摘要 |
A technique is provided to facilitate fluid flow and pressure control in a well with an interventionless flow valve system. The valve system is coupled to a well component string deployed downhole in a wellbore. The valve system controls flow and pressure between an interior and exterior of the string and comprises a valve controlled by an activation device. The activation device is responsive to a unique pressure and time signal transmitted downhole. |
