For earth surface engineering, the contractor no need to consider about combustible gas or explosive gas, like HDD no-dig engineering, piling engineering, tunneling engineering, waterway dredging engineering. But for deep drilling engineering, like oil & gas drilling, Coal bed methane drilling, shale gas drilling, all the motor and control panel should be ex-proof standard. The standard should also separately as per different geological conditions. Some security equipment is also necessary.
1) Mud Gas Separator ( poor boy degasser) — security equipment in solids control system for deep drilling
When gas cuttings happened to drilling fluid, the gravity and viscosity of drilling mud will be changed a lot and cannot satisfy the requirement for drilling, even lead to kick or blowout accident. The mud gas separator , made of high quality material , can be used to separate the harmful gas effectively.

A same decanter centrifuge will work differently by different operators. Because the professional maintainence is very important to protect the centrifuge and gives the decanter centrifuge a longer operation life.Following is two reminding for handling GN decanter centrifuges.
- 1)Protect the Centrifuge Bearing before Moving.
GN latest designed decanter centrifuge is fixed with tighten steel bracket belt to support the bowl assemly.Before moving the centrifuge, it is very important to fix the bracket under the bowl assemly by screws and make sure it is tighten enough,if the bracket can not support the bowl assembly tightly,operators can put some rubber on the steel bracket to make the bracket more tightly under the bowl assembly. And then tighten belt to prevent the rotation of the bowl during shipping from jobsite to jobsite.
2) To start the centrifuge,operators should disassemble the supporting bracket for the bowl, and remove the tighten belt,and rotate the bowl assembly by hand before start to make sure the bowl rotation is free.
3)Lubrication should be done regularly for the centrifuge as following.
If customers have any other questions for your decanter centrifuge,please feel free to contact GN representatives.We will do our best to support you and give you solutions.

Mud gas Separators is an extremely reliable, vital piece of safety equipment for today’s drilling operations. 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.
GN Solids Control also manufacture the solar charged electric flare ignition device to matching the mud gas separator to burn the gas.
Solar Charged Flare Igniter
As part of the requirement of the tender drilling contractor are required to provide PT PERTAMINA EP with a supporting letter from GN Solids Control.
GN mud gas separator is to separate gas inside the drilling mud vent to the flare line to burn it in the safe areas.
GN oilfield decanter centrifuges can be used in different applications for handling drilling mud for solids control and drilling waste management.
Take GNLW363 serires decanter cantrifuge for examsple, operator can set up the decanter centrifuge speed as following, it can used for following application:
PLC Decanter Centrifuge Speed
- Barite Recovery: Operator can run the centrifuge with G foce at range from 700-1000 G, and run the 14 inch decanter centrifuge at speed around 2000 RPM.
- High Gravity Solids(HGS) Separation:Operator can run the centrifuge with G foce at range from 1000-2000 G, and run the 14 inch decanter centrifuge at speed around 2500 RPM.
- Low Gravity Solids(LGS) Separation:Operator can run the decanter centrifuge with G foce at range from 1800-2300 G, and run the 14 inch decanter centrifuge at speed around 3000 RPM.
How to asjust the speed for decanter centrifuge?
The method to set up bowl speed for decanter centrifuge normally have three ways, one is to USE the VFD control system to adjust the frequency for the motors to control the speed for the decanter centrifuge, second is to use Hydraulic driven system to adjust the bowl speed and differential speed.Third, to change the centrifuge speed is to use different sizes of pulley and belt to change the speed.
GN offers decanter centrifuge for all above types to allow users to use the decanter centrifuges for different applications.
Decanter Centrifuge Feeding Pump speed and capacity.
To feed the GN 14 inch GNLW363 Decanter centrifuge, normaly we recommend to use GNG30-7.5 screw pump.The GNG30-7.5 screw pump is a positive displacement single screw pump, the capacity of the pump depends on the speed or the motor, the motor transfer the speed thru gearbox to the pump. For example, the ration of the Screw pump is 6/1 so if the pump motor run at 60HZ, that means the motor run at 1750RPM and the pump will run at 291RPM. And if the decanter centrifuge feeding pump run at 291 RPM with capacity at 30m³/h. And if adjust the VFD to run at 30HZ, the pump speed will be half capacity, around 15m³/h.
