Bullhead Squeeze

The process by which hydraulic pressure is applied to a workstring or tubing to force fluids, such as cement, outside the wellbore. Annular flow (returns) is prevented by a packer set in the casing above the perforated and/or open hole interval. The packer shields the inner casing wall from exposure to the pumping pressures.
