Method for treatment of wells

The invention relates to a valve suitable for use in high-pressure environment for transmitting a treatment fluid from exterior of which is affected by a pre-charged compression gas which keeps the bellows in contracted position and a piston preventing fluid communication between the tubing and the casing through the valve body. The interior of the bellows is affected by the tubing pressure, one half of which is transmitted to the bellows through radial sensing ports, and the other half of which is transmitted to the bellows through the bottom of the piston. When the pressure inside the bellows exceeds the pre-charged pressure, the bellows expands, pulling the piston upwardly and opening fluid communication from the tubing into the casing through the valve. A controlled-size fluid outlet port allows the tubing fluid to exit into the casing.

Method and apparatus for periodically introducing a separating fluid into a fluid stream

Underground liquid storage system and method

ABSTRACT This invention relates to a storage system and method for storing a valuable liquid in a subterranean cavity with a displacing liquid such as brine. The valuable liquid, which normally has a density above or the same as that of the displacing liquid, is modified by dissolving therein small amounts of a light fluid such as alkanes and alkenes of up to 4 carbon atoms, hydrogen, nitrogen, carbon monoxide or combinations thereof. The amount of the light fluid dissolved in the stored liquid is sufficient to maintain the density of this phase below that of the displacing liquid so that the valuable liquid is stored over the displacing liquid. Virtually any valuable liquid desired to be stored in a subterranean cavity, which is substantially immiscible with the displacing liquid, can be so stored with the system and method of the present invention, but there will generally be no advantage in doing so unless the density of the liquid to be stored is normally greater than or the same as that of the displacing liquid at contemplated storage condition. When saturated brine is used as the displacing liquid this invention is particularly attractive for storing relatively heavy liquids such as carbon disulfide and the halogenated hydrocarbons. The density of the liquid to be stored is preferably at least 1 kg/m3 lower than that of the displacing liquid to ensure that there is a sufficient density difference to avoid phase inversion or dispersion.

Passive propellant management system

Abstract PASSIVE PROPELLANT MANAGEMENT SYSTEM A passive propellant management system for a spacecraft liquid propellant tank (1) comprises several preferably V-shaped channels (2) which communicate liquid propellant from regions within the tank (1) to an outlet port (8), which expels liquid propellant but not pressurant gas. A liquid/bubble chamber assembly (9) couples the channels (2) with the outlet port (8). The channels (2) comprise relatively open portions (11) and relatively closed portions (10). In the relatively open portions (11), liquid is retained in a gap (12) between open ends of the V channels (2) and the inner wall of the tank (1). In the relatively closed portions (10), a screen, mesh or perforated plate (14) covers the open end of the V channels (2), intermediate the V channels (2) and the inner wall of the tank (l). The placement of the relatively open and closed portions (11, 10, respectively) is intentionally preselected based upon mission requirements. Where pressurant gas ullage is expected to be present, e.g., during-periods of high-g, relatively open portions (11) are used. Where liquid propellant is expected to be present, e.g., during periods of relatively low g, relatively closed portions (10) are used. The liquid/bubble chamber assembly (9) comprises a liquid trap (27) and bubble trap (28), which operate synergistically with each other and with the channels (2) to provide optimum liquid flow during all phases of the spacecraft mission.

Nitrogen enriched air supply system and aircraft

To provide a nitrogen enriched air (NEA) supply system which easily maintains low the concentration of oxygen within a tank before fueling. In the present invention, a subsidiary pipe 20 b that directly supplies NEA to a spill-back pipe 23 is provided. In a descent phase of an aircraft, the NEA is supplied to a second fuel tank 17 from the subsidiary pipe 20 b .

Thus, the concentration of oxygen within the first fuel tank 15 can be also maintained low. Accordingly, it is possible to cut out the need for supplying the NEA before fueling, and thereby fuel the fuel tank while avoiding fuel explosion.

A method comprising the steps of loading natural gas to transport it to a shipping container, mixing the natural gas with a liquid solvent to form a mixture of natural gas and solvent in liquid phase, dehydrating the natural gas, storing the natural gas mixture and solvent in liquid phase for transport in a looped pipe system at temperatures in a range of -40 ° C ...

Liquid filling system

A coupling has a housing which defines a vacuum chamber and, at least in part, a nozzle chamber. The nozzle chamber forms a valve chamber, an intake chamber, and an outlet chamber. A main valve is in the valve chamber. The main valve is movable between an open and closed position. A poppet valve is in the outlet chamber. An air outlet opens from the vacuum chamber into the nozzle chamber. An opening of an air uptake conduit opens into the vacuum chamber. The air outlet opening is distinct from the opening of the uptake conduit. When the main valve is in the open position the valve chamber is open to the outlet chamber and the outlet chamber is open to the intake chamber. In the closed position, the valve chamber is sealed off from the outlet chamber and the intake chamber is sealed off from the outlet chamber.

Control mechanism

Slug Mitigation

A method and apparatus for mitigating slug formation in a multiphase fluid stream that is flowing through a conduit wherein the conduit comprises a first portion and a second portion which is upwardly inclined to the first portion and wherein the multiphase fluid stream comprises a gaseous phase and a liquid phase, the method comprising the steps of: (a) determining the pres- sure in the conduit upstream of a slugging zone; (b) determining the pres- sure in the conduit downstream of the slugging zone; (c) determining the ac tual pressure difference across the slugging zone by subtracting the down stream pressure from step (b) from the upstream pressure from step (a); (d) determining the error between a target pressure difference and the actual pressure difference; (e) producing a signal comprising a first component which is proportional to the error and a second component which is propor tional to the rate of change of the error over time; and (f) using the signal produced in step (e) to control the position of an adjustable choke valve b cated downstream of the slugging zone so as to stabilise variations arising in the actual pressure difference over time.

Solenoid system for use in a downhole tool

A solenoid system for use in a downhole comprises a housing. A core is disposed within the housing. A plunger is moveably mounted within the housing. Windings are wrapped around at least a portion of the core and at least a portion of the plunger. A plunger ring is carried on the plunger.

An apparatus and method for detecting and handling liquid separation in liquid emulsions

An apparatus and method for detecting and handling liquid separation in a liquid emulsion disposed in a tank (1) by preventing separated liquid from entering a withdrawal conduit (3) disposed in the lowe r portion of the tank (1) by an apparatus comprising a pump (9) driven by an electric motor (15) and taking its suction from the lower portion of the tank (1) and discharging adjacent the central portion of the tank (1), a float (5), which sinks in the emulsion and floats on the high density liquid is cooperatively associated with a relay (17) to start the pump motor (15) when accumulated high density liquid raises the float (5) a predetermined amount, a time delay (21) runs the pump (9) a predetermined length of time sufficient to reemulsify t~ e accumulated high density and preventing it from entering the withdrawal conduit (3).
