Description: This volume contains reservoir, production, and project data for target reservoirs thermally recoverable by steam drive which are equal to or greater than 2500 feet deep and contain heavy oil in the 8 to 25/sup 0/ API gravity range. Data were collected from three source types: hands-on (A), once-removed (B), and twice-removed (C). In all cases, data were sought depicting and characterizing individual reservoirs as opposed to data covering an entire field with more than one producing interval or… more

Depth to and Concentrations of Water in Large Bodies of Silicic Magma. Progress Report, July 1, 1982-June 30, 1983

Description: Large bodies of silicic magma are potential sources of geothermal energy and ore. They also pose threats of catastrophic eruptions. The depths of such bodies are related to their economic potential and probably to their eruption mechanisms. The concentrations of water in the magmas are important for their eruptive and dynamical behavior and for the development of ores. Estimates of viscosity and density of melt require knowledge of concentration of water. The concentration of water in melt befo… more

Behavior of the thermal skin of cooling pond waters subjected to moderate wind speeds

Description: The temperature difference ..delta..T/sub delta/ across the partially laminar skin of water on the surface of a water body is determined by the total heat transfer Q through the skin, the wind speed u, and the mean temperature T/sub delta/ of the skin. Systematic measurements of these variables were made over a wide range of conditions at a cooling pond in northeastern Illinois. Waves were present in all cases; the wind speeds were u = 2.5 to 7.0 m s/sup -1/ at a height of 1 m and water tempera… more

Laser-induced shock waves effects in materials

Description: A review of the effects of pressure pulses on materials is presented with an orientation toward laser-induced shock wave effects in biological tissue. The behavior is first discussed for small amplitudes, namely sound waves, since many important features in this region are also applicable at large amplitudes. The generation of pressure pulses by lasers is discussed along with amplitudes. The origin and characteristic properties of shock waves are discussed along with the different types of effe… more

Preduction of transport properties of gases using classical nonspherical models

Description: The general formulation of the classical kinetic theory, which is needed to predict transport properties of gases in situations where the hydrodynamic equations are valid, is reviewed. A rigid convex model of tetrahedral symmetry is used to predict the Senftleben-Beenakker effect of a static magnetic field on the thermal conductivity and viscosity of pure CH/sub 4/, CD/sub 4/ and CF/sub 4/. The parameters of the model are optimized and are found to assume physically reasonable values. The calcu… more

Hydrogen bonding in asphaltenes and coal liquids. Quarterly report, November 1, 1980-January 31, 1981

Description: The aging characteristics of 30/70 (wt. %) blend of SRC I and SRC II and of a SRC II Middle Distillate (boiling point range 450 to 565/sup 0/K), have been studied. Viscometric, electron spin resonance, ultimate analysis, solvent separations, gel permeation chromatography, and 600-MHz measurements have been used to monitor the aging properties of the SRC liquids under various conditions. The viscosity of the blend increases significantly in ten days with oxygen bubbling at 335/sup 0/K. However, … more

Heavy oil reservoirs recoverable by thermal technology. Annual report

Description: The purpose of this study was to compile data on reservoirs that contain heavy oil in the 8 to 25/sup 0/ API gravity range, contain at least ten million barrels of oil currently in place, and are non-carbonate in lithology. The reservoirs within these constraints were then analyzed in light of applicable recovery technology, either steam-drive or in situ combustion, and then ranked hierarchically as candidate reservoirs. The study is presented in three volumes. Volume I presents the project bac… more

Mineral matter effects in coal liquefaction. 1. Autoclave screening study. [10 refs]

Description: Several high-volatile bituminous coals were hydroliquefied, in a one-liter autoclave, at a temperature of 430/sup 0/C, initial (cold) H/sub 2/ pressure of 1000 psig, and residence time of 30 min. All experiments were carried out in creosote oil as the solvent, at a solvent: coal ratio of 2.3: 1. The feed coals ranged in mineral content from 21 percent to 5 percent, and in sulfur content from over 6 percent to under 1 percent. The coals had similar maceral distributions, and most were vitrinite-… more

Variations in volatiles in magma bodies based on studies of melt inclusions

Description: Knowledge of volatile concentrations in magmas are important in the prediction of explosive volcanism, and contribute to the understanding of the carbon dioxide budget of the atmosphere. Some important variables that are controlled by volatiles are: crystallization temperature of phases, composition of liquids minimum, and viscosity. Volatiles are also catalysts for reactions.

Numerical calculation of thermal convection in porous media in two dimensions with applications to nuclear repository design

Description: Thermal convection induced by nuclear waste heating could be an important mechanism in the transport of radioactive nuclides to the biosphere. A computer code HP2D was developed to calculate this effect. The code calculates transient and steady state heat and fluid flow in porous media. It allows for anisotropy of hydraulic conductivities, temperature dependent fluid density and viscosity. A heat source and a variety of temperature and flow boundary conditions can be easily employed. The code s… more
