The Potential Advantages of a Water Jet Reaming Device
One of the advantages sought for new technology, if it is to become a useful device, is that it should increase productivity while keeping the operation economical. In this regard, water jet reaming of geothermal wells for both exraction and re-injection appears to show promise. It is shown, using conventional formulae that reaming geothermal wells from 12 cm to 1 m radius will increase fluid flow to the point that 25% less wells could be required to establish a geothermal field. With this objective, experiments are described to verify that water jets can effectively cut rock at required level, that is at a depth of 2000 m in a fluid filled borehole. A conceptual mechanism to achieve this reaming is developed and, in simple form, the concept is demonstrated in a surface test. (A)
