Weatherford Revolution - Model Core RSS -Rotarv-Steerable System

The RSS uses a pivot stabilizer to orient the drill-bit axis with the axis of the planned well path, which optimizes the directional-drilling process and maximizes drilling efficiency. The relative rotation between the center shaft, which carries torque to the bit, and a nonrotating outer housing drive a hydraulic pump. This pump generates the motive force to deflect the drillstring as programmed in the well plan.

The RSS is available in multiple sizes ranging from 5-3/4 to 18-1/4 in. The 4 3/4-, 6 3/4-, and 8 1/4-in. models are available with either standard stroke or reduced stroke (RS).

• Drilling extended-reach, underbalanced, and tangent wells
• Drilling from vertical and building to horizontal
• Drilling informations that require reduced slide intervals

• The point-the bit design improves hole quality, which increases cuttings removal speed and enables smooth casing and liner running.
• On-the-fly downlinking reduces nonproductive time and enables precise steering control.
• On-board sensors measure vibrations, whirl, and stick-slip, which enables real-time mitigation strategies.
• Near-bit sensors provide critical logging-while-drilling (LWD) measurements for more accurate geosteering.
• Near-bit stabilizers improve hole quality and bottomhole assembly (BHA) stability.
• A motorized option is available to further improve rate of penetration.
• The rotary-steerable system (RSS) is compatible with all Weatherford LWD systems.
• The tool drills with a high build rate in deviated wellbores, yet it can be configured to maintain low tortuosity in lateral and tangent applications.
