چکیده انگلیسی
This work used mercury injection capillary pressure (MICP) analyses of the Tuscaloosa Group in Mississippi, including the Tuscaloosa marine shale (TMS), to assess their efficacy and sealing capacity for geologic carbon dioxide (CO2) sequestration. Tuscaloosa Group porosity and permeability from MICP were evaluated to calculate CO2 column height retention. TMS and Lower Tuscaloosa shale samples have, respectively, Swanson permeability values less than 0.003âmd and 0.00245âmd; porosity from 3.86% to 9.86% and 1.34% to 7.96%; median pore throat sizes from 0.00342 to 0.0111âμm and 0.00311 to 0.017âμm; and pore radii from 0.0130 to 0.152âμm and 0.0132 to 0.149âμm. Mercury entry pressures for the TMS and Lower Tuscaloosa range from 4.9 to 57.1âMPa and 5.0 to 56.3âMPa, respectively. Calculated CO2 column heights that the TMS sample set can retain in the reservoir range from 23 to 255âm when the TMS is near 100% water saturation. Potential top seal leakage is more likely to be influenced by the numerous well penetrations through the confining system of the TMS rather than capillary failure. Results of this study demonstrate desirable sealing capacity of the TMS for geologic CO2 sequestration in reservoir sandstones of the Lower Tuscaloosa and could provide an analogue to other potential CO2 sequestration top seals.
