According to required needs, we have engines of:

Faster turns and low torque
Lower turns and high torque

These are repaired according to our Preventive Maintenance Program.

Benefits are at sight, given that just by turning the milling took with the lower part of the engine bearing, the column within the well does not suffer any type of wearing nor torque excess due to the rotation, as we avoid using the rotary table.
Casing string (csg) prolongs its useful life, as it does not suffer rubbing in all its length and the production tubing column does not suffer excess of torque nor wear at its coupling.
