The field-proven M-I SWACO MUD/GASSEPARATOR* is an extremely reliable, vital piece of safety equipment for today’s drilling operations. It is ideal for use where drilling is likely to encounter large volumes of gas, sour gas or when an operator is drilling with an underbalanced mud column. The MUD/GAS SEPARATORis primarily used to sep -arate and safely vent large pockets of free gas, that may include toxic gases such as hydrogen sulfide, from the drilling-fluid system.
Separates free gas. Separates and vents large pockets of free-gas accu-mulations, including toxic gases such as H2S, from the active system.
Reduces hazardous gas threat. The separated gas is carried by vent lines to a remote location and flared. Fail-safe gas delivery is controlled by a back-pressure manifold valve in the flare line.
Skid-mounted and trailerable.
Simplifies transport, spotting and installation. Unit can lay down during over-the-road transport.
Versatile configuration. The MUD/GASSEPARATORis available in either a land or compact offshore configuration. The land version is designed so it can be raised or low-ered for flowline adjustments to minimize piping.
ASME and NACE specifications.
The only separator designed in accordance with ASME and NACE specifications.
Rugged construction. The unit is ruggedly built and coated with corrosion-resistant epoxy to ensure long life while processing hazardous and toxic gases.
Features and Benefits
• Separates large volumes of free gas including H2S
• Reduces threat of hazardous and toxic gases
• Skid-mounted for easy transport
• Versatile configurations
• Designed to ASME and NACE specifications
• Corrosion-resistant epoxy coated to ensure long life
How it works
The M-I SWACO MUD/GASSEPARATOR consists of a cylindrical pressure vessel in a fixed vertical position.
Inside is a series of specially angled baffle plates, stepped from the top to the bottom.
When contaminated mud is routed into the separator, it flows downward successively over each plate. During this process, the heads of entrained gases “break out.” The released gas is then carried by the vent lines to a remote location where it can be safely flared.
The flow of liquid from the ves-sel can be regulated by a liquid-level-control valve or a U-tube, ensuring adequate retention time in the separator for the gas to break out.
The gas delivery from the MUD/GASSEPARATORto the flare line can be controlled by a back-pressure manifold (valve) in the flare line.
The M-I SWACO MUD/GAS SEPARATORis ideal to assist in controlling dangerous, surface expansion and accumu -lation of gas during a well kick.

The M-I SWACO SUPERMUD/GAS SEPARATOR* offers the highest gas- and liquid-handling capacity available. Its highly efficient baf-fling system maximizes mud/gas sep aration, enabling operators to drill deeper, larger-diameter wells and exploratory wells at higher circu lating rates while safely han-dling greater volumes of gas. It also minimizes mist carryover and gas-cut mud at the flowline.
Features and Benefits
• Large 6- x 22.3-ft (1.8- x 6.8-m) diameter vessel with 12-in.
(304.8-mm) flare line. Allows the highest gas- and liquid-handling capacity available.
• Optimizes safety and control.
The SUPERMUD/GASSEPARATOR unit enhances safe drilling practices during underbalanced conditions, improves “kick”
handling capabilities, permits optimum cir culation rates and large-diameter holes to be drilled through the targeted zone, pro-vides more efficient separation of emulsions and gas-cut mud in either gas or oil environments, and eliminates the need and cost of a skimming system in a gas environment.
• High-efficiency baffle system.
Maximizes mud/gas separation, minimizes mist carryover which produces a cleaner flare and minimizes gas-cut mud at the flowline.
• Capable of pressured operation.
Increases gas- and liquid-handling capacities and permits immedi-ate sale of gas during drilling operations.
• Adjustable U-tube (liquid seal) height to 14 ft (4.3 m) without additional elevation of the vessel.
Increases vessel pressure, creat-ing higher flare capacity, enablcreat-ing more efficient separation of emulsions and gas-cut mud in either gas or oil environments.
• Higher liquid-capacity vessel with multiple nozzle ports.
Permits pumping of “hot” mud directly into the vessel to reduce gas hydrates. Increases mud gra-dient within U-tube to increase gas-handling capacity.
• Manufactured to exacting standards in accordance with:
– NACE MR-01-75 for H2S service.
Provides for safe handling of corrosive, deadly sour gas and gas-cut drilling fluids.
– OSHA 29CFR 1910 for safety.
Provides safe and easy access for rig-up and servicing via ladder and platform system.
– ASME boiler and pressure ves-sel code Section VIII, Division I, Section IX, lethal service and so stamped. Provides maximum rigsite safety during underbal-anced drilling operations.

How it works
• The mud enters the vessel through the intake line
• The fluid runs over the baffle system as gas is separated and migrates out of the vessel through the flare line
• The degassed mud is dis-charged into the active mud system through the mud return line
