DOE Grant No. DE-FG02-00ER83035

Amount:  $99,800

 

Today's geothermal pressure-temperature measuring tools are short endurance, high value instruments, used sparingly because their loss is a major expense.  In this proposal, LEL Corporation offers to build and test a rugged, affordable downhole sensor capable of returning an uninterrupted data stream at pressures and temperatures of 10,000 psi and 250°C, respectively, thus permitting continuous deep-well logging.  The research and analysis of the TCT transducer will provide a working prototype to be tested under laboratory conditions at the completion of the Phase I effort.  Commercialization during the Phase II effort will expand the optical sensing features to measurements of displacement, force, acceleration and temperature to 500°C.  Design, build and test a sensor capable of reading pressures up to 10,000 psi with 5 percent FS accuracy at a temperature exceeding 250°C.  Though the "test depth" is 3 meters in a laboratory environment, testing will clearly demonstrate the transducer's potential for continuous duty in a geothermal setting.

 

Commercial Applications and Other Benefits as described by the awardee:  The sensor technology can be used to monitor jet engine core pressure, petrochemical processes, hydraulics, heavy construction equipment, high pressure metal cutting, oceanography, nuclear power plants, injection molding, processing industries, machine tools, mining and research organizations requiring similar gains in performance and reduced cost.
