Degassing Units (Mud Degassers) – Sales High-Performance Vacuum Degassing Units for Drilling Fluid (Mud) Gas Removal and Well Control Operations Driscoil Equipment Limited supplies premium Vacuum Degassing Units (VDUs) for sale, engineered to efficiently remove entrained and dissolved gases from drilling fluids (drilling mud) during onshore, offshore, geothermal, HDD (Horizontal Directional Drilling), and mining operations. Vacuum degassers are an essential component of the drilling fluid solids control system, helping restore mud density, improve drilling efficiency, and reduce the risk of gas kicks and blowouts. Installed immediately downstream of the shale shaker and mud/gas separator, the vacuum degasser uses negative pressure to separate gas from drilling fluids before the mud proceeds to desanders, desilters, and decanter centrifuges. This process significantly enhances drilling fluid performance and contributes to safe and stable well control. Applications Our Vacuum Degassing Units are suitable for: Onshore Oil & Gas Drilling Offshore Drilling Rigs Jack-Up Rigs Semi-Submersible Rigs Drillships Geothermal Drilling Horizontal Directional Drilling (HDD) Mining Operations Water Well Drilling Coal Bed Methane (CBM) Drilling Shale Gas Development Exploration and Production Wells Operating Principle A vacuum degassing unit creates a controlled vacuum inside a sealed vessel, causing dissolved and entrained gases within the drilling mud to expand and separate from the fluid. The gas is safely vented while the degassed drilling fluid is discharged back into the mud system for continued circulation. This process restores drilling mud density, stabilizes viscosity, improves hydrostatic pressure, and enhances overall well control performance. Vacuum degassers are capable of removing more than 95% of entrained gas from drilling fluids under typical operating conditions.
