Proppant-flowback control in high-temperature wells
Proppant flowback following fracturing treatments can be controlled by use of resin-coated proppant, inorganic fibers, or polymer strips. Each of these technologies has limitations. Resin-coated proppants cannot be used above 374 F and require an activator below 158 F. Thermoplastic strips cannot be used at temperatures above their melting point. Glass fibers have been used successfully for proppant-flowback control, but they cannot be used at reservoir temperatures below 302 F, they provide only short-term control in carbonate reservoirs, and they cannot be used in an environment where they would be exposed to HF. A new high-performance fiber for proppant-flow-back control has been developed to overcome these limitations. In laboratory testing, these fibers were resistant to steam, diesel, xylene, HCl, and mud acid at temperatures up to 482 F for periods up to 7 months. Field testing in deep, hot, carbonate reservoirs confirmed the performance of the new fiber. Case histories of gas wells are given.
