BD Cement Retainer

BD Cement Retainer The Ball Drop Cement Retainer, is a proven design, that can be used during surface casing gas migration cement squeezes. A ball drop selective cementing application directs cement flow through the tight formation, ensuring 360° cementing coverage of the annulus. The internal valve is a pressure balanced valve when closed, and acts as a standard Cement Retainer. It is opened or closed with pipe manipulation, to allow, or isolate flow in high differential pressure scenarios.

Key features

• Fully pressure testable prior to remedial operations
• Valve automatically opens and closes with removal of the stinger
• Easily drilled due to rotationally locked components
• Can be converted between mechanical or wireline set
• Able to reliably pass through a ø15.9mm or ø22.2mm ball Bridge Plugs & Retainers Available Sizes

High Flow Cement Retainer

High Flow Cement Retainer

Key features

• Large flow area for fluid dumping as in a disposal, or large cement squeeze
• The bypass ports are aligned for maximum fluid movement with minimum
• When the valve is open, the seals are protected from fluid erosion.
• The valve sleeve is pressure balanced to prevent sudden opening from creep. features to prevent premature setting of the retainer or bridge plug or damage to the tool. It is suggested that the tool be run at a moderate speed while avoiding sudden stops. Note: While running in, care must be taken to prevent right-hand rotation from being transmitted to the setting tool. Under no circumstance must there be allowed more than four turns of the tubing to the right while running in. As a precaution, after every 10 to 15 stands, at least one or more left hand turns should be placed in the work string to assure the control nut is “bumped up”. When the desired setting depth has been reached, the tools should be picked up two (2) feet above the desired setting point. This movement is necessary to provide the required tool stroke to release the upper slips and allow the Control Nut to move freely. Rotate the work string to the right sufficiently to transmit 10 turns to the tool. This right-hand rotation will thread the Control Nut off its matching thread on the Mechanical Setting Tool mandrel and release the Control Sleeve from the running in position. Lower the tools back down to the desired setting depth. The Drag Blocks will support the Control Sleeve and Setting Sleeve. The downward motion will push the upper slips from under the Setting Sleeve. attached to the inside of each slip segment. When the upper slips are released, the Retaining Sleeve is pulled from over the Dog allowing it to move out and release the Control Latch from the Stinger Sub Body.

Set down weight equal to the calculated weight required to prevent the slide valve from closing during pumping operations.

In this event the work string should be alternately picked up and slacked off. This movement will assist the Dog to move outward on the inclined edges of the locking groove in the Stinger Sub Body, thus freeing the Sub Body for the required two (2) inches of vertical The Mechanical Setting tool is released from the Cement Retainer by pulling 500-1000 lbs. tension at the tool and then rotating the work string 10 turns to the right at the tool. This will shear the rotational lock screw and unscrew the Control Latch from After Releasing from a Cement Retainer The Mechanical Setting Tool can be reattached to the Cement Retainer by setting down 3,000 to 5,000 lbs. of work string weight and snapped out again by pulling 8,000 to 10,000 lbs. tension at the Cement Retainer. The Stinger Seal will remain in the Cement Retainer until the snap-out retaining force is exceeded. Each time the Mechanical Setting Tool is snapped in and snapped out, the snap-in and snap-out value is reduced until they stabilize at about 2,500 pounds snap-in and 5,000 pounds snap-out.

Latch Style Cement Retainer

The Latch Style Cement Retainer Stringer is used to operate the valve system in the wireline set Cement Retainer. The snap latch is run on the bottom of the tubing and automatically locates in the retainer bore. The snap-latch seal unit seals in the cement retainer bore and the collet system engages the latch thread at the top of the retainer bore. The collet on the snap latch requires 5,000 to 10,000 lbs. (2,200 to 4,500 daN) force to snap out of the retainer bore. The exact amount of force will depend on the size of the retainer and the amount of time the collet is engaged and disengaged. The snap latch allows for sufficient movement to open and close the valve while maintaining a seal in the cement retainer bore. The tubing is simply picked up to close the valve and set down to open the valve. If it is not possible to remove the snap latch from the bore with a straight pull, then the collet maybe disengaged with right-hand rotation. Bridge Plugs & Retainers Casing O.D. Conn ection

Mechanical Cement Retainer Tool

The Mechanical Cement Retainer Setting Tool is used to run, set, and operate a cement retainer (with mechanical slips) using tubing or drill pipe. Setting Procedure The retainer and Mechanical Cement Retainer Setting Tool are run to depth using tubing or drill pipe. At depth, the top slips of the retainer are set with right-hand rotation. Setting is then com- pleted with tubing tension. At this point the tubing may be pressure tested. Right-hand rotation is used to disengage the setting tool from the retainer. Once disengaged, the Mechanical Cement Retainer Setting Tool operates as a Snap Latch Seal Assembly to operate the valve system in the retainer. Bridge Plugs & Retainers Casing O.D.
