CSLF Technical Group Activities
The CSLF Technical Group is comprised of world-class experts in the areas of carbon dioxide (CO2) capture, CO2 storage, CO2 enhanced oil recovery (CO2-EOR), and other forms of CO2 utilization. It has been active, via task forces and working groups, in many areas related to carbon capture and storage (CCS). At the CSLF Ministerial in November 2015 in Riyadh, Saudi Arabia, the CSLF Technical Group recommended three new taskforces for the Technical Group to pursue: offshore CO2-EOR; bioenergy with CCS; and improved pore space utilization.
Offshore CO2-EOR has not really taken hold, with only one large-scale project in Brazil underway. The reasons for the slow adoption of this technology may be many, including different reservoir characteristics than onshore; higher recovery rates in many offshore fields than onshore thus lowering benefits; fewer wells due to horizontal drilling; and expensive modification on platforms. This task force will summarize the current state of the technologies involved, including the additional monitoring techniques that may be applied offshore CO2-EOR, which will position the CSLF to better encourage its members to implement these technologies.
Biomass power generation or biomass to fuels has the potential for negative carbon emissions when combined with CCS. This task force will look at the current global status of biomass applications and the potential application of CCS and technology gaps or challenges.
With the straightforward manner of CO2 injection, in particular for saline formations, a large portion of available pore space in a geological storage site is bypassed. Being able to improve pore space utilization may be very beneficial in terms of increased storage capacity, reduced monitoring costs, and increased ability for ‘hub’ style storage operations. Options include: optimizing well(s) configuration and orientation; targeted injection in regions of higher heterogeneity, lower permeability, and/or higher residual trapping potential; plume steering; pressure management; and alternating injection of CO2 gas and CO2 dissolved in water. This task force will investigate the various published options, and review the effectiveness and readiness of these techniques to improve the pore space utilization. Results will be a set of options for stakeholders to develop into their storage projects.
In addition to the three new areas of work mentioned above, the CSLF Technical Group manages and executes efforts under the CSLF Project Interaction and Review Team (PIRT).
The CSLF PIRT has the main responsibility of engaging sponsors of CCS projects. Learnings from these projects are key elements to knowledge sharing which will ultimately assist in the acceleration of the deployment of CCS technologies. PIRT responsibilities include:
