    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: 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 prefer-ably 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: Se describe un sistema para la recompletación de un pozo viejo (24) con el fin de lograr una recuperación incrementada de petróleo desde un depósito (26), el sistema comprende un tubo (27) insertado dentro del pozo viejo (24), al menos dos constrictores u obturadores de esponjamiento (29) que están acomodados a lo largo de la longitud del pozo recompletado (24, 27) y que definen una sección de pozo entre dos constrictores u obturadores de esponjamiento sucesivos (29), el sistema comprende además al menos una válvula autónoma (2) acomodada en la sección de pozo definida entre los dos obturadores de esponjamiento o constrictores sucesivos (29). Se describe también un método para la recompletación de un pozo viejo (24) con el fin de lograr una recuperación incrementada de petróleo desde un depósito (26).

    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.
