Vertical Drilling Fluids System Gas Mud Separator & Poorboy Degasser

A mud gas separator also known as poor boy degasser is a special tool designed particularly for degassing gas-invaded mud effectively in the first grade. It is commonly used to remove big bubbles majorly. While these refer to the remaining gases in the fluids that are used to fill some parts of a good annulus.

However, these mud gas separators come up with their own features and benefits for the users. Let’s have a look at the overview below to know more.

Here are some of the most important features of a gas separator that are essential for you to know:

Ensured safe area of combustion

This gas separator can separate and discharge enormous free gas including poisonous gases from drilling fluids. Most importantly, the separated gas is properly carried by discharge lines to ensure a higher level of safe and secure area for combustion.

Ruggedly built unit

This mud separator unit is ruggedly built. Even more, it is coated with an effective and superior quality anti-corrosion epoxy. All of this is done just to ensure its reliability and durability to the highest possible level. Even more, the unit comes up with a longer service life when processing toxic and hazardous gases.

Competitively priced

This mud gas separator is a competitively priced unit that will never hit your money pocket hard. You can find various versions to see which one can fit into your budget with ease and can go ahead with that.

Do you want to know how a mud separator can benefit you? Let’s have a look at the key advantages of this mud separator given below to know more about the things in this regard:

The baffle plates that exist within the vessel of this mud gas separator have the potential to create maximum free gas removal in the best possible way.

The skid-mounted design of this mud gas separator can ensure easier transportation, rig up and rig down as well.

The unit is completely designed and manufactured as per ISO standards to ensure quality and reliability in the best possible way.

That’s all you need to know about the gas separator. Make sure to consider unit specifications before making any purchase.

Why do we need the mud gas separator?

For oil and gas well drilling, we usually set mud gas separators ahead of shale shakers. The drilling mud out of the wellbore will flow into the 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 are 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 a degasser?

The vessel diameter of the 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.

The mud gas separator is made of a steel sheet that 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.

The concept of this equipment is density difference between liquid and gas. When the mud coming out from the choke manifold goes into the mud gas separator, mud will hit the baffle plates which are used to increase travelling time and allow gas to move out of the mud. Gas which has lower density than air will move up and mud will goes down due to gravity. Mud leg will provide hydrostatic pressure in order to prevent mud going through the separator into the rig.

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 conditions. 

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 who request smaller degasser and smaller flow rates. 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 from 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.
