Download or read book Subsurface Steam Sampling in Geysers Wells written by and published by . This book was released on 1997 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new downhole sampling tool has been built for use in steam wells at The Geysers geothermal reservoir. The tool condenses specimens into an initially evacuated vessel that is opened down hole at the direction of an on-board computer. The tool makes a temperature log of the well as it is deployed, and the pressure and temperature of collected specimens are monitored for diagnostic purposes. Initial tests were encouraging, and the Department of Energy has funded an expanded effort that includes data gathering needed to develop a three-dimensional model of The Geysers geochemical environment. Collected data will be useful for understanding the origins of hydrogen chloride and non-condensable gases in the steam, as well as tracking the effect of injection on the composition of produced steam. Interested parties are invited to observe the work and to join the program.

Download or read book Applying Flowrate Type Curves to Geysers Steam Wells written by and published by . This book was released on 1987 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Dimensionless flowrate type curves were applied to steam wells at The Geysers in an attempt to quantify reservoir properties and to predict flowrate decline. Although data scatter was a problem, the flowrate data was smoothed by a normalization routine based on the back-pressure equation and the wells were modeled by dimensionless functions for a radial system with a infinite or finite outer boundary and a constant pressure inner boundary (composite analytical-empirical type curve). The "match" resulted in a unique D{sub i} value for use in Arps' equation and a permeability-thickness product (kh) comparable to kh values obtained from pressure buildup analysis. Finally, it was shown that at least four years of data is required to obtain a unique b value. 2 tabs., 12 refs., 12 figs.

Book excerpt: Handbook of Environmental Isotope Geochemistry, Volume 1: The Terrestrial Environment, A focuses on isotope hydrology and aqueous geochemistry, as well as an overview of carbon, sulfur, and nitrogen isotopes in terrestrial systems. The selection first elaborates on the isotopes of hydrogen and oxygen in precipitation, carbon-14 in hydrogeological studies, and environmental isotopes in groundwater hydrology. Concerns cover groundwater dating, mechanism of salinization, groundwater recharge, models of the isotope fractionation during evaporation and condensation of water in the atmosphere, and stable isotope distribution in atmospheric waters. The book then examines environmental isotopes in ice and snow, isotopic evidence on environments of geothermal systems, and sulfur and oxygen isotopes in aqueous sulfur compounds. Discussions focus on geochemistry and isotope distribution of aqueous sulfur compounds, isotopic dating of geothermal waters, origin of chemical constituents, geothermometry, isotope distribution during the reduction of a temperate snow cover, and snow and ice isotope hydrology. The manuscript explores environmental isotopes as environmental and climatological indicators, sulfur isotopes in the environment, nitrogen-15 in the natural environment, and the isotopic composition of reduced organic carbon. The selection is a valuable reference for researchers interested in isotope geochemistry.

Available in PDF, EPUB and Kindle. Book excerpt: Recently developed pressure-temperature-spinner (PTS) tools are used to collect reliable downhole measurements in geothermal systems, such as at The Geysers. PTS surveys in several flowing Geysers steam wells were used to quantify steam entry location and magnitude, wellbore heat loss, pressure drop due to friction, thermodynamic properties of the steam, and maximum rock temperature. Interwell cross flow/interference was identified in one well. Finally, a single-phase saturated steam wellbore model used to compare calculated to measured downhole values, was found to adequately predict the flowing pressure versus depth curves in vapor filled holes.
Download or read book Pressure Temperature Spinner Survey in a Well at the Geysers written by and published by . This book was released on 1986 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents results from a flowing pressure-temperature-spinner log run in a well drilled by GEO Operator Corporation (GEOOC) at The Geysers. Analysis and interpretation of the log data are also presented. The data indicated superheated steam with a temperature of 600 F (316 C) and an enthalpy of 1316 BTU/lbm (725 cal/gm) entered the wellbore below 8000 feet (2438 meters). This temperature and enthalpy is much higher than most Geysers steam wells which produce steam at or below 475 F (246 C) and 1240 BTU/lbm (683 CALIgm). The high temperature and enthalpy are even more puzzling since static pressure and temperature measurements conducted with Kuster type instruments six months later, indicate a ''normal'' vapor-dominated system existing at 475 F (246 C) and 500 psia (35 Kg/cm2). Conceptual reservoir models which can explain these unusual thermodynamic conditions are presented.
