The inability to precisely contain and control  wellhead pressures during critical onshore  and offshore operations can have profound  HSE and economic ramifications. With our  

all-inclusive suite of customized manifolds,  M-I SWACO can design application-specific  configurations of chokes, gate valves,  fittings and technical specifications to give  

you precise pressure and flow control in  any operation requiring a choke to control  surface casing pressure.
