    Abstract: A method for flow control and a self-adjusting valve or flow control device, in particular useful in a production pipe for producing oil and/or gas from a well in an oil and/or gas reservoir, which production pipe includes a lower drainage pipe preferably being divided into at least two sections each including one or more inflow control devices which communicates the geological production formation with the flow space of the drainage pipe. The fluid flows through an inlet (10′) and further through a flow path of the control device (2) passing by a non-disc shaped movable body (9′) which is designed to move relative to the opening of the inlet and thereby reduce or increase the flow-through area (A2) by exploiting the Bernoulli effect and stagnation pressure created over the body (9′), whereby the control device, depending on the composition of the fluid and its properties, automatically adjusts the flow of the fluid based on a pre-estimated flow design.

    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).

The fluid flows through an inlet (10') and further through a flow path of the control device (2) passing by a non-disc shaped movable body (9') which is designed to move relative to the opening of the inlet and thereby reduce or increase the flow-through area (A2) by exploiting the Bernoulli effect and stagnation pressure created over the body (9'), whereby the control device, depending on the composition of the fluid and its properties, automatically adjusts the flow of the fluid based on a pre-estimated flow design.

    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 tubular member having at least one drainage section (1) including a first plurality of self-adjustable valves or flow control devices (2) to control the flow of fluid into the drainage section from a well formed in a subterranean reservoir, each of the valves (2) comprising an inlet or aperture (10), thereby forming a flow path (11) through the control device (2) passing by a movable disc or body (9) designed to move freely relative to the opening of the inlet and thereby reduce or increase the flow-through area (A2) by exploiting the Bernoulli effect and any stagnation pressure created over the disc (9), whereby the valve (2), depending on the composition of the fluid and its properties, autonomously adjusts the flow of the fluid based on a pre-estimated flow design. To allow injection of fluid into the subterranean reservoir, the drainage section (1) is provided with a second plurality of such self-adjustable valves (32), each being situated in a direction opposite of the first plurality.
