Available in PDF, EPUB and Kindle. Book excerpt: The Sonoma Valley area contains low-temperature geothermal resources (20 C ≤ T ≤ 90 C) having the potential for useful development. Sonoma Valley residents, local governments and institutions, private developers, and manufacturers may be able to utilize the geothermal resources as an alternate energy source. Historically, there have been at least six geothermal spring areas developed in the Sonoma Valley. Four of these (Boyes Hot Springs, Fetter's Hot Springs, Agua Caliente Springs, and the Sonoma State Hospital warm spring) lie on a linear trend extending northwestward from the City of Sonoma. Detailed geophysical surveys delineated a major fault trace along the east side of the Sonoma Valley in association with the historic geothermal areas. Other fault traces were also delineated revealing a general northwest-trending structural faulting fabric underlying the valley. Water wells located near the ''east side'' fault have relatively high boron concentrations. Geochemical evidence may suggest the ''east side'' fault presents a barrier to lateral fluid migration but is a conduit for ascending fluids. Fifteen of the twenty-nine geothermal wells or springs located from literature research or field surveys are located along or east of this major fault in a 10 km (6.2 miles) long, narrow zone. The highest recorded water temperature in the valley appears to be 62.7 C (145 F) at 137.2 meters (450 feet) in a well at Boyes Hot Springs. This is consistent with the geothermal reservoir temperature range of 52-77 C (126-171 F) indicated by geothermometry calculations performed on data from wells in the area. Interpretation of data indicates a low-temperature geothermal fluid upwelling or ''plume'', along the ''east side'' fault with subsequent migration into permeable aquifers predominantly within volcanic strata. It is quite likely other geothermal fluid ''plumes'' in association with faulting are present within the Sonoma Valley area. A 5.8 km2 geothermal zone, that parallels the fault trace, is delineated and is perhaps the most favorable area for further investigation and possible geothermal production.

This book was released on 1976 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Guidelines for the engineering geology assessment of The Geysers Geothermal Resource Area (GRA) are presented. Approximately 50 percent of the geothermal wells and some of the power plants are presently located on landslide areas. Several geothermal wells have failed, causing additional land instability, loss of energy resource, and unnecessary expense. Hazardous geologic conditions in the area are identified, and measures for mitigating those hazardous conditions are recommended. Such measures or other equally adequate measures should be considered for any proposed development activity in The Geysers area.
