20150047912 | DRILL BIT AND CUTTERS FOR A DRILL BIT - In a fixed cutter drill bit, a hybrid cutter with a cutting edge including a substantially continuous curve interrupted by at least one arc discontinuity. In a fixed cutter drill bit, a contoured cutter with a contoured cutting face including a raised shape, wherein the raised shape has a raised shape axis which is oblique to a drill bit body axis. In a cutter for a fixed cutter drill bit, a chamfer including a side bevel and a cutting face bevel, wherein a cutting face bevel length is at least two times a side bevel length. | 02-19-2015 |
20140246234 | DRILLING APPARATUS AND METHOD - A drilling apparatus including a drill bit and a nutation device. The drilling apparatus is configured to enable the drill bit to be rotated at a rotation frequency while the nutation device simultaneously nutates the drill bit at a nutation frequency. The nutation device may include a vibrating device for imposing vibrations upon the drilling apparatus at a vibration frequency, thereby causing nutation of the drill bit at the nutation frequency. The drilling apparatus may include a tuning mechanism for tuning the vibration frequency of the vibrating device. A method including rotating a drill bit at a rotation frequency and simultaneously nutating the drill bit at a nutation frequency. | 09-04-2014 |
20130341099 | DOWNHOLE MOTOR ASSEMBLY - A downhole motor assembly including a housing, a power section with a stator and a rotor contained within the housing, a proximal drive assembly connected with a proximal rotor end, a distal drive assembly connected with a distal rotor end, a proximal thrust bearing arranged between the housing and the proximal drive assembly, a distal thrust bearing arranged between the housing and the distal drive assembly, and an axial load decoupling device in the distal drive assembly located longitudinally between the distal rotor end and the distal thrust bearing, for separating axial loads imposed on the proximal thrust bearing from axial loads imposed on the distal thrust bearing. | 12-26-2013 |
20120228035 | DRILLING APPARATUS - A drilling apparatus including a housing, a drill bit having a head end, a connection end, and a bearing mandrel between the head end and the connection end, a bearing pack associated with the bearing mandrel and the housing for transmitting forces between the drill bit and the housing, the bearing pack including at least one bearing interposed between the bearing mandrel and the housing, and a drive mechanism connected with the connection end of the drill bit, for driving the drill bit. | 09-13-2012 |
