EOR). The remaining volume is assumed to be sequestered at 6,000 to 7,000 ft below surface. For this reason, and because SACROC oilfield has the longest history of CO2 injection of any oilfield in the Permian Basin, the site is an excellent natural laboratory for studying subsurface storage of carbon dioxide.
SACROC field experiments are being conducted on two scales. On a regional scale, research is focused on potential impacts to the shallow subsurface zones. GCCC and NMT researchers have sampled water wells as deep as 500 ft and measured CO2 soil zone concentrations within an ~800 mi2 area.
Deep subsurface experiments are centered on an experimental site that is roughly 0.4 square miles in area with CO2 injection wells located at each corner and an oil production well in the center. All of these EOR wells are 6,000 to 7,000 feet in depth. Three observation wells are located within several hundred feet of CO2 injection wells. Researchers from BEG, DOE NETL, Los Alamos National Laboratory, Schlumberger Carbon Services, and the University of Pittsburgh are attempting to monitor movement of CO2 in the deep subsurface using geophysical techniques. Geophysics data were collected before and after CO2 injection that began in October 2008.
The SWP project involves the four major areas of investigation listed below. GCCC is solely responsible for the groundwater studies. For more information on GCCC’s results, please click the links below. We intend to regularly update this page as our analysis continues.
