Eliminates errors in cement-displacement volumes by producing a recognizable indication when the cementing top plug passes through the locator collar Applications
Features and Benefits
The Weatherford plug locator system produces a recognizable indication when a cementing top plug passes through a locator collar at a predetermined distance above the float or landing collar in the casing string. Observed at the surface, the indication enables verification of cement displacement to eliminate cementing errors.
A surface pressure increase between 300 and 900 psi (2.068 and 6.205 MPa)* indicates when the top plug passes through the locator collar. The system achieves accurate displacement by pumping the calculated volume between the locator and landing collars until the top plug bumps against the landing collar.
The system meets the temperature and pressure ratings of Weatherford plugs equipped with polyurethane fins and Duromer™ cores.
