Abstract: High intensity ultrasound is used for pipeline obstruction remediation. Ultrasound transducers are positioned around an outside of the pipeline. The transducers transmit acoustic energy into the obstruction. The acoustic energy heats the obstruction at a location spaced away from the walls of the pipeline. As the obstruction heats, an opening may be formed in the obstruction, relieving pressure build-up without releasing the plug.

Abstract: A system for imaging characters on a surface of an object through a coating on the object includes one or more infrared (IR) radiation sources disposed to irradiate IR radiation upon a object, an IR camera disposed to received IR radiation reflected from the surface of the object, the IR camera adapted to create a digital image of the surface of the object from the received IR radiation, and a computing device in signal communication with the IR camera adapted to receive the digital image of the surface of the object from the IR camera, in which the computing device has installed therein optical character recognition (OCR) software adapted to detecting and recognizing characters imprinted upon the surface of the object.

Abstract: For pipeline inspection, a small, untethered capsule (a “piglet”) images from within a pipeline. The capsule is small enough that rotation about any of three orthogonal axes while within the pipeline is possible. Movement both along the pipeline and perpendicular to the longitudinal axis is possible. To assure images of the pipeline without viewing gaps, the field of view for imaging surrounds the capsule without a gap. Given the possible rotation and translation, the captured images may be motion compensated to provide oriented images of a length of the pipeline.

Abstract: A method for cement bond logging and targeted intervention, including lowering a cylindrical n×m array of ultrasound (US) transducers into a well, firing the US transducers to transmit US signals into a well casing, converting reflected US signals received by the transducers into electronic form and transmit the converted signals to a control unit, analyzing the converted signals to detect holidays, if a holiday is detected, determining a position and angle of the holiday with respect to the transducers, and applying a high intensity focused ultrasound (HIFU) signal to the well casing to fill the holiday.

Abstract: Systems and methods supplementing existing management methods to corroborate performance of a blow out preventer for a submerged well. The corroborator is located on the blow out preventer and includes a flow meter external to a pipe to measure flow inside the pipe, a pipe joint locator, a ram seal confirmation agent and a dedicated communication connection from the corroborator to a computer topside. Data from at least one sensor topside, which may represent a mud tank level, is also received. The computer calculates a probability that a malfunction related to the well occurs. The computer implements a Principal Component Analysis model of the well based on historical data, to assess a likelihood that a threshold value will be surpassed based on collected sensor data and to generate an alert.
