    摘要: Lateral access control in downhole window joint is provided via a window joint. The window joint includes an interior cavity with a first end and a second end opposite to the first end, a first opening defined at the first end, and a lateral opening through a wall of the window joint and into the interior cavity between the first end and the second end. The window joint also includes a deflector where, in a first state, the deflector permits access between the first end and the second end and, in a second state, the deflector blocks access between the first end and the second end and permits access between the first end and the lateral opening by deflecting an object travelling through the lateral opening. The window joint also includes an access control system configured to transition the deflector between the first state and the second state.

    摘要: Methods and systems are provided for automated closed-loop control of drilling trajectory during directional drilling, which define target inclinations and/or target azimuths for a sequence of automated control loops performed over distances of measured depth during directional drilling, wherein the sequence of automated control loops transition from drilling a curve or bend in a wellbore to drilling a horizontal or lateral section or tangent section of the wellbore. In embodiments, the sequence of automated control loops can be configured to incrementally change dog leg severity of the wellbore in a pre-defined manner with the final dog leg severity being at or near zero.

    摘要: Various apparatus, a wellbore string incorporating the apparatus, and a computer-implemented method are described, whereby in various examples at least one flexible elongate member is guided from a wellbore string toward a wall of the wellbore for forming at least one lateral bore in a subsurface rock formation for stimulating the formation. The apparatus in such examples has at least one controllable body which is controllable, based upon a detected downhole configuration of the controllable body and/or the wellbore string, to be positioned with respect to the wellbore string for providing at least one exit through which the flexible elongate member is extractable from the wellbore string for extracting the flexible elongate member through the exit in a desired and/or preferred direction.
