Casing Drift
Casing Drift is designed for drifting the production string before running the equipment and checking the internal diameter of the string, simulating the equipment in length and outer diameter. As templating elements, aluminum bushings are used, which have longitudinal grooves for the possibility of fluid circulation during the run. Unlike steel, the use of aluminum bushings provides easier release of the drift when wedging in the casing, and is also more informative in the presence of damage or changes in the internal diameter of the casing.
