Abstract: According to the invention, a method for designing a rotary drill bit for drilling a cavity in a medium is disclosed. The method may include determining a characteristic of a drillstring with which the rotary drill bit is coupled. The method may also include determining an initial number of groups of cutters for the rotary drill bit, where each group of cutters includes a plurality of cutters substantially aligned along a different radius of the drilling face. The method may moreover include determining a characteristic of the medium relative to a characteristic of the cutters. The method may additionally include determining a characteristic of a rotational motion source used to rotate the rotary drill bit. The method may further include determining the angles of pitch between each of the groups of cutters to minimize an amount of sticking or slipping of the bit in the medium during a drilling operation.

Abstract: A first wireline tool embodiment includes a segmented tool body having a joint deployed between each adjacent pair of tool body sections. The joint may be configured to extend axially (causing a relative axial displacement of the adjacent tool body sections) when the wireline tool is subject to an axial load. The joint may include, for example, a compliant joint or a protractible joint. The joint may be further configured to cause a relative rotation between the adjacent tool body sections when the wireline tool is subject to axial load. A second wireline tool embodiment includes a plurality of standoff rings deployed about an outer surface of a rigid tool body. The standoff rings engage helical grooves in the outer surface of the tool body such that axial displacement of the tool body causes the standoff rings to rotate.

Abstract: A technique employs the use of oscillations downhole to facilitate a desired functionality of a downhole tool. According to this technique, a tool is initially conveyed downhole and operated to perform a function that relates to a downhole application. The operational efficiency of the tool is improved by creating oscillating forces which vibrate the tool to achieve a desired result, e.g. freeing the tool from a stuck position.

Abstract: Active stabilization is provided. In one possible implementation a drilling tool associated with a drill bit includes one or more rotation alteration devices configured to alter a rotational radius of a drill string. The drilling tool also includes at least one active stabilizer rotatively attached to the drilling tool, as well as a variable brake configured to control a rotation of the at least one active stabilizer relative to the drilling tool. In another possible implementation, a drilling tool includes an active stabilizer rotatably coupled to the drilling tool, as well as an actuation system configured to control a torque placed on the active stabilizer through contact with a wall of a borehole.

Abstract: Methods and systems relate to a pressure exchanger which exchanges pressure energy from a high pressure clean fluid system to a relatively low pressure harsh fluid system for use in pressurizing the harsh fluid and directing the fluid to a wellbore as high pressure harsh fluid without the harsh fluid contacting identified portions of the pressure exchanger.

Abstract: A valve and seal arrangement for extended life in a positive displacement pump. The arrangement may take on different configurations. The seal may be secured within a shielding sidewall of a valve head for isolation from differential pressure during striking of the valve head at a valve seat. Additionally, the seal itself may include an axial tail for sealing off the fluid chamber below and defined by the seat prior to the striking of the valve head at the seat. Further, a horizontal flange defining a clearance of no more than about a layer of an abrasive constituent of a slurry being pumped may be utilized. That is, as opposed to, or in addition to, sealing in advance of striking, flow may be reduced to no more than a constituent layer thickness in advance of the striking. Other similarly advantageous architectural valve features may also be employed.

Abstract: Systems and methods for evaluating a cement installation are provided. In one example, the cement may be evaluated using a casing arrival measurement sensor that measures casing arrival signals resulting from firing a signal from a cement bond logging acoustic source. External signals (e.g., signals other than the casing arrival signals) may be attenuated by firing an attenuation firing signal.

Abstract: Apparatus and operational methods thereof, including a top drive, a rotation sensor, and a processing device. The top drive connects with an upper end of a drill string. The rotation sensor facilitates rotational distance measurements indicative of rotational distance achieved by the top drive. The processing device causes the top drive to impart rotational oscillations alternatingly in opposing directions to the upper end of the drill string while maintaining a downhole toolface orientation during a slide drilling operation, such that each rotational oscillation rotates the upper end of the drill string through a base rotational distance. The processing device also causes the top drive to change the downhole toolface orientation by an offset rotational distance by adding the offset rotational distance and an overshoot rotational distance to the base rotational distance of an instance of the rotational oscillations.
