High-Volume Oil Discovery In Clinton County, Kentucky, Terence Hamilton-Smith, Brandon C. Nuttall, Patrick J. Gooding, Dan Walker, James A. Drahovzal Jan 1990

High-Volume Oil Discovery In Clinton County, Kentucky, Terence Hamilton-Smith, Brandon C. Nuttall, Patrick J. Gooding, Dan Walker, James A. Drahovzal

Information Circular--KGS

The Syndicated Options Limited of Austria No. 9372 Ferguson Brothers well, located in southern Clinton County, Kentucky, has recently produced oil at reported initial rates of 400 to 130 barrels per hour. Cumulative production for the first 8 weeks of flow following discovery on September 25, 1990, is reported to be nearly 150,000 barrels. The well is the result of deepening a previously abandoned well. Production is from the Middle Ordovician High Bridge Group (equivalent to the Stones River Group of Tennessee) at a depth of 1,008 feet. The reservoir is apparently a fractured carbonate rock, and the fracturing is …


Use Of Limestone, Lime, And Dolomite For So2 Emission Control In Kentucky, Garland R. Dever Jr. Jan 1990

Use Of Limestone, Lime, And Dolomite For So2 Emission Control In Kentucky, Garland R. Dever Jr.

Information Circular--KGS

Flue-gas desulfurization and atmospheric fluidized-bed combustion systems for sulfur dioxide (SO2) emission control have been installed at 13 coal- and gas-fired plants and one research laboratory in Kentucky. Limestone, lime, and dolomite are the principal SO2 sorbents used in these systems.

Nine coal-fired, electricity-generating plants in the State have installed wet-scrubbing systems for flue-gas desulfurization. Lime-based scrubbers are using Thiosorbic® lime, produced from the Camp Nelson Limestone (Ordovician) of north-central Kentucky, and carbide lime, a byproduct from the manufacture of acetylene in Louisville. Limestone-based scrubbing systems at three of the plants have used stone from the Warsaw, …

Regionalization Of Flood Data Using Probability Distributions And Their Parameters, Nageshwar Rao Bhaskar, Carol Alf O'Connor, Harold Andrew Myers, William Paul Puckett

KWRRI Research Reports

The U. S. Geological survey recently used the method of residuals to delineate seven flood regions for the State of Kentucky. As an alternative approach, the FASTCLUS clustering procedure of the Statistical Analysis system (SAS) is used in this study to delineate five to six cluster regions in conjunction with statistical properties of the AMF series, like the coefficient of variation as estimated using method of L-moments, LCV, the parameters of the EVl and GEV flood frequency distributions, and the specific mean annual flood, QSP. For both cluster and USGS flood regions, regionalized flood frequency growth curves are developed and …

Development Of Dynamic Non-Hortonian Watershed Models For Steeply Sloping Forested Watersheds: Application To Eastern Kentucky, Lindell E. Ormsbee, Abdul Q. Khan Aug 1987

Development Of Dynamic Non-Hortonian Watershed Models For Steeply Sloping Forested Watersheds: Application To Eastern Kentucky, Lindell E. Ormsbee, Abdul Q. Khan

KWRRI Research Reports

A comprehensive conceptual watershed model is developed to simulate the hydrologic response of steeply sloping forested watersheds. Two non-Hortonian and two Hortonian models were first tested with data from selected watersheds in West Virginia and eastern Kentucky in order to understand the different mechanisms of flow responsible for storm hydrograph generation in this type of watersheds. The two non-Hortonian models tested were the kinematic storage model (Sloan et al. 1983) and the saturation deficit model (Beven and Wood, 1983). Both models were unable to adequately reproduce the observed hydrographs in the four forested watersheds considered in this research. The two …

Slack-Water Deposits And The Magnitude And Frequency Of Flash Floods, Eastern Kentucky, Russell G. Shepherd, Lisa K. Bienkowski Nov 1986

Slack-Water Deposits And The Magnitude And Frequency Of Flash Floods, Eastern Kentucky, Russell G. Shepherd, Lisa K. Bienkowski

KWRRI Research Reports

The potential for predicting flood magnitude and frequency using sediments deposited in backwater areas during flash floods was investigated on the Cumberland Plateau of eastern Kentucky, a region n9torious for flash flooding. Slack-water deposits are abundant in the area at tributary mouths and bedrock channel expansions. They are identifiable on geologic quandrangle maps, and are locally good potential indicators of maximum flood-crest elevations. However, in this humid region, flash floods could not be distinguished from non-flash floods using slack-water sedimentology.

The results from the slack-water deposits studied indicate that they offer limited potential for predicting flash floods because 1) intense …

A Model For Assessing The Visual Resources Of River Basins As An Aid To Making Landuse Planning Decisions, Thomas J. Nieman, Diane S. Meshako, David Walters, Molly M. Davis, Cindy C. Elliot

KWRRI Research Reports

The visual quality of a river basin and its associated properties can be identified, evaluated and integrated into the landscape planning process. The model developed provides a quantitative methodology for determining visual quality on the basis of available Geographic Information System factors. These factors are utilized to develop the preference attributes, COLOR, FORM, TEXTURE and LINE, which are associated with the assessment of visual quality. The preference attributes are then combined through a decision making process into a continuum of DISTINCTIVE, GOOD, AVERAGE and MINIMAL visual quality and is expressed digitally in map format. By providing visual quality information in …

Depositional Environments And Petrology Of The Felix Coal Interval (Eocene), Powder River Basin, Wyoming, Peter D. Warwick Jan 1985

Depositional Environments And Petrology Of The Felix Coal Interval (Eocene), Powder River Basin, Wyoming, Peter D. Warwick

Theses and Dissertations--Earth and Environmental Sciences

A study of a 250 ft. (76.2 m) stratigraphic interval that includes the Eocene-age Felix coal of the Wasatch Formation was undertaken in the Powder River Basin of Wyoming to establish a depositional model based on the interrelations of coal-seam geometry, coal maceral composition, and spatial distribution of adjoining rocks. Regional cross sections and maps of major rock bodies were prepared from 147 measured stratigraphic sections and 56 geophysical logs. Trends in maceral and chemical properties within the Felix coal were identified from petrographic and geochemical analyses of 72 coal channel samples. The combined data sets indicate that the thickest …

Barite Deposits Of Kentucky, Warren H. Anderson, Robert D. Trace, Preston Mcgrain Jan 1982

Barite Deposits Of Kentucky, Warren H. Anderson, Robert D. Trace, Preston Mcgrain

Bulletin--KGS

Barite deposits are known to be present in 23 counties in Kentucky, principally in the Central Kentucky Mineral District and the Western Kentucky Fluorspar District. Field investigations and a literature search indicate the presence of barite at more than 170 outcrops, prospects, and abandoned mines.

Geologically, most of the Kentucky barite deposits are classified as vein or residual deposits. The vein deposits are cavity and breccia fills along faults and joints, commonly in limestone. Residual deposits occur in an unconsolidated clayey residuum formed by weathering of preexisting vein or breccia deposits. Most deposits are mixed ores commonly containing calcite, fluorite, …


Investigation Of Subsurface Tar-Sand Deposits In Western Kentucky, David A. Williams, Martin C. Noger, Patrick J. Gooding Jan 1982

Investigation Of Subsurface Tar-Sand Deposits In Western Kentucky, David A. Williams, Martin C. Noger, Patrick J. Gooding

Information Circular--KGS

Tar sands (also referred to as asphaltic sandstones, heavy-oil deposits, or bitumen-impregnated sandstones) in western Kentucky have been recognized as a potential mineral resource for over l 00 years. Past commercial development has been restricted largely to use as paving material. However, because of the ever-expanding demands for energy, these deposits have become the subject of increasing interest as a potential petroleum resource.

Previous studies have provided estimates of the potential resources of shallow mineable tar-sand deposits; these investigations have concentrated on the outcrop areas where tar sands are present at or near the surface. Data on subsurface deposits have …

Study of springs and cave streams has shown that heavy metal-rich effluent from a wastewater treatment plant can be traced to Hidden River Cave (beneath the city of Horse Cave) and thence 4 to 5 miles north to a group of 39 springs at 14 locations along a 5-mile reach of Green River. Nickel, chromium, copper and zinc in these effluent-bearing springs are in concentrations of as much as 30 times greater than other springs upstream and downstream from this reach, 20 times greater than the Green River, and 60 times greater than in shallow domestic wells between Horse Cave …


Analysis Of Unsteady Flow Toward Artesian Wells By Three-Dimensional Finite Elements, Yang H. Huang, Shen-Jyh Wu Aug 1974

Analysis Of Unsteady Flow Toward Artesian Wells By Three-Dimensional Finite Elements, Yang H. Huang, Shen-Jyh Wu

KWRRI Research Reports

A three-dimensional finite element computer program was developed for analyzing unsteady flow toward artesian wells. The program is designed especially for determining the drawdown around an artesian well penetrating fully or partially a nonhomogeneous and anisotropic aquifer of irregular shape and cross section. It can also be used as a general program for aquifer simulation and evaluation. A major advantage of the program lies in the minimum amount of input data required. By assuming the top and bottom boundaries of the aquifer as two arbitrary planes, the aquifer will be divided into six- or eight-node elements, and their nodal coordinates …
