4-in. System

The Revolution service was the first slimhole

rotary-steerable system (RSS) to use point-the-bit drilling technology for improved borehole quality and bit life. The Revolution system’s short, compact design reduces the complexity of rotary-steerable drilling technology, while placing critical LWD measurements close to the bit.

The Revolution system’s point-the-bit technology

uses a pivot stabilizer to orient the drill bit axis with the axis of the desired well path, optimizing the directional drilling process and maximizing drilling efficiency. Relative rotation between the center shaft, which carries torque to the bit, and a non-rotating outer housing drives a hydraulic pump. This pump generates enough motive force to deflect the drillstring as programmed in the well’s steering plan.

Extended-reach 6- to 6 3/4-in. wellbores

Applications

Point-the-bit design for improved hole quality and bit life.

Simple functionality ensures high reliability.

Deviation rates set from surface for improved directional control.

Build rates of up to 10°/100 ft depending on formation type.
