Security DBS Drill Bits, a product line of Halliburton’s Drilling and Formation Evaluation Division, announced a breakthrough technology to its suite of Hole Enlargement products and solutions. The XR™ reamer line of tools is designed for both conventional and rotary steerable applications and it provides the industry’s only available concentric hole enlargement technology that is also capable of enlarging a pilot hole more than 40 percent while drilling.
XR reamer tools offer activation and deactivation capabilities that allow the hole to be selectively enlarged based on existing casing-shoe and well-design parameters.
By integrating Security DBS’ advanced bit and reamer technologies with Sperry Drilling Services’ Geo-Pilot® system, Halliburton delivers reliable hole-enlargement solutions with proven results. In one well, the XR 1200 reamer, in combination with the Geo-Pilot and FullDrift® bit-matched system, enabled Halliburton to drill ahead and enlarge a 700-meter section of Cretaceous chalk with hard stringers from 12-1/4 in. to 17-1/2 in. in less than 72 hours. In a Norwegian offshore well, the XR 1200 reamer established the longest simultaneous 12-1/4-inch hole opening run, drilling 4,661 m at an 80-degree inclination.
