[pdf] If the hydrostatic head of the drilling fluid is insufficient to control subsurface pressure, formation fluids will flow into the well. To maintain well control, back pressure is applied by routing the returns through adjustable chokes until the well flow condition is corrected. The chokes are connected to the blowout preventer. .
A choke manifold is an assembly of valves, through which the return flow from the well is routed when the blowout preventers are closed, with the purpose of applying calculated backpressure. Choke manifolds may be assembled in a variety of layouts but they. .
Of the two choke line valves on or adjacent to the stack, the inner manual valve is kept open, and the second (the remotely controlled. .
Recommended practices for planning and installation of choke manifolds for surface installations include: 1. Manifold equipment subject to well and/or.
