RGS Battery Powered (RGS-BT)
A new downhole power module eliminates the need for electric wireline and significantly reduces the cost of high precision wellbore surveying.
Innovation
The battery powered rate gyroscopic surveyor (RGS-BT) is a major advancement in wellbore survey, offering significant costsavings by eliminating electric wireline.
RGS-BT incorporates a new downhole power and data-storage module with a directional sensor array to provide the industry's first battery-powered borehole survey system based on modern aerospace guidance technology.
Systems are configured with downhole data storage for up to 8,190 survey readings, allowing the addition of battery power module and unique operational flexibility.
Applications
- Single/multishot surveys in drillpipe, casing, tubing, open hole.
- Orientation of directional drilling assemblies, whipstocks, packers, perforating guns, logging tools.
- Tandem operation with logging tools.
- Saves significant costs by eliminating the need for electric wireline.
- Saves rigtime by running during the trip out of the hole in drillpipe, compared to a normal gyro run on electric line in casing.
- Virtually no depth limitation with 16 hours of run power and storage for 8,190 survey readings.
- No wait at a connection during the trip out to take survey information.
- Provides rate-gyroscopic survey accuracy in drillpipe prior to running casing, and also surveys upper casing strings during the run in drillpipe.
- The probe also runs on electric wireline for multiple applications at the wellsite.
The battery system is connected to the surface computer to check system functionality. The tool is then rigged up and run in the hole on slick or braided line. Survey data is collected at each point when the tool is stopped downhole and depth is entered versus time. Upon retrieval of the tool at surface, survey data downloads immediately to the laptop computer.
