Bradenhead squeeze Definition


Bradenhead squeeze:

A process used to repair a hole in the casing by pumping cement down tubing or drill pipe.

First, the casinghead, or bradenhead, is closed to prevent fluids from moving up the casing.

Then the rig’s pumps are started.

Pump pressure moves the cement out of the tubing or pipe and, since the top of the casing is closed, the cement goes into the hole in the casing.

The tubing or pipe is pulled from the well and the cement allowed to harden.

The hardened cement seals the hole in the casing.

Although the term “bradenhead squeezing” is still used, the term “bradenhead” is obsolete.
