Preliminary state-of-the-art survey: mining techniques for salt and other rock types

This is a systematic review of the state-of-the-art of underground mining and excavation technology in the U.S. as applied to salt, limestone, shale, and granite. Chapter 2 covers the basic characteristics of these rock types, the most frequently used underground mining methods, shaft and slope entry construction, equipment, and safety and productivity data. Chapters 3 and 4 summarize underground salt and limestone mining in the U.S. Chapter 5 shows that large amounts of thick shale exist in the U.S., but little is mined. Chapter 6 discusses underground excavations into granite-type rocks. Suggestions are given in the last chapter for further study. (DLC)

Energy supply and demand in Texas for the period 1950--1973. Project S/D-1, final report (open access)

Energy supply and demand in Texas for the period 1950--1973. Project S/D-1, final report

The energy production and consumption data show a pattern of increased reliance on crude oil and natural gas as primary energy sources. Early production of coal diminished as natural gas became readily available. Hydropower has been developed at several multipurpose dam sites, but is less than one percent of the total Texas electric power capacity. Power plants have been fired primarily with natural gas, but recent developments have caused the substitution of fuel oil, and plans for new capacity include both nuclear and coal fired units. The trends in consumption of energy show several important factors in the economics of energy. Residential use of electricity has grown rapidly and was accompanied by large increases in per capita home heating and air conditioning and electrical appliances, and by a declining real price of electricity. Texas consumers also greatly increased their per capita use of gasoline during the 1950-1973 period with increases in the per capita ownership of automobiles and near constant real prices for gasoline. Both trends (electricity and gasoline use per capita) grew at a faster rate in Texas than for the U.S. The concentration of petroleum refining and chemical manufacturing industries in Texas has made these industries and the …

Gulf Coast Programmatic Environmental Assessment Geothermal Well Testing: The Frio Formation of Texas and Louisiana (open access)

Gulf Coast Programmatic Environmental Assessment Geothermal Well Testing: The Frio Formation of Texas and Louisiana

In accordance with the requirements of 10 CFR Part 711, environmental assessments are being prepared for significant activities and individual projects of the Division of Geothermal Energy (DGE) of the Energy Research and Development Administration (ERDA). This environmental assessment of geopressure well testing addresses, on a regional basis, the expected activities, affected environments, and possible impacts in a broad sense. The specific part of the program addressed by this environmental assessment is geothermal well testing by the take-over of one or more unsuccessful oil wells before the drilling rig is removed and completion of drilling into the geopressured zone. Along the Texas and Louisiana Gulf Coast (Plate 1 and Overlay) water at high temperatures and high pressures is trapped within Gulf basin sediments. The water is confined within or below essentially impermeable shale sequences and carries most or all of the overburden pressure. Such zones are referred to as geopressured strata. These fluids and sediments are heated to abnormally high temperatures (up to 260 C) and may provide potential reservoirs for economical production of geothermal energy. The obvious need in resource development is to assess the resource. Ongoing studies to define large-sand-volume reservoirs will ultimately define optimum sites for drilling …

Briefing book on the energy situation in New England (open access)

Briefing book on the energy situation in New England

This briefing book is designed to give a concise overview of the facts of the energy situation in New England and of attitudes within the region towards current energy issues. Many of the central problems of U.S. energy policy are manifested in the region in a magnified form. The region entered the period of energy shortages and increasing prices in an economically declining condition. Energy prices were already high in 1970, 30% higher than the rest of the country; the difference increased to 38% by 1974. With essentially no indigenous energy resources, New England is an energy-importing region. For various reasons it is also more dependent on petroleum than other regions of the country and, at the same time, distant from domestic petroleum-producing regions. The result is that over 60% of the fuels it consumes is imported from abroad. Although the future supply of energy to the region is critically dependent on energy-resource policies, policies related for example to coal and oil shale development, the region's concerns cluster around policies and technologies that are perceived to have a more direct impact on its energy welfare. Thus, energy conservation, solar energy, nuclear power, offshore oil development and, in general, the price …

Environmental Assessment: Geothermal Energy Geopressure Subprogram. Gulf Coast Well Testing Activity, Frio Formation, Texas and Louisiana

This Environmental Assessment (EA) has been prepared to provide the environmental input into the Division of Geothermal Energy's decisions to expand the geothermal well testing activities to include sites in the Frio Formation of Texas and Louisiana. It is proposed that drilling rigs be leased before they are removed from sites in the formation where drilling for gas or oil exploration has been unsuccessful and that the rigs be used to complete the drilling into the geopressured zone for resource exploration. This EA addresses, on a regional basis, the expected activities, affected environment, and the possible impacts in a broad sense as they apply to the Gulf Coast well testing activity of the Geothermal Energy Geopressure Subprogram of the Department of Energy. Along the Texas and Louisiana Gulf Coast (Plate 1 and Overlay, Atlas) water at high temperatures and high pressures is trapped within Gulf basin sediments.

Analysis of US underground thin seam mining potential. Volume 1. Text. Final technical report, December 1978. [In thin seams]

An analysis of the potential for US underground thin seam (< 28'') coal mining is undertaken to provide basic information for use in making a decision on further thin seam mining equipment development. The characteristics of the present low seam mines and their mining methods are determined, in order to establish baseline data against which changes in mine characteristics can be monitored as a function of time. A detailed data base of thin seam coal resources is developed through a quantitative and qualitative analysis at the bed, county and state level. By establishing present and future coal demand and relating demand to production and resources, the market for thin seam coal has been identified. No thin seam coal demand of significance is forecast before the year 2000. Current uncertainty as to coal's future does not permit market forecasts beyond the year 2000 with a sufficient level of reliability.

Bibliography of the Geology of the Columbia Basin and Surrounding Areas of Washington (open access)

Bibliography of the Geology of the Columbia Basin and Surrounding Areas of Washington

In the fall of 1977, the Washington State Department of Natural Resources, Division of Geology and Earth Resources (WDGER), entered into a contract with the US Department of Energy, administered by Rockwell Hanford Operations (Rockwell) in Richland, Washington, as a principal contributor to a geologic study of feasibility of storing radioactive waste within Columbia River basalt. WDGER's responsibility was the production of this bibliography and a reconnaissance geologic map of the sediments overlying the Columbia River Basalt Group in the State of Washington. This bibliography is a compilation of all known published, unpublished, and open-file references dealing with geology and geophysics of the Columbia Basin of eastern Washington. The citations were obtained primarily from the WDGER and Washington State libraries; the Geo-Ref bibliographic system was also utilized. Because the WDGER portion of the study included preparation of a reconnaissance geologic map of surficial deposits in the Columbia Basin, available references dealing with this subject have been annotated. Many abstracts in the annotated section are quotations and have been copied directly from their respective publications.

Federal income taxation of the U. S. petroleum industry and the depletion of domestic reserves. Final report (open access)

Federal income taxation of the U. S. petroleum industry and the depletion of domestic reserves. Final report

This paper models in a dynamic framework the production activities of the United States petroleum industry in an attempt to measure the effects of the federal income tax on reserve depletion. This model incorporates general corporate taxes, including the capital subsidies, excess depreciation and the investment tax credit, and taxes unique to the industry: drilling subsidies and percentage depletion. Because corporate response to tax incentives depends on market power and behavior, three behavioral assumptions are tested for consistency with the 1960 to 1974 data period before the tax policies are simulated. These assumptions are perfect competition, profit monopoly, and sales monopoly. The tax policies simulated at the end of this paper present six possible alternatives for future petroleum industry taxation. Sales monopoly is selected as the behavioral assumption that best describes petroleum industry behavior. Tax simulations under sales monopoly reveal that historical income tax policies have kept oil prices artificially low, stimulating (subsidizing) reserve depletion.

Use of solar energy in the production of channel catfish. Final report (open access)

Use of solar energy in the production of channel catfish. Final report

No catfish are grown commercially in eastern Kentucky due primarily to a growing season approximately three weeks too short to provide the minimum 180 day feeding season. This research project was designed to test the feasibility of using solar energy to heat pond water enough to lengthen the feeding season the required number of days. The procedure involved the heating of a small starter pond by covering it with a solar swimming pool cover. Fingerling catfish were stocked in the small pond in early April and transferred to a larger rearing pond in May when water temperatures in the larger pond reached 65/sup 0/ F. Oxygen levels were maintained at acceptable levels in the covered pond by frequent aeration. Water quality resulting from a prolonged spring drought and run-off from a pasture fertilized by chicken manure seriously affected the project. Other significant problems encountered included algae build-up and the accumulation ammonia and carbon dioxide in the water. Losses to fungus infection was the most serious problem encountered. Approximately 30 percent of the fingerlings died from this cause while in the small covered pond. After the fish were transferred to the large rearing pond, no further unanticipated problems were encountered. From …
