Gyrodata’s rate-gyroscopic steering system provides real-time surface readout of orientation data while drilling-offering considerable time savings, exceptional reliability, and more staying power than any other system available today.

Applications

The steering system replaces magnetics for any orientation or guidance operation:

  • Drilling motors/assemblies
  • Whipstocks/packers
  • Coiled tubing guidance

Operation

The system performs multiple survey functions at the well site:

  • Steering is conducted with the probe seated in the muleshoe sub, providing realtime toolface data at surface on the driller’s console.
  • Multishot surveys can be taken while traversing to seat for steering operations, while pulling out, or during other operations, such as whipstock orientation runs.
  • Wet-Connect systems and top-entry subs eliminate the side-door sub.

Advantages

  • Staying in the hole versus pulling out after each orientation run saves considerable rigtime.
  • Steering provides realtime drilling torque information.
  • Rate-gyro accuracy and speed enhance operational efficiency and save time.

Special Features

  • All angle/direction operation provides surveying in horizontal drilling.
  • Heat Resistance: RGS-ST offers the highest heat capacity versus time of any small diameter gyro system. While other tools use costly rigtime pulling out to cool off, RGS-ST’s unique temperature modeling gives it the power to stay on bottom. A record 31 hours was logged in the Austin Chalk at 146°C with the 1.75-inch steering gyro probe.
  • Rate-gyro accuracy and speed enhance operational efficiency and save time.

Experience

RGS-ST has been proven throughout many regions, including the U.S. Gulf Coast, Rocky Mountains, Canada, the North Sea, Middle East, and Latin America. Case histories include:

  • Wyoming re-entry: 2 7/8″ drillpipe, 3½” motor orientation. 1.75″ OD steering gyro run – 139 hours in hole at 125 g.p.m.
  • Austin Chalk re-entry: 12,000 feet, drillpipe, motor. 1.75″ OD steering gyro run for 12 hours at 250 g.p.m.
  • Austin Chalk re-entry: 8,000 feet, drillpipe, motor. 1.75″ OD steering gyro run for 8 hours at 250 g.p.m.
  • Canada re-entries, 4: whipstock orientation; 1.75″ OD steering gyro run for coiled tubing guidance.
  • Argentina re-entries, 3: whipstock orientation; 1.75″ OD steering gyro run for coiled tubing guidance.
  • Middle East re-entry: 11,000 feet, whipstock orientation; drillpipe, motor; 1.75″ OD steering gyro run for 41 hours at 138°C building to 30° inclination.
