Abstract:
Electric motors configured for deployment in a downhole well environment are provided. Downhole well pumping systems including an electric motor are also provided. In one example, an electric motor includes a series of at least three magnets, one of the inner and outer two magnets being movable. A supply of alternating current is configured to alternate the polarity of one of the inner and outer two magnets to thereby cause one of the inner and outer two magnets that is movable to reciprocate and provide linear output to drive an operable production device. In another example, two adjacent, stationary magnets and at least one movable magnet are adjacent to one another. A supply of alternating current is coupled to the magnets so as to alternate the polarity of one of the movable and stationary magnets and to thereby to cause reciprocating linear output to drive the operable production device.
Abstract:
A touch sensitive capacitive keypad (200) is provided that multiple electrodes (201-210) and associated wire connectors (220-229) formed under a touch panel in a single layer of conductive material, where the electrodes (201-210) are arrayed in relation to a keypad to form unique combinations of two electrodes per key, where each electrode is shared with only immediately adjacent keys. The electrodes are sized and arranged so that a first electrode (e.g., electrode E4 205) associated with a given key (e.g., the “5” key) is sized and arranged so that it is shared by only surrounding keys (e.g., the “4,” “7,” and “8” keys), while a second electrode (e.g., electrode E3 204) associated with the given key (e.g., the “5” key) is sized and arranged so that it is shared by only surrounding keys (e.g., the “2,” “3” and “6” keys). As a result, the area for each capacitive electrode is at least twice the area of a given key.

Abstract:
A technique is provided for processing well fluid downhole. The technique utilizes equipment for separating a well fluid downhole into a water component and an oil component. The separation of water and oil can be controlled by selecting an appropriately sized flow restrictor for use in limiting the flow of one or both of the water and the oil. Additionally, a sensor system is used to monitor a well characteristic that enables adjustment of the downhole fluid processing based on well characteristic data from the sensor system.
