February 24-March 7, 2017    Katherine Romanak travelled to Queensland, Australia to provide expertise and conduct research in environmental monitoring for the Carbon Transport and Storage Corporation Pty Ltd (CTSCo) Surat CCS demonstration project. The project is designed to demonstrate the technical viability, integration and safe operation of Carbon Capture and Storage (CCS) in the Surat Basin. Currently in the feasibility study stage, the project is undergoing assessments and approvals in environmental, social and technical aspects, under the relevant government regulation. Romanak’s research project is funded by the Australian National Low Emissions Coal Research and Development Ltd (ANLEC R&D) on behalf of the Australian coal industry and the Australian Commonwealth government. This project will support compliance with environmental requirements for Monitoring and Verification (M&V), including early communication with CTSCo Surat Basin Project stakeholders. The research will help to define a way forward for environmental monitoring at the CTSCo Surat Basin project site and ultimately at project sites within other Australian sedimentary basins, The hypothesis being tested is that simple soil gas ratios can be used for real-time accurate environmental signal attribution, even in hydrocarbon-rich environments. Also being tested is the degree to which isotopes can be used for signal attribution. This research will give an indication of the most useful methods for environmental compliance and near-surface (M&V) at the CTSCo Surat CCS demonstration project and beyond.

Paul Jensen (ALS Laboratory group), Nick Hudson (CTSCo) and Katherine Romanak (BEG) stand beside one of the soil gas stations being used for real-time environmental monitoring at the Surat Basin CCS demonstration site. The project is upscaling and improving on Romanak’s initial design for using commercially available sensors for real-time data collection at CO2 geological storage sites.

April 20, 2016     Congratulations to Akand Islam, Alex Sun and Changbing Yang for the publication of a new paper in Scientific Reports, "Reactive Transport Modeling of the Enhancement of Density-Driven CO2 Convective Mixing in Carbonate Aquifers and its Potential Implication on Geological Carbon Sequestration." The authors studied the convection and mixing of CO2 in a brine aquifer, where the spread of dissolved CO2 is enhanced because of geochemical reactions with the host formations (calcite and dolomite), in addition to the extensively studied, buoyancy-driven mixing. They investigated nonlinear convection under the assumptions of instantaneous chemical equilibrium, and that the dissipation of carbonate rocks solely depends on flow and transport and chemical speciation depends only on the equilibrium thermodynamics of the chemical system. The extent of convection is quantified in term of the CO2 saturation volume of the storage formation. The results suggest that the density increase of resident species causes significant enhancement in CO2 dissolution, although no significant porosity and permeability alterations are observed. Early saturation of the reservoir can have negative impact on CO2 sequestration.

The paper describes the first deployment of the P-Cable (TM), a high-resolution 3D (HR3D) seismic acquisition system in the Gulf of Mexico. The instrumentation provided unprecedented resolution of depositional, architectural, and structural features related to relative sea-level change recorded in the Quaternary stratigraphy, details that are typically beyond conventional 3D seismic resolution or shallower than most commercial targets.

February 16, 2016     The Gulf Coast Carbon Center is thrilled to host an Offshore CCS Workshop in partnership with SANEDI (South African National Energy Development Initiative), IEAGHG, and the Carbon Sequestration Leadership Forum. The Workshop will be held April 19-21, 2016, and its goals include forming a global needs assessment for offshore CCS, initiating a discussion about the various aspects of offshore transport and storage, and building an international community of parties interested in offshore storage. The workshop will facilitate countries to identify their specific issues, challenges, opportunities, etc., identify synergies, common gaps and goals, and define common action items. We will be posting links to more information and registration as soon it becomes available.
February 8, 2016     Congratulations to Alex Sun, Jiemin Lu, Susan Hovorka, and Akand Islam, along with co-author Barry Friefeld for their publication "Using pulse testing for leakage detection in carbon storage reservoirs: A field demonstration" in the International Journal of Greenhouse Gas Control. The paper proposes time-lapse plus testing as a pressure-based monitoring technique for carbon storage reservoirs. The technique is successfully demonstrated and validated at a CO2-EOR site in a series of experiments. The results show that leakage events caused a significant deviation in amplitude of the frequency response function, indicating that pulse testing may be deployed as a cost-effective active monitoring technique, with potential for automated monitoring.
February 3-4, 2016     Global CCS Institute's Fifth Annual Americas CCS/CCUS Forum. Rebecca Smyth represented GCCC at the meeting whose aim was to bring together senior level government, industry, academic, and environmental NGO leaders to discuss opportunities and challenges associated with CCS/CCUS and the policies and actions needed to enable its broad deployment post Paris COP21. Washington, DC
January 25-26, 2016     First US-Japan CCS Collaboration Meeting. Tip Meckel attended the meeting which included discussion of current CCS research topics in Japan and the U.S. Members of US-DOE, RITE, and Japan METI were in attendance. Meckel also participated in a site tour of the Tomakomai CCS Demonstration Project on the southern coast of Hokkaido, which is nearing completion. Tokyo, Japanclick to see larger image

January 13-15, 2016     International Offshore CO2 Storage Roundtable. The 2-day roundtable aimed to identify the next step for CO2 offshore storage research and demonstration in South China. More than 40 distinguished Chinese and International CCUS experts attended including GCCC's Tip Meckel who presented a talk on five offshore research projects in North America. The meeting also included a visit to the Dongguan Low-carbon Industry Park. Beijing and Guangzhou, China
January 8, 2016     Congratulations to Akand Islam, Tip Meckel, and Alex Sun, along with co-author P.G. Krishnamurthy, who have just published the paper, "Numerical experiments of density driven CO2 saturated brine migration in heterogeneous two-dimensional geologic fabric materials" in the journal International Communications in Heat and Mass Transfer. Results indicate that course sands are better candidates for CO2 dissolution and than silts and that gravity drives more vertical saturation than horizontal. The range in grain size is the primary driver of convective and dissolution processes, and the correlation length of the sedimentary fabric has a minor impact.

Carbon dioxide, produced by combustion of fossil fuels, exceeds global assimilative capacity and may result in negative impacts on the ocean and climate. The Gulf Coast Carbon Center (GCCC) seeks to impact global levels of atmospheric greenhouse-gas emissions by

  • Conducting studies on geologically sequestering CO2 in the deep subsurface, focusing on the Gulf Coast,
  • Educating the public about risks that might limit deployment and measuring the retention of CO2 in the subsurface, and
  • Enabling the private sector to develop an economically viable industry to sequester CO2 in the Gulf Coast area.
