The Regional Carbon Sequestration

Partnership (RCSP) Initiative

3

The RCSP is a DOE funded cooperative agreement of seven

regional Partnerships

Tasked with:-

Determining best geologicalstorage approaches for each

region

- Application and assessment of

storage technologies todemonstrate permanent storage

Anthropogenic Test Project Background

The SECARB Anthropogenic Test is a fully

integrated Carbon Capture and Storage

project

CO2 is captured from SouthernCompanys Plant Barry (a 2,657 MW

coal-fired power plant)

A ~12 mile pipeline delivers the CO2to Denburys Citronelle Oilfield

The captured CO2is injected into thesaline bearing Paluxy formation

(~9,400 feet deep)

Approximately 114 thousand metric

tons of CO2were injected between8/12 and 9/14

Capture and Compression

7

Plant Barry, Alabama

CO2 is captured from a 25 MW

slipstream from Plant Barry Flue Gas

- (2,600 MW system)

500 tonnes/day capture capacity

CO2is captured and compressed

using Mitsubishi Heavy Industries

compression technology


8/32

8

Flue gas first reacts with KS-1 amine-based solvent

CO2is released from the solvent

CO2 is then compressed to a supercritical state (to 1500 psi)

Study Area Background

The Citronelle Oilfield lies atopthe Citronelle Dome

What makes the Citronelle Dome amenableto CO2sequestration?

Well defined reginal geology from oil exploration

and production

Gulf coast sediments comprise excellent qualityreservoirs

A proven structural trap

Structural closure is exhibited in all directions

The limbs of the dome gently dip ~1

Confining Zone

Pixelized difference tomography results without seismicreflection overlay showing positive velocity differencesin warm colors and negative differences in cool colors

First arrivals from repeat surveywere of sufficient quality to

produce a velocity difference

image (right) showing regions

where seismic velocity has

changed over time

Time-lapse difference image

indicates a decrease in seismic

velocity in the upper injection zone

of up to 3%, suggesting an

increase in CO2saturation

Time-Lapse Differencing Using the

Baseline and Repeat Velocity Tomograms

More importantly, no negative velocityanomalies are observed in or above

the confining unit!implying nodetectable leakage out of inj. zone

No significant negativevelocity anomalies

Decrease in velocity(negative anomaly)

Predicted Radial CO2Plume Extent on

October 31, 2017 of 600 ft

Despite the high permeability of the formation and a gentle dip, there is nota substantial change in the plume extent in the three years following the

cessation of injection.

In fact, the plume extent has equilibrated.

This is due to injection into multiple zones, the limited injection volume and

injection shut ins which allowed for equilibration during the injection phase
