APMGS1200 Drilling Fluids System Poorboy Degasser

APMGS1200 mud gas separator or Mud Gas Separator, 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 . Alternatively, as long as it’s a safe distance from the rig, it could even be vented.

With mud’s separators, there are two main types. Also known as a ‘poor-boy’ and a ‘gas buster’, the more common of the two is called an atmospheric mud/gas separator. However, some mud/gas separators are designed to operate at moderate backpressure. Although these will mostly operate under 100 psig, it’s possible to come across those that work at the atmospheric gas vent line pressure plus the vent line friction drop.

APMGS1200 means the poor boy degasser is holding vessel diameter 1200mm. It is a popular model than other degassers. The treating capacity is up to 360m³/h. The degassing efficiency is up to 95%.

Why do we need the mud gas separator?

For oil and gas well drilling, we usually set mud gas separator ahead of shale shakers. The drilling mud out of wellbore will flow into degasser via the chock manifold. After degassed, fluid will flow out of degasser into a shaker by pass or possum belly. Degasser will help get rid of large quantity invading gas. These is harmful and toxic gas may lead blow out

Especially when we drill the gas well at the gas field. The degassing is very important to safety working. We use the poor boy degasser and vacuum degasser together to control the gas volume entrained in drilling fluids and remove them efficiently.

What is the main configuration of such degasser?

Vessel diameter of mud gas separator is 1200mm, the inlet and discharge line is 5'', 10''. While the gas vent line is 8''. The overall dimension of the whole degasser is about 2200x2200x6634mm. The vessel material is made of high-quality carbon steel, or the special carbon steel Q345R to resist the H2S. Another specification is the vent line length.

Some clients request we deliver the vent line together with the degasser. Some request 60m, while some request 100m. The vent line is the connection between the degasser and the flare ignition device.

Mud gas separator is made of steel sheet thicks 10mm for normal pressure working conditions. Some of the degassers are made of steel sheets thick 14-20mm per different working pressure requirements. The pipelines and the valves will be different from normal pressure degasser, too.

Is there another type or model poor boy degasser?

Yes. There are APMGS1000, APMGS800. The difference is the diameter of the line's diameter and the vessel thickness. Based on working conditions, there are normal pressure degasser and middle pressure, high-pressure degasser. And the working pressure can be 0.1Mpa to 6.4Mpa, or even higher according to practical condition.

Besides the normal standard poor boy degasser, there are some degassers that can be customized. For example, we have made the APMGS500, APMGS600 degassers for clients request smaller degasser and smaller flow rate. Please feel free to let us know the requirement of your degasser.

There is a customizable configuration of the mud leg. That means the U tuber or mud seal length for a degasser. The mud seal will help to prevent gas flowing out of the degasser during operation. For the degasser leg and base, we can configure it as the adjustable one. That means the laydown leg and the supporting base can be configured flexibly.
