As more and more countries start to control the drilling waste and improve the standard of waste discharge in oil and gas drilling field, drilling waste management becomes more and more popular and important. Many companies have to or want to start their business for drilling waste management. But many clients do not have experience on it. They do not know how to choose the suitable equipment or systems for their activities.
As a worldwide famous brand on mud solids control and drilling waste management, GN Solids Control start its research and development department for drilling waste management and industry waste management for many years. Below is a brief introduction of normal drilling waste management equipment to help the users make decision.
1) High G drying shaker.
It is also named High G dryer, cuttings dryer. It utilizes high G force up to 8.0G to dry the cuttings. If there are big particles in the solids waste, high G shaker is requested. It can remove big size solids and even metal particles. The high G shaker can remove solids above 100 microns.
It is mainly used to treat the water base mud and water based mud cuttings. It can also be used for oil based mud treatment in some cases.
When the high G drying shaker is used to treat oil based mud and cuttings, it can only reduce the oil on cuttings (OOC) to 10 ~ 15%.
It is also called vertical centrifuge or vortex dryer. It utilizes centrifugal force up to 420G to separate the fine solids and recovery the usable drilling fluids. The screen opening of VG dryer is 0.5mm, 0.35mm and 0.25mm. It cannot allow big size sizes solids or metal particles; otherwise, it will be broken.
Vertical cuttings dryer is mainly used for oil base mud and cuttings. It can reduce the oil on cuttings to 3 ~ 5%. In this case, the solids discharge is on a very dry condition and it is easy for shipment. And the solids with 3~5% OOC can be discharged directly in many countries. If not, it is also easy for next treatment.
3) High speed centrifuge and big bowl decanter centrifuge
It utilizes the high centrifugal force to separate the very fine solids to 2～5 microns. It is used after high G shaker and vertical cuttings dryer, for further separation.
There are many other equipment used for drilling waste management, we will introduce in next file.

Gas Buster is also called mud natural gas separator or poor son degasser, which is a safety products used on oilfield to remove often the gas from drilling body fluids. The gas in the drilling fluids is coming from subterranean with very high pressure. The particular worse is that the gas is actually flammable and sometimes poisonous.
Where you can the locate the natural gas buster on an oilfield
Its well known that the solids control equipments prefer remove the solids from the drilling fluids so that the fluids could possibly be reused. Greatly could be preserved by recycling the drilling fluids. Strictly speaking, however the gas buster is not 1 type of solids control products, it always appears as well as solids control equipment. A number of mud engineers will set gas buster out of however ahead of the mud recycling tank, some ones even straight put the gas buster atop the mud tank . When there is drilling liquids coming out from the drilling pit with cut in ruthless gas, unless the gasoline is removed, the drilling fluids will be not be carefully guided to the shale shakers unit for recycling where possible.
How does gas buster job
The drilling fluids with good pressure gas will be to begin with guided to chock question for pressure relief. And after that the drilling fluids will likely be guided to gas buster. Inside the gas buster there exists a device named distribution water pipe which could decompose big mass gas into small propane bubbles. The gas pockets coming out of the distribution water pipe will directly float max and build up at the higher part of the gas buster boat and then guided out from the water line at the top of the vessel. Typically the slurry coming down will then copied to the shale shaker intended for mud cleaning system .
As mentioned before, often the gas separated by the fuel buster is always flammable as well as poisonous. It cannot be released to environment directly. The normal practice is to guide the propane somewhere 50-100 meters miles away from the rig and the burned by an igniter unit.
Gas buster and igniter device are not used often, they are just like the fire extinguisher. However , to a oilfield drilling site, especially a strong drilling site, they are fundamental.

Why GN decanter centrifuge running stable? As GN professional team equips many safety protection designs to support it.
Some of the safety features of GN design decanter centrifuge:
Safety feature 1: Vibration sensor for GN decanter centrifuge
GN decanter centrifuge is equipped with vibration sensor to protect the centrifuge from abnormal vibration. When the centrifuge is blocked or there is something wrong with it, there should be big and abnormal vibration. With the vibration sensor protection, the centrifuge can be stopped automatically in this condition to avoid further damage to it.
Safety feature 2: Bearing temperature protection of GN design decanter centrifuge. There are sensors equipped for the main bearings of GN decanter centrifuge.
If the centrifuge is not running well, or there is something wrong happed to the centrifuge, there may be not abnormal vibration, so the vibration sensor is not workable in this condition. But the bearing temperature may be increased. It means there is something wrong with the bearing. If it cannot be stopped immediately, it will damage the bearing and then further damage the centrifuge bearing base and impeller. With the main bearing temperature sensor, when the temperature is over the set figure, the PLC system will stop the centrifuge automatically, then operator can come and check the centrifuge.
Safety feature 3: Cover open switch
It is dangerous and prohibited to open the centrifuge collection box cover during shipment. All GN centrifuges equipped with cover open switch. In case the operator wrongly open the collection box cover, the centrifuge will be stopped automatically to avoid human hurting.
Safety feature 4: Overload protection.
In case the centrifuge is overload, if it cannot be solved on time, it may broke the centrifuge auger and bearings, and burned the motors. GN centrifuge are equipped with overload protection. When there is an overload condition, the centrifuge will be stop automatically for protection.
With all the safety features, GN decanter centrifuge can be running well in different jobsite.
