The Consolidated Sequestration Research Project (CSRP) sought to accelerate and remove barriers to commercial-scale GCS deployment through targeted research tasks. The CSRP joined together GEO-SEQ’s pilot scale programs and supporting fundamental research with projects in simulation, including basin-scale impact assessment and CO2-EOR simulation, to address key issues that arise during commercial-scale carbon storage.
CSRP had the following task structure:
Task 1: Management and coordination of the individual work packages
Task 2: The GEO-SEQ project had two primary goals:
(a) to develop ways to improve predictions of injectivity and capacity of saline formations and depleted gas reservoirs, and
(b) to test innovative high-resolution methods for monitoring CO2 in the subsurface.
The GEO-SEQ project leveraged scientific understanding and technology development through two highly visible, ongoing, world-class projects recognized by the Carbon Sequestration Leadership Forum (CSLF): the Otway Project (subtask 2.1) and In Salah Industrial-Scale CO2 Storage Project (subtask 2.2). Additional monitoring and pilot site support will include work with GeoForschungsZentrum, Potsdam for participation in the CSLF-recognized CO2SINK demonstration project (2.3), and collaboration with the Canadian Aquistore Pilot (subtask 2.4) operated by Saskatchewan’s Petroleum Technology Research Centre (PTRC), a non-profit research organization.
Task 3: Suport for GEO-SEQ with investigations of fundamental geochemical and petrophysical processes and monitoring technologies that underpin GCS using demonstration scale pilots as testing facilities to scale up from laboratory to field scale.
Task 4: Support simulation studies including (4.1) Large-scale Hydrologic Impacts of CO2 Geological Storage, (4.2) Sim-SEQ which is facilitating the intercomparison and evaluation of modeling activities that are performed within the RCSP program, (4.3) CF-CO2-EOR which transitions the Certification Framework risk assessment task to development of rigorous CO2-EOR simulation capabilities built on the TOUGH+ foundation with focus on both injection-related processes and long-term CO2 trapping and leakage studies, and (4.4) Stochastic Inversion which links together simulation, monitoring, and joint data inversion in a comprehensive framework.
CSRP produced significant scientific results as demonstrated by a large number of conference presentations, invited talks and publications. In addition to the international research programs within the GEO-SEQ task, the CSRP maintained collaborative relationships with two European CO2 sequestration research consortia – the MUSTANG Consortia coordinated by Uppsala University in Sweden, and the CO2CARE program, coordinated by the Helmholtz Center, GFZ, Potsdam, Germany. Additionally, we were involved in the installation of equipment at the Aquistore Project in Canada, collaborating with the Canadian PTRC to incorporate fiber-optic monitoring technologies into their well-based program. This was incorporated into the GEO-SEQ task.
CSRP benefited from the interdependence of all of the program tasks and the close working relationship within LBNL and with numerous domestic and foreign industrial and academic teams. The value to the carbon sequestration community was the interaction and assistance to RCSP and CSLF projects as well as publications/presentations available to all parties interested in removing barriers to commercial-scale GCS.
CSRP related research concluded at the end of FY15. Some related work will continue under the new Core Carbon Storage and Monitoring Research (CCSMR), which started at the beginning of FY15.
