NETL

This database and toolset were created within the Research and Innovation Center at the Department of Energy National Energy Technology Laboratory (NETL). This work was conducted as part ongoing work to characterize relative permeability of carbon dioxide (CO2) and in-situ brine within both conventional and unconventional reservoir types for the purposes of CO2 sequestration and enhanced oil recovery. The database is an attempt to broadly characterize multiple depositional environments, per the NETL carbon storage atlas (reference), for the purposes of identifying target reservoirs for exploitation and providing freely accessible data that is otherwise computationally and financially prohibitive to obtain.

Methodology

Methodology Infographic

Experimental setup description: core held in core holder with confining pressure?, flooded with brine solution, supercritical CO2 injected. During injection pressure at inlet and outlet of core is measured. Injection measured in terms of pore volumes injected. During injection CT images captured with Toshiba AquilionTM RXL medical CT scanner.
