MEMS memory rate gyro system  The isGyro is a user-friendly borehole survey tool that offers you high accuracy in oil & gas applications. Download and processing times are fast and the tool can survey for up to 16 hours on a single battery charge. No special pre- or post-survey procedures are necessary to get into the hole. The simple set-up saves valuable site-time and potential sources of human error are significantly reduced. The modular design of the tool minimizes repair times and cost.

All new versions of Inertial Sensing gyros are capable of running in both standard multi-shot mode as well as the new fast continuous survey mode. Survey data from a continuous survey can easily be reprocessed to any required station interval.

High rate capability  Each system is equipped with an extra roll axis gyro covering rates up to 1,000 deg/s. These high rate gyros accurately track rapid angular changes caused by wireline torque release or angular shock from the rotary unit when tripping rods.

High-speed data transfer and processing The isGyro delivers accurate results at high speed: 1 hour's worth of survey data is processed in seconds while data download requires just 4 minutes. This is achieved by our unique combination of advanced sensors, microprocessor systems, efficient data collection and processing techniques.

Low power consumption The isGyro™ has a power consumption of only 0.2 W. The system can also be used in single mode to preserve power. An additional delayed start mode allows the system to be initialized in 5 mW sleep mode to wake up for surveying after a pre-set time.
