TUBULAR VALVING SYSTEM AND METHOD
First Claim
Patent Images
1. A tubular valving system, comprising:
- a tubular having a bore therethrough with at least one port defining fluidic communication between the bore and an outside of the tubular; and
a valve stem disposed within the bore of the tubular being longitudinally movable with respect to the tubular, the valve stem having an outer surface slidably engagable with the bore, the outer surface having features that provide variably choked fluidic communication between the bore and the at least one port, and an amount of choke varies depending upon a relative position of the valve stem with respect to the bore.

17. A method of choking a tubular valve, comprising:
-
slidably engaging a valve stem within a bore of a tubular between an open end of the tubular and at least one port fluidically connecting the bore to an outside of the tubular; and varying at least one of a flow path area or a flow path length between the bore and the at least one port by moving the valve stem relative to the tubular. - View Dependent Claims (18, 19, 20)
