Patent number: 9896906Abstract: A technique facilitates regulation of flow through a flow control device to improve a well operation, such as a production operation. The technique utilizes a flow control device which has a valve positioned in a housing for movement between flow positions. The different flow positions allow different levels of flow through a primary flow port. At least one flow regulation element, e.g. a Venturi based flow regulation element, is used in a control line in communication with the valve to establish a differential pressure acting on the valve. The differential pressure is a function of fluid properties and is used to autonomously actuate the flow control device to an improved flow position.Type: GrantFiled: August 28, 2015Date of Patent: February 20, 2018Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Andrzej Tunkiel, Terje Moen, Aleksandar Rudic, Gocha Chochua
