Q16_2015.pdf, Oct. 12, 2015 (Adobe Acrobat PDF file, 13 MB)

  1. Decision was made in July to build a compositional simulation of the Arbuckle saline aquifer in STOMP, the software used by EPA evaluate the AoR to facilitate the conversion from CMG simulation used by KGS to software platform used by EPA. After consultation with the developer of STOMP at Pacific Northwest National Laboratory, a methodology was developed to import the domain built in the Petrel geomodel into STOMP. The conversion process that was creating difficulties in sharing the CMG model to STOMP was subsequently solved and confirmed with EPA. Employing STOMP at the KGS will facilitate future updates. CMG is now uses the parameters, processes, and rock properties to confirm the AoR with a conservative model. The same domain and input parameters will be used in STOMP.
  2. Existing and new samples of brine from the Mississippian oil reservoir were completed in August and results and displays using java applications are now online with a methodology to normalize the data to account for systematic changes so the results can be mapped. Systematic error of the major constituents, while within the analytical tolerance of ±5%, can assignment of either spatial or temporal anomalies that could be within the real changes in the brine as the reservoir is swept by CO2.
  3. The Mississippian reservoir was revisited and updated in July and August to incorporate new data from the KGS #2-32 drilled in the previous quarter. The core obtained and the log data made a compelling case for slightly inclined stratification of high-frequency depositional cycles. Seismic was reexamined to trace this cyclicity and confirm that the small dip of a few degrees was depositional dip, not structure.

Q15_2015.pdf, Aug. 12, 2015 (Adobe Acrobat PDF file, 4 MB)

  1. The review of the Class VI application has made significant progress, and is nearing the final stages to be approved by EPA.
  2. Freshwater monitoring boreholes have been sampled and indicate no presence of a USDW at the Wellington site.
  3. CO2 suppliers have been secured.
  4. Performed workovers and obtained baseline sampling on surrounding Mississippian Boreholes for production and MVA during CO2-EOR.
  5. MVA components in place to monitor the Mississippian CO2-EOR injection, and revisited design and updated costs to fabricate U-Tube and CASSM for Arbuckle monitoring.
  6. Conducted pulse test at KGS 2-32 Mississippian well.
  7. Installed three new broadband seismometers near injection borehole.
  8. Establish Protocols for InSAR data collection.

Q14_2015.pdf, May 15, 2015 (Adobe Acrobat PDF file, 12 MB)

  1. Participated in DOE peer review in Pittsburgh on March 5.
  2. Class II application was filed with Kansas Corporation Commission in January and approved in February 2015.
  3. Continued conference calls and written communications with EPA regarding review of Class VI application. Submitted responses to requests from EPA for additional information (RAI) in regards to the application. Responded to inquiries regarding evaluation of surface water with drilling, completion, testing, and analyses fit for purpose to evaluate the presence of a USDW.
  4. Drilled and completed three shallow water wells and conducted extensive sampling, pumping, and lab work to evaluate surface waters in AOR. Findings to date is that the shallow bedrock in the AOR is primarily a low yield, brine saturated aquiclude that overlies and is in equilibrium with diffusive dissolution from the underlying shallow Hutchinson salt. Surface water in AOR and immediately vicinity is limited to thin surficial colluvium and alluvial lenses.
  5. Drilled Berexco Wellington KGS #2-32 in March 2015. Surface sampling and wireline logging above surface casing enhanced understanding of the presence of surface aquifer and aquitard system. The Mississippian oil reservoir was cored, evaluated with modern wireline logs, and is undergoing testing. The reservoir at #2-32 consists of an evenly porous (20-25% porosity) interval that is ~60 ft thick. The upper 40 ft is at residual oil saturation indicating that location has been effectively waterflooded and is in communication with one or more injection wells.
  6. KGS #2-28 will be further tested, cores will be analyzed, and models will be adjusted to determine how the reservoir is re-pressured and what the anticipated CO2 plume will be.
