Product Sheet TuffPac Nonrotational High-Performance Service Packer
Withstand severe shock, high flow rates, and high pressures and effectively isolate annulus fluids.
The TuffPac nonrotational high-performance service packer is a fullbore, cased hole, retrievable compression-set packer for testing and tubing-conveyed perforating operations. It withstands severe shock, high flow rates, and high pressures when the appropriate slacked-off weight has been applied to the packer. The sealing elements effectively isolate annulus fluids from the perforated interval.
The TuffPac packer replaces conventional turn-to-the-right packers and mechanical-set packers. It consists of a slip lock module, continuous-indexing J slot, slip assembly, and elements assembly. The highstrength material and robust design makes it suitable for severe load conditions normally seen during perforation of deep wells as a result of gun shock.
The packer can be cycled simply by string reciprocation from the safety position to the set position and back to the safety position. This is particularly beneficial in highly deviated wells, where applying rotation down to the rotation-set packers might be difficult. The reciprocation setting also eliminates rotation of subsea umbilicals during the setting process.
