Technique for characterizing crevice corrosion under hydrothermal conditions

Description: The current/potential results show that the crevice corrosion incubation period for a Grade-12 titanium crevice formed between two Teflon plates is about two days at 150/sup 0/C. Optical and SEM observations show that the corrosion starts as isolated pitting which spreads along the surface as shallow pits. The corrosion conditions change significantly as the TiO/sub 2/ corrosion product fills the crevice, and the rate of corrosion may be greatly reduced after several days. The rate of crevice c… more

Definition of the waste package environment for a repository located in salt

Description: The expected environmental conditions for emplaced waste packages in a salt repository are simulated in the materials testing program to evaluate performance. Synthetic brines, based on the analyses of actual brines (both intrusion and inclusion), are used for corrosion and leach testing. Elevated temperatures (to 150/sup 0/C) and radiation fields of up to 10/sup 3/ rad/h are employed as conservative conditions to bracket expected performance and provide data for worst case scenarios. Obtaining… more

Generating capacity of the Heber geothermal field, California

Description: Using numerical simulation techniques and the radial model developed for the study of the natural state of the Heber field (Lippmann and Bodvarsson, 1983b), the response of this geothermal system to exploitation is analyzed. In this study the generation rate in the field is allowed to build up over a period of 10 years; after that, 30 years of constant power production is assumed. Full (100%) injection of the spent brines is considered, the fluids being injected 2250 m (near injection) or 4250 … more

Stress corrosion of ASTM Grade-2 and Grade-12 titanium in simulated rock salt brines at 83/sup 0/C

Description: Slow-strain-rate tests have been conducted on Grade-2 and Grade-12 titanium in simulated rock salt brines at 83/sup 0/C. Although neither metal shows stress corrosion cracking, total elongation and reduction in area show some decrease. Optical and SEM results are discussed to elucidate the fracture mechanism.

West Hackberry Strategic Petroleum Reserve site brine-disposal monitoring, Year I report. Volume 3. Biological oceanography. Final report

Description: The Department of Energy's Strategic Petroleum Reserve Program began discharging brine into the Gulf of Mexico from its West Hackberry site near Cameron, Louisiana in May 1981. The brine originates from underground salt domes being leached with water from the Intracoastal Waterway, making available vast underground storage caverns for crude oil. The effects of brine discharge on aquatic organisms are presented in this volume. The topics covered are: benthos; nekton; phytoplankton; zooplankton; … more

Salton Sea Geothermal Field, California, as a near-field natural analog of a radioactive waste repository in salt

Description: Since high concentrations of radionuclides and high temperatures are not normally encountered in salt domes or beds, finding an exact geologic analog of expected near-field conditions in a mined nuclear waste repository in salt will be difficult. The Salton Sea Geothermal Field, however, provides an opportunity to investigate the migration and retardation of naturally occurring U, Th, Ra, Cs, Sr and other elements in hot brines which have been moving through clay-rich sedimentary rocks for up t… more

Disposal of Flashed Brine Dosed with CaCO{sub3} Scale Inhibitor: What Happens When the Inhibitor is Exhausted?

Description: A freshly flashed geothermal liquid, previously dosed with inhibitor and super-saturated with calcite was injected into another well where it displaced an unflashed counterpart of itself around the wellbore. Back-production of the injectate, and subsequently the native fluid, has yielded data for the rate that a scale inhibitor is degraded after injection. The circumstance also displays a novel mechanism whereby two fluids that do not physically mix never the less reactive with one another thro… more

Session 2: Review of the 500 KW Direct Contact Geothermal Plant at East Mesa

Description: The concept of a binary power cycle utilizing direct contact heat exchangers was first proposed by Jacobs and Boehm in 1973 for use with geothermal brines. This concept was proposed primarily to overcome difficulties associated with the fouling and scaling nature of many moderate temperature brines. However, thermodynamic analyses and subsequent economic analyses clearly pointed to possible economic advantages over conventional binary cycles even with non-fouling, non-scaling brines. For a dire… more

Session 11: Geopressured Geothermal Well Testing

Description: Extended-term tests of Gulf Coast geopressured brine wells have provided some surprising information. These wells produce small, but ever increasing, quantities of aromatic condensate. The wells suffer both scale and corrosion problems that appear to be amenable to simple control measures. Long-term production will probably not require exotic metallurgy. Fluid disposal at high flow rates is a well-understood process. Reservoir rock mechanics are indicating much larger fluid recoveries than prev… more

Development of a high temperature pH electrode for geothermal fluids. Final report, Task III and year end summary

Description: This report summarizes work done to demonstrate the applicability of a stabilized zirconia pH sensor to high temperature measurements on brines containing as much as 20 weight percent NaCl and 100 ppM hydrogen sulfide. Throughout the program stable operation was achieved, and measured pH values were in good agreement with calculated values. Differences were generally less than 0.5 pH unit at 285/sup 0/C, and it is not yet certain whether the discrepancies are associated with the measured or cal… more

Comparison Between Two Lysholm Engines

Description: The University of California at Berkeley (UCB) and the Jet Propulsion Laboratory (JPL) both have been working on the Lysholm engine as an expander of two phase geothermal brine. The sizes of the machines, (The machine at UCB is rated at 25 kW, and the machine that JPL tested is rated at 1MW) as well as the approaches, are different. Here, some comparisons are made in order to clarify the direction in which future efforts should be conducted.
