    Abstract: In another embodiment, a method of drilling a wellbore includes running a drilling assembly into the wellbore through a casing string, the drilling assembly comprising a tubular string, an underreamer, and a drill bit; injecting drilling fluid through the tubular string and rotating the drill bit, wherein the underreamer remains locked in the retracted position; sending an instruction signal to the underreamer via modulation of a rotational speed of the drilling assembly or modulation of a drilling fluid pressure, thereby extending the underreamers; and reaming the wellbore using the extended underreamer.

    Abstract: A method of drilling a wellbore includes running a drilling assembly into the wellbore through a casing string, the drilling assembly having a tubular string, a stabilizer, and a drill bit; applying a force to an arm of the stabilizer, thereby causing the arm to retract; and removing the stabilizer and the drill bit from the wellbore.

    Abstract: A method of drilling a wellbore includes drilling the wellbore by injecting drilling fluid through a drill string extending into the wellbore from surface and rotating a drill bit of the drill string. The drill string further includes a circulation sub having a port closed during drilling. The drilling fluid exits the drill bit and carries cuttings from the drill bit. The drilling fluid and cuttings (returns) flow to the surface via an annulus formed between an outer surface of the tubular string and an inner surface of the wellbore. The method further includes after drilling at least a portion of the wellbore: halting drilling; sending a wireless instruction signal from the surface to a downhole portion of the drill string by articulating the drill string, acoustic signal, or mud pulse, thereby opening the port; and injecting drilling fluid through the drill string and into the annulus via the open port.

    Abstract: Methods and apparatus are provided to place a conductor pipe and a casing in a subsea environment. In one embodiment, a conductor pipe is jetted or drill ed into the subsea floor. Thereafter, a casing drilling assembly comprising a drill casing and a drilling assembly is connected to the drill pipe using a crossover. The drilling assembly urged into the seafloor until a casing latch on the drilling assemb ly is engaged with a casing profile of the conductor pipe. During drilling, instrumentation in the drilling assembly may be used to measure geophysical data. The measured data may be used to optimize the drilling process. After the drill casing is engaged with the conductor pipe, cementing may be performed to set the drill casing.

    Abstract: A controller for operating a downhole tool includes a tubular body; a seat disposed in the body for receiving first and second pump-down plugs, at least a portion of one of the seat and the plugs being radially displaceable to pass through or allow passage of the other at a first threshold pressure differential; a catcher located below the seat for receiving the plugs after passing through the seat; a toggle linked to the seat to alternate between a locked position and an unlocked position in response to seating of the plugs; and a control mandrel for engaging a piston of the downhole tool and linked to the toggle: to be longitudinally movable between a first position and a second position when the toggle is unlocked, and to be prevented from movement from the first position to the second position when the toggle is locked.
