TAM International, Inc., an independent oilfield services company providing inflatable and swellable packers, has introduced a new technology as part of its PosiFrac® product line. The TAM PosiFrac® Toe Sleeve (PTS) assembly is designed for cemented or uncemented completions where a casing pressure test is desired to confirm casing integrity prior to opening the toe sleeve. The PTS is distinguished by allowing for more than one casing pressure test without the need to pressure above the test pressure to open the sleeve.
One or more PTS tools can be installed at the toe of the well, and each PTS will cycle open independently during the final casing pressure bleed-off cycle. This allows multiple entry points to the reservoir, so the first stage can be fractured immediately before plug-and-perf operations begin.
“The PosiFrac Toe Sleeve technology sets a new standard for the industry,” said Ray Frisby, TAM’s Vice President – Western Hemisphere Operations. “Its revolutionary design offers simple operating features for improved reliability when compared with other toe sleeves on the market.”
The PTS is rated up to 18 000 psi (combined hydrostatic plus test pressure) and 350°F (177°C). The design features a large flow area for high-rate fracture treatments and a debris-tolerant actuation system that is compatible with standard cement wiper plugs.
