Overview

The Consolidated Sequestration Research Project (CSRP) seeks to accelerate and remove barriers to commercial-scale GCS deployment through targeted research tasks. The CSRP joins together GEO-SEQ’s fundamental research and pilot scale programs with projects in risk and basin-scale impact assessment to address key issues that arise during commercial-scale carbon storage. The management and coordination of these individual work packages will be carried out in Task 1. The GEO-SEQ program will continue as Task 2, with two primary goals:

(1) to develop ways to improve predictions of injectivity and capacity of saline formations and depleted gas reservoirs, and

(2) to develop and test innovative high-resolution methods for monitoring CO2 in the subsurface.

The GEO-SEQ project leverages scientific understanding and technology development through two highly visible, ongoing, world-class projects recognized by the Carbon Sequestration Leadership Forum (CSLF): the Otway Project and In Salah Industrial-Scale CO2 Storage Project. GEO-SEQ investigates fundamental geochemical and petrophysical processes that underpin GCS using demonstration scale pilots as testing facilities to scale up from laboratory to field scale. Additionally, GEO-SEQ will include applications of the Certification Framework risk assessment methodology for sequestration sites. 

Sim-SEQ, now Task 3, facilitates the intercomparison and evaluation of modeling activities that are performed within the RCSP program. It seeks to form a broad Technical Team consisting of both LBNL and RCSP scientists and reservoir engineers to evaluate and compare different approaches to reservoir and coupled reservoir-geomechanical and geochemical models.

The objective of Task 4, Large-scale Hydrologic Impacts of CO2 Geological Storage, is to further improve our understanding of the large-scale hydrological impacts of GCS on groundwater resources and their implications on storage capacity estimation and Area-of-Review regulation, and to develop pressure management schemes for storage capacity enhancement and CO2 leakage remediation. Task 4 will

(1) improve understanding and prediction reliability of basin-scale brine pressurization and migration through sensitivity analysis, and natural analog or RCSP Phase III field testing modeling,

(2) help to determine the impact of brine pressurization and migration on groundwater resources and provide a technical basis for Area-of-Review determination, and

(3) develop pressure management schemes, e.g., via brine extraction to improve storage capacity and remediate CO2 leakage.

Task 5 continues our collaboration with GeoForschungsZentrum, Potsdam and participation in the CSLF-recognized CO2SINK demonstration project.

The CSRP benefits from the interdependence of all of the program tasks and the close working relationship with numerous domestic and foreign industrial and academic teams. The final products of the CSRP will vary for each task, but will include DOE milestones, field and lab data collection, peer-reviewed publications, and public presentations. The value to the carbon sequestration community is 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.
