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: The invention relates to a method and apparatus for of controlling the flow of a fluid. The fluid comprises a liquid phase and a dissolved gas phase. The fluid passes through a valve, the valve comprising a fluid inlet and a movable body located in a flow path through the valve, the movable body being arranged to move freely relative to the opening of the inlet to vary the flow-through area through which the fluid flows by means of the Bernoulli effect. The dimensions of the valve are such that flow of the fluid past the movable body causes a drop in pressure to below the bubble point of the gas phase in the liquid phase, thereby increasing flow of the fluid through the valve.
