Geologic research at the Geysers -- 1996
In response to the onset of field-wide pressure declines at The Geysers geothermal field in northern California the Department of Energy`s Geothermal Division in 1990 inaugurated sponsorship of a dedicated, multiyear research effort designed to mitigate the pressure drop and to allow steamfield operators to make more informed forecasts of steam supply and quality well into the 21st century. EGI and its predecessor, the University of Utah Research Institute, have from the onset been key participants in this important research effort. For example, utilizing fluid-inclusion and stable-isotopic methods, deciphered the field`s intricate magmatic-hydrothermal history. Hulen et al. (1991, 1992) and Hulen and Nielson (1995a) identified major textural and mineralogic differences between the productive steam reservoir and its relatively impermeable caprock.
