  • Publication number: 20190257154
    Abstract: A motorized release device for a downhole device includes one or more dogs disposed within a guide of the downhole device. The one or more dogs may move radially within the guide relative to a central axis of the motorized release device, such that the one or more dogs may move between an engaged position and a disengaged position. The motorized release device also includes a cam that is rotatable about the central axis, such that the cam may move between a locked position and an unlocked position. The cam may block the one or more dogs from moving to the disengaged position while the cam is in the locked position. The motorized release device may also include an electronics board. The electronics board may attach to a motor that rotates the cam between the locked position and the unlocked position.

  • Patent number: 10125545
    Abstract: A manufacturing system that manufactures a downhole tool string, which includes a model that describes relationship between properties of the downhole tool string, properties of a borehole, properties of a formation, and properties of a mud cake formed on a surface of the borehole and a design device that iteratively determines contact parameters that describe one or more contact points expected between the downhole tool string and the mud cake based at least in part on the model, in which the contact parameters comprise contact force expected at each of the contact points, adjusts the properties of the downhole tool string to add a spacer at one of the contact points associated with highest contact force, and indicates location, type, or both of the spacer to enable the manufacturing system to attach the spacer to the downhole tool string before deployment of the downhole tool string in the borehole.

  • Publication number: 20170067299
    Abstract: A downhole roller having a body. The downhole roller also has a wheel connected with the body, and a bearing assembly disposed between the body and the wheel to allow the wheel to move relative to the body. The downhole roller can also have an internal shaft between the wheel and the bearing assembly, wherein the internal shaft holds the bearing assembly in place.

  • Patent number: 8910720
    Abstract: A downhole tool for positioning in a wellbore comprises a tool main body, an electric motor disposed within the tool main body, the motor comprising a rotor rotatably attached to a stator, and a linear actuator assembly disposed within the motor for transforming a rotary output of the motor into a linear displacement.

  • Patent number: 8602115
    Abstract: A tractor configured for grip locking during advancement to avoid slippage, particularly in open-hole wells. The tractor is equipped with a grip lock mechanism for independently locking an anchor grip in a radially outward direction. This locking occurs sequentially in advance of the power stroke of a reciprocating drive piston associated with the anchor. Thus, radial outward expansion and gripping are ensured at the time pulling of a load in an axial downhole direction is pursued. Such grip locking may be employed throughout tractoring or intermittently, depending upon well characteristics such as formation hardness and well diameter.

  • Publication number: 20130248208
    Abstract: Roller devices for passively or actively aiding in the conveyance of a toolstring through a well. The well may be of tortuous architecture and include a host of different corrosives. However, the roller devices are equipped with a cylindrical bearing based mechanism such as a journal bearing. Thus, these devices may be substantially less prone to exposure to corrosives. For example, they may be provided in a substantially monolithic circumferential form more readily shielded and/or isolated from such direct exposure.
