Abstract

The Sand Crown Frac Pack Sleeve is a three-stage sliding sleeve system. The starting position is closed, the second position is open to frac, and the third position is open to produce through a sand screen. It is designed for multi-zone single trip stimulation in formations requiring both fracture stimulation and sand production protection. A completion tubular is placed in position adjacent the zone or zones to be fractured and produced. It features preferably sliding sleeve valves that can assume at least two configurations: wide open and open with a screen material juxtaposed in the flow passage. In a preferred embodiment the valve assembly has three positions, adding a fully closed position to the other two mentioned. After run in, the valves can be put in the wide open position in any order desired to fracture. After fracturing, the valves can be closed or selectively be put in filtration position for production from the fractured zones in any desired order. An internal side pocket protects the internal sleeve from contacting cement during cementing operations. The internal sleeve is then shifted out of the side pocket to expose the fracturing port for fracturing operations, and the sand screen port for hydrocarbon production
