The coupon can be automatically applied to purchases made by the same user and/or other users, as applicable.

Abstract: Methods to improve fluid flow of a multi-phase mixture, methods to separate fluids of a multi-phase mixture, and downhole multi-phase fluid mixture systems are disclosed. A method to improve fluid flow of a multi-phase mixture includes positioning a first acoustic device and a second acoustic device around a conveyance that provides a fluid flow path for a first fluid in a first phase and a second fluid in a second phase to simultaneously flow through the conveyance. The method also includes determining a flow rate and a fluid condition of the fluid mixture. The method further includes generating a standing acoustic wave through the conveyance based on the flow rate and the fluid condition to break down the first fluid into droplets having volume within a threshold volume.

Abstract: A downhole shunt tube isolation system includes an isolation sleeve housing defining an isolation sleeve chamber and an isolation sleeve moveable within the isolation sleeve chamber between an open position and a closed position.

Abstract: A method of operating a wind energy installation wherein a rotor has a first rotor blade which can be angularly adjusted, a first adjustment drive for adjusting the rotor blade, and a safety control system. In a normal mode of operation, the first adjustment drive is supplied with energy from a source and is controlled by a first pitch control system. In a failure mode of operation, the supply of energy to the first adjustment drive is switched from the source to an energy storage device and the safety control system monitors a position and/or movement of the first rotor blade. The first rotor blade is adjusted by the first adjustment drive in a direction of a predetermined stopping position, while the safety control system, as a function of the monitored position and/or movement, enables or effects a deactivation of a first power supply shut-off device.

Abstract: Disclosed are a system, apparatus and techniques for evaluating a dataset to confirm that the data in the dataset satisfies a data quality metric. A machine learning engine or the like may evaluate text strings within the dataset may be of arbitrary length and encoded according to an encoding standard. Data vectors of a preset length may be generated from the evaluated text strings using various techniques. Each data vector may be representative of the content of the text string and a category may be assigned to the respective data vector. The category assigned to each data vectors may be evaluated with respect to other data vectors in the dataset to determine compliance with a quality metric. In the case that a number of data vectors fail to meet a predetermined quality metric, an alert may be generated to mitigate any system errors that may result from unsatisfactory data quality.

Abstract: Design parameters for PDC drill bit including in-cone depth of cut controllers (DOCCs) are correlated to instances of coupled vibrations in the axial, lateral, and torsional directions occurring during downhole drilling. Design parameters are quantified by drilling efficiency (DE), average in-cone DOCC contact area, average weight on bit (WOB) taken off by in-cone DOCC, and average torque on bit (TOB) taken off by in-cone DOCC. Design guidelines to mitigate coupled vibrations are generated by correlating design parameter quantifiers and instances of coupled vibrations. Potential drill bit designs are then validated against the generated guidelines in order to mitigate vibration in future drilling runs.
