Geo-Pilot® GXT Rotary Steerable System

Setting Direction with the Pilot™ Fleet

Geo-Pilot GXT Rotary Steerable System Tool

Part of Sperry Drilling services' Pilot™ fleet of automated drilling systems, the Geo-Pilot® GXT rotary steerable system establishes a new benchmark for performance drilling.

Delivering increased horsepower and revolutions per minute directly to the bit, the Geo-Pilot GXT system overcomes challenging formations while reducing the occurrence of stick-slip. The system gives you the ability to achieve higher penetration rates while minimizing casing wear by decoupling the bit speed from the drill string speed.

The Geo-Pilot GXT system delivers this new level of drilling performance by integrating a GeoForce® motor power section between the rotary steerable system and the LWD system. This next-generation positive displacement motor technology produces more than twice the horsepower of conventional power sections.

Applications

  • Performance drilling
  • Extreme extended reach drilling
  • Harsh environment drilling
  • High cost drilling
  • Bit speed-sensitive formations

Benefits

  • More energy is directly applied to the bit improving cutting efficiency and rate of penetration while also overcoming stick-slip
  • Decoupling of the bit from the drill string reduces transmission of vibrations to LWD and other BHA components, improving life
  • Drill string rotary speed can be reduced to minimize casing wear while bit speed is optimized for best drilling performance

The Geo-Pilot GXT rotary steerable system is fully integrated with all Sperry Drilling LWD sensors and the InSite® rig information management system to provide a complete real-time drilling and formation evaluation package.

Summary Summary Angola: 24-inch Geo-Pilot® XL System Drills Vertical and Build Sections in a Single Run Sign in required
Angola deepwater exploration well: Vertical and build sections of the 24-inch by 42-inch hole (405 meters/1,329 feet) were drilled in a single run.
Summary Summary North Sea: Drilling Performance Workflow Solution Helps Save 25 Days in HP/HT North Sea Well Sign in required
Halliburton provided a Drilling Performance workflow solution, integrating the expertise and advanced technical capabilities of Baroid, Drill Bits and Services and Sperry Drilling services to meet the specific challenges of the well.
Summary Summary The Netherlands: Geo-Pilot® GXT Rotary Steerable System Cuts Planned Drilling Time in Half Sign in required
The operator drilling a well in the Netherlands wanted all hole sections drilled shoe-to-shoe safely and efficiently.
Summary Summary North Sea: Geo-Pilot® GXT Rotary Steerable System Helps Double ROP Sign in required
In a gas condensate development well in the UK central North Sea, an operator needed to drill through the hard Upper Cretaceous Chalk Group of formations with the highest rate of penetration (ROP) possible while performing constant directional work.
Summary Summary Oklahoma, USA: Geo-Pilot® GXT System and DrillDOC® Tool Help Improve Drilling Performance in Shale Reservoir Sign in required
An operator in Oklahoma recently saved three days of drilling time by using a drilling solution provided by Sperry Drilling comprised of a Geo-Pilot® GXT rotary steerable system and a DrillDOC® drilling optimization tool.
Summary Summary Australia: Geo-Pilot® GXT System Improves ROP by 30% and Reduces Drilling Time in Hard Limestone Formation Sign in required
The operator of an Australian oil field required a solution to reduce destructive vibration and improve rates of penetration (ROP) while drilling a troublesome hard limestone and chert formation.
Summary Summary Gulf of Mexico: Geo-Pilot® GXT 9600 Rotary Steerable System + Quad-Combo Solution Delivers Section Benchmark Performance in Ultra-Deepwater Exploration Well, Saving Operator Approximately $2,200,000 Sign in required
This exploratory well in ultra-deepwater near the marine border between the U.S. and Mexican Gulf of Mexico, presented challenging water depths of over 8,000 feet (2,500 meters), a seabed temperature of approximately 35 degrees Fahrenheit (3.5 degrees Celsius), and restrained logistics due to severe weather. The “J” profile well was planned to evaluate hydrocarbon potential in a reservoir located under a multi-fault block near a salt dome. Downhole stress could impact build capability during drilling and make it difficult to achieve the planned well trajectory, which had a maximum inclination of 28.5 degrees and azimuth of 165 degrees.
Summary Summary Middle East: Geosteering Solution Delivers Record Performance, Cuts Seven Days from Lateral Well, Saving Customer an Estimated $400,000 Sign in required
In this mature field, the customer planned to drill a lateral well located inside a restricted area. The plan was to drill the build section in 8-½-inch to land the well in the limestone “A” reservoir. Then, in the 6-1/8-inch section, to steer the lateral section inside both the “A” and “B” reservoirs. Specifically, the customer required geosteering to drill the “A” reservoir for 1,500 feet, then drop angle and enter the “B” reservoir, building to horizontal then holding angle to drill the remaining 900 feet inside the “B” reservoir.
