Washover Shoes

Free stuck pipe in the wellbore

Washing over is an effective method of freeing stuck pipe in the wellbore by cutting away and circulating out obstructions that hinder pipe movement. Available in various configurations and sizes from 2 1/4 to 24 in, washover shoes and associated equipment are built with integral joints for job design flexibility. They are also constructed with rugged N-80 grade (or greater) casing or tubing, with even higher-specification materials available for more specialized applications.
