Drilling

Hole Opening Technology

The ability to drill cement and associated downhole float equipment with eccentric tools has become increasingly important in deep water Gulf of Mexico drilling. The extra trip required by conventional eccentric tools can add significant cost to a well.

Hughes Christensen recently introduced a modified Steerable Ream While Drilling (DOSRWD) system that has demonstrated the ability to successfully drill-out all types of float equipment. HCC's DOSRWD features a field exchangeable pilot bit so the tool can utilize standard Tricone or PDC to optimize performance in a particular formation.

Together, our Ream While Drilling (RWD) tool, Steerable Ream While Drilling (DOSRWD) tool and the Slimhole Technology Ream While Drilling (STRWD) tool comprise a system designed for specific hole opening applications at a fraction of the costs and none of the risks associated with bi-center bits and conventional under reamers.
