Degasser type

Commonly, there will be poor boy degasser and vacuum degasser in drilling fluid solids control system. Especially in oil & gas well drilling. They are both useful to keep job site safe and make well drilling operation successfully.

As we know, “poor boy degasser” is our oral term. It should be called “mud gas separator”. Ye, it can separate quantities invaded gas from drilling fluids according to differential pressure between vessel inside and external environment while drilling.

Vacuum degasser

Poor boy degasser and vacuum degasser position design

Generally speaking, we treat poor boy degasser not only as solids control equipments but also as safety equipment in the drilling site. The poor boy degasser won’t be used all long time. Its position is ahead of Shale shaker. Since we must get rid of large quantities invaded gas to avoid blowout.

Regarding to the vacuum degasser, usually it isn’t used at the same time with poor boy degasser. It can only separate little quantity invaded gas. Vacuum degasser position is behind shale shaker and before mud cleaner or hydrocyclone desander, desilter. This will lead subsequent process more smooth and safe.

In fluid solids control system for oil & gas well drilling there will be various of configuration and design. However, the position for each equipment usually can not be changed.

Actually, each solids control equipment holding certain function and specific feature, presently the position design comes from long term improvement and practice. Also it is appreciated by users all over the world. If no accidence, the design on position won’t be amended

Degassers main specifications

The main specs we care are degassers treating capacity, the actual degassing efficiency, the gas flow rate, etc. For poor boy degasser, we can find clients pay more attention on “mud seal” or “mud leg”.

Usually, this is related with treating capacity and tank height.

GN solids control can supply not only solids control equipment, but also oil & gas drilling ralated equipments, such as mud gas separator,flare ignition device, etc.

Mud gas separator also called poor boy degasser, it is a kind of well-control equipments.  When harmful combustible gas is too much to result in kick even Blowout accident occcurred, mud gas separator must be applied together with electric flare ignition device.

GN ZCQ series mud gas separator have two types, one is manual-control, the other one is auto-control, the  pedestal can be made into fixed type or elevating type according to customer’s requirement.

Vacuum degasser is also called mud gas separator, but they are different equipments. When there is only a little gas invade drilling mud and the gas is not harmful combustible gas, vacuum degasser can be applied in such situation. At the same time, vacuuum degasser can be used as agitator with large power, suitable for variable kinds of drilling fluids circulation system.

Vacuum type degasser is the most common type, there is a new centrifugal  degasser applied.

Contact GN solids control for more information about vacuum degasser and mud gas separator.

Mud gas separator( also called poor boy degasser) removes air or gases (methane, H2S, CO2 and others) from drilling liquids. If the gas content in the mud is high, a mud gas separator or “poor boy degasser” is used, because it has a higher capacity than standard degassers and routes the evolved gases away from the rig to a flaring area complete with an ignition source.

 What is the features of GN mud gas separator? 1 Matched flare Ignition device available, to provide complete solution for you.

 GN Flare Ignition Device of blown down fuel gas is a kind of handling arrangement used in blown down natural gas, the tail gas from collecting and distributing station of natural gas and from refinery. And being a kind of security and environmental protection equipment, the flare ignition device can be used to have the blown down harmful gas ignited and burned to prevent the environment and security from being endangered. The flare ignition device, apart from being used in the refinery and gas distribution station, may be matched with Mud Gas Separator. And now, as a matured product it has been extensively used in petroleum drilling engineering.

 2 Coating and Painting:

 External coating 3 layers, Internal coating 2 layers.

 External coating:

Surface preparation: Commercial blast SA2, SSPC-SP6

Primer coat: (Kansai & Cosco)Japan Brand epoxy zinc-rich anticorrosive paint

Intermediate coat: micaceous iron oxide anchor coat

Top coat : aliphatic polyurethane top coat

The External coating system is composed of zinc-rich epoxy primer, micaceous iron oxide anchor coat and aliphatic polyurethane top coat, which is with advantages of good antiseptic effect and Durability.

Recently wellsite disasters have led to an increased emphasis on properly sized mud/gas separators. Mud gas separator is a device that removes gas from the mud coming out of a well when a kick is being circulated out.

 GN Mud gas separator has been designed to capture and separate large volume of free gases within the drilling fluid. Designed for high pressure wells, this unit controls the circulated gas to the surface separating the gas from the mud and vent it.

 Simplicity is the essence of GN design for mud gas separator. It can be knocked down for easy transport.

 Example1

31.5” Mud Gas Separator(ZYQ800) is a self contained unit that allows for easy mobilization. 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.

 The Mud Gas Separator is primarily used to separate and safely vent from the active mud system large pockets of free gas that may include toxic gases such as hydrogen sulphide

 31.5″(800Mmm) diameter by 108″ seam to seam vessel equipped with internal baffles, 5″ mud inlet, 6″ mud outlet with “J” tube design_Manages approximately 1056 GPM, and 36000 BBL/Day. Unit is designed to mount on top of the tank and secured into position. This allows the unit to be lowered to the bottom of the mud tank for transportation.

Oilfield drilling Poor Boy degasser (mud gas separator) is professional equipment to treat the gas invade mud. When the drilling mud result gas invade, the proportion of its weight and viscosity have 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. ZYQ series Gas-liquid Separator combined with the (Company site: Solids Control System

Oilfield drilling Poor boy degasser that removes air or gases (methane, H2S, CO2 and others) from drilling liquids. There are two generic types that work by both expanding the size of the gas bubbles entrained in the mud (by pulling a vacuum on the mud) and by increasing the surface area available to the mud so that bubbles escape (through the use of various cascading baffle plates). If the gas content in the mud is high, a mud gas separator or “poor boy degasser” is used, because it has a higher capacity than standard degassers and routes the evolved gases away from the rig to a flaring area complete with an ignition source.
