1. n. [Well Workover and Intervention]

A squeeze-cementing technique involving the application of treatment pressure that is higher than the fracture pressure of the formation. This procedure may be necessary to force the slurry into microcracks or annuli that surround the wellbore. The characteristics of a fracture are dependent on the fluid flow rate when the fracture is initiated; consequently, high-pressure squeeze operations must be conducted with a high degree of control to place the slurry in the desired location.
