Poor boy degasser/ Mud gas separator in Solids control

Introduction of mud gas separator

Mud Gas Separator is commonly called a gas-buster or poor boy degasser. It captures and separates large volume of free gas within the drilling fluid. If there is a “KICK” situation, this vessel separates the mud and the gas by allowing it to flow over baffle plates.

The gas then is forced to flow through a line and vent it to a flare. A “KICK” situation happens when the annular hydrostatic pressure in a drilling well temporarily (and usually relatively suddenly) falls below that of the formation, or pore, pressure in a permeable section down hole and before control of the situation is lost. It is always safe to design the mud/gas separator that will handle the maximum possible gas flow that can occur.


The principle of mud/gas separation for different types of vessels is same. The types of closed bottom type, open bottom type and float type. According to pedestal or base type there are fixed type and elevating type. Poor boy degasser in China is usually named according to vessel diameter. So the type also incurs FLQ800 or ZYQ 800, FLQ1000, FLQ1200 and FLQ1400. Usually, the degasser?s type or configuration is customizable.

Principle of operation

The principle behind the mud gas separator is relatively simple. On the figure, the mud and gas mixture is fed at the inlet allowing it to impinge on a series of baffles designed to separate gas and mud. The free gas then is moved into the flare line to reduce the threat of toxic and hazardous gases and the mud then discharges to the shale shaker and to the tank.


Mud gas separator for drilling fluids solids control

Mud gas separators also called Poor boy degasser, Liquid-gas separators, Mud/Gas Separators, etc in other countries. OGEM Solids Control?designs and manufactures FLQ Mud gas Separators. Mud gas Separator 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 under balanced mud column. This Mud gas Separators is primarily used to separate and safely vent large pockets of free gas, which may include toxic gases such as hydrogen sulfide, etc. from the drilling fluids processing system.


FLQ series Mud gas separator

  • FLQ series Mud gas separator (Poor Boy Degasser) is a professional equipment to treat the gas invading mud. When the drilling mud result gas invades, the proportion of its weight and viscosity has a greater deviation not to meet the requirements of drilling.


  • The serious situation is that would cause Chung well, and even blowout accident occurred, if not to treat it timely FLQ series Mud gas Separator combined with the Electric Ignition Device can be used to ensure the drilling process smooth.


  • It is divided into the normal pressure Mud gas separator and pressure auto-control Mud gas separator, according to the pressure.


Mud gas Separator is your best choice to prevent drilling mud invasion. When you need, you can contact us freely, the best price and quality will be served.
