Arbuckle Saline Aquifer Modeling

Presentation given at NETL Carbon Storage R&D Project Review Meeting: Prototyping and testing a new volumetric curvature tool for modeling reservoir compartments and leakage pathways in the Arbuckle saline aquifer: reducing uncertainty in CO₂ storage and permanence, by Jason Rush.

9th Quarterly Report, February 2013, 59 MB. "Accomplishments this quarter include: (1) ASME project peer review; (2) completed facies and structural interpretation of McCord-A 20H image log; (3) classified facies and constructed facies probability maps; (4) completed construction of final facies logs and facies model; (5) constructed final fault model; (6) constructed final porosity model; and (7) constructed permeability model."

7th Quarterly Report, August 2012, 3 MB. "Major results from this quarter include: (1) simulation and history matching of the pre-spud geocellular model; (2) completion of the petrophysical evaluation for the McCord-A 20H logs; (3) inclusion of the seismic inversion volume into the porosity modeling workflow; and (4) delivery of thin sections corresponding to the L. Hadley-4 core analyses, which will be used to constrain rock fabric-petrophysical relationships (i.e., facies model)."

3rd Quarterly Report, July 2011 online. "The Bemis-Shutts' 3D seismic volumes have now been successfully merged, reprocessed, and depth-converted. Horizon interpretation is also complete. Decision Point 1 is associated with the completion of these subtasks. The Go/No Go decision is based upon whether or not features exist within the seismic volume that are indicative of Arbuckle paleokarst (official evaluation will be delivered to DOE Project Manager as a separate document)."

The study will evaluate the effectiveness of a new seismic tool to identify the presence, extent, and impact of paleokarst heterogeneity on CO₂ sequestration. The Arbuckle saline aquifer in southwestern KS is an ideal candidate for CO₂ sequestration because of thickness (600-1000 ft), supercritical depth (>3500 ft), stratigraphic isolation from freshwater aquifers, and very limited oil and gas production.
