California Air Resources Board (ARB) Staff invites you to
participate in a series of technical discussions on the
development of our Carbon Capture and Sequestration (CCS)
program. 

In order to ensure staff is using the best available information
and understands stakeholder concerns, we are hosting a series of
technical discussions.  The CCS technical discussions are topic
focused stakeholder-led discussions.  The intent is to allow
interested parties to provide input that will inform development
of the CCS Quantification Methodology (QM), as well as the CCS
program generally.  ARB will identify subject areas and specific
questions, with the expectation that stakeholders will provide
presentations, or other materials, and participate in an open
discussion.  

CO2 EOR Technical Discussion

Carbon dioxide enhanced oil recovery (CO2 EOR) is a tertiary
method of oil production that injects compressed CO2 into oil
reservoirs and recovers additional crude oil beyond what is
possible from the primary and secondary methods of crude
production. In doing so, CO2 EOR projects can store CO2 in oil
reservoirs.  The use of oil reservoirs for geological
sequestration may be attractive as these reservoirs were known to
have good seals that retained oil and gas for million years prior
to initial oil production. However, these seals may have been
compromised during oil extraction and may introduce potential for
CO2 leakage.  

The main goal of this technical discussion is to understand and
receive recommendations on how to deal with the risks and
particulars of permanent CO2 storage in oil fields using CO2 EOR.
 As such, we are looking to determine what considerations need to
be taken into account to ensure that the CCS QM provisions for
CO2 EOR as a storage method are robust and defensible, reservoir
mechanical integrity is maintained throughout the lifetime of CO2
EOR projects, and CO2 leaks are minimized.  The technical
discussion also seeks inputs on co-optimization of oil production
and CO2 storage.  


DATE:     Tuesday, August 23, 2016
TIME:     9:30 a.m. to 3:30 p.m.
LOCATION: Conference Room 550
ADDRESS:  Cal/EPA Headquarters Building
          1001 "I" Street
          Sacramento, California 95814

Please see ARB’s CCS website at
http://www.arb.ca.gov/cc/ccs/ccs.htm for information on
participating in and presenting at the discussion series,
including webinar access and in-person participation.  ARB will
post topic questions that are intended to guide stakeholder
presentations and the discussion prior to each discussion.  

If you have questions about the CO2 EOR Technical Discussion,
please contact Mr. Anil Baral, at (916) 327-6913 or

Background:  Carbon capture and sequestration (CCS) is an
important strategy to reduce greenhouse gas (GHG) emissions and
mitigate climate change.  CCS is a process by which large amounts
of carbon dioxide (CO2) are captured, compressed, transported,
and sequestered.  ARB is currently developing a quantification
methodology for CCS.  The CCS QM may be adopted for use in the
Cap-and-Trade and Low Carbon Fuel Standard programs as determined
appropriate in rulemaking(s) specific to these programs.  Studies
by the Intergovernmental Panel on Climate Change (IPCC) and the
California Council on Science and Technology (CCST), have shown
that CCS has the potential to reduce carbon emissions by millions
of metric tons, and may be an integral part of meeting
California’s long term climate goals.
