Corpro Core Barrel technology debuts in the Gulf of Mexico for
Ultra Deepwater Operations Oil/Gas Drilling
Corpro's core barrel technology debuts in the Gulf of Mexico
Corpro is now deploying its innovative Thin Sleeve System Core
Barrel technology into the Gulf of Mexico.
Initiating its presence only late spring, Corpro has already
completed three ultra deepwater operations in the Gulf of Mexico
and is proud of the quality and integrity of the core samples that
were delivered. Nearly half of all onshore and offshore core
cutting activities within the global energy industry are carried
out under Corpro, however this is the first year the company’s
technology has been used in the Gulf of Mexico.
Roschen Core Barrels
Advanced Core Barrel Technology
Roschen have been operating with predominantly the same technology for over 40 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.
Core Barrel Range:

Thread Type | ROSCHEN HD | ROSCHEN HD | ROSCHEN HD | ROSCHEN HD | ROSCHEN HD | |
Rec. Hole Size | (in) | 5 3⁄4 - 61⁄2 | 6 1⁄2 - 8 | 8 - 9 1⁄4 | 9 1⁄4 - 11 | 11 - 12 1⁄4 |
Core Size | (in) | 2 9⁄16 | 3 1⁄2 | 4 | 5 1⁄4 | 5 1⁄4 |
Top Connection | 3 1⁄2 IF | 4 1⁄2 FH | 4 1⁄2 IF | 6 5⁄8 REG | 6 5⁄8 REG | |

Unit Length | (in) | 20 | 20 | 20 | 20 | 20 |
Pulling Capacity | (lbs) | 300000 | 515000 | 860000 | 960000 | 1550000 |
Make-Up Torque | (ft lbs) | 7500 | 9500 | 30000 | 35000 | 45000 |
Max. Torque | (ft lbs) | 25000 | 35000 | 70000 | 75000 | 120000 |
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
