Status on AFE for basement test in SW Kansas

Drill within allocated budget--$1,914,340

  • DOE budget for drilling is based on proportionate cost for basement test at Wellington Field with Beredco rig including 1600 ft of core.
  • Bids to date for SW Kansas basement test have exceeded this amount.
  • Round two AFEs requested with adjustments:
    1. Set the cost of wireline logging at $105,000.
    2. Limited drill stem tests to five intervals.
    3. Reduced the cost of tubing to rental cost.
    4. include wellsite geologist, but remove costs for mud logger.
    5. No contingency costs allowed by DOE.
    6. Run casing but limit perforating and swabbing to five intervals in Arbuckle and above the Arbuckle such as the Viola.
    7. Include no costs for stimulation.
    8. Include cost to run pressure buildup tests on three flow units in the Arbuckle to better understand their properties as per our statement of work with DOE.
  • Only Cimarex submitted revised 2nd round AFE on 12/12, but cost still exceeded the budget.

To reduce AFE costs, reduce core from 2100 ft to 1200 ft

  • Dana Wreath is working with coring contractors to improve coring bids including reducing amount of aluminum liner.
  • Submit revised AFE
    • Dana Wreath plans to submit a bid for drilling in Cutter Field once coring bid has been refined.
  • Basement test at Shuck field in Seward County is ~8300 ft, 1000 ft deeper than to the north. Revised AFE is less likely to be reduced to be within budget. Also, question if more coring is necessary in the Chester reservoir with 8 other cores available?

FE-DE0002056--Project highlights and accomplishments


  • Regional Well Database to estimate CO2 storage capacity. The 25,000 square mile regional dataset in southern Kansas study area includes a comprehensive 95,000 well inventory. 14,105 Arbuckle tests have been identified and used in mapping. 1,417 type wells have been scanned and depth-registered, each with modern log suites with <200 ft penetration into Arbuckle. Digitized logs from 263 supertype wells that have greater than 400 ft penetration into the Arbuckle. 199 stratigraphic type logs across Kansas representing shallowest and deepest penetrations to use to assess regional distribution of shallow freshwater aquifers, deep saline aquifers, and caprocks and sealing strata. There key wells correlated with 37 formation tops.
  • Web-based application developed to 1) perform basic analysis and visualization of lithology, petrophysical properties, and pore space characterization on digital well logs to identify flow units and barriers to flow, 2) annotate logs with sample/core descriptions, analyses, and stratigraphic nomenclature, 3) save compiled information in new LAS 3.0 format, and 4) construct cross sections from LAS 3.0 files to illustrate key logs.
  • Assemble and analyze 4,512 drill stem tests in regional study area for pressure and salinity.
  • Developed interactive project mapper to access and download well data and maps used in the regional assessment, field studies, and regional modeling sites.
  • Integrate and interpret over 200 mi2 of donated seismic data in SW Kansas and use with regional well mapping, reprocessed gravity-magnetic data, and remote sensing to evaluate fault and fracture systems.
  • Wellington Field characterization includes acquisition, processing, and interpretation of 11 square mile 3D multicomponent seismic, 7.5 miles of 2D shear wave seismic surveys, two basement tests with nearly 1600 ft cored from upper Cherokee shale caprock, Mississippian oil reservoir, and 1000 ft thick saline Arbuckle aquifer. Ran extensive set of routine whole core analyses, CO2 capillary pressure and relative permeability, mechanical properties, and helical CT scans. Ran exhaustive modern log suites in both wells including nuclear magnetic resonance, dipole sonic, and geochemical log. Conducted pulse rate test in 20 ft thick interval of lower Arbuckle to demonstrate communication between wells 3000 ft apart.
  • Collected 201 plugs from core and six sets of DST derived water from wells drilled in Wellington Field to study via X-ray diffraction, SEM, thin section, and ambient and "at reservoir pressure" flow experiments at NETL and KState lab in the presence of CO2 to characterize flow units and caprocks and measure reaction kinetics to improve simulation models.
  • Integrated well, core, seismic and fluids data on four Chester and Morrow oil fields in SW Kansas to make them ready for CO2-EOR and to test deep saline aquifer.
  • Building 2nd generation Petrel 3D model and CMG simulations in Wellington Field to evaluate CO2-EOR in the Mississippian tripolite reservoir of Wellington Field and for geosequestration and Class VI permit in the underling deep saline aquifer.
  • Evaluating source-sinks including working with Clinton Foundation on pipeline infrastructure.


  • Established and correlated regional internal stratigraphy of the Arbuckle saline aquifer with multiple data with multiple flow units and intervening baffles within the aquifer. Significant regional changes generally correspond to Precambrian basement heterogeneities.
  • Established that Arbuckle deep saline aquifer is an open system connected to surface exposures at least 150 miles to the east on the Ozark Uplift.
  • Basic site evaluation completed on 10 candidate sites for additional simulation beyond oil field to help calibrate capacity estimates of Arbuckle deep saline aquifer. Preliminary volumetric estimate of regional CO2 storage capacity.
  • Recognized abrupt change in water chemistry at 4900 ft in lower Arbuckle at Wellington Field that corresponds with the top of lowermost flow unit and prospective injection zone.
  • Areas in western Kansas and Western Annex region have reduced thickness of shales in lower Paleozoic and distribution of tight Mississippian evaporites and argillaceous carbonates are being examined in area for their caprock qualities.
  • Regional structure maps reflect verified faults. Some deep seated faults are being characterized with donated regional 3D seismic in SW Kansas that reside near and alongside one of the oil fields that are being studied. Karst is also developed in associating with the faulting from dissolution of Spergen-age Mississippian anhydrites. Vertical extent of these generally limited to base of Pennsylvanian, indicating activity has ceased and affect strata well below surface freshwater and intervening caprocks.
  • Established ongoing dialogs with Kansas petroleum industry, Kansas Legislature and Governor, state and federal regulators, and local landowners in the Wellington field area.
