    Abstract: A method includes introducing a drill string including a bottom hole assembly into a wellbore, wherein the bottom hole assembly includes a mounted 3D printing sub-assembly. A wellbore is drilled with the bottom hole assembly, and at least a portion of a casing is printed with the 3D printing sub-assembly while drilling the wellbore. A related system includes a drill string having a length of drill pipe and a bottom hole assembly disposed at a distal end of the length of drill pipe. A 3D printing sub-assembly is mounted on the bottom hole assembly, wherein the printing sub-assembly includes a printer housing and a 3D printing head mounted at the printer housing. A control guides the 3D printing head to print at least a portion of a casing at a location radially away from the central longitudinal axis of the drill string.

    Abstract: A rig site may include a rotary table within a rig floor above a wellbore. A fabric sheet rolled into two symmetrical rolls is disposed on the rig floor. A pre-cut center hole of the fabric sheet is coaxial with the rotary table. A casing string, to be lowered in the wellbore, includes a first casing joint at a bottom of the casing string is a modified float joint. The pre-cut center hole of the fabric sheet is attached to a sleeve of the modified float joint. Union units are provided above the rotary table. The union units close the fabric sheet around the casing string to form a fabric-nested casing string within the wellbore. A cement slurry is pumped down the casing string and into a space between the fabric sheet and the casing string to cement the fabric-nested casing string to the wellbore.

    Abstract: A downhole autonomous jet cutting tool includes a main body with a generally cylindrical configuration. The main body includes a locking unit actuable to engage the tool to an inner surface of the pipe, a hydraulic motor with a rotor and a stator, and a rotatable jet cutting nozzle assembly operable to emit a stream of fluid to cut the pipe. The tool also includes a sensor module to detect interactions between the pipe and walls of the wellbore and a control unit in electronic communication with the sensor module and the locking unit. The control unit can identify, based on output of the sensor module, a location where interaction between the pipe and the walls of the wellbore limits downhole movement of the pipe, actuate the locking unit to engage the tool in the inner surface of the pipe, and initiate the stream of fluid from the nozzle assembly.
