Evaluation of materials exposed to scale-control/nozzle-exhaust experiments at the Salton Sea geothermal field

Description: The erosion, corrosion, and stress corrosion cracking (SCC) of Ti-, Co-, Ni-, and Fe-base alloys specimens that were used in scale-control tests performed at the Salton Sea geothermal field were evaluated. Specimens were exposed to high-velocity, two-phase, 104{sup 0}C nozzle exhaust that was produced by expanding acidified hypersaline, highly mineralized brine to atmospheric pressure through converging-diverging nozzles. The exposed specimens were evaluated using surface profilometer traces, l… more

Calculation of chemical equilibrium between aqueous solution and minerals: the EQ3/6 software package. [In FORTRAN extended 4. 6 for CDC6600 and 7600]

Description: The newly developed EQ/36 software package computes equilibrium models of aqueous geochemical systems. The package contains two principal programs: EQ3 performs distribution-of-species calculations for natural water compositions; EQ6 uses the results of EQ3 to predict the consequences of heating and cooling aqueous solutions and of irreversible reaction in rock--water systems. The programs are valuable for studying such phenomena as the formation of ore bodies, scaling and plugging in geotherma… more

Near-field interactions

Description: To approach the subject of high level nuclear waste disposal in deep ocean sediments it is convenient to differentiate between processes occurring in a near field environment, that region arbitrarily defined as lying between the canister surface and the maximum extent of the 100/sup 0/C isotherm, and those which occur at lower temperatures and beyond the influence of intense radiation. A variety of considerations related to the chemistry of seawater-sediment mixtures suggests that about 200/sup… more

Preliminary seabed disposal modeling studies

Description: In order to evaluate the fluid flow, heat transfer, and ion migration rates within a postulated sub-seafloor waste disposal site, preliminary calculations and computer aided simulations were performed. A base case site description was formulated and a representative set of physical parameters were defined. This information was used in an advanced transport computer code developed by Intera Environmental Consultants to simulate, in detail, site behavior. The simulation studies were divided into … more

Standby Conservation Plan No. 1: emergency weekend gasoline sales restrictions. Economic analysis

Description: The Emergency Weekend Sales Restrictions Plan has been designed to conserve gasoline and diesel fuel normally used for social and recreational purposes. The plan would authorize the Secretary of Energy to impose restrictions on the retail sale of motor fuels during weekend hours, defined as Friday noon to Sunday midnight. Only certain types of commercial vehicles and emergency vehicles could purchase fuel during these hours. The implementation of the measure is examined relative to a baseline e… more

Continental margin atmospheric climatology and sea level (Historical setting 1974--1975)

Description: From the many continental shelf dynamics studies which have been made in the past decade, it has become increasingly apparent that a detailed analysis of continental margin waters can only be accomplished with an appreciation of the coastal meteorology. Fortunately, coastal meteorological and, in addition, coastal sea level data have been archived and thus provide coastal oceanographers with inexpensive, priceless and complimentary data sets. Past coastal sea level studies have demonstrated tha… more

Operations research and systems analysis of geopressured/geothermal resources in Louisiana. Final report for initiation project

Description: The development activities for a plan for Louisiana's participation in a Gulf Coast regional research and systems analysis activity. In developing preliminary planning scenarios heavy emphasis was placed on data describing the resource base. The scenarios are produced using a computer-oriented planning program that is code-named GEODEV. Examples of development scenarios for four fairways in Louisiana are included in an appendix. Progress in identification of decision makers, a state-wide adviso… more

Geophysical and geochemical models of the Earth's shields and rift zones

Description: This report summarizes a collection of, synthesis of, and speculation on the geophysical and geochemical models of the earth's stable shields and rift zones. Two basic crustal types, continental and oceanic, and two basic mantle types, stable and unstable, are described. It is pointed out that both the crust and upper mantle play a strongly interactive role with surface geological phenomena ranging from the occurrence of mountains, ocean trenches, oceanic and continental rifts to geographic dis… more

Subsea nuclear power generating stations for offshore oil production operations. Preliminary safety and licensing information document

Description: This document presents preliminary safety and licensing information relating to the manufacture, installation, and operation of small subsea nuclear generating stations in remote offshore locations, and the associated onshore base-site activities of reactor refueling and system refurbishment at 4-year intervals. The purpose of the proposed facilities is to provide a subsea power capability for offshore oil production operations in areas where surface conditions, water depths, or other environme… more

Geothermal development and the Salton Sea

Description: The relationship of the Salton Sea, a key element of the Imperial Valley water system, to potential geothermal development in that region is studied. The effects of direct discharge of brines into the Sea are discussed along with the use of Salton Sea water for cooling the geothermal power plants. Methods for controlling the salinity of the Salton Sea are described. (MOW)
