Highlights of field trips to Cranfield include a tour of Denbury Resources' gas-separation facility, venting of CO2 from a flow line at an injection well, viewing of core of the injection and confining zone intervals of the Tuscaloosa Formation, and viewing of monitoring instrumentation designed and operated with funding from the National Energy Technology Laboratory in collaboration with Sandia Technologies, LBNL, ORNL, USGS and LLNL.
BEG research at Cranfield, part of the Phase 3 SECARB regional partnership program in sequestration managed by the Southern States Energy Board, has effectively monitored a million-ton injection with diverse methodologies.

Background Information: The Bureau of Economic Geology Gulf Cost Carbon Center at The University of Texas at Austin is currently conducting a $34 million multi-year field study of sequestration and monitoring strategies for long-
term storage of carbon dioxide. The work is being performed in conjunction with the Southeast Regional Carbon Sequestration Partnership (SECARB) with support from the National Energy Technology Laboratory and the U.S. Department of Energy (DOE) and managed by the Southern States Energy Board (SSEB). The SECARB partnership is demonstrating CO2 injection rate and storage capacity in the Tuscaloosa-Woodbine geologic system that stretches from Texas to Florida. The Gulf Coast Carbon Center's work has contributed to injection of over one million tons of CO2, into brine up to 10,000 feet (3,000 m) below the land surface near the Cranfield oil field about 15 miles (24 km) east of Natchez, Mississippi. The project involves numerous industrial partners, scientific collaborators, and technical subcontractors, each of whom is responsible for different aspects of the study:
The Gulf Coast Carbon Center is responsible for geologic characterization, monitoring design, integration, and near-surface monitoring.
Denbury Resources, Inc. is the site host. They are also responsible for the well preparation and supply the CO2 for storage and sequestration.
Sandia Technologies LLC is responsible for subsurface monitoring systems design and deployment.
Schlumberger Carbon Services is responsible for wireline logging and interpretation.
Lawrence Berkeley National Lab is responsible for cross-well, VSP and Continuous Active Seismic Source Monitoring (CASSM). Implementation and evaluation of of noble gas and other tracers and the U-tube and Distributed Temperature System (DTTS).
Lawrence Livermore National Labs and Promore are responsible for cross well Electrical Resistance Tomography (ERT).
University of Mississippi and Mississippi State University are responsible for groundwater monitoring.
For a technical log of research by the Gulf Coast Carbon Center at Cranfield, please visit the Cranfield Log hosted by the Gulf Coast Carbon Center. The log documents the Gulf Coast Carbon Center's progress toward developing a process for safe, long-term, subsurface sequestration of carbon. No other project in the United States has incorporated so many different geological and technical measurements and we expect to accumulate significant information and experience that will increase confidence and decrease costs of future geologic carbon sequestration projects. Much of this information will be transferred to professionals, professors and teachers, students and the public through efforts with STORE.
