摘要： A plunger lift system has a bumper and a landing positioned in tubing below a safety valve of a well. A plunger moving between the bumper and landing lifts columns of liquid above the plunger when pushed by downhole pressure. A valve on the plunger's housing is movable between open and closed positions to either permit or prevent flow through the plunger. When the plunger engages the landing, a striker rod on the landing opens the valve permitting fluid communication through the plunger to a sales line at the surface. The valve is biased to the closed position to prevent fluid communication through the plunger. When the plunger is disengaged from the striker rod, the valve closes so that application of downhole pressure can again move the plunger uphole. A controller cycles the plunger between the bumper and the landing by controlling fluid flow in the well.

摘要： Embodiments of the present invention provide methods and apparatus for reducing kinetic energy of a plunger within a plunger lift system. In one aspect, a lubricator is provided at a surface of a wellbore, the lubricator having a sealed, pressurized chamber therein to cushion the plunger upon impact. In another aspect, a method is provided for reducing the kinetic energy of the plunger by providing a compressed gas chamber within a lubricator, moving a kinetic energy-reducing surface which is partially bounding the chamber, and compressing the gas within the chamber to reduce kinetic energy of the plunger and cushion the impact force of the plunger.

摘要： Embodiments of the present invention generally relates to methods and apparatus for operating an artificial lift well. In one embodiment, the well is operated between an on cycle and an off cycle. Preferably, the off cycle is determined by detecting an increase in the pressure differential between the casing pressure and the tubing pressure. In another embodiment, the well is optimized by measuring the production of the well in one cycle of operation. The measured production is compared to the production of a previous cycle. A controller then optimizes the well based on the increase or decrease of the production from the previous cycle.

摘要： A method and apparatus for forming footwear, such as a sandal, with a footstrap secured to a sole by way of engagement of an insertion portion with a recess. The recess may be molded into a portion of the sole with an exposed opening at the outer surface of the sole leading to the recess formed in the sole interior. The exposed opening may be smaller in area than an area of the recess within the sole, and may be smaller that a largest cross-sectional area of the insertion portion. Thus, the insertion portion may be forced through the exposed opening, e.g., by deforming the insertion portion and/or the sole portion at the exposed opening, and received within the recess. The sole and/or insertion portion may be formed of a molded foam, e.g., that is resilient and water resistant.
