Gulf Coast Carbon Center
Industry-Academic Research Partnership
Assessment of options for carbon capture and sequestration
in an area of large sources and large geologic capacity
Geologic Sequestration Emplaces Dense-Phase
CO2 in Pore Systems in Rock
To reduce CO2 emissions
to air from point sources..
CO2 is captured as concentrated
is currently burned and high pressure fluid by one of several
emitted to air methods..
CO2 is shipped as dense-phase
fluid via pipeline to a selected,
permitted injection site
CO2 injected at pressure into
Carbon extracted pore space at depths
from a coal or other below and isolated (sequestered)
fossil fuel… from potable water.
CO2 stored in pore space
over geologically
significant time frames.

Objective 2.1: Guidance Manual
•Create a rigorous, comprehensive manual with pragmatic guidance in non-
technical language on best practices for selecting a geologic sequestration site
in brine-bearing formations (saline aquifers).
•Guidance derived in part from assessments of sites for Texas FutureGen –
two successful sites selected.
Objective 2.2: Reduce current uncertainty in
estimates of the capacity of brine formations

Options for Estimating Capacity
• Volumetric approach: Total pore volume x
Risk-based Volumetric
Efficiency factor (E)
– Free CO2 volume in structural and stratigraphic traps
– Trapped CO2 residual phase
• Volume dissolved
• Volume that can be stored beneath an area
constrained by surface uses or by other
unacceptable risks – well fields, faults
• Maximum pressure as a limit on capacity
• Displaced water as a limit on capacity
Effect of Depth of Formation in Storage
Volume injected/pore volume
Capacity
• Increased capacity with depth of formation
almost entirely due to higher safe injection
Goal 3: Define an Adequate and Reliable
Monitoring and Verification Strategy
Applicable to Long Term Storage
• Objective 3.1: Evaluate existing approaches for
monitoring and verification of CO2 storage in brine
formations by assessing sensitivity, accuracy and
precision of tools relative to plausible leakage
signals.
• Objective 3.2: To Develop and evaluate innovative
technologies for “Early Warning” detection of CO2
leakage
• Objective 3.3: Test an innovative approach to
monitoring and verification of CO2 storage by
combining measurements of deformation with
geomechanical modeling.

Early Warning Monitoring Options
• Atmosphere
– Ultimate receptor but dynamic
• Biosphere
Atmosphere – Assurance of no damage but
Biosphere dynamic
• Soil and Vadose Zone
Vadose zone & soil – Integrator but dynamic
• Aquifer and USDW
Aquifer and USDW – Integrator, slightly isolated from
ecological effects
• Above injection monitoring zone
– First indicator, monitor small
signals, stable.
Seal
• In injection zone - plume
Monitoring Zone – Oil-field type technologies. Will
not identify small leaks
Seal • In injection zone - outside plume
– Assure lateral migration of CO2
CO2 plume and brine is acceptable

Goal 4: Evaluation of Sources Risk and
Liability Potentially Associated with CO2
Sequestration
• Objective 4.1: Write a primer based on literature review
on risk and liability potentially associated with CO2
sequestration in the Gulf Coast
• Objective 4.2: To develop a predictive ability to evaluate
the risk of leakage of a seal for a brine formation during
and after injection.
• Objective 4.2: Assess the effectiveness of “phase
trapping” nonwetting-phase residual saturation in
lowering leakage risk in long term under various injection
conditions.
• Objective 4.3 Assess the risk of CO2 storage in brine
reservoirs to the quality of fresh water resources
