GyroStar™ Gyro-While-Drilling Service

Place Wells More Accurately With Faster Surveys and Precise Measurements

For drilling complex offshore developments or multi-well pads, more speed and precision is critical. The GyroStar™ gyro-while-drilling service from Halliburton Sperry Drilling delivers groundbreaking technology that significantly reduces ellipse of uncertainty, while being two times faster to perform surveys. This improved performance helps you avoid lease lines and mitigate frac hits while enhancing your ability to hit target zones. Powered by SPEAR™ solid-state technology, the sensor package is not affected by shock and vibration under normal drilling conditions, or by magnetic interference.

With the GyroStar service, you will be able to:

Reduce Well Time

  • Eliminates the need to use wireline gyros to steer drilling assemblies
  • Provides full surveys on demand and during connections, with no additional wait time

Drill to Produce

  • Ensures precise wellbore guidance for collision avoidance and trajectory placement
  • By eliminating the need for nonmagnetic spacing collars, the gyro sensor can be run closer to the bit in the MWD string
  • Power/communications feedthrough is capable of versatile positioning in the bottomhole assembly (BHA)
  • Memory multi-shot capability as the BHA is tripped out of hole
  • No mass unbalance or calibration shift
  • No east/west cautionary zones

Let us help you deliver wells faster, and maximize the value of your asset.
