Abstract: The present invention is directed to both a method for ensuring optimal conditions for separation, and a separator device for extraction of water, oil and gas from a mixture of water-oil-gas flowing in a straight pipe or straight channel. A separator comprises a certain length of pipe with diameter larger than or equal an inlet pipe and several inclined and profiled holes along the separator pipe wall. Holes in the pipe wall at the bottom of the pipe are provided for extraction of water, and one or more groups of inclined holes in the pipe wall at the top of the pipe are provided for extraction of oil and possible gas. Water and oil/gas are separated such that dispersed flow in the inlet is reduced to velocity equal or less than that of the separated flow at the outlet of the separator.

Abstract: A technique facilitates monitoring of a multiphase fluid flow. The fluid flow is directed through a choke valve comprising a choke actuation system which controls a flow rate of the fluid passing through the choke valve. The choke valve also comprises a velocity reduction area which is created by a choke gallery. The choke gallery reduces the velocity of the fluid flow to encourage separation of phases of the multiphase fluid. A sensor is positioned along the gallery at a desired region to monitor a property of at least one separated phase of the multiphase fluid. For example, the sensor may be positioned proximate a bottom of the choke gallery to monitor a property related to a water phase which separates and transitions to the bottom due to its greater density.

Abstract: A method and stabilizing gas lift controller for controlling the production flow rate of an oil well, which well comprises at least one gas injection choke (3) and/or at least one production choke (2), the choke or chokes being controlled as a function of process measurements, characterized in that pressure, temperature and flow rates are stabilized through active feedback control and continuous manipulation of said choke or chokes as a dynamic function of available process measurements.
