DC Machinery developed the horizontal drill mud gas separator but also supplies any custom units according to customer specifications and preferences. We also provide complete system gas handling analysis to establish the capacity of the separators in conjunction with the vent line and mud seal.


There are three types of mud gas separator used in the oil well drilling. Closed bottom, open bottom and float type. however the closed bottom is most popular one. It is closed at vessel bottom with mud return line directed back to the mud tank. Mud leg is maintained in the separator by installation of an inverted U-shaped bend in mud return line.


There are three major types of mud gas separators that Tech-Fab fabricates:

Open bottom: These separators are often called “poor boys,” and immerse the bottom of the machine in the mud deposit.
Closed bottom: A closed bottom mud gas separator features a sealed base, which directs the mud return into the storage tank.
Float: The float design is similar to the closed bottom type of separator, except that it has a valve rather than a permanently sealed line for the mud return. Fixed or elevated pedestals are also used to mount the base.

DC Machinery offers a range of mud gas separators and degassers for clients engaged in drilling and extraction activities. To learn more, or to request a price quote, please contact us
