Features/Description

• Sets securely in P-110 casing
• Ratchet lock ring secures dynamic setting force
• Model 'A' features three-piece packing element and rocker-action metal backup rings which combine for superior seal. Rated to 10,000 psi at 300 Deg F
• Model 'E' one piece packing element provides economical performance at 7,500 psi and 200 Deg F
• Case-hardened, one piece slips virtually eliminate premature setting, yet are easily drilled out
• Keyed lower cone reduces drill out time
• Pressure-balanced sleeve valve is opened and closed from the surface for better control
• Both models easily converted to SV bridge plugs
• Both models easily converted for mechanical or wireline setting

Many of the outstanding features of our wireline plugs and packers have been incorporated into the Models 'A' and 'E' Sleeve Valve Cement Retainers. Both are rugged, compact units engineered for fast running downhole on either tubing or electric wireline. Both models feature a positive, pressure-balanced sleeve valve which is opened or closed simply by lowering or raising the tubing. Positively-secured packing elements and one piece slips combine to resist premature setting due to well debris or rough handling and assures protection from the hazards of high-speed running in the well. The Model 'A's three-piece, multi-hardness rubber packing elements provide a highly dependable pack-off system. The metal backup rings prevent extrusion of the rubber at high pressures and temperatures. Because of their design, the metal-to-metal contact developed by these backup rings is made more secure by pressure increases. An internal ratchet lock ring retains the dynamic force induced in the retainers during the setting operation. This simple mechanism assures continued compression of the packing elements regardless of pressure differentials. Case-hardened, one piece slips, designed to bite into the hardest casing, are located at each end of retainer - final assurance of retainer pack-off security. When the need arises, these slips are easily drilled out. The Model 'E' Cement Retainer differs only in the lower cost, lower rated pack-off system. Slightly faster drill out is an added benefit of the Model 'E'.

These Sleeve-Valve Cement Retainers provide a new horizon in dependability, with the economy of all of our tools.

Operating Instructions

The sleeve-valve retainers can be set with either MAP, Gearhart, or Baker wireline pressure setting tools. The setting adapters-contain MAP (and Gearhart) thread connections thus Baker adapter kits are required if a Baker tool is used. The kit converts the lower end of the Baker tool to MAP connections. Kit part numbers are listed in the retainer specification outline.

An adapter rod attached to the setting tool and run through the retainer seal bore attaches to a mild steel release stud located in the shoe at the lower end of the retainer. A setting sleeve attached to the setting tool pushes against the top slip of the retainer. During setting, the sleeve holds the retainer outside components and the rod pulls the retainer central mandrel up; this action sets the slips and packs off the sealing element. The retainer, thus, is set by compression (instead of tension on vital components). At a predetermined tension the release stud parts and allows the setting tool and adapters to be removed from the well.

To rig the retainer for running, first screw the adapter rod to the setting tool and make wrench tight. Tighten the lock nut on the adapter rod against the setting tool bottom piston. Next, attach the setting sleeve to the setting tool and screw it completely back.

Slide the retainer (and top slip) over the adapter rod until the rod bumps the top of the release stud in the retainer. Thread the rod to the stud by rotating the retainer clockwise (wrench on the valve shoe of the retainer). Occasionally, due to rough handling, the collet valve will shift downward thus not allowing the adapter rod to reach the release stud. Should this happen, first remove the set screw in the valve shoe then unscrew and remove the valve shoe. Push the collet valve fully upward inside the retainer body then re-attach the valve shoe and setscrew.

The following is a general guide for the most successful drill out technique

Spudding the work string and variations in rotary speed and set down weight should be used to aid in breaking up large metal parts and preventing bit "tracking".

One or more junk baskets should be used above the bit when normal circulation is employed.

The retainer is run to setting depth in the same manner as a conventional drillable packer or bridge plug. The packer components are shear pinned as a safety measure against premature setting caused by well conditions. Line speed should not exceed 200 feet per minute while running. During setting there may be at least two "kicks" shown on the weight indicator. One kick will indicate shear pins shearing and the last kick will indicate the release stud parting. After setting the retainer, pick up the setting tool a few feet then set back down and tag the retainer to assure the retainer is in place.
