Proceedings Papers

Paper presented at the Abu Dhabi International Petroleum Exhibition & Conference, November 11–14, 2019
Paper Number: SPE-197542-MS
... recent studies show that drilling bits play an important role in drilling optimization and help to overcome most of the challenges connected with the rock destruction process and tool lifecycle. In recent years, 3D PDC cutters such as ridge diamond elements (RDE), rolling PDC cutters (RC), and conical...

Paper presented at the Abu Dhabi International Petroleum Exhibition & Conference, November 11–14, 2019
Paper Number: SPE-197735-MS
... proposed solution of hybrid bit design by combining conical (CDE) and ridged (RDE) diamond elements. Two new hybrid 8-bladed 16-mm bit were specifically designed for this application. The first bit drilled an interval of 952m with an average ROP of 1.9m/hr and the second bit drilled an interval of 960m...

... innovate cutter shapes and 3D surfaces to interact with the rock. A new hyperbolic diamond element (HDE) bit has been developed to improve drilling efficiency in soft formations compared with conventional polycrystalline diamond compact (PDC) cutters. The design concept and bit utilization theory...

... to losses when present. Positive AOR feedback and continuous development from the service company resulted in further improvements to the PDC bit design with the introduction of ridged diamond elements and the latest generation conical elements to further improve steerability and ROP.
