M-I SWACO advanced degassers are designed to remove virtually all entrained
gases—including hydrogen sulfide and corrosive oxygen—from drilling fluids. These degassers reduce the threat of dangerous and costly blowouts caused by recirculating gas-cut mud.
CD-1400 D-GASSER centrifugal-force degassing unit
The CD-1400 D-GASSER unit is a space-saving solution for removing dangerous entrained gases from drilling fluids. The centrifugal force operating principle of the CD-1400 D-GASSER unit—as opposed to a conventional vacuum or impact system—acts on the mud and multiplies the force acting on the gas bubbles to increase buoyancy and release, accelerating the bubble-rise velocity. As the bubbles rise toward the surface, they escape the mud and are further broken down by flow turbulence. The gas is discharged at a specified safe distance from the drilling operation while the restored mud is returned to the drilling fluid system.

CD-1800 D-GASSER low-profile, high-flow centrifugal-force degassing unit
The CD-1800 D-GASSER unit removes entrained gases—including H2S and corrosive oxygen—from drilling fluids in the return flow using a high-speed centrifugal-force system that is more powerful than conventional vacuum or impact systems. The self-contained unit is rig-footprint friendly and eliminates the need for disassembly and reassembly during rig moves. By generating up to 1,800 gpm, the CD-1800 D-GASSER unit provides the lowest horsepower-to-gpm throughput ratio. This high-flow-rate potential helps meet many deepwater offshore rig requirements for high-volume drilling.
