Abstract
An improved single trip perforating and gravel pack system is provided which includes a tubing conveyed perforating assembly, a gravel pack completion assembly, and a retrievable service assembly. The retrievable service assembly includes a hydraulic setting tool and a crossover tool assembly. The hydraulic setting tool is less sensitive to hydraulic pressures generated by the detonation of the perforating guns. The hydraulic setting tool includes an annulus release mechanism, a preset lock assembly and a rotational lock assembly, all of which are mechanically actuated. The retrievable service assembly also includes a concentric check valve which improves well control and allows for reversing out excess slurry in the service assembly following completion of a gravel packing or frac packing operation.
