Open hole packer for high pressure service in a five hundred degree fahrenheit precambrian wellbore
Massive hydraulic fracturing (MHF) from a lower wellbore (EE-2) created a large man-made reservoir which did not intersect the upper well (EE-3). To create a heat extraction flow loop, the upper well was sidetracked and redrilled (EE-3A) down into a microseismic cloud around EE-2 mapped during the MHF. The potential to intersect numerous fracture zones in the redrilled bore was apparent from seismicity. To economically and effectively isolate and test these microseismic zones required that a functional open hole packer be developed. The packer would be exposed to soak temperatures as high as 500/sup 0/F (260/sup 0/C) with cool down to 100/sup 0/F (40/sup 0/C) at differential pressures exceeding 5000 psi (35 Mpa). A functional packer has been designed, manufactured, and successfully used for the creation of a hot dry rock (HDR) reservoir. 5 figs., 1 tab.
