Gas buster also called poor boy degasser or mud gas separator, which is used for oil and gas drilling. The description on oilfield glossary is “A simple separator vessel used to remove free or entrained gas from fluids circulated in the wellbore, such as mud used during drilling operations. The gas buster typically comprises a vessel containing a series of baffles with a liquid exit on the bottom and a gas-vent line at the top of the vessel”.
Gas Buster
is an important equipment to prevent well kick during drilling, so the production process should be strictly controlled. The process control including the following aspects:
1 Surface preparation
Steelwork:
Before all paint actions will be taken the surface to be coated must be clean and free from contamination. Sharp edges shall be rounded or smoothed to radius 2 mm. Hard surface layers shall be removed by grinding before blasting. All welds shall be fully sealed.
Abrasive Blast Cleaning:
As abrasive steel grit or copper slag can be used. If oxidation has occurred between blasting and application of paint, the surface should be reblasted to the specified visual standard.
Surface defects revealed by the blast cleaning process, should be ground, filled, or treated in the appropriate manner.
2 Painting

As refer to mud gas separator or poor boy degasser, you may heard of “Flare stack”.
A flare stack (alternatively known as gas flare ) is a vertical vent pipe used in oil and gas drilling sites. The pipe diameter of flare stack is usually 8” for GN ZYQ series poor boy degasser.
 flare stack The function of flare stacks
They are used to eliminate waste gas invaded in the drilling mud, otherwise it will lead to “blowout”, “kick”. They also act as safety systems for non-waste gas and is released via pressure relief valve when needed to ease the strain on equipment. They protect gas processing equipments from being over pressured. Also in case of an emergency situation, the flare system helps burn out the total reserve gas.
Whenever the poor boy degasser are over-pressured, the pressure relief valves automatically releases gases which are routed through large piping runs called flare headers to the flare stacks. The released gases are burned as they exit the flare stacks. The size and brightness of the resulting flame depends upon the flammable material’s flow rate in terms of joules per hour.
In order to keep the flare system functional, a small amount of gas is continuously burned, like a pilot light, so that the system is always ready for its primary purpose as an over-pressure safety system. The continuous gas source also helps diluted mixtures achieve complete combustion. Enclosed ground flares are engineered to eliminate smoke, and contain the flame within the stack.

The mud gas separator is used in a ‘kick’ situation to separate large volumes of free gas invaded in the drilling fluid.
Function of Mud gas separator
Mud gas separator also called poor boy degasser, Gus buster, which is designed to provide effective separation of the drilling mud and invaded gas from the well by venting the gas and returning the mud to the mud pits. Small amounts of entrained gas can then be handles by a
 liquid gas separator vacuum-type degasser located in the mud pits. The mud/gas separator controls gas cutting during kick situations, during drilling with significant drilled gas in the mud returns, or when trip gas is circulated up.
Mud leg height is an important parameter for the mud gas separator, you need to clear it during evaluation.
What is Mud leg?
The mud leg in the separator is controlled by adjusting the fluid level in the mud tank or by moving the separat6or up or down within the tank. Mud tank height can restrict the maximum mud leg obtainable for open-bottom mud gas separator.
Mud leg is an important part for mud gas separator, it is also called Fluid level. Fluids level is maintained in a float mud gas separator by a float/valve configuration. The float opens and closed a valve on the mud return line to maintain the mud leg level. Valves can be operated by manual linkage system connected from the float to the valve, or the valve can be air-operated with the rig air. Mud leg height can be controlled by adjusting the float assembly.
There are some inherent problems in the use of float-type mud gas separators. The manual linkage separator has experienced problems with linkage failure resulting in improper opening or closing of the mud return line valve. Air-operated valves fail to function if rig air is lost, resulting in no control of fluid level within the separator. Mud-return-line valves are prone to plug with solids, preventing mud flow back to the mud pits.
Gas Flow calculation is another important issue to evaluate the mud gas separator.
Usually we need to calculate the following items.

Vacuum degasser and poor boy degasser is both are degasser in oilfield, there are some differences some maybe confused.
How do the two degasser works and the difference
  This two pictures is the different work principle of the two digassers.
The left side is the vacuum degasser, and the right side is the mud gas separator(poor boy degasser).
The vacuum degasser suck the drilling mud and separated mud and gas by vacuum pump.
Our vacuum degasser operates on a “thin strata” principle. The drill mud enters the tank and forces it to flow and distributed to a layer of internal baffle plates engineered to allow the liquid inside the vacuum degasser to flow as thin film and is exposed to the vacuum within the vessel. This layer of mud allows the gas to escape or break out of the mud . The vacuum pump releases the gas and discharge it to the disposal line. Mud exits the vessel under the action of the venturi and is returned to the mud system.
The poor boy worked by the physical characters.
The GN MUD/GAS SEPARATOR (poor boy degasser) consists of a cylindrical pressure vessel in a fixed vertical position. Inside is a series of specially angled baffle plates, stepped from the top to the bottom. When contaminated mud is routed into the separator, it flows downward successively over each plate. During this process, the heads of entrained gases “break out.” The released gas is then carried by the vent lines to a remote location where it can be safely flared. Continue reading »

Solid control system, also referring as mud system, is used to separate the solids or gas from the drilling mud. There are several centrifugal mud separators such as hydro-cyclone separators (desander and desilter) and decanter centrifuge, and mud gas separator, which separate drilling mud and gas.
Hydrocyclone Separator
Hydrocyclone separator is always referring as desander and desitler, used after shale shaker in the solids control system. Usually the cone diameter is more than 6″is called Desander, and used as the second-control equipment in drilling operation. the cone diameter is less than 6″is called Desilter, and used as the third-control equipment in drilling operation. We commonly used 5 “and 4″ cone to separate solid-phase particle size 15-47μm in the drilling fluid.
Decanter Centrifuge
Decanter centrifuge are used to process unweighted and weighted, water-based and oil-based drilling fluids (muds). Mechanical energy is utilized to increase the gravitational force exerted on solids that are present in the mud system. Continue reading »

Mud gas separator sizing and design selection is important for petroleum well drilling.Welcome to consult GN for the right sizing and fit design for your mud gas separator in oilfield drilling mud.
Recent wellsite disasters have led to an increased emphasis on properly sized mud/gas separators. To assure safty,we
 Mud Gas Separator sizing design should know mud/gas separator technology and recommends separator configuration, components, design considerations, and a sizing procedure. A simple method of evaluating mud/gas separation within the separator vessel has been developed as a basis for the sizing procedure. A mud/gas separator sizing worksheet will assist drilling personnel with the sizing calculations. The worksheet provides a quick and easy evaluation of most mud/gas separators for a specific well application. A brief discussion of other mud/gas separator considerations is provided, including separator components, testing, materials, and oil-based-mud considerations.
The mud/gas separator is designed to provide effective separation of the mud and gas circulated from the well by venting the gas and returning the mud to the mud pits. Small amounts of entrained gas can then be handled by a vacuum-type degasser located in the mud pits.
