M-Power Shoe

The innovative third generation GJS hydraulic system GEN3.X was created by Powell to increase the commercial speed of well construction by running casing strings without preliminary preparation and cleaning of the wellbore.

About

Powered drilling solution for complicated wells with reinforced worked section.

The main engineering challenge was a significant increase in the shoe rotation speed of more than 3500 rpm to reduce the working displacement while maintaining power and reducing the time for working out complications during running the casing string, as well as the resistance of the power section to the abrasive effect of the drilling fluid.

Instant start of rotation when circulating flow makes it possible to start development at low displacement without the risk of lost circulation or hydraulic fracturing at an increased flow rate
Significant increase in power to reduce turnaround time
Increase in the shoe life due to the special coating of the elements of the power section.
