Triple Tube Core Barrel

Triple Tube Core Barrel is used for exploration of dams, bridges, geotechnical investigation, diamond core drilling, soil investigation, testing of foundation of the high rise buildings as well as mineral exploration for obtaining nearly 100% core recovery. After the triple tube barrel has been retrieved from the drill hole the reaming shell, diamond core bit and core lifter case are removed.


These triple tube core barrel are generally used for geotechnical purpose,designed to maximize core recovery in soft formations.Available diameter sizes from 35-146mm. Wireline double core barrels are primarily used in deep coring.With an overshot device,they eliminate the need to couple and uncouple the rod string each time the core is retrieved.

Triple Tube Core Barrels are normally supplied with stainless steel split inner tubes. Clear plastic tubing is available in NMLC size. The plastic tubing is used when retaining the core exactly as it is recovered from the hole is desired. The core is left in the tube and the ends are sealed. Visual examination is possible through the tubing on site or at the laboratory.

The Triple Tube TSS corebarrel forms the basis of our barrel system that incorporates an innovative three-barrel system compared to traditional inner/outer barrel systems. TSS eliminates thermal expansion issues, improves core quality through ease of handling, and provides a platform to enhance wellsite processes and core analysis. The TSS includes two components, a threaded steel jacket and a disposable liner in which the core is housed. The presence of two independent tubes allows the disconnection process to take place without transmitting the torque to the core, therefore without inducing any rotation core damage.
