Five tips on maintenance of poor boy degasser

Five tips on maintenance of poor boy degasser:

1. Open the screw plug for sand discharge in the manifold side to remove sand when the mud discharge manifold is blocked.

2. The separator assembly is pressure container,so it must be used in designed working pressure and surrounding. Overpressure work is forbidden. The safety valve should be checked at least once a year.

3. The baffle should be checked after a well has been completed. Replace it if there is something wrong.

4. Welding on the separator assembly is forbidden.

5. The exhaust pipe and liquid discharge pipe should be arranged separately when the separator is paralleled. Uniting the pipe is forbidden .


Mud gas separator is commonly called a gas-buster, poor boy degasser and liquid gas separator. 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.
