Pinn Port Communication Sleeve



A high performance purpose built, ball activated ported sleeve, the Pinn Port Communication Sleeve was designed as an annular communication device, and is part of the PINN POINT MultiStage Stimulation System. On the fly ball activation is able to open sleeves, independently accessing a pre-selected section of formation for treatment. Up to 19 Pinn Port Communication Sleeves are able to be stacked in a single installation. The composite ball design is unique in that it assures extreme high strength for large volume, high pressure fracture treatments. The geometry of the seat and material structure also guarantee simple, fast, full mono bore I.D. drill out post treatment if required. In applications for which it may be desireable to close a particular sleeve, the Pinn Port is available in a selective open/ close version. This may be used at any time after drill out of the ball seat. Field proven design of the activation balls provide impact resistance and compressive load capability, as well as low density ease of retrieval or drill out.

The extremely compact Pinn Port design of 0.63 m (25”) in length and 139.7 mm (5.50”) O.D. provides ease of handling and rig floor make up, trouble free deployment into difficult well profiles, and liner flexibility. The Pinn Port communication sleeve is rated at 69,000 kPa (10,000 psi) differential pressure. Available in a wide variety of materials and thread connections.
