    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: A method and apparatus (100) for removing debris from a wellbore using a cleaning tool. The tool may comprise an inner mandrel (17) and a cup member (20) coupled to the inner mandrel. The cup member is moveable between a collapsed position where fluid may flow across the exterior of the cup member, and an extended position where fluid is diverted into a flow path disposed between the inner mandrel and the cup member. The fluid is diverted through a filter member (30) that is coupled to the inner mandrel below the cup member.

    Abstract: A tachometer for a downhole motor includes: a tubular housing having a coupling for connection to a housing of the motor; and a probe. The probe: has a coupling for connection to a rotor of the motor, is movable relative to the tachometer housing, and has at least a portion disposed in a bore of the tachometer housing. The tachometer further includes electronics disposed in the tachometer housing and including: a battery; one or more proximity sensors for tracking an orbit of the probe; and a programmable logic controller (PLC). The PLC is operable: to receive the tracked orbit, and at least one of: to determine an angular speed of the probe using the tracked orbit, and to forecast a remaining lifespan of the motor using the tracked orbit.
