    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 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: The present disclosure provides a method for separating and purifying a landfill gas stream. In one embodiment, the method includes a step of collecting a crude landfill gas stream which includes at least methane, carbon dioxide, oxygen, and nitrogen gases. The method also includes a step of separating the crude landfill gas stream into at least an intermediate landfill gas stream and a first waste gas stream using a membrane separation unit, wherein the intermediate landfill gas stream is enriched in methane and depleted in carbon dioxide relative to the crude landfill gas stream. The method further includes a step of separating the intermediate landfill gas stream into at least a final landfill gas stream and a second waste gas stream using a pressure swing adsorption separation unit, wherein the final landfill gas stream is enriched in methane and depleted in carbon dioxide, oxygen, and nitrogen relative to the intermediate landfill gas stream. The first and second waste gas streams are collected to form a fuel composition and the fuel composition is delivered to a generator unit so that the fuel composition may be used to produce electricity.

    摘要: A threaded connection with improved fatigue-life useful for connecting adjacent sections of a pipe string subject to bending, tensile, and compressive stresses such as a drill collar string is disclosed. The connection comprises a pin member which is threadedly engageable with a corresponding box member. In the preferred embodiment, the inventive connection is designed to have bending strength ratio ("BSR") of about 3.20 or greater, and more preferably, in a range between about 3.20 and about 4.00. The preferred thread form of the connection is a V-type thread form having two flank angles of 30 degrees and a 0.038 inch root radius. Other design features may be used in combination with the threaded connection to further improve the connection's fatigue-life. Such design features include a tapered pin bore, an increased root radius for selected box threads, an internal box stress relief groove, a box bore stress relief groove, an extended pin relief groove, and modification of the API boreback box design to provide an increased number of threads having full threaded engagement.

    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.
