Triple Core Barrel CORPRO Triefus Triple Tube Core Barrel for Coring tool with TSS
Advanced Core Barrel Technology
ROSCHEN Coring companies have been operating with predominantly the
same technology for over 50 years. ROSCHEN identified this and
seized the opportunity to develop a pioneering new coring system.
This new innovative coring system, utilizing improved materials
technology, has set and maintained benchmark standards for coring
in the petroleum industry.
The ROSCHEN coring concept has been specifically designed to enable
the retrieval of longer, higher quality cores. The new system
features four primary benefits:
• faster rates of penetration
• less incidence of core jamming
• increased reliability
• improved core quality
ROSCHEN believes that correct stabilization is one of the most
important factors governing a successful coring operation. Without
the outer barrel properly stabilized, bending within the well bore
is imminent.
ROSCHEN researched the positioning of its stabilizers and
determined that optimal stabilization could be achieved using core
barrels in 20 ft stabilized sections. For high angle and horizontal
holes, a stabilizer can be placed midway in the lower section,
giving three stabilizers within the bottom 20 ft.

Benefits:
• Transfer of power through core-barrel to core-head without losses
due to buckling
• Higher torsion and tensile strengths than any alternative systems
in the market place
• Stabilizers positioned at 20ft intervals improve hole gauge and
concentricity
• ROSCHEN Tandem and Extended Tandem Assemblies promote increased
success in high angled wells
