Dry Location Mud System

Offshore and onshore rigs walking water bsaed programs where there are restricted or zero-discharge ideas, the place there may be a scarcity of water, and or the situation it is significant to drill with a low-density or delicate water approach. Colloidal-size particles assemble up inside the fluid procedure, reqruie dilution which cna create immoderate fluid volumes. 
It's a be aware of undeniable undeniable fact that the presence of colloidal dimension particles can degrade the effectivity of water situated driling fluids, requiring high-priced dilution to keep the compatible density and rheological residences. This in flip end result in higher  volumens of waste which have obtained to be handled and sent for disposal.
The portable containerized dewatering procedures can do away with these sufficient particles by means of a procedure of chemically extra compatible centrifugation that is signivicatntly further mighty and low cost than a immoderate percent centrifuge on my own. This offers operators a robust software for maintaining excellent drilling fluid residences. While minimizing drilling fluid waste and lowering cleanup, remedy, and disposal bills. A few designs of dewatering units are availbe to go well with any onshore or offshore rig requirement.The main progress can divided to parts:
1. Dilution 
For some projects, fluids are extremely high contents of fine solids, also no other easy ways to do this quickly, then dilution is one. Old fasion, but quick, easy, sometimes, the most important thing is, it works.
2. Coagulation
When we have a dewatering unit container, normamly coagulation and flocculation unit are included, and normally at higher concentrations, the inorganic salts can form large precipitates, called sweep flocs. 
3. Flocculation
This is a more commen progress in all the separation works. The polymer forms bridges between the coagulated particles, and enabling them to physically join together into larger porous three dimensional structures known as floc.
4. Centrifugation
The final step is done by decanter centrifuge. Where finally the solids are separated.

Cycle of cleaning for the drilling fluid

Concept: The cleaning cycle of drilling fluid is to remove the harmful solid debris, reserve the clean drilling fluid to meet the demand of drilling fluid spec under the drilling process. Drilling fluid cleaning system is the term of all drilling fluid solids control equipments used in the oil drilling.

Function: To prevent the oil well from clogging, breaking, and decrease the drilling torque and friction resistance, reduce the pressure fluctuations of the empty suction, increase the drilling speed, extend the drilling bit life of use, and reduce wear and tear of the equipments.
Methods: The usual methods are mixture-thin methods, swap methods, machine methods and additive-chemical methods. Use different separation function machinery is  machine method is by using screening, centrifugal separation and gravity separation to separate the solid phase according to the different size and density, therefore, to control the solid phase in the drilling fluid.

1 The technical process of the drilling fluid cleaning system and the combination of the fluid cleaning equipment.
The technical process of complete group of drilling fluid cleaning system should meet the specification of five level solid phase control (screening, degassing, desanding, desilting, centrifuge) and the provoke the drilling fluid. The merger of each solids control equipment is very important, the through out of one to five level of mud cleaning equipment should each work with each other, and the spacing of the proper distance were is appropriate.  To have certain repeating cleaning during the cleaning process, make the smaller particles of the processing incomplete in the up one had been disposed in the next solids control equipment.


2 Drilling fluid cleaning cycles

The mud back from the opening of well through the pipeline and conveyed the drilling fluid to the shale shaker. The first phase of cleaning completed by shale shaker, then entered the mud tank, the drilling fluid flowed from the mud tank through the tank slot into the desander and desilter (if detect the present of gas, vacuum degasser will process to remove the gas) the fluid after processing of the centrifugal steps and through the tank slot enters the inhalation cabin.  The cleaned fluid then will reuse for lubricate and cooling the drill bit.

Decanter Centrifuge for Dredging Slurry Separation

GN Solids America has 3 sets decanter centrifuges in Houston, they are able to be utilized not just for oil & gas drilling, horizontal directional drilling, CBM, geothermal drilling, urban construction, mining exploration, additionally, it can use for biological sludge or dredging slurry separation project.

GNLW363CG premium decanter centrifuge is now the most advanced version high-speed decanter centrifuge so we already offered over 40units in jan.2015; they were shipped to Africa for a drilling mud service company. Lots of enhancements are requested the up-to-date design, for instance, special ceramics card inserts are requested mud distribution port, tungsten carbide tiles for additional reliable protection from the screw, Pneumatic spring design can be used for HSE purpose. The brand new version centrifuge performance is area demonstrated by lots of clients from rig site.

Before installing of a decanter centrifuge towards the dredging slurry separation system, a slurry lab analysis is needed to obtain the flocculation solution and solids weight and dimensions. The reason to make use of the centrifuge would be to separate the solids whenever possible making it dry enough for landfilled, and obtain relatively water that is clean to empty off and away to the dirty system or to the river or lake. Before feeding the biological sludge in to the decanter centrifuge, you'll need a scalping process to separate the large solids, which could make sure the proper performance from the centrifuge and stop it from screw broken extremely fast.

In comparison with using the traditional filter press, decanter centrifuge is less energy consumption and fewer cost, and also the dealing with efficiency is greater. However the solids released is less dry in comparison using the filter press, but when for land filled or construction purpose, the solids are dry enough.


Now GN solids America offer both purchase and rental method of getting the decanter centrifuge, please make a connection with our sales for that rate and term.

Water based drilling cuttings treatment

GN designed vertical G dryer waste management system can be used as both water and oil based drilling cuttings, and also the area test outcome is demonstrated effective. The conventional vertical G dryer drilling waste management system including: verti-G dryer GNCD930D-VFD, decanter centrifuge GNLW363CG-VFD, Nemo pump GNG30-075 for feeding the centrifuge, Nemo pump GNG10A-040 for flushing the VFD decanter centrifuge and vertical cuttings dryer, oilfield 3-runner design skid, V type liquids collection tank and some spare parts. This kind tank is for easy tank bottom cleaning and preventing accumulation of solids to the tank bottom.


We've specifically designed drilling waste management system for water drilling cuttings, the advantage to try to get this technique is:

1 Use Hi-G dryer to rather than Vertical G dryer, decreasing cost and less the facility consumption

2 decreasing the eliminating pump for that vertical G dryer

3 G-force of Hi-G dryer can achieve 8.0G max, with 4-panel shaker screen and a pair of 0.73m2 large screen position for better separation. After treated by hi-G dryer, the liquid is feeding to decanter centrifuge directly.

But in comparison with Hi-G dryer, verti-G dryer treated the cuttings much drier, the solids can be taken off directly by truck, however the solids separated by Hi-G dryer still remain around 40% humidity.

In water based drilling mud treatment system, the centrifuge is generally placed on the greatest telescopic frame for much better solids discharge. However the shale shaker might be using it the low stand.

But when for oil based drilling cuttings, Vertical G dryer management system is the greatest option, we've utilized it in lots of rig sites to check its performance, its demonstrated good based on our client’s feedback.


To check on GN vertical cuttings dryer performance within the rig site, please look into the video from GN website in the video page.

GN Mud System for 2000HP Drilling Rig

Each year, GN Solids Control design and manufacture many teams of oil and gas solids control devices for customers from abroad and domestic market. For GN Solids Control, GN can offer mud recycling systems for drilling rigs for example 650 HP, 750HP, 1000HP, 1500HP or 2000HP.

Just take 2000HP drilling rig for example, GN mud system can cope with 300m³/h. Usually, GN mud product is composed with 7 mud tanks: trip tank, shale shaker tank, centrifugal tank, mixing tank, shearing & reserve tank, and in addition the reserve tank. Suction tank can also be utilized while the whole system connects using the ruthless mud pumps and provide drilling liquids for that drilling rig.

For that trip tank, the max overall dimension is 6.5 X 2.95 X 2.37m, that is about 12m3. The trip tank is outfitted having a mud agitator and mud gun.

The shale shaker tank and the centrifugal tank can also be known as the treating tank. Both of these tanks are outfitted with shale shaker, mud cleaner and centrifuge to split up solids previously mentioned 100 micron to five microns. With these solids control devices, the mud could be released, and clean drilling liquids could be utilized again.

Because the drilling liquids is essential for each drilling process, to add some chemicals for example like barite, bentonite clay or something like that else. So a shearing tank and mixing tank can also be very essential for this solids control system.

After fully shearing or mixing the drilling liquids, the drilling mud could be storage inside a tank and prepared for more use. And also the mud agitator is playing an essential part in drilling liquids storage.


Whenever we connect two parallel ruthless mud pumps using the mud tank, we usually named the tank like a suction tank. Both of these mud pumps can suck the drilling liquids in the mud tank and supply clean drilling liquids towards the rigs.

The choice of dimension for Mud Tanks

Mud tanks are the base of a drilling mud system, regardless of oil and gas drilling mud solids control systems, or HDD or CBM or TBM, or whatever.  When there's drilling and there mud can be used, it's important to possess mud tanks.

It's not a difficult job for an engineer to create a mud tank using the modern soft-wares like AutoCAD or three dimensional drawing tools, but exactly how to assist the client to obtain an ideal tank in the beginning time? May be the asked for storage capacity of tank enough for design? GN Solids Control shares some suggestions.

1. When the first is requesting a solids control system for oil and gas drilling, this means the drilling mud comes from the well hole directly. Within this situation, we have to consider the weir height of shale shaker when selecting the peak of mud tanks. If the entire height of shaker weir and tank height is simply too large, it's possible that the mud can't fall in the pipelines from well mouth. This tip is particularly for workover rigs. For meeting customers’ different demands, GN has designed its shale shakers to supply several optional weir types.

2. Throughout transportation, what equipment within this system might be taken apart, while which equipment has to be fixed on tank and moved together? Actually, mud agitators will always be on mud tank, while shale shakers and mud cleansers will always be removed temporary.

3. Can there be any legal requirement in the users’ local for that biggest width or biggest height? This should be taken care.

4. just in case of worldwide business, the machine have to be shipped by ocean. What type of ocean shipment will the consumer accept?


Obviously, the storage capacity can be the fundamental requirement which needs to be meeting in the beginning stage. GN always believes to supply the clients with best and appropriate solution.
