GN Drill Cuttings Solidification Unit to Africa

Increase your environmental friendly drilling efficiency with GN Solids Control  products, one of the most important equipment is the Solidification / Stabilisation unit. The drill cuttings solidification unit is advanced and unique, which is quite flexible comparing the waste cuttings solidification plants.
Solidi cation – Is an absorption process where contaminants, typically oils, are taken into the absorbent material in the same way a sponge takes on water. In general, solidi cation is the addition of absorbents such as soil,  y ash, kiln dust, cement, clays or sawdust to the drilling waste management . The solidi ed product will have improved properties such as strength, compressibility and a reduced permeability.
Stabilisation – Is an adsorption process whereby contaminents are electrochemically bonded to the stabilising agents. Contaminants that are stabilised within the matrix are less likely to be released into the environment. This process is particularly relevant to the stabilisation of heavy metals and oils that would otherwise be rapidly available to the environment through leaching.
The adeptness to coalesce or stabilise a accurate decay beck and the e ectiveness of the analysis is abased on the decay blazon and analysis reagent factors. Typically, adumbrative samples of the decay are class activated to actuate the a lot of acceptable conception above-mentioned to eld implementation. Selection of the conception is commonly based on key belief such as leachate superior and backbone of the nal product.

Solidi cation and stabilisation generally requires the use of specialised accessories and actinic reagents. The processes absorb signi deceit abstracts administration upstream and after of the bond unit. Some decay streams may accommodate contaminants that can arrest the solidi cation/stabilisation processes.
For the solidication / stabilisation action to yield abode it is important to carefully adviser the decay produced at the rigsite for levels of alkali baptize and oil. This will advice to minimise the use of reagents and optimise the process, thereby abbreviation costs and the ecology impact.

Thus, it is with the accomplishment and ability that Scomi Oiltools has developed over the endure 20 years that allows us to, accommodate safe, amount e ective and environmentally complete solidi cation and stabilisation processes.

Shearing pump is also always equipped with mud hopper. With the impeller material of high wear resistant cast iron, the shearing pump is used to shear the polymers that used in the drilling mud to keep proper mud specific gravity. GN’s shearing pump is available as a belt-driven or diesel-driven package including hopper, mud gun and transfer line orifice plate.
GN’s PD pump is a single screw pump. This pump is an ideal chosen for feeding to decanter centrifuge unit as it transfer the drilling mud without shearing and agitating. This pump, with stator material of elastomeric material, has particular advantages to transfer fluids of high viscosity and hard suspended particles included.

Vertical submersible slurry pump is another choice as feeding pump to centrifuge. This pump is always installed vertically to transfer medium with high concentration particles. Submersible pump is also widely used to transfer the mud from mud pit to the shale shaker in the HDD mud recycling system.

Dewatering System for Water Hammer

Not only drilling, whenever there is a construction work, or some work, there must be some waste generated, planning before proceed have been more and more important. Some clients who is using water hammer, also is going to do with the waste, and reuse the water.
As we all know there are 4 basic rules of waste handling to make it envronmental friendly. Reduce, reuse, recycle, recover. For water hammer, one of the most important reason is we need to recyle and reuse the clean water.
Reuse – solids control equipment is key to the reuse strategy.  Poor solids control efficiencies will lead to more solids entering the active system, further reducing their particle size, and ultimately resulting in the requirement to dump, or to dilute, thereby increasing volumes and costs, all of which have a negative environmental impact. 
The water hammer which is normally more expensive than the normal drilling rig, especially for the use of the water, not drinking water but need to be as clean as possible.
2015.11.16 GN mud system with shaker and centrifuge
Therefor now we are deliverying one system to Europe, which is used for water hammer project. Containing:
1) Double deck shale shaker: GN double deck shale shaker can remove the solids in very good performance, top section screen with sieve screens remove most of the big particles. 

2) Decanter centrifuge: GN decanter centrifuge is used to remove the fine solids, min separation points about 2-5microns. Sometimes it need to be used with polymer, the dewatering unit, to make sure we get the better result.

3) Screw pump: screw pump feed for centrifuge. The pump from GN is made by German Netsch, NEMO pump makes sure the performance of centrifuge feeding.

4) Mud tank skid: All equipment is mounted on one mud tank, which is also able to be customized. Normally minimum requirement is to lower the transportation cost. 

Keep tune to GN news, then we can keep you updated on the on site performance.

Shale shaker purpose

The shale shakers are mainly powered by the rotation motors to rotate and produce the periodic changed passivity force, drilling fluid that contain solid phase pass through the mesh screen, do the forcing movement on the mesh surface, and then the solid phase debris with various size will be filtered. The separation sizes and through put of the shale shakers is the most important factors of making use decision. The technology level of shale shakers mainly show at the treating capacity, the stability of filter debris, the life of operation and the flexibility of operation. The managing ability of shale shakers is related with the structure of shale shaker steel body, the movement arrangement, the vibration frequency, the vibration intensity, the working area of shale shakers and the degree of thickness. In order to make the shale shakers match with the drilling machineries, the maximum outputs of the drilling pumps and the quantity of drilling cuttings filtered must be considered.
Shale shaker is one of the main products of GN solids control .GN  sell a series of solids control equipment and drilling waste management equipment including vertical cuttings dryer , shale shaker , screw conveyor , shear pump , oilfield shale shaker , mud cleaner , desander and desilter , vacuum degasser , poor boy degasser , decanter centrifuge , mud tank , mud agitator , etc .

The classification of shale shaker

It depends on the movement arrangement; the shale shakers can be grouped into round screen shaker, the common elliptic screen shaker, linear screen shaker, equilibrium elliptic screen shaker. The common elliptic screen shaker: also can be called the disequilibrium elliptic screen shaker, there is a exciter devices fixed right above of the screen box , the screen boxes may tilt an angle, use the leverage of the gravity, avoids the sand having the tendency of back flowing. From this, the tilt of the screen boxes really improved the flowing performance of sand, but the disposed amount of the drilling fluid reduced, this is the main disadvantage of the common elliptic screen shaker. The linear shale shakers: Two main axises with eccentric blocks do synchronous reverse rotation to produce the liner vibration. Because the direction of the liner shale shaker is unchanged, which makes the debris difficult to fall through, and then the screen paste aspect appears, which makes the valid over flowing area of screen and throughput reduced. When the number of screens increases, the aspect of screen paste will be more serious. So when the linear shale shakers use the super fines screen, it could not meet the requirements of the using amount of drilling fluid.

GN Series Pumps Used for Solids Control and Waste Management

Besides the main equipments used for solids control and waste management systems and HDD, CBM, Piling drilling projects, like the shale shaker, desander, desilter, mud cleaner, decanter centrifuge and vertical cuttings dryer, GN also produce suitable and reliable auxiliary equipments including mud agitator, mud gun, jet mud mixer and various of pumps.
Below are some popular pumps and their applications for your information:
1. centrifugal pump GNSB Series, which is also called sand pump. It uses centrifugal force to suck the material and feed to the main equipments. In a complete system, it is widely used like the desander cones feeding pump, desilter cones feeding pump and also the mixing pump for the jet mud mixer. In trip tank for a large solids control system, centrifugal pump is also used.
In a mud recycling system for the HDD, CBM, TBM or Piling, in most cases, centrifugal pumps are used as desander or desilter cones feeding pump also, and also mixing pump for the jet mud mixers. Sometimes, per client special request, it could be replaced by a horizontal slurry pump when serving as desander or desilter feeing pump.
shear pump1
2. shearing pump, plays similar role as centrifugal pump, but in some special chemical transportations, it is feeding pump for jet mud mixer also and because of the different design, it could also cut the chemicals during transportation.
3. submersible slurry pump, it serves mainly 2 applications in GN series solids control system and waste management systems, the first one is centrifuge feeding pump for GNLW363 decanter centrifuges, GNLW452 decanter centrifuges and etc. The second one is the feeding pump for a mud recycling system for HDD, CBM, TBM and piling works. Unless the oil and gas drilling rig jobsite, where the drilling mud could flow directly to the shale shaker, in such mentioned projects, the mud for treating mostly comes from the mud pit. A submersible slurry pump can help to suck mud from the mud pit to the system.
4. screw pump or called mono pump. GN is not manufacturing this screw pump, but in order to match suitable screw pump for the centrifuges, GN cooperate with the German brand Netsch. Screw pumps are most suitable solution for feeding the decanter centrifuges.

GN Vacuum Degasser, Efficient and Economic Solution

In the complete solids control system for the drilling rigs used in oil and gas field, there is an important equipment designed between the shale shaker and the hydrocyclones, which is not the treating equipment, but it is used to help the treating and protection the operators and the efficiency of the complete separation process. It is Degasser, used for discharge the gas bubbles in the drilling mud.
It is located behind the shaker, because the drilling mud fed to the shaker is directly from the well, and such drilling mud contains lot of bubbles, during being treated by the shaker, some bubbles may deleted themselves, and meanwhile, new bubbles may emerge on the shale shaker step. After the shale shaker, the following equipments all need feeding pumps, especially centrifugal pumps. The drilling mud containing the gas bubbles may harm the centrifugal pump, or at least, deduct the efficiency of the pump.
What kinds of Degassers is popular?
Mainly there are two types of Degassers, one kind is designed and provided by US or European companies, they are efficient and welcomed by many end-users in the oil and gas field solids control systems. But they have a clear shortcoming, that it consumes a large amount of electricity, because it needs a large power centrifugal pump for feeding.
In order to avoid the above mentioned shortcoming, Chinese manufacturers designed another kind of degasser, which is vacuum degasser, by using the vacuum sucking force, it could be a  self contain unit and sucks the drilling mud in and do the degassing work. It is as efficient as the US and European ones.
What’s GN’s Advantages?
As the TOP solids control company in China, GN is professional in all solids control equipments not only the vacuum degassers but also all related equipments, including the shaker, degasser and desilter. GN is far ahead of other Chinese suppliers and are competing with USA and European solids control suppliers in many field, including the US market and in Houston.
