Considerations in the Use of Water Jets to Enlarge Deep Submerged Cavities
While the use of geothermal energy is growing, environmental considerations have raised potential economic barriers to its future progress. In order to facilitate use of reinjection wells, and to lower their cost, it has been proposed that a single well be reamed from 22-1/2 cm to 2 m diameter over an increment of 70 m at a depth of 2000 m. In this manner a single well would be capable of coping with flow rates which currently necessitate a dozen wells being emplaced. The problems encountered in using high pressure water jets for this reaming operation are described. Limiting parameters on the use of high pressure water jets and their operating diameters are identified. The considerable advantages to the use of long chain polymers in such a hostile environment are also delineated.
