CFSES (Center for Frontiers of Subsurface Energy Security)
Program Overview
Gas separating apparatus

The goal of CFSES is a scientific understanding of subsurface physical, chemical and biological processes from the very small scale to the very large scale so that we can predict the behavior of CO2 and other by products of energy production that may need to be stored in the subsurface. CFSES is funded by DOE Basic Energy Sciences and is a cooperative of the The University of Texas’ Petroleum Engineering, Jackson School of Geosciences, the Gulf Coast Carbon Center, and Sandia National Lab. GCCC staff are involved in several tasks.

For Task I, Katherine Romanak is working with scientists from Sandia National Lab and UT’s Department of Geological Sciences. An apparatus for separating fluids collected from the supercritical reactor has been built and is currently being tested. (See figure) The apparatus separates dissolved gases from brines at ambient pressure and temperature for dissolved gas solubility measurements. Lab experiments on the high PT apparatus will be coupled with pore scale modeling, molecular modeling, microbial studies, and imaging the behavior of supercritical CO2.

For Task IV, Susan Hovorka and Ian Duncan, along with GCCC staff are working to provide case studies, which will be used to develop code optimized for multiscale, multiphysics processes. Cranfield is one of the few locations where dense data have been acquired to support this code development. Data compilation and clean up is underway to create a model input file, including the time lapse data needed to constrain the model in terms of lateral extent and variability in saturation.




The GCCC Mission

The GCCC seeks to apply its technical and educational resources to implement geologic storage of anthropogenic carbon dioxide on an aggressive time scale with a focus in a region where large-scale reduction of atmospheric releases is needed and short term action is possible.
