    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.

    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: There is described thermal hydrocarbon recovery apparatus for thermal recovery of hydrocarbons from a geological formation and an associated method. In an embodiment, the apparatus may be provided with inflow control devices for autonomously adjusting a flow of fluid through the flow control device. The flow control devices are provided to tubing, which is located in a wellbore in use and provides fluid connection between the geological formation and an inside of the tubing. The tubing is arranged to perform at least one of: injecting steam into the geological formation for heating hydrocarbons; and moving steam heated hydrocarbons from the geological formation to the surface.

    Abstract: La presente invención se refiere a un elemento tubular que tiene al menos una sección de drenaje (1) que incluye una primera pluralidad de válvulas o dispositivos de control de flujo (2) autoajustables para controlar el flujo del fluido hacia la sección de drenaje desde un pozo formado en un depósito subterráneo, cada una de las válvulas (2) comprende una entrada o abertura (10), por lo cual se forma una ruta de flujo (11) a través del dispositivo de control (2) que pasa por un disco o cuerpo movible (9) diseñado para moverse libremente con relación a la abertura o entrada, y por esto reducir o incrementar el área de paso del flujo (A2) por la explotación del efecto de Bernoulli y cualquier presión de estancamiento creada sobre el disco (9), por lo cual la válvula (2), dependiendo de la composición de fluido y sus propiedades, ajusta autónomamente el flujo del fluido con base en un diseño de flujo pre-estimado. Para permitir la inyección del fluido en el depósito subterráneo, la sección de drenaje (I) está provista con una segunda pluralidad de tales válvulas autoajustables (32), cada una de las cuales está situada en una dirección opuesta a la primera pluralidad.

    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: 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).
