Deliver a smooth and unobstructed wellbore. Improve drilling and completions operations.
The GunDRILLTM Reamer is one of our most flexible products. Depending on the job requirements, it can go uni-directional for back reaming, bi-directional for back and front reaming, or if sliding is expected, it offers a directional variant with flat TCIs. Rubicon’s GunDRILLTM Reamer utilizes a simple blade design that uses proprietary Tungsten Carbide Inserts (TCI) that provide more reaming or stabilization according to the drilling and formation conditions and maintains the gauge for extended durations. The GunDRILLTM Reamer uses the drilling BHA to improve hole shape, smoothness and quality. PDC cutters on a beveled profile help maintain gauge of wellbore in cases of severe swelling and/or borehole instability.
Making it better
The GunDRILLTM Reamer reduces torque compared to the fixed blade stabilizers.
Rotate the provided string to grant added security against sticking downhole. Allows holes to be re-opened to avoid having stuck pipe due to borehole problems. Reduce NPT related to POOH. Lessens heavy back reaming in mobile and transient formations.
