The City of Susanville is located in northeastern California in Lasen County. It overlies the Susanville Geothermal Anomaly, a low to moderate temperature (180F +/-) resource that is located approximately 100 to 500 feet below land surface. A total of three direct use heating systems operate within the city. These are the City of Susanville district space heating system, the Church of Jesus Christ of Latter Day Saints (LDS Church), and Tsuji Nurseries. The City system is by far the largest, providing heat to 77 users and facilities, with the potential to provide heat to an additional 75 users, including a proposed industrial park. Current production is approximately 500 gallons per minute from two production wells, the Naef Well and Susan-1, with a capacity approaching 900 gpm. The other two systems are used to heat church facilities and a commercial greenhouse operation, respectively.
Two geothermal test wells were drilled and completed in Raft River Valley, Southern Idaho by the Idaho National Engineering Laboratory between January and August, 1975. Subsequently, hydraulic tests were conducted on these welIs to make preliminary estima
We report the results of an eight-year monitoring programme at Ngawha and examine the data to assess the nature of the reservoir fluids and whether any changes have occurred. The main production reservoir contains liquid at 230?C, 1250 mg/kg chloride, and
The Australian Geothermal Industry has made some exciting advances in the last year. Developments have been made in terms of company Engineered Geothermal System (EGS) and Hot Sedimentary Aquifer (HSA) projects, research projects and both state and nation
The twelve abstract categories contained in this set of publications were developed by the staff of the Geothermal Resources Council and twelve volunteer Oversight Committee Members who are experts in their fields. The project management and editing was performed by Claudia Stone and the names of the twelve committee members appear on the front of each Abstract Set.
The purpose of this study was to determine the feasibility of geothermal resource utilization at the Puna Sugar Company cane sugar processing plant, located in Keaau, Hawaii. A proposed well site area was selected based on data from surface exploratory surveys. The liquid dominated well flow enters a binary thermal arrangement, which results in an acceptable quality steam for process use. Hydrogen sulfide in the well gases is incinerated, leaving sulfur dioxide in the waste gases. The sulfur dioxide in turn is recovered and used in the cane juice processing at the sugar factory.
The clean geothermal steam from the binary system can be used directly for process requirements. It replaces steam generated by the firing of the waste fibrous product from cane sugar processing. The waste product, called bagasse, has a number of alternative uses, but an evaluation clearly indicated it should continue to be employed for steam generation. This steam, no longer required for process demands, can be directed to increased electric power generation. Revenues gained by the sale of this power to the utility, in addition to other savings developed through the utilization of geothermal energy, can offset the costs associated with hydrothermal utilization.
The recommended system is entirely feasible from a technical viewpoint. It is only marginally profitable based on private financing. However, there is some basis to anticipate partial government participation in the project. This may provide the impetus to carry the program through the implementation
phase and into commercial operation.
We develop a model for the spreading of reacting liquid injected into a permeable rock. We examine reactions which lead to either precipitation and a decrease in permeability or dissolution and an increase in permeability. We focus on the case in which th
