A Middle East operator selected a Titanium XV multi-stage completion system with high pressure/high temperature (HPHT) PrimeSET Liner Hanger to conduct an acid fracturing treatment using open hydraulically set mechanical RockSEAL packers and re-closeable FracPORT sleeves.
The multicycle FracPORT sleeves were strategically chosen by the operator to perform an efficient acid fracturing treatment in 6 stages. The FracPORT sleeve is run in a pinned configuration with a ball seat and is sheared when desired by dropping the corresponding ball size, providing positive pressure indication that the specified port has opened before fracturing. Later, the sleeves can be opened, closed, and reopened, enabling operators to manage production using the Coiled Tubing (CT) Drillable Closeable Hydraulic (DCH) shifting tool for selective stimulation and flowback from distinct or combined producing zones. Studies have shown that refracturing can be an effective practice in tight reservoirs over long periods of time. Additionally, these sleeves facilitate the re-stimulation of the wellbore or closure of water-producing zones during future interventions.
