    摘要: In one embodiment, a top drive system for drilling with casing is provided with an access tool to retrieve a downhole tool. The top drive system for drilling with casing comprises a top drive; a top drive adapter for gripping the casing, the top drive adapter operatively coupled to the top drive; and an access tool coupled to the top drive and adapted for accessing a fluid passage of the top drive system. In another embodiment, a method for retrieving a downhole tool through a tubular coupled to a top drive adapter of a top drive system is provided. The method comprises coupling an access tool to the top drive system, the access tool adapted to provide access to a fluid path in the top drive system and inserting a conveying member into the fluid path through the access tool.

    摘要: A method of forming a wellbore includes providing a drilling assembly comprising one or more lengths of casing and an axially retracting assembly having a first tubular; a second tubular at least partially disposed in the first tubular and axially fixed thereto; and a support member disposed in the second tubular and movable from a first axial position to a second axial position relative to the second tubular, wherein, in the first axial position, the support member maintains the second tubular axially fixed to the first tubular, and in the second axial position, allows the second tubular to move relative to the first tubular; and an earth removal member disposed below the axially retracting assembly. The method also includes rotating the earth removal member to form the wellbore; moving the support member to the second axial position; and reducing a length of the axially retracting assembly.
