AMSTERDAM -- Security DBS Drill Bits, a product line of Halliburton's Drilling and Formation Evaluation Division, announced yesterday at SPE/IADC in Amsterdam that it has added 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. According to Halliburton, it provides the industry's only available concentric hole enlargement technology that is also capable of enlarging a pilot hole more than 40% while drilling.
The XR reamer tools also offer activation and deactivation capabilities that allow the hole to be selectively enlarged based on existing casing-shoe and well-design parameters.
"Hole enlargement is expected to grow more than 40% in 2007 to an estimated 16% of total footage drilled worldwide," said James Bement, VP, Security DBS Drill Bits. "This development reflects an overall systems approach to meeting this challenge in increasingly complex drilling applications."
In one well, the XR 1200 reamer, in combination with Sperry Drilling Services' Geo-Pilot and FullDrift bit-matched system, enabled Halliburton to drill and enlarge a 700-m (2,297-ft) section of Cretaceous chalk with hard stringers from 311.15 mm (12 ¼ in.) to 444.5 mm (17 ½ in.) in less than 72 hours.
In a Norwegian offshore well, the XR 1200 reamer established the longest simultaneous 311.15 mm (12-1/4 in.) hole opening run, drilling (4,661 m) 15,291 ft at an 80° inclination.
