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.

February 22-24, 2016     International Standards Organization. Susan Hovorka will meet with a working group of ISO, which is developing consensus on a method of accounting for CO2 injected for oil recovery as part of an CO2 EOR process. Amsterdam, The Netherlands
February 22,2016     Congratulations to Tip Meckel and former GCCC student Francis Mulcahy for the publication of their paper, Use of novel high-resolution 3D marine seismic technology to evaluate Quaternary fluvial valley development and geologic controls on shallow gas distribution, inner shelf, Gulf of Mexico. 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.

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.
