Weatherford’s Eliminator stage tools allow cementing of casing string in either two or three stages. These tools set the standard for reliability, cost effectiveness, and ease of use with outstanding built-in features and quality. They are the tools of choice when drilling requirements call for proven technology and low risk. Model 751E is used for two-stage cementing. Model 752E is used for three-stage cementing. Models 751PD and 752PD, respectively, are the PDC-drillable versions of Models 751E and 752E.

Applications

• Reduce total pumping pressure in long casing strings
• Reduce total hydrostatic pressure on a weak zone to prevent lost circulation
• Enable selective cementing of formations

Features, Advantages and Benefits

• The compact, simple design minimizes the number of moving parts and makes the tools easier to handle
• The tool’s clear opening and closing indications at the surface accommodate the hydraulic conditions of the well for safer, more efficient operations
• Locking and anti-rotation devices accelerate drillout to save rig time while the tool’s greater wall thickness provides superior strength
• The smaller-OD models create a larger fluid bypass area during circulation and displacement, minimizing the effect of pressure on sensitive formations
• The internal sleeves increase reliability and prevent premature opening from formation restrictions or applied pressures
• The unitary sleeve opens and closes the tool, which eliminates pressure traps and increases reliability
