The Avalanche is an on-demand downhole, hydraulically-actuated stabilizer. Designed for use in a 2D directional drilling application to help control the inclination in an extended reach or horizontal well, the Avalanche can be utilized in a conventional rotary bottom hole assembly, or positioned above or below a steerable motor. The gauge diameter of the stabilizer is controlled remotely by the pumps on surface. Our patented design allows drillers to select the diameter of the tool while downhole and continue drilling while remaining in a specific mode, even through regular connection processes. This saves time and money and is further advanced technology than previous versions.
The unique blade geometry of the Avalanche makes it the only downhole adjustable stabilizer that combines ease of sliding when run above a motor, with improved cuttings transport when rotating. With the updated internal cam design, the Avalanche can remain in a specific mode without multiple pump cycles, further saving downtime.
