Early Test Accomplishments & Key Findings
Accomplishments to Date– Monitored CO2 injection since 2008– Injection through 23 wells, cumulative volume 3.4
million tonnes– Completed repeat geophysics, including cross well
seismic, VSP, RST, and repeat surface 3-D– Recognized by Carbon Sequestration Leadership
Forum (CSLF) in 2010 for research contributions– Cranfield selected as base case for SIM-Seq inter-
partnership model development test– Early Team providing knowledge sharing to
Anthropogenic Test and other U.S./International CCS projects
Key Findings– CO2 retained in-zone, documenting no leakage to air
and no impact on water.

– CO2 saturation correctly predicted by flow modeling– Pressure (flow plus deformation) correctly predicted by modeling– Certification Framework confirms that well performance is the highest risk uncertainty
Anthropogenic Test Accomplishments & Key Findings
Accomplishments to date– Systems planning and construction is underway for a
fully integrated “commercial prototype” CO2 capture, transportation, storage and monitoring field test.
– Drilling of characterization well D9-8 #2 completed in January 2011.
– A five deep-well plus three shallow-well monitoring plan developed with assistance from Early Test.
– An initial risk registry has been developed utilizing international expertise from Det Norske Veritas (DNV).
– Participation in US-Canada and European CCS Demonstration Project Network knowledge sharing events.

Key Findings– Planning and operating an integrated CO2 capture, transportation, storage and
monitoring field test requires extensive negotiations and flexibility in plans and schedules.
– Detailed reservoir characterization and modeling is essential for designing and gaining approval for a safe, secure CO2 storage site in close proximity to the CO2 source.
SECARB Lessons Learned
Uncertainty about issues of long term liability made it difficult to secure storage sites for the SECARB field tests.
Investing significant time and effort in problem identification and risk avoidance was crucial for selecting a safe, secure CO2 storage site.
Investing in detailed site and reservoir characterization, particularly in a fluvial, complex formation, is essential.
A successful MVA program will test many tools and models but must, ultimately, lead to the selection of cost effective and robust systems for commercial deployment.
You will never have
enough information!

SECARB Future Plans
Early Test Extend the monitoring time frame at Cranfield – the capital investment has been
made and additional data collection is cost effective.
Mine existing Cranfield data and share with others to increase predictive capabilities (e.g., SIM-Seq inter-partnership model development program).

SECARB Future Plans
Anthropogenic Test Complete storage site development and transportation
infrastructure by August, 2011.
Begin CO2 injection by September 30, 2011.
Update initial risk registry with capture, transportation, injection and monitoring operations reviews.
SECARB Team Allocate additional resources to support knowledge
sharing activities.

SECARB Partnership: Specific Goals and Objectives
Early Test– Transfer technical experience to future operators regionally, nationally, and
internationally.– Predict pressure response in the far-field (single brine phase) to injection rate.– Constrain the relationship between heterogeneous flow-units and buoyant two-
phase flow. – Explore the performance of novel tool arrays.
Anthropogenic Test– Evaluate impacts of power plant CO2 capture on the transportation, injection and
long-term geologic storage operations.– Evaluate injection and storage conditions in a regionally extensive saline reservoir
to help establish regional CO2 injectivity and storage capacity.– Determine how the saline reservoir’s internal architecture can be used to optimize
storage and to minimize the areal extent of the plume. – Apply “lessons learned” at the SECARB Phase III Early Test and commercially
available, low-risk “off-the-shelf” oilfield technologies for longer-term CO2 storage and plume tracking.
– evaluate the effects of subsurface migration and trapping of anthropogenic CO2 on the geochemistry of saline reservoirs.
