摘要： Natural gas produced from a well by executing a multiple-phase gas recovery cycle which includes a phase during which a relatively lower evacuation pressure is applied within the entire well bore to assist in accumulating liquids at a well bottom. The relatively lower evacuation pressure augments the national earth formation pressure to produce natural gas and liquid more rapidly. The phases of the gas recovery cycle are also coordinated with the phase in which the relatively lower evacuation pressure is applied throughout the well to facilitate a greater natural gas production rate.

摘要： A system for controlling fluid flow from multiple isolated producing zones in a well is provided. Components of the system are placeable in and retrievable from bottom entry side pocket mandrel sections permanently installed in a production tubing string in the well. These components include retrievable isolation valve modules. Control signals for modules are developed either downhole or at the surface and modules may be placed or retrieved through the production tubing without pulling the production tubing from the well. In high flow rate applications the sliding sleeve flow control valve of the present invention provides a variable aperture valve having a fully open cross sectional area equal to that of the production tubing, thereby achieving a minimal pressure drop across the valve.

摘要： A tool having a tube string made of inner and outer coaxial tubes, and a dewatering natural gas-assisted pump at the bottom of the tube string. The pump includes a nozzle, an eductor, and a diffuser. The nozzle has a central inlet and a number of primary angled gas outlets, each opening to a gas supply space between outer and inner pipes, and to the interior of the inner tube. These angled outlets allow the gas to accelerate, contributing to a venturi effect in the tool. A fluids/debris/etc. mixture moves from the nozzle ring to the inwardly inclined eductor, which causes the mixture to converge. Then, the mixture diverges along the outwardly inclined diffuser to the inner pipe in which the mixture moves to the surface. At the convergence/divergence area, the venturi effect is enhanced. That is, a number of secondary outlets, formed in the diffuser, introduces additional gas from the gas supply space to the interior of the inner tube.

摘要： In accordance with the present invention, a downhole separation tool is provided which utilizes a downhole separation chamber with a series of fluid regulators responsive to a formation fluid and constituent components for separate desirable formation yields from the less desirable yields prior to lifting the fluids to the surface. The separation chamber has an input for the formation fluid, a production output, and a disposal output, in a tree arrangement according to the density order of the fluids in the separation chamber. The input flow regulator is coupled to the separation chamber input, the production regulator is coupled to the production output, and the disposal regulator is coupled to the disposal output. Each of the regulators are responsive to a fluid density of the formation fluid, first constituent and remainder constituent, accordingly, to regulate the flow of the respective fluid. According to a method of the present invention of separating a production fluid downhole, a production fluid is flowed from a subterranean formation into a separation chamber. The production fluid is separated over a given residence time period into a series of constituent layers. The first constituent, such as oil, is lifted in a generally continuously manner when under sufficient pressure to the surface, and the remainder constituent, such as salt water, is disposed to a disposal layer in the subterranean formation.
