Project Description:
The purpose of this project is to research the feasibility of developing a borehole seismic receiver array for geothermal wells capable of operating in a temperature range of 200o-250oC. A five-level prototype receiver array will be fabricated and tested under field conditions.
Proposed Outcomes:
· Cable design capable of withstanding operational temperatures of 200o–250o C.
· A prototype five-level high-temperature borehole seismic receiver array.
· Feasibility assessment based on prototype performance testing in field setting.
Anticipated Benefits:
· Ability to record P and S wave data that enable the mapping of fracture zones in high-temperature geothermal reservoirs.
· Enable more efficient management of existing geothermal reservoirs.
· Reduce the number of wells needed to develop a geothermal resource.
· Allow economic development of lower temperature and lower permeability geothermal fields.
