Geology Of The Kentucky Geological Survey Marvin Blan No. 1 Well, East-Central Hancock County, Kentucky, J. Richard Bowersox, David A. Williams

Report of Investigations--KGS

The Kentucky Geological Survey’s Marvin Blan No. 1 well was drilled in east-central Hancock County, Ky., about 4 mi southwest of the Ohio River, to demonstrate CO₂ injection in the Western Kentucky Coal Field, following the mandate and partial funding from Kentucky’s House Bill 1, August 2007. Installation of a groundwater monitoring well was required as a condition of obtaining a U.S. Environmental Protection Agency Underground Injection Control Class V Permit prior to drilling the Blan well; however, no groundwater was encountered under the Blan well site. The groundwater monitoring well was immediately plugged and abandoned in accordance with …

Shallow Groundwater Monitoring Associated With The Deep Saline Reservoir Co2 Storage Test In Hancock County, Kentucky, E. Glynn Beck

Report of Investigations--KGS

A carbon dioxide injection test well was drilled in 2009 to a depth of 8,126 ft below ground surface in Hancock County, Kentucky. Six hundred ninety tons of CO₂ was successfully injected into Knox Group saline aquifers. Two domestic wells (MB and GB) and two domestic springs (CA and RC) were sampled to monitor any potential changes in groundwater quality associated with possible migration of CO₂ from deeper saline aquifers into shallow freshwater aquifers. The four sites were sampled for pH, bicarbonate, total dissolved solids, turbidity, anions, total dissolved metals, dissolved inorganic carbon, total CO₂, and …

Hydrogeologic Investigations Of Pavement Subsidence In The Cumberland Gap Tunnel, James S. Dinger, James C. Currens, Junfeng Zhu, Steven E. Webb, Brad W. Rister, R. C. Graves, David L. Allen, Tim C. Scully

Report of Investigations--KGS

Cumberland Gap Tunnel was constructed under Cumberland Gap National Historical Park in 1996 to improve transportation on a segment of U.S. 25E, connecting Kentucky and Tennessee and restoring Cumberland Gap to its historical appearance.

The concrete pavement in the tunnel started to subside in 2001. Ground penetrating radar surveys revealed voids in many areas of the limestone roadbed aggregate beneath the pavement. To investigate possible hydrogeologic processes that may have caused favorable conditions for voids to form in the aggregate, we studied geology, groundwater flow, and groundwater chemistry in the tunnel using a variety of methods, including bore drilling, packer …

Using Time-Lapse Three Dimensional Vertical Seismic Profiling To Monitor Injected Fluids During Geologic Carbon Sequestration, John B. Hickman

Report of Investigations--KGS

Two three-dimensional vertical seismic profiles (3D-VSP) were acquired at the KGS Marvin Blan No. 1 CO₂ sequestration research well outside of Cloverport in Hancock County, Ky. The initial (preinjection) survey was performed September 15-16, 2010, and was followed by the injection of 361.2 metric tons of supercritical CO₂ and then 584 m³ of 2 percent potassium chloride water (to displace the remaining CO₂ in the wellbore) on September 22, 2010. After injection, the well was shut in with a downhole pressure of 17.5 MPa at the injected reservoir depth of 1,545.3 m. A second 3D-VSP was …
