摘要： A method of running a tubular string into a wellbore comprises running a bore-lining tubular string into a wellbore substantially without rotation, while rotating a cutting structure at a distal leading end of the tubular string. Other methods provide for rotation of the string and the provision of a non-rotating stabiliser towards the leading end of the string.

摘要： In one embodiment, there is provided a system for liner drilling in a wellbore that includes a drill bit, a mud motor, a reamer, a drill pipe work string including an expandable liner hanger running tool, and a thruster coupled to an expandable liner hanger and liner. A release pin may be provided in the expandable liner hanger running tool that can be sheared to de-couple the expandable liner hanger from the expandable liner hanger running tool allowing the drill pipe work string to be removed from the borehole while the liner remains in place. A latch coupling is also provided for coupling the expandable liner hanger running tool to the expandable liner hanger when the drill pipe work string is tripped back into the borehole so the liner drilling can be performed using the thruster until the thruster is at full stroke.

摘要： In order to avoid disadvantages of known approaches while maintaining monitored and controlled laying of a pipeline (3) in a borehole (1) and in particular to provide a method and a device for laying a pipeline (3) in a borehole (1), in which large working areas are not necessary either at the starting point or at the end point, in which the number of working steps is reduced compared with the HDD method, and the efficiency of which is improved compared with the MT method, a device for laying a pipeline (3) in a borehole (1) is proposed, having a drill bearing (8), which is couplable to a drill pipe (6) in order to absorb a compressive force acting in the direction of a longitudinal axis of the drill pipe (6) and is connectable to the pipeline (3) in order to transmit the compressive force as a tensile and/or compressive force acting in the longitudinal direction of the pipeline (3), having a drill motor (7), which is angled or anglable with respect to the longitudinal axis of the drill pipe (6), for a drill head (2), said drill motor (7) being provided to drive the drill head (2) independently of a rotation of the drill pipe (6), having a position determining unit (13, 16) for determining and transmitting a rotational position of the angled drill motor (7), and having a control pipe (18), which at least partially encloses the drill motor (7), wherein the drill head (2) extends out of the control pipe (18) in the direction of a working face (19) during operation.

摘要： A completion system (10) comprises tubular components (22) coupled together to form a completion string (24). In-flow control devices (34) are provided to permit selective fluid communication between an internal bore (26) of the completion string (24) and the annulus (28). A reaming tool (38) is provided at a leading end of the completion string (24) and the reaming tool (38) is run into the borehole (12) with the completion string (24). The reaming tool (38) comprises a fluid-powered drive unit (40), a reaming body (42) and a reaming nose (43). In use, the string (24) is located in the borehole (12) and fluid is directed to the reaming tool (38) to facilitate reaming of the borehole (12). A second tubular in the form of a washpipe (44) extends through the internal bore (26) of the completion string (24) for providing fluid to the reaming tool (38). The reaming tool (38) is operable at a fluid pressure below a pressure which would activate the in-flow control devices (34).
