  • Precise choke systems and methods
    Patent number: 10197077
    Abstract: An embodiment includes a choke system comprising: a choke body; a gate having first and second sidewalls opposing one another; a first seat including a first channel and first conduits; a second seat coupling the second sidewall to the choke body and including a second channel; a third seat coupling the first sidewall to the choke body; a plug coupled to a bottom surface of the gate; a choke stem coupled to a top surface of the gate; wherein (a) the choke system is to convey fluid through the first channel and first conduits when the gate is open and fluid is pressurized in the second channel, and (b) the first conduits of the first seat have first long axes that are non-collinear with a long axis of the first channel. Other embodiments are described herein.
