Paper presented at the IADC/SPE Drilling Conference, March 4–6, 2008
Paper Number: SPE-112650-MS
..., including rotary steerables, bi-center bits, roller-reamers, hole openers, and eccentric mass stabilizers. Modeling results have been validated in large, intermediate, and small hole sizes. In these applications, predicted behavior and field observations have compared well. Redesign has resulted in improved...

... of the new PDC designs contained new features to significantly improve directional characteristics. A variety of other improvements/modifications are mentioned in the paper. Results: The new technology bi-center bits (17 × 20 and 14 ½ × 17 ½), provided the biggest time savings by eliminating trips...

... weight and fracture gradient at the deepwater Ursa site combine to require drilling a larger sized hole than the drift diameter of the previous casing string for all of the casing intervals. Bi-center bits have successfully drilled all of the intervals in one run except the section to total depth (TD...

Paper presented at the IADC/SPE Drilling Conference, February 23–25, 2000
Paper Number: SPE-59239-MS
... Abstract In 1994, bi-center bits were introduced which contained new technology. For the first time, a single tool could reliably be used to simultaneously drill and underream, even in highly directional applications, all with no moving parts. The results were fewer trips, fewer rotating hours...

... ABSTRACT This paper describes the design and application of new bi-center bit technology in the Bay Marchand Field (offshore Louisiana). A bi-center bit and tandem motor assembly were used to simultaneously drill, underream, and directionally control a slim hole horizontal re-entry well using...

Paper Number: SPE-23869-MS
... Abstract The first polycrystalline diamond compact (PDC) bi-center bit application in California reduced cost per foot and helped eliminate tight hole problems associated with Pliocene age overpressured swelling shales. The bi-center bit design drills a larger hole than the casing inner...
