Product Description

Advanced API Oil Core Barrel Technology

ROSCHEN developed this pioneering coring system using advanced materials technology to set benchmark standards for petroleum industry coring operations. The system is engineered to retrieve longer, higher quality cores with superior performance.

Primary System Benefits

Faster rates of penetration for improved operational efficiency
Reduced incidence of core jamming for continuous operation

Technical Advantages

Efficient power transfer to core-head without buckling losses
Superior torsion and tensile strength compared to alternative systems
20ft interval stabilizers for improved hole gauge and concentricity
Tandem and Extended Tandem Assemblies for high-angle well success

Stabilization Excellence: ROSCHEN research determined optimal stabilization using 20ft stabilized sections. For high angle and horizontal holes, additional stabilization provides three stabilizers within the bottom 20ft section.
