    摘要： Methods and systems for detecting downhole bit dysfunction in a drill bit penetrating a subterranean formation comprising receiving a plurality of drilling parameters characterizing a wellbore drilling operation and calculating bit aggressiveness (μ) at each of a plurality of points during drilling, wherein each point corresponds to time, depth, or both. A depth-of-cut (DOC), time derivative of bit aggressiveness ({dot over (μ)}), calculated as dμ/dt, or both, is calculated at each of the plurality of points. A two-dimensional data representation of the plurality of points, comprising μ in one dimension and DOC, {dot over (μ)}, or both, in another dimension is created. Data features are extracted from the two-dimensional data representation and downhole bit dysfunction is identified by comparing the extracted data features with predefined criteria.

    摘要： The present invention discloses apparatuses, systems, and methods for operating a gas well. Some embodiments include a plunger apparatus configured to fall through a continuous water phase (including water slugs) in a gas producing well by overcoming pressure and drag 5 forces from the water by having a sufficient mass, hydrodynamic profile, and sufficiently large area for passage of the continuous water. In one embodiment, a plunger body and plug mechanism are provided, wherein the plug mechanism has open and closed positions, which may be automatically changed or controlled by a surface or other control system, and wherein the plunger body and plug may be a physically integrated one-piece system, or an interoperable two piece system.

    摘要： A data telemetry system for multi-conductor wirelines to enhance transmission of analog and digital signals with frequency content up to 100 kHz by assigning at least two conductors to a first terminal of a data transmittal means and to a first terminal of a data receiver means and connecting at least one additional conductor to a second terminal of a data transmittal means and to a second terminal of a data receiver means. Pairing conductors reduces attenuation and crosstalk and permits the signal to contain multiple frequency modulated carrier bands with individual channel bandwidths of up to 3 kHz or higher.
