    摘要： Apparatus and methods for selectively releasing a first wellbore component to a second wellbore component using a disconnect device. The method includes coupling a disconnect device to a workstring and a downhole tool; performing a downhole operation using the downhole tool, and selectively releasing an upper portion of the disconnect device from a lower portion of the disconnect device, thereby releasing the downhole tool from the workstring. The method may also include reconnecting the upper portion of the disconnect device to the lower portion of the disconnect device. The disconnect device is capable of transferring torque to the wellbore component.

    摘要： The present invention generally relates to an apparatus and method of jarring with an overpull generator. In one aspect, a method of dislodging an object stuck in a wellbore is provided. The method includes the step of running an assembly into the wellbore on a conveyance member and attaching the assembly to the object, wherein the assembly comprises an overpull generator and a delay force release device. The method also includes the step of generating an overpull force in the wellbore by selectively activating the overpull generator. Additionally, the method includes the step of applying an impact force to the object by activating the delay force release device and releasing the generated overpull force, thereby dislodging the object stuck in the wellbore. In a further aspect, an assembly for dislodging an object stuck in a wellbore is provided. In yet a further aspect, an overpull generator for use in generating an overpull force in a wellbore is provided.

    摘要： The present invention discloses a whipstock assembly (100) for use in forming a lateral borehole from a parent wellbore. The whipstock assembly comprises a body (122) and a deflection member 120) above the body. The deflection member includes a concave portion (111) for deflecting a milling bit during a milling operation. Disposed on a perforation plate (110) portion of the concave portion is a raised surface feature (116). The raised surface supports a milling bit above the perforation plate portion during a milling operation. This, in turn, substantially prevents frictional contact between the milling bits and the perforation plate portion during a milling operation. The present invention also provides a novel method for manufacturing a whipstock in which a cavity portion is formed behind the perforation plate by milling out the backside of the deflection member and then joining a second back cover member to the whipstock body to complete the assembly.

    摘要： A drill pipe includes one or more sections which are strengthened, or their shape is altered, in order to improve the wear and buckle resistance of the drill pipe. The sections are strengthened using various hardening methods such as heat treatment processes and/or expansion techniques. A sleeve can also be applied to the strengthened portions. Surface enhancers, such as hardbanding, can be applied to the strengthened portions or the sleeve in order to provide abrasion resistance or to reduce friction.
