RGS Steering (RGS-ST)

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 wellsite:

• 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, North Sea, Middle East and Argentina. 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.
