Revolution Heat

Contact

Enables precision drilling in high-pressure, high-temperature (HPHT) environments

Applications

  • Extended-reach drilling in HTHP wells
  • Directional drilling and logging while drilling (LWD) in HTHP environments
  • Continuous, real-time measurements of near-bit inclination and gamma ray
  • Formations that require reduced slide intervals

Features

  • On-the-fly downlinking that reduces nonproductive time and enables precise steering control
  • On-board sensors that measure vibrations, whirl, and stick-slip, which enables operators to implement mitigation strategies in real time
  • Use of high-viscosity oils to maintain the integrity of the hydraulics in an HTHP environment
  • High-temperature-rated Kalsi Seals® that provide hydraulic oil integrity at higher temperature*
  • An available motorized option for greater rate of penetration
  • Compatibility with all Weatherford LWD systems

Benefits

  • Reduces complexity in HTHP environments with complete RSS and LWD evaluation capabilities
  • Positions critical LWD measurements close to the bit for more accurate geosteering
  • Improves hole quality, which makes cuttings removal more efficient and enables casing and liner systems to run smoothly to total depth
  • Yields a high build rate in deviated wellbores, yet can be configured to maintain low tortuosity in lateral and tangent applications

Tool Description

The Revolution Heat rotary-steerable system (RSS) enables extended-reach drilling in wells with temperatures exceeding 300°F (149°C). The tool improves hole quality and cuttings removal while increasing drilling rates.

The tool has a short, compact design that reduces the complexity of rotary-steerable drilling technology and places critical LWD measurements close to the bit. It can be combined with a comprehensive range of advanced Weatherford HTHP LWD sensors to deliver a complete drilling and evaluation service in extreme well conditions.

The Revolution Heat RSS is available in multiple sizes for drilling holes ranging in size from 5-3/4 to 26 in. The 4 3/4-, 6 3/4-, and 8 1/4-in. models are available with either standard stroke or reduced stroke (RS).
