Overview

The dependable ERCD improves casing installation, ensuring the completion of wells to target depth. Situated directly above the casing shoe, the ERCD creates an axial vibration and uses surplus stacked weight to reduce the excess drag of the casing string and allow it to slide effectively. As an added benefit, the liquefaction of cement, assisted by the vibration of the “ERCD”, ensures drilling fluid is displaced effectively, resulting in a more reliable cement job and reduced fluid channeling.
