  • Publication number: 20150184460
    Abstract: Systems facilitate forming lateral wellbores by optionally eliminating one or more trips downhole. The systems provide for forming a lateral wellbore by enabling the milling of a casing window and/or the drilling of the desired lateral wellbore to a target depth during a single trip down hole. The systems also facilitate improved downhole dynamics control and overall bottom hole assembly functionality.

  • Patent number: 8997895
    Abstract: A system and method to facilitate the drilling of one or more lateral wellbores while eliminating one or more trips downhole. The system utilizes a drilling assembly comprising an impregnated drill bit or other suitable drill bit. The impregnated drill bit is coupled to a whipstock by a connector for deployment downhole in a single trip. The connector comprises a separation device which facilitates disconnection of the impregnated drill bit from the whipstock once the whipstock is anchored at a desired downhole location.

  • Patent number: 8844620
    Abstract: A sidetracking tool includes a setting tool having an expandable anchor, a whipstock connected to an upper end of the setting tool, the whipstock having a ramp face along an axial length thereof, and a drilling assembly including a drill bit disposed on an end thereof, wherein the drill bit is configured to interface with the ramp face of the whipstock.

  • Patent number: 8820437
    Abstract: A technique facilitates sidetracking by eliminating one or more trips downhole. The technique comprises delivering a sidetracking system downhole into a wellbore, and utilizing a component of the sidetracking system to grip a wall of the wellbore. The sidetracking system may comprise a whipstock assembly and a running/stinger assembly in which the stinger assembly is designed for disconnection from the whipstock assembly after delivery downhole. After disconnecting the stinger assembly, the sidetracking system enables delivery of cement slurry down through the stinger assembly to form a cement plug at a desired location.

  • Publication number: 20140216819
    Abstract: A system and method facilitate drilling of a lateral wellbore by eliminating one or more trips downhole. The system comprises a drill bit optimized for the drilling operation. The drill bit is coupled to a whipstock via a connector, which minimizes interference with the cutting elements of the drill bit. The connector includes a separation device which facilitates disconnection of the drill bit from the whipstock after the whipstock is anchored at a desired downhole location. The separation device is disposed in the connector to minimize the remaining portions of the connector existing after separation of the drill bit from the whipstock which must be milled by the drill bit prior to drilling the lateral wellbore.
