Coastal Effects of Offshore Energy Systems: An Assessment of Oil and Gas Systems, Deepwater Ports, and Nuclear Powerplants Off the Coasts of New Jersey and Delaware

Description: An assessment by the Office of Technology Assessment (OTA) about the effects of coastal development in the United States, specifically New Jersey and Delaware. The study looks at "the likely consequences of three energy systems for the ocean environment, the coastal environment, and the economics and patterns of life in both States during the next two decades" (p. c.1).

Dow Chemical USA Report - Appendix B

Description: The geopressured zone, assuming the presence of natural gas and high water productivity, may be used to produce economical electric power only if the water is at least 375 F or a means of conversion more efficient than flashing is found. The design and costing of a double-flash 25-megawatt plant using water at 325 F gave a capital cost of $678/kwh, a fuel cost of 63?/M Btu and a unit power cost of 46 mills/kwh. The conversion efficiency of the plant, including hydraulic turbine energy from the well head overpressure, was 10.3%. This low efficiency accounts for the high unit power cost. A one-well, 1.5-megawatt test facility will require a total capital cost of $6,661,000. Expansion of this site to a four-well, 10-megawatt pilot plant will require an additional capital expenditure of $27,843,000. The total capital cost for an independent 10-megawatt pilot plant was estimated at $31,777,000. It should be noted that the economics calculated in this report is based on industrial power plant experience. Maintenance, operating costs, and rate of return for industrial investment, as used in the calculations, do not reflect utility plant practices. The cost of power producing may compare more favorably with that of utility plants. Future power costs are projected to at least equal the costs expressed here.

The Politics of Federal Regulation of Natural Gas Producers, 1938-1968

Description: This study attempts to show that judicial review of administrative decisions has provided the greatest degree of protection for consumers during the time that natural gas has been subject to regulation by the Federal Power Commission. The first part of the investigation deals with the activities of the regulatory agency since controls were established in 1938. It continues with a discussion of the influence of consumer and producer interests on the legislative process. The contributions of the courts to policy-making is discussed in the following section. The report concludes that more protection from the political environment could be realized by placing the major responsibility for the regulatory program in the hands of the Executive branch.

An Environmental Assessment of Proposed Geothermal Well Testing in the Tigre Lagoon Oil Field, Vermilion Parish, Louisiana

Description: This report is an environmental assessment of the proposed testing of two geopressured, geothermal aquifers in central coastal Louisiana. On the basis of an analysis of the environmental setting, subsurface characteristics, and the proposed action, potential environmental impacts are determined and evaluated together with potential conflicts with federal, state, and local programs. Oil and gas wells in coastal Louisiana have penetrated a potentially productive geothermal zone of abnormally high-pressured aquifers that also yield large volumes of natural gas. To evaluate the extent to which the geothermal-geopressured water can be used as an alternative energy source and to what extent withdrawal of geopressured water can enhance gas production, it is necessary that flow rates, composition and temperature of fluids and gases, recharge characteristics, pressures, compressibilities, and other hydrodynamic and boundary conditions of the reservoir be determined by means of production tests. Tests are further necessary to evaluate and seek solutions to technological problems.

Investigation and definition of parameters associated with testing geopressure water: An Interim Report, June 1, 1975--August 31, 1976

Description: Prior to the initiation of this project, considerable literature had appeared in technical journals, particularly geological journals, describing the potential value of the energy contained in hot geopressured waters along the northern Gulf of Mexico coast. The geographic region of interest was identified as the area between Brownsville and Pensacola, approximately 200 miles wide and 750 miles long and therefore containing about 150,000 square miles of surface area. The resource was estimated as lying at depths between 5,000 and 25,000 feet. Although many descriptions of this resource had been written, not much experimental data were available regarding the actual analyses of these waters, especially the methane content. ERDA Geothermal division sponsored the current project to find out the precise analysis of the waters in the geopressured zone in a specific South Louisiana shut in gas well. This information was desired as a prelude to additional resource development projects. If the experimental results of this project were negative, doubts would be raised that there should be serious attempts at other development projects. If the results were positive (i.e., the waters were saturated with methane suggested by hydrogeological theory of this region) then ERDA would feel encouraged to proceed with larger scale projects, especially the drilling and completion of an on-purpose geopressured geothermal well. The project was funded for the purpose of dynamic testing two aquifers tapped by an existing gas well in the Tigre Lagoon field in Vermilion Parish. Some information about the characteristics of the reservoir fluid and the behavior of the reservoir under varying flow conditions was to be obtained. The analyses of the water would be run concurrently with the flow tests.
