Evaluation Of Geologic Co2 Sequestration Potential And Co2 Enhanced Oil Recovery In Kentucky, Thomas M. Parris, Stephen F. Greb, Brandon C. Nuttall Jan 2010

Evaluation Of Geologic Co2 Sequestration Potential And Co2 Enhanced Oil Recovery In Kentucky, Thomas M. Parris, Stephen F. Greb, Brandon C. Nuttall

Report of Investigations--KGS

Kentucky gets approximately 95 percent of its electricity from coal-fired power plants, which produce significant amounts of carbon dioxide (CO2). In 2005, Kentucky coal-fired plants vented 102.8 million short tons of CO2 into the atmosphere. The economic vitality of the state will be affected by its ability to develop and apply a portfolio of technologies that will mitigate input of CO2 into the atmosphere. One technology that has the potential to assist in this challenge is geologic carbon storage, which captures CO2 at point sources and injects it into deep rock strata that can store …


Foundation Problems And Pyrite Oxidation In The Chattanooga Shale, Estill County, Kentucky, Warren H. Anderson Jan 2008

Foundation Problems And Pyrite Oxidation In The Chattanooga Shale, Estill County, Kentucky, Warren H. Anderson

Report of Investigations--KGS

Pyrite oxidation in the Chattanooga Shale has caused serious foundation problems in numerous buildings and structures in Estill County, Ky. Pyrite oxidizes and various secondary sulfates form when excavated shale or shale fill are used in foundations. These secondary sulfates are water- and humidity-sensitive and can form when only minor amounts of water are present in foundation materials. These sulfates form by crystal growth and expand by volume change, which causes subsequent soil expansion and heaving of any foundation materials when the materials are confined. Several structures have undergone expensive remediation to repair damaged sidewalks, floors, walls, and foundations. Zones …

Source Scaling, Subevent Distributions, And Ground-Motion Simulation In The Composite Source Model, Baoping Shi, Zhenming Wang, Edward W. Woolery Jan 2006

Source Scaling, Subevent Distributions, And Ground-Motion Simulation In The Composite Source Model, Baoping Shi, Zhenming Wang, Edward W. Woolery

Report of Investigations--KGS

Predicting strong ground motion from a large earthquake depends to a large extent on the development of a realistic source model. Strong ground motion was simulated using the composite source model. F0or comparison purposes, two different approaches were implemented in the source procedure simulation. For the first approach, the source was taken as a superposition of circular subevents with a constant stress drop. The number of subevents and their radii followed fractal law distribution, specified as a spatial random field, and subevents were allowed to overlap. This resulted in the total area of the subevents being much greater than the …

Using Remote Sensing And Inclined Drilling To Locate High-Yield Water Wells In The Eastern Kentucky Coal Field, Robert E. Andrews, David R. Wunsch, James S. Dinger, Glenn A. Dunno

Report of Investigations--KGS

The Kentucky Geological Survey has developed a method using lineament analysis in conjunction with inclinced exploration boreholes to identify subsurface fractures in the Eastern Kentucky Coal Field. Wells are then drilled to intersect these fractures, with the hope that the wells will be high yielding (greater than 30 gal/min). Lineaments were selected from Landsat TM imagery, side-looking airborne radar (SLAR) imagery, and two enhanced Landsat TM images for over 6,400 square miles of eastern Kentucky. Lineaments were replotted on 7.5-minute topographic quadrangle maps, and field reconnaissance identified locations where lineaments correlated with straight-line topographic features and fracture zones. Subsquent application …

Hydrogeologic Conditions Around Deep Aeration Lagoons At The Bardstown Wastewater Treatment Plant, David R. Wunsch, Gregory L. Secrist, Lyle V.A. Sendlein

Report of Investigations--KGS

The hydrogeologic conditions around the Bardstown Sewage Treatment Plant were studied from August 1996 through December 1997. Hydraulic and geochemical data were collected from eight monitoring wells and four surface-water monitoring sites on the plant property.

There is a large hydraulic gradient between the lagoons at the plant and the surrounding stream, Town Creek. Initial water-level measurements in wells surrounding the site suggest no major leakage from the lagoons, however. Neither flowing artesian conditions nor unusually high water levels were observed in any of the wells. Water-level measurements collected by data loggers showed that shallow wells responded quickly to recharge, …

Available Resources Of The Fire Clay Coal In Part Of The Eastern Kentucky Coal Field, Stephen F. Greb, Gerald A. Weisenfluh, Robert E. Andrews, John K. Hiett, James C. Cobb, Richard E. Sergeant Jan 1999

Available Resources Of The Fire Clay Coal In Part Of The Eastern Kentucky Coal Field, Stephen F. Greb, Gerald A. Weisenfluh, Robert E. Andrews, John K. Hiett, James C. Cobb, Richard E. Sergeant

Report of Investigations--KGS

Available resources for the Fire Clay coal were calculated for a 15-quadrangle area in the Eastern Kentucky Coal Field. Original coal resources were estimated to be 1.8 billion tons (BT). Coal mined or lost in mining was estimated at 449 million tons (MT), leaving 1.3 BT of remaining Fire Clay resources in the study area. Of the remaining resources, 400 MT is restricted from mining, primarily because the coal is less than 28 in. thick, normally considered too thin to mine underground using present technology. The total coal available for mining in the study area is 911 MT, or 52 …


Geology Of The Fire Clay Coal In Part Of The Eastern Kentucky Coal Field, Stephen F. Greb, John K. Hiett, Gerald A. Weisenfluh, Robert E. Andrews, Richard E. Sergeant Jan 1999

Geology Of The Fire Clay Coal In Part Of The Eastern Kentucky Coal Field, Stephen F. Greb, John K. Hiett, Gerald A. Weisenfluh, Robert E. Andrews, Richard E. Sergeant

Report of Investigations--KGS

Coal beds mined in Kentucky often are not laterally continuous in thickness, quality, or roof condition. Regional and local variation is common. Because thickness, quality, and roof conditions are the result of geologic processes that were active when the coal was deposited as a peat swamp, a better understanding of the relationships between geology and major coal resources can aid in identifying geologic trends, which can be extrapolated beyond areas of present mining. The focus of this study is on the Fire Clay (Hazard No. 4) coal, one of the leading producers in the Eastern Kentucky Coal Field with 20 …

Hydrogeology And Ground-Water Monitoring Of Coal-Ash Disposal Sites In A Karst Terrane Near Burnside, South-Central Kentucky, Shelley Minns Hutcheson, Lyle V. A. Sendlein, James S. Dinger, James C. Currens, Arsin M. Sahba

Report of Investigations--KGS

The effects of two coal-ash disposal facilities on ground-water quality at the John Sherman Cooper Power Plant, located in a karst region of south-central Kentucky, were evaluated using dye traces in springs. Springs were used for monitoring rather than wells, because in a karst terrane wells are unlikely to intercept individual conduits.

A closed-out ash pond located over a conduit-flow system discharges to three springs in the upper Salem and Warsaw Formations along Lake Cumberland. Water discharging from these downgradient springs is similar to springs unaffected by ash-disposal facilities and is a calcium-bicarbonate type. No constituent concentrations found in this …


Fresh-Water Aquifer In The Knox Group (Cambrian–Ordovician) Of Central Kentucky, James A. Kipp Jan 1997

Fresh-Water Aquifer In The Knox Group (Cambrian–Ordovician) Of Central Kentucky, James A. Kipp

Report of Investigations--KGS

Fresh water can be found in Cambrian and Ordovician carbonate rocks of the Knox Group in central Kentucky. The top of the aquifer is as much as 300 ft above mean sea level (m.s.l.) on the crest of the Cincinnati Arch, but descends off the flanks of the arch. Water is normally found in the upper 100 to 250 ft of the Knox, primarily in secondary porosity apparently associated with the unconformity at the top of the unit. Knox wells commonly exceed 750 ft in total depth, but because the aquifer is artesian, water rises to an elevation of about …

Sand And Gravel Resources Along The Ohio River Valley In Boone, Gallatin, And Carroll Counties, Kentucky, Eugene J. Amaral

Report of Investigations--KGS

Glacial outwash sand and gravel from three northern Kentucky counties in the Ohio River Valley have been analyzed in order to characterize their particle size, composition, morphology, and surface alteration and to determine the geologic significance of lateral and stratigraphic variations in these sediment properties. The late Wisconsinan-age deposits, actively mined in terraces along the Ohio River, are composed of moderately sorted sand and a poorly sorted, bimodal mixture of sand and gravel. A systematic pattern of regional grain-size variation was found to be associated with the confluence of the Great Miami River, a major meltwater sluiceway entering the Ohio …


Flooding Of The Sinking Creek Karst Area In Jessamine And Woodford Counties, Kentucky, James C. Currens, C. Douglas R. Graham Jan 1993

Flooding Of The Sinking Creek Karst Area In Jessamine And Woodford Counties, Kentucky, James C. Currens, C. Douglas R. Graham

Report of Investigations--KGS

Tashamingo Subdivision in Sinking Creek Karst Valley, a tributary of the Garretts Spring Drainage Basin in Jessamine and Woodford Counties, Kentucky, was flooded in February 1989. To determine the cause of flooding, the boundary of the ground-water basin was mapped, discharge data were measured to determine intake capacity of swallow holes, and hydrologic modeling of the basin was conducted. Swallow-hole capacity was determined to be limited by the hydraulic parameters of the conduit, rather than by obstruction by trash. Flooding from a precipitation event is more likely, and will be higher, when antecedent soil moisture conditions in the watershed are …

Report of Investigations--KGS

By the year 2010, the Star Fire mining operation in Knott, Breathitt, and Perry Counties in eastern Kentucky, which uses mountaintop-removal and hollow-fill mining techniques, will have created approximately 5,000 acres of gently rolling terrain that could support alternative land uses. The present research is centered on approximately 1,000 acres of spoil created since mining began in 1981. An aquifer fed by both ground and surface water will be created within the spoil. Spoil-handling techniques such as cast blasting, dragline placement, end dumping by trucks, and surface grading have created porous coarse-rock zones within the spoil through which ground water …


Mineralization And Hydrocarbon Emplacement In The Cambrian-Ordovician Mascot Dolomite Of The Knox Group In South-Central Kentucky, Warren H. Anderson Jan 1991

Mineralization And Hydrocarbon Emplacement In The Cambrian-Ordovician Mascot Dolomite Of The Knox Group In South-Central Kentucky, Warren H. Anderson

Report of Investigations--KGS

The Mascot Dolomite, the upper unit of the Cambrian-Ordovician Knox Group, is a major host for Mississippi Valley-type ore deposits and petroleum in south-central Kentucky. The Mascot was deposited on a broad, shallow platform that exhibited unusually uniform conditions of deposition, ranging from supratidal to shallow subtidal environments. The formation has a complex diagenetic history, including several stages of dolomitization, silicification, solution, and brecciation. Diagenesis and, to some extent, deposition were influenced by Early Ordovician tectonic activity. Tectonic activity influenced development of a regional unconformity during Middle Ordovician time. Evidence of this tectonic activity includes up to 300 feet of …
