October 2013: New High-Resolution Seismic Survey in Gulf of Mexico. A second 3D seismic survey using the new P-Cable acquisition system was successfully completed during ten days of data collection off the Texas coast in October. The system, which includes dense data collection from 12 streamers and 96 channels, is designed to provide extremely high-resolution 3D data for relatively shallow stratigraphic depths (<1500 m). The BEG is the only research institution in the United States currently operating such a P-Cable seismic acquisition system. GCCC's Tip Meckel led the survey and Ramon Trevino led the logistical coordination from shore. Participants included BEG's Dallas Dunlap, Nathan Bangs from the Institute for Geophysics, and Ben Phrampus, a graduate student from SMU.
A single-channel field record from the recent survey shows a salt dome approaching the seafloor in the center part of the survey.
During the October cruise over 400 line-km were shot in an area offshore southern Galveston Island adjacent to and including portions of the San Luis Pass shallow salt dome. The survey imaged subsurface stratigraphy and structure above a Miocene-age CO2 storage prospect at ~2,000 m depth. The data will be analyzed to understand geologic seal and fluid systems. Interest from industry in a subsea carbon storage repository has been building, and acquiring datasets such as those collected using the P-cable system are important for developing a variety of commercial applications of high-resolution 3D technologies.

The survey was performed from the R/V Brooks McCall based out of Freeport, TX, and operated by TDI-Brooks International, Inc. of College Station. NCS Subsea provided navigation support. The research cruise was funded through DOE-NETL's carbon sequestration research program and the Texas General Land Office as part of a multi-year effort to characterize potential CO2 storage sites in the near-offshore Gulf of Mexico.
BEG's first P-Cable survey in the San Luis Pass region was completed in July 2012. Data processing of both surveys is ongoing and one more GOM acquisition survey is planned for 2014.

October 24, 2013: Special Issue on Cranfield Marks a Milestone
A special section of the October issue of the International Journal of Greenhouse Gas Control is dedicated to CCS work at Cranfield Field, Mississippi. The section comprises a mid-project overview and assessment of the CCS field work, dense data collection, and analysis that began a decade ago with the formation of the Southeast Regional Carbon Sequestration Partnership and that continues today at Cranfield Field. The section consists of sixteen papers authored by GCCC staff and their colleagues. It opens with a discussion of the Cranfield project design and covers risk assessment, characterization, injection and production activities, as well as monitoring techniques and modeling.
The publication of this collection of papers is a gratifying milestone for the GCCC. The volume was guest-edited by Susan Hovorka, Tip Meckel and JP Nicot. Nicot commented, "This is the first exhaustive document of the Partnership's projects, and it will be useful to the entire CCS community."

October 1, 2013: "Greensites and brownsites: Implications for CO2 sequestration characterization, risk assessment, and monitoring" was authored by Brad Wolaver, Susan Hovorka, and Becky Smyth and published in the International Journal of Greenhouse Gas Control. The paper characterizes differences between sites lacking previous subsurface development, or greensites, and sites where the subsurface has been developed, or brownsites, as they pertain to CO2 injection for storage and for EOR. Greensites are typically more stable, and thus a simpler environment for characterization and monitoring, while at brownsites legacy infrastructure and contamination must be evaluated so that leakage signals are not mimicked or masked. These differences should be recognized in policies and regulations.
September 10, 2013: A new letter comparing several cases for understanding the economic viability of capturing large quantities of anthropogenic CO2 from coal-fired power generators within the ERCOT electric grid and using it for pure CO2 enhanced oil recovery (EOR) in the onshore coastal region of Texas along the Gulf of Mexico has been authored by Cary King, Gürcan Gülen,Stuart Cohen, and Vanessa Nuñez-Lopez and published in Environmental Research Letters.

Seyyed Hosseini designed and tested a novel approach for monitoring the CO2 presence in above zone monitoring intervals in a Gulf Coast region CO2-EOR oil field south of Houston. This approach is based on repetitive pulse testing between two or more wells perforated in the monitoring sands to assess the change in compressibility of the formation over the time, a sign of possible CO2 leakage from deeper zones.

June 7, 2013: Much research has addressed the flow of CO2 driven by pressure gradients such as occur near injection wells. Less attention has been paid to the flow conditions of CO2 far from injection wells where pressure gradients are reduced and flow is dominated by buoyancy and capillarity. A recent publication in the Journal of Sedimentary Research by GCCC researcher Tip Meckel addresses the complexities that small scale depositional heterogeneity of rock properties (permeability and capillary entry pressure) can have on flow migration pathways driven by buoyancy. The paper reinforces the importance of local capillary trapping. Flow moves in extremely narrow pathways with dense saturation, but bulk rock saturations remain low. Understanding this flow regime is important for appreciating CO2 migration potential, capacity, and also for monitoring aspects such as seismic imaging at plume margins.
