MODEL BKR PREMIUM CEMENT RETAINER MECHANICAL SET

MODEL BKR PREMIUM CEMENT RETAINER MECHANICAL SET

The Model BKR Premium Cement Retainer (MS) is a mechanical set, high pressure retainer constructed of drillable cast-iron that runs on an ACT, Alpha, Bolt, Elder or Baker K-1 type Mechanical Setting Tools. When set, opposing slips are located above and below the rubber packing elements.

 The packing elements are contained by rocker action back-up rings that eliminate extrusion of the elements at high temperatures and pressures. A one way ratchet lock ring retains the setting force applied to the opposing slips and rubber to maintain a pressure tight seal.

One-piece slips keep the retainer securely set in premium grade casings including P-110.The slip wickers are sharp and hardened to the wicker depth only allowing the slip to grip the casing wall while maintaining a soft cast-iron inside for easier drilling. After the BKR cement retainer is set mechanically the squeeze operation can begin. It features a pressure balanced two way valve located in the bottom shoe. The operator controls the two way valve from the surface to hold the final squeeze pressure under the retainer or test tubing or keep hydrostatic pressure off the squeeze. Straight pick up closes the valve and set down weight opens the valve. This retainer is ideal for where squeeze cementing operations are being performed. Optional packing systems of Viton or Aflas are available on special order. Special application tools can be custom designed to fit your specific needs.
