    Abstract: The present disclosure relates generally to a well boring apparatus, and associated components, for drilling wellbores without the necessity of traditional well drilling equipment. The well boring apparatus operates on similar principles as a tunnel boring apparatus. The well boring apparatus is self-propelled, steerable, and can be launched from a topside vessel or directly from a seabed installation. The well boring apparatus is fully instrumented and capable of analyzing the surrounding environment including the temperature, pressure, acidity and the presence of particular chemicals. The well boring apparatus is highly modular such that it can be configured for different tasks. The well boring apparatus can include components to case/line the wellbore during drilling, eliminating the need for running casing/lining. Further, the well boring apparatus can be incorporated in a drilling system in which cuttings are processed at the seabed, thereby removing the need for a drilling riser.

    Abstract: The present disclosure generally relates to an assembly and method for monitoring the position of one or more opposing rams in a rain-type blowout preventer (“BOP”) during opening and closing operations. In particular, a BOP includes a vertical bore extending through the body, a rain cavity intersecting the bore, and a port located below the rain cavity. A sensor assembly is locatable in the port and is configured to monitor the position of at least one opposing rain contained in the BOP. At least one of the rams includes a detection feature on a lower surface of the rain which is distinguishable from the rest of the rain body, other features of the BOP, and any debris in the bore of the BOP. The detection feature is detectable by the sensor assembly. The detection feature may include a visual indicator.

    Abstract: An apparatus for characterizing objects in the bore of a well assembly is provided. In one embodiment, the apparatus includes a sensing array including ultrasonic transducers and a data analyzer coupled to receive input from the sensing array. The sensing array is positioned to transmit ultrasonic waves into the bore of a well assembly and to receive ultrasonic waves from the bore. The data analyzer processes data representative of ultrasonic waves received by the sensing array to identify a location of a component in the bore. Additional systems, devices, and methods are also disclosed.

    Abstract: A system for determining the location of a piston within an accumulator is provided in which a short circuit is created between elements in the accumulator and the piston which is movable within the accumulator. As the piston moves along the longitudinal axis of the accumulator, the circuit's electrical characteristics (e.g., voltage, resistance, current) vary in accordance with the length of the circuit. Measurement of these electrical characteristics allows for precise determination of the piston location relative to the accumulator. In a commercial embodiment, the invention can be utilized to determine fluid volumes in an accumulator by monitoring the location of the piston. This invention overcomes prior art systems because, inter alia, it does not require electrical sensory equipment, enables remote monitoring, maintains system integrity and functions irrespective of container wall thickness.
