Sperry Drilling services’ DDSr™ Drillstring Dynamics Sensor measures both downhole shocks and the type and magnitude of vibration affecting the bit and drilling assembly. These measurements provide a full understanding of the exact dynamic conditions at any point in the drilling process.
Helps increase drilling efficiency through the optimum use of drilling parameters, maximizing energy transmission to the bit
Helps extend bit life by reducing vibration damage and premature failure
Helps improve performance by reducing the number of trips for failure
Helps to reduce BHA, tool and tubular failure
Helps to reduce fatigue failure resulting in washouts or fishing
This sensor also exists in SOLAR® version. Please check the sensor data sheet for exact specifications.
In the Nubi Field, offshore Indonesia, a gas development well in 226 feet (69 meters) of water required the critical 12-¼-inch section to penetrate a limestone formation with hard cemented stringers. Typically, in this section, various modes of vibration and problems with sensor pulse detection would damage drilling equipment and hinder formation evaluation data acquisition, slowing progress
and raising costs with excessive tripping.
An operator had a plan to drill a 5,734-ft (1,748-m) ultra-deepwater well in 149 days that was characterized as having high vibration issues in a salt formation and a long history of competitor failures.
Sperry leads the industry with the widest array of MWD/LWD technologies achieved through our focus on formation evaluation - acquiring early, accurate, and reliable reservoir measurements during or after the drilling process.
