Drilling waste management system can be divided into 2 kinds when there is a drilling rig for oil and gas. It depends on the procedure of the rig’s solids control system and also the components used during drilling. When there is a drilling rig, there must be some drilling fluids cycling in a system, which is called a solids control system. Just as its name, this system is used to control the solids content in the drilling fluids and to remove the waste particles as many as possible in order to make sure the drilling fluids to reach the standard for reuse. Those waste solids are sands and small stoned brought by the drilling bit from the underground, which are of different sizes. In order to remove them, the solids control system is designed into several stages based on a certain particle size range: shale shaker, desander, desilter and decanter centrifuge.

The shale shaker is the first stage, which is a physical separating with simple principle: vibrating. Normally, the shale shaker can remove particles larger than 100 microns. And the actual separating point is determined by the shaker screens’ API number, which is chosen by the end user. Of course, there is a curve between capacity and cutting point, the finer the separating result is, the smaller capacity it reaches. And it is the shale shaker which remove the most solids particles. But there is a problem, that the particles removed by the shale shakers are still too wet, containing a certain amount of expensive drilling fluids. That’s why it is necessary to have some further treatment of the drilling cuttings from the shale shaker.
Besides the complete solids control system, GN Solids Control also provides professional solutions for drilling cuttings waste management. Just recently, an European client purchased such a system including following:

1.Cuttings feeding section: this section is used to collect the wet cuttings from the shale shaker and feed to the first stage of separating in a waste management system.

2.High G drying shaker section: it is especially designed for the water based mud, it looks similar as a normal shale shaker but with a higher G force.

3.Vertical cuttings dryer section: a vertical cuttings dryer serves same function as a high G drying shaker for the drilling cuttings under condition when oil based mud is used in the drilling system.

4.Screw Conveyor section: this section is used flexibly for transportation purpose between the treating equipment.

In this case, even when the drilling site uses both WBM and OBM, the waste management sections can be used flexibly.

As one of the leading separation solution provider in the world, GN Separation is becoming more and more popular among clients. In a recent project, GN has delivered to New Zealand a complete system for the slurry dewatering in a construction field. This system contains following equipment manufactured by GN:

1.Coarse screening stage, a GNLMP1536 Mining Vibrating Screens. Shale shakers are one of GN core products in oil and gas solids control industry, and the mining vibrating screens are another group similar with shale shakers. Comparing with shale shakers, the mining vibrating screens are just bigger in both machine size and screen opening sizes. In a slurry dewatering project, they are always used as a coarse screen at the very first stage for separation.

2.Double deck fine screening GNZJ706. The double deck shaker screen are used for fine screening. This shaker is equipped with 2 deck of shaker screens with different screen openings. In this case, the capacity is larger than the single deck one with same power consumption and space.

3.Desilter unit GNZJ594-12N. The desilter cones are used for separate out the particles around 20 microns by centrifugal force. And under below there is a vibrating screen for drying the particles. Liquid size is discharged to next step.

4.Big bowl centrifuge GNLW553D. The decanter centrifuge is used for fine separating for particles from 2 to 5 microns. GNLW553D decanter centrifuge has a bowl of 22 inch diameter and the length-diameter ratio is 3.

5.Chemical dosing unit. When there are extra fine particles in the liquid, the chemical dosing helps to flocculate the extra fine particles to be big enough for the centrifuge.

GN has a technical team with years of experiences for designing customized solutions in fields as solids control, waste management, dewatering and oily sludge treatment and mining related with the separation purpose.

One unit of ATEX certified vacuum degasser and mud gas separator are ready for shipment to Europe client.
Mud gas separator, also called poor boy degasser, GN ZYQ series atmospheric pressure mud gas separator is a specialized equipment for primary degassing of gas cut drilling fluids, mainly used to remove gas cut drilling fluids with a diameter of approximately ≥ φ 3mm large bubbles. These large bubbles refer to the expansive gas that mostly fills a certain section of the wellbore annulus in the drilling fluids. If it is not removed, it will easily cause a kick or even spray out of the surface of the drilling disc.
GN ZYQ series atmospheric pressure anti hydrogen sulfide mud gas separator is made of high-quality materials, which can effectively prevent the erosion of harmful gases and ensure the safety of human machine production.

Features of GN mud gas separator:

1. The poor boy degasser adopts bottom drainage to control the height of the working liquid level, ensuring a constant liquid level in the separator and solving the problem of sand accumulation in the tank;
2. The poor boy degasser tank is equipped with a dedicated gas separation channel, which allows for smooth gas evacuation and improves gas treatment efficiency;
3. The mud gas separator adopts physical impact separation to ensure the gas separation effect;
   GN ZCQ series vacuum degasser is mainly used for separating gas from drilling mud, which is specialized equipment developed based on various types of vacuum degassers a for treating gas immersed drilling fluids. Suitable for various mud recycling systems, it is very important for restoring the specific gravity of mud, stabilizing the viscosity of mud, and reducing drilling costs.
   We will install ATEX certified electric motor and control panel for the vacuum degasser, and also for the vacuum pump motor. No extra jetting pump is required for the vacuum degasser’s operation.
