Casing Advance System
CENTER ROCK INC.’s Casing Advance system is about to change everything. The Casing Advance System offers greatly reduced casing friction, the elimination of the need for cutter teeth on starter casings, and faster penetration through difficult overburden.
Key Features & Benefits of the Casing Advance System
The Casing Advance System is an overburden drilling system for casing advancement developed by CENTER ROCK, INC.® With wings that lock in place and are easily retractable, the Casing Advance System is able to drill straight, full-diameter holes through any formation, including pinnacle limestone and karst. The lack of expensive starter casing J-teeth or ring bits needed means your team saves money by using the Casing Advance System.
As the pilot bit rotates and makes contact with the ground, the system rotates into a locked position, and the wings are fully extended. While in this position, the wings are positively locked, ensuring that the pilot will drill a borehole to a fully expanded diameter until retracted.
The long nose on the pilot leads/guides the tooling through sloping and karstic formations, maintaining the desired angle and minimizing deviation. When the target is reached, with a slight bump backward, the system moves to the retracted position, allowing the wings to collapse inward. At that point, the bit is retracted from the casing, leaving the casing behind.
The Casing Advance System is the ultimate underreamer system. It delivers straighter holes, minimizes casing friction, which can cause casing failures, requires NO expensive casing teeth, and provides industry-leading penetration rates.
