High-Volume Mud Gas Separator Provides Effective Surface Control Of Drilling Fluid And Gas Circulation

General information of Mud Gas Separator

Mud Gas Seperator is also called Poor Boy Degasser , located downstream of the choke manifold, is a vertical vessel used to separate any gas from drilling fluid during well control situation. Once the gas has been separated, it can pass through the vent line in the derrick. Alternatively, as long as it’s a safe distance from the rig, it could even be vented.

What factors will limit this flow rate?


Mainly, this will come from the relationship between the hydrostatic head of fluid located at the mud outlet and the back pressure at the outlet to the vent line. At times, there’s a risk the back pressure at the gas flow will be greater than (or even equal to) the mud outlet’s available hydrostatic head. When this occurs, the shaker head tank may be in danger.
At all times, minimizing risk should be a key objective and this can be aided with a large ID and straight vent line. Elsewhere, the mud outlet should be set up with a hydrostatic head of at least ten feet.

What Makes Poor Boy Degasser Price?


Degasser size with tank vessel 800mm, 1000mm or 1200mm size for different mud flow capacity and price is higher for larger size degasser.
Pressure request makes very different price, the higher pressure the higher price. All AIPU supplied degasser is non-pressure vessel for cost effective. But many site will require pressure vessel for degasser with a certain pressure figure and much higher price.
Extra request on degasser design like on degasser size, customized degasser skid, pipeline arrangement, etc.


AIPU is able to supply a degasser package with a set of poor boy degasser and a set of flare ignition device and a certain length of pipeline between to 2 equipment. The flare ignition device is used to burn waste gas 30 meters away from drilling site. More information, please click AIPU website.
