    Abstract: In one aspect, the disclosure provides a method of drilling a wellbore, which method, in one embodiment, includes the features of drilling the wellbore with a drill string that includes a bypass device having a fluid passage therethrough by supplying a fluid through the bypass device, wherein the drilling fluid circulates to the surface via an annulus between the drill string and the wellbore; defining a time period (locking time); initiating a selected drilling parameter; detecting downhole the selected drilling parameter and one of the second flow rate and a differential pressure; and activating the bypass device when the selected drilling parameter and one of the second flow rate and the differential pressure are present during the defined time period to divert a portion of the drilling fluid from the bypass device to the annuls. In one aspect, the selected drilling parameter is rotation of a member associated with the bypass device.

  • Patent number: 9097065
    Abstract: A method of designing an earth-boring rotary drill bit includes designing a bit body and cutting elements of the drill bit such that features of the drill bit other than cutting elements engage and rub against a subterranean formation being drilled by the drill bit at depths-of-cut beyond, but close to, an intended median depth-of-cut, and such that the amount of rubbing area between such features and the formation increases at a relatively rapid rate as the depth-of-cut increases beyond the intended median depth-of-cut. Such methods may be employed to mitigate the occurrence of the “stick-slip” phenomenon during drilling. A method of fabricating a drill bit includes configuring a bit body and cutting elements in accordance with such a design. Earth-boring drill bits include a bit body and cutting elements so configured.

  • Patent number: 9033067
    Abstract: A vibrational tool and method is disclosed, which may be utilized to assist in lowering a drill string into a wellbore. In one embodiment, a reciprocating member and a symmetrical rotating member are mounted within a vibrational tool housing. The reciprocating member is urged in one embodiment by a spring assembly toward the rotating member whereby engagement surfaces on the reciprocating member and rotating member encounter each other. As the rotating member rotates, variable surfaces on the engagement surface cause the reciprocating member to reciprocate as the variable surfaces follow or cam with respect to each other during rotation. The resistance to rotation by engagement surfaces and spring assembly, and mass of the rotating member, result in vibrational forces, when drilling fluid flows through the vibration tool housing.
