Overview
Overview
When you need practical, real-time answers on formation changes while drilling, count on the ZoneTrak R™ at bit resistivity service from Baker Hughes. By providing qualitative resistivity measurements at the bit, the ZoneTrak R service helps you increase reservoir exposure while avoiding wellbore stability risks.
The logging-while-drilling service is ideal for all geo-stopping applications in formations containing high-resistivity contrasts, and accurately identifies the top of your reservoir. By increasing reservoir exposure, you can maximize your coring section intervals, and ultimately, increase your reservoir production.
The ZoneTrak R service’s efficient geostopping helps you more accurately select casing and coring points. The service also lets you locate the entrance and exit points to critical formations like salt and overpressured zones. Armed with this information, you can avoid entering trouble zones that increase your risk of well control issues and loss of circulation.
Data provided by the ZoneTrak R service can also be used to update your reservoir models for improved navigation while drilling. You’re assured more optimal placement of the wellbore into the most productive part of the formation.
Optimize the size of the service tool you need for positive zone identification by relying on our GaffneyCline Energy Advisory experts. The RTS team works with you to understand the specifics of your operation—including bottomhole assembly configuration, mud resistivity, formation resistivity contrast to be detected, and the wellbore’s incident angle with the formation. Our experts then build a model of the tool’s response with depth to determine the optimal length of electrode necessary to accurately measure resistivity changes in your formation.
The ZoneTrak R service tool works effectively in any drilling mud and is compatible with both rotary steerable and conventional rotary assemblies. And with maximum pressure and temperature ratings of 30,000 psi and 150°C (302°F), you can confidently collect critical resistivity data while drilling in deepwater and other extreme environments.
