Abstract: A device for fixing a valve (1) to a tubular member (2) being situated in wellbore formed in a subterranean reservoir and is having at least one drainage section (11) including a plurality of such valves as to allow the flow of fluid into and out from the tubular member, respectively. According to the present invention the valve (2) is secured to the tubular member (1) by means of a sleeve portion (3), the sleeve portion being part of the valve or is formed like a separate sleeve (4) into which the valve is to be arranged.

Abstract: A system for recompletion of an old well (24) in order to achieve an increased oil recovery from a reservoir (26), said system comprising a pipe (27) inserted into the old well (24), at least two constrictors or swell packers (29) being arranged along the length of the recompleted well (24, 27) and defining a well section between two successive constrictors or swell packers (29), said system further comprising at least one autonomous valve (2) arranged in said well section defined between said two successive swell packers or constrictors (29). Disclosed is also a method for recompletion of an old well (24) in order to achieve an increased oil recovery from a reservoir (26).

Abstract: The present invention relates to a method of improving flow stability for a multiphase fluid flowing through a tubular element (1), comprising arranging a flow control device (2) along a flow path (F) through the tubular element (1), the flow control device (2) comprising a housing (4), an inlet (10) arranged on an upstream side of the control device (2), an outlet (23, 13) arranged on a downstream side of the control device (2), and a movable body (9) provided within the housing (4) along an internal flow path (11) through the control device (2) from the inlet (10) to the outlet (23, 13), the body (9) being arranged such that changes in velocity and/or properties and/or composition of the fluid flowing along the internal flow path (11) result in changes to the forces acting on the body (9) as a result of the Bernoulli principle, thereby adjusting the flow of fluid through the control device (2).

Abstract: A system for controlling the flow of fluid in a branched well from a reservoir (29), the system comprising a completed main well (27) having at least one uncompleted branch well (25), an annulus (24) defined between the reservoir (29) and a production pipe (1) of the completed main well (27) and at least two successive swell packers or constrictors (26) defining at least one longitudinal section of the main well (27) and within which at least one branch well (25) is arranged, and comprising at least one autonomous valve (2) arranged in said longitudinal section of the main well (27) defined between said two successive swell packers or constrictors (26). The uncompleted branch wells (25) are provided to increase the drainage area, i.e. maximum reservoir contact (MRC). Disclosed is also a method for controlling the flow of fluid in a branched well from a reservoir (29).

Abstract: A method for injecting a fluid into an oil and or gas reservoir or formation, in which the fluid flows into the reservoir or formation through a plurality of autonomous valves or flow control devices (2) provided along an injector (24), the valves (2) having a substantially constant flow-through volume above a given differential pressure for autonomously adjusting the flow of the fluid in order to ensure a substantially constant volume rate from the injector (24) to the reservoir or formation along an injector length.
