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
