PQX Circulating Sleeve

The PetroQuip PQX Circulating Sleeve is a down hole flow control device installed in the production string to provide communication between the tubing and casing annulus. There are two versions: the PQXO and the PQXA.

The PQXO is opened by shifting the inner sleeve down and closed by shifting the inner sleeve up using standard wireline methods. The PQXA is opened by shifting the inner sleeve up and closed by shifting it down. The PQXA and PQXO circulating sleeves have a nipple profile on the upper sub for installation of flow control locks.

Benefits:

• Multiple sleeves may be run in tandem for multiple zonal isolation and production

• Integral flow control nipple for well control

• Simple positive control of tubing and annulus communication

• Versatile design adaptable to many completion configurations

• Economical way to achieve zonal control
