An Investigation of Certain Thermodynamic and Transport Properties of Water and Water Vapor in the Critical Region

Description: An accurate knowledge of thermodynamic and transport properties of water in the critical region is required in order to analyze future power cycles, nuclear reactor configurations, and other types of heat transfer apparatus. Preliminnry investigations showed that this was rot possible with presently existing tabulations. Experimentel data from volumetric viscosity and thermal conductivity studies were therefore selected and retabulated. Smoothings of these data are described and, for the first … more

Motor Challenge Energy Matters, May 1999

Description: The May issue of Energy Matters (formerly Turning Point) features articles on motor, steam, and compressed air systems management. One article explains how chemical treatment can improve boiler system efficiency; another discusses the importance of data logging to assess compressed air system performance. A feature article describes motor system upgrades at Blue Circle Aggregates, a Georgia quarry, which resulted after a no-cost assessment by one of DOE's Industrial Assessment Centers. This iss… more

Investigation of Multiscale and Multiphase Flow, Transport and Reaction in Heavy Oil Recovery Processes

Description: In this report, the thrust areas include the following: Internal drives, vapor-liquid flows, combustion and reaction processes, fluid displacements and the effect of instabilities and heterogeneities and the flow of fluids with yield stress. These find respective applications in foamy oils, the evolution of dissolved gas, internal steam drives, the mechanics of concurrent and countercurrent vapor-liquid flows, associated with thermal methods and steam injection, such as SAGD, the in-situ combus… more

Measurement of Downhole Steam Quality and Total Energy by Optical Methods

Description: Initial steps have been taken to measure the mass of water in vapor and liquid phases downhole in a steam injection heavy oil recovery system. A suitable portion of the electromagnetic spectrum has been identified over which the presence of liquid water and vapor can be separated. This is in the near infrared and extends from ~900 nm to 1.8 µm region. A high pressure and high temperature cell has been constructed and tested for stagnant transmissions. Pitting of the optical ports due to the pre… more

Integrated modeling and field study of potential mechanisms forinduced seismicity at The Geysers Goethermal Field, California

Description: In this paper, we present progress made in a study aimed atincreasing the understanding of the relative contributions of differentmechanisms that may be causing the seismicity occurring at The Geysersgeothermal field, California. The approach we take is to integrate: (1)coupled reservoir geomechanical numerical modeling, (2) data fromrecently upgraded and expanded NCPA/Calpine/LBNL seismic arrays, and (3)tens of years of archival InSAR data from monthly satellite passes. Wehave conducted a coup… more

Computer Simulation of Single-Well Steam Assisted Gravity Drainage (SW-SAGD), SUPRI TR-119

Description: Steam assisted gravity drainage (SAGD) is an effective method of producing heavy oil and bitumen. In a typical SAGD approach, steam is injected into a horizontal well located directly above a horizontal producer. A steam chamber grows around the injection well and helps displace heated oil toward the production well. Single-well (SW) SAGD attempts to create a similar process using only one horizontal well. This may include steam injection from the toe of the horizontal well with production at t… more

Compatibility of selected ceramics with steam-methane reformer environments

Description: Conventional steam reforming of methane to synthesis gas (CO and H{sub 2}) hasa conversion efficiency of about 85%. Replacement of metal tubes in the reformer with ceramic tubes offers the potential for operation at temperatures high enough to increase the efficiency to 98-99%. However, the two candidate ceramic materials being given strongest consideration, sintered alpha Si carbide and Si carbide particulate-strengthened alumina, have been shown to react with components of the reformer enviro… more
