System and method for controlling flow in a well production system
First Claim
1. A flow control system for a horizontal well production system comprising a casing, a tube having an intake opening and disposed within the casing, and a gap formed between the casing and the tube, the flow control system comprising;
- a valve comprising an orifice, coupled to the tube and disposed proximate to the intake opening; and
an actuator coupled to the valve and configured to open the valve along a radial direction, in response to a presence of a liquid in the gap, proximate to the intake opening, to permit flow of the liquid into the tube via the intake opening, and to close the valve in response to a presence of a gas in the gap, proximate to the intake opening, to prevent flow of the gas into the tube via the intake opening, wherein the valve and the actuator are disposed within the tube, and wherein the tube is a production tube.

Abstract
A flow control system is provided for a horizontal well production system having a casing, a tube having an intake opening and disposed within the casing, and a gap formed between the casing and the tube. The flow control system includes a valve having an orifice, coupled to the tube and disposed proximate to the intake opening. The flow control system further includes an actuator coupled to the valve and configured to open the valve in response to a presence of a liquid in the gap, proximate to the intake opening, to permit flow of the liquid into the tube via the intake opening, and to close the valve in response to a presence of a gas in the gap, proximate to the intake opening, to prevent flow of the gas into the tube via the intake opening.

16. A method for controlling flow in a horizontal well production system, the method comprising:
-
directing a gas and a liquid via a gap formed between a casing, and a tube disposed within the casing; opening a valve comprising an orifice, coupled to the tube and disposed proximate to an intake opening formed in the tube, from an interior of the tube via an actuator, along a radial direction in response to the presence of the liquid in the gap, proximate to the intake opening, to permit flow of the liquid into the tube via the intake opening, wherein the valve and the actuator is disposed within the tube, and wherein the tube is a production tube; directing the flow of the liquid via the tube to a horizontal well surface, using a pump; closing the valve along the radial direction from the interior of the tube via the actuator in response to a presence of the gas in the gap, proximate to the intake opening, to prevent flow of the gas into the tube via the intake opening; and directing the flow of the gas via the gap to the horizontal well surface. - View Dependent Claims (17, 18, 19, 20, 21)
