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.
 mud gas separator 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.

GN can produce 4 inch mud hopper(500x500mm), 6 inch mud hopper(600x600mm,750x750mm), usually we assembly the mixing pump and mud hopper together as a jet mixing unit. It is widely used in our HDD system. A butterfly valve is incorporated in the neck of the hopper to adjust flow and to close off the hopper after use.
 mud hopper Mud hopper usually used in mud mixing pump, High shearing mixer. Or as separated device matched with pump for bentonite configuration and mixing in mud mixing system. The working condition of mud hopper usually is mud density 1.5~2.8g/cm3, while mud viscosity is 60~120s. This is usual working condition to provide better performance as well as longer use life to save total cost on drilling.
GN mud mixing hopper are widely used in HDD(horizontal directional drilling) and oil gas drilling for bentonite mixing.Mud Mixing unit is combination of drilling mud hopper and centrifugal pumps,it’s mixing force comes from the centrifugal pump.

GN produced drilling fluids decanter centrifuge and the feeding pump. Usually screw pump is used in oilfield drilling as feeding pump of centrifuge, but sometimes we choose submersible slurry pump in the solids control system as centrifuge’s feeding pump.
G series single screw pump for pumping neutral or corrosive liquids, uncontaminated or abrasive liquids, liquids containing gases or which tend to froth, and liquids of high or low viscosity, including liquids containing fibrous and solid material. G series single screw pump Principal fields of application Food industry, Texil mill, Paper-making, Petro-industry, Chemical industry, Ship building, Build industry, Nuclear industry, Metallurgical and mine etc. It is designed according to Chinese standard.
EH series screw pumps are usually installed horizontally, have flange connection and may universally be used in all industries for handling non- viscous, neutral or abrasive media, with or without solid and fibrous matter.The EH design is available in 1-stage(6 bar), 2-stage(12 bar) and 4-stage(24 bar) pressure range.
Suction and Discharge ports can be interchanged by simple reversal of direction of rotation of pump.
 screw pump for decanter centrifuge Advantages of EH
- EH Pumps can be used with virtually any type of driver
- Available in numerous rotor/stator material combinations
- Ability to handle fluid gently and with extremely low shearing
- Various combination of casing materials available viz. CI, Carbon steel, Stainless steel etc.

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.

GN produced solids control equipments(such as shale shaker, vacuum degasser, desander, desilter,drilling fluids centrifuge, centrifugal pump, mud tank, etc) with high quality and competitive price. Our principle is “Quality first, Price second”.
For solids control equipments, there are 100 prices,and 100 quality in China.
If we divide China products quality into: A＞B＞C＞D
And divide China products price into: A＞B＞C＞D
And GN’s market strategy is to provide Quality A products with Price B.We look to profit from more orders,not to have high profit in few orders.
 Shale Shaker For example, one client found a shale shaker with only 70% price than GN’s, so he is not interested in working with GN, and go for the cheaper products, but after using, it always has problem of mud overflow. Maybe the problem is mud or shaker screens, or maybe it is because of shale shaker or improper operation. Until now he still have trouble of well working of the shale shaker.
