CMR Mechanical Set Cement Retainer

CMR Mechanical Set Cement Retainer

Model CMR Mechanical Set Cement Retainer is used for secondary cementing, acidizing or fracturing operations. It is compact, small OD and designed for easy drill-out. A ratchet lock ring stores the setting force in the plug. The one-piece packing element and metal backup rings combine for a superior seal. The case hardened, one-piece slips virtually eliminate premature setting, yet can be easily drilled out.

The pressure balanced sleeve valve is opened and closed by tubing manipulation from the surface for better control. It allows tubing pressure test before squeezing. The valve automatically closes when the stinger is picked up, thus locks in the squeeze pressure. The valve protects sensitive zones in low fluid wells.

Model CMR Mechanical Set Cement Retainer is set with tubing or drill pipe run Model CSR Mechanical Setting Tool.

Setting and squeezing can be performed in one trip without retrieving the setting tool.
