Project Description

The aim of this effort is to conduct research and development of technologies to further advance the utilization and storage of CO2 in unconventional reservoirs while supporting the Carbon Storage Program objective of developing and validating technologies for safe and permanent CO2 storage. The effort is divided into two technical tasks:

Task 1: Sequestration in Basalt Formations – This task is conducting research to address commercial-scale injection strategies, CO2 fate and transport, and improved understanding of carbonation processes to provide a path forward for eventual commercial use of basalt formations for CO2 storage. As indicated in the figure, the research team is characterizing and evaluating carbonate mineralization and precipitation in the presence of H2O and CO2. The research team is currently investigating side wall cores and a variety of geophysical and geochemical data from the Wallula Basalt CO2 Storage Pilot Project (conducted by the Big Sky RCSP) to gain insight on a variety of silicate carbonation, post-CO2 reaction solid precipitations, and the response of the storage formation to such processes.

Task 2: Utilization in Unconventional Reservoirs – This task is enhancing the development of technologies and methodologies that will further advance the understanding of CO2 interactions in unconventional reservoirs (shales) to achieve additional hydrocarbon recovery via enhanced gas recovery (EGR) along with permanent storage of CO2. The research team is conducting characterization and modeling studies to develop a sufficient understanding of the interaction of CO2 with shales to: (1) evaluate injection concepts for secondary production of methane from depleted natural gas reservoirs, (2) refine storage capacity estimates for CO2 following EGR operations, and (3) assess safety and permanence of CO2 injected into fractured shales.

Project Benefits

The effort is focused on improving understanding of the effects of CO2 injection on unconventional CO2 storage reservoirs. Advances will contribute to the storage goals of ensuring 99 percent storage permanence and improving storage efficiency while ensuring containment effectiveness.
