To address the demand for improved zonal i … To address the demand for improved zonal isolation devices, CTD is proposing to develop high-temperature high-pressure packers based on its experience developing remotely and autonomous deployable structures for space and our high temperature composite technology developed for downhole applications. These devices offer several attractive features for EGS applications, including autonomous setting once the tool has been positioned downhole and the ability to retrieve the zonal isolation device.ty to retrieve the zonal isolation device.

For Enhanced Geothermal Systems (EGS), hig … For Enhanced Geothermal Systems (EGS), high-temperature high-pressure zonal isolation tools capable of withstanding the downhole environment are needed. In these wells the packers must withstand differential pressures of 5,000 psi at more than 300°C, as well as pressures up to 20,000 psi at 200°C to 250°C. Furthermore, when deployed these packers and zonal isolation tools must form a reliable seal that eliminates fluid loss and mitigates short circuiting of flow from injectors to producers. At this time, general purpose open-hole packers do not exist for use in geothermal environments, with the primary technical limitation being the poor stability of existing elastomeric seals at high temperatures.
Key elements of the work plan include designing materials and mechanisms based on advanced shape-memory polymer materials, constructing prototype packers, and demonstrating their performance relative the needs of the geothermal industry.tive the needs of the geothermal industry.
