Abstract: Embodiments of an apparatus, a system, and a method are provided for deliquification of a production well. The apparatus can be a production tube that receives produced fluid from a subterranean reservoir and provides a pathway for transmission of the produced fluid to a surface location. The production tube includes a nozzle disposed therewithin and an opening positioned proximate to the nozzle through which a foaming agent is introduced into the production tube. The nozzle has a first end that defines an inlet, a second end distal to the first end that defines an outlet, and a passageway extending between the first end and the second end such that the produced fluid received by the inlet is delivered to the outlet. The passageway defines a region of decreased cross-sectional area that agitates the produced fluid passing through the nozzle thereby increasing mixing of the foaming agent.

Abstract: A self-stabilizing gas lift valve apparatus for oil and gas production. The apparatus includes a valve body having at least one gas inlet in communication with an elongated gas chamber in the valve body. An impingement disk is moveable in the elongated gas chamber. A conical plug extends from the impingement disk with the conical plug having a valve plug extending axially therefrom. A conical cup terminates in a valve seat wherein the conical cup receives the conical plug therein. A valve closure force mechanism urges the valve plug toward the valve seat. Gas injected through the gas inlet provides a force upon the impingement disk to overcome the force of the valve closure force mechanism in order to open the valve plug. When the gas injected exceeds a predetermined force, the impingent disk is moved and a conical space between the conical plug and the conical cup is reduced.

Abstract: An apparatus, system, and method are provided for deliquefying a produced fluid being produced from a gas well. The apparatus can be a nozzle configured to be disposed in a production tube extending from a subsurface gas reservoir to a surface location and configured to provide a pathway for transmission of the produced fluid from the reservoir to the surface location. The nozzle generally can define a first end for receiving the produced fluid from the reservoir, a second end distal to the first end, and an inner surface extending between the ends. The inner surface can define an inwardly tapered inlet portion at the first end, an outwardly tapered outlet portion proximate the second end, and a venturi neck portion between the inlet and outlet portions. The nozzle can be configured to reduce the pressure of the produced fluid and thereby deliquefy the produced fluid passing therethrough.

Abstract: The modular connection assembly comprises a connector (4) made of insulating material, a conductor connecting bridge (10) and a fixing and contact member (9); the connector (4) has side socket members (5) to relate to similar units (4) and it also includes passages (6)(7)(8) for cables (3), for bridges (10) and for fixing members (9); the bridge (10) includes modular sections (10a) and threaded holes (10b) for the fixing member (9); which are screws ending in contact ends (9a) able to perforate the sheath (3a) of the conductor cable (3) and contact it. The side socket member (5) allow the group of several connectors (4) integrated in a modular connection set. The conductor cables (3) are inserted into the first passage (6) of the connectors (4). The bridges (10), after cutting and separating the unnecessary modular sections (10a), are inserted into the second passage (7) of the connectors (4).
