Low-pressure autochoke console
Engineered for low-surface-pressure MPD and underbalanced drilling up to 1,500 psi.
The AUTOCHOKE pressure-balanced drilling choke regulates pressure automatically under a diverse range of conditions. It reduces risk of formation breakdown or secondary bubbles during well control and drilling operations, delivering faster, safer kick control and implementation of MPD practices. By maintaining casing pressure, the drilling choke makes stripping pipe simpler and safer.
As drillpipe is lowered into the hole, an equal volume of fluid is automatically displaced through the choke. A patented sliding shuttle and sleeve design automatically adjusts fluid flow to regulate casing pressure.
The tungsten carbide- or Stellite-coated internal wear parts are all replaceable and more durable than needle-valve or rotating-disc chokes.
The drilling choke provides easy, predictable casing pressure control. It enables precision control for
The choke reduces lost circulation, gas intrusion, fluid costs, production damage, and blowouts.
The self-cleaning orifice reduces plugging. The unit contains easy-to-maintain internal components. A simple eight-bolt design enables 5-min internal inspection.
The M-I SWACO AUTOCHOKE unit provides automatic, precise pressure control.
Near-constant bottomhole pressure held.
The only true pressure-balanced choke provides easier, more precise pressure control.
