Just last week, GN Solids Control has finished a compact mud recycling unit, with full steps for separation for one of the largest oil giants in China. This system is to be transported to the jobsite by end of this year.

This system has 4 steps of separation, including:

1. GNZS703F. Shale shakers are always the first step for separation, because of GN shakers’ high G force and accurate API complied shaker screens, this shale shaker can efficiently separate out all particles larger than 100 microns, there in hence to help with prolonging the service life of the centrifugal pump after the shaker.

2. GNZJ703F-1S8N Mud Cleaner. Mud cleaner is a combined machine of desander and desilter, at a smaller foot print. It uses interchangeable shaker screens as GNZS703F, 2 centrifugal pumps are used to feed the desander and desilter respectively.

3. GNSP series Centrifugal pumps are also GN’s own products. For material choosing, GN used the high quality anti-weary material as pump body material by hard ductile iron alloy, and the main pump body is thicker than other manufacturers’. All GNSB series centrifugal pumps are using stainless steel mechanical seals.

4. Tank and skid for above mentioned equipment. Above mentioned equipment are located as 2 blocks. One block is a skid with lifting and anchoring corners just as a 20ft container, and the shale shaker and mud cleaner are located in the skid during transportation and operation. That design facilitates the operator for transportation or lifting the whole skid onto a tank, no to adjust each equipment or pipeline’s position.

5. A tank with compartments are designed to storage the mud from the shaker and from the desander/desilter. On below the tank, there are some slots for installing the centrifugal pumps. The whole outsize of the tank is also same as a 20ft container with container corners for lifting.

As the leading manufacturer of solids control and waste management equipment and also a professional separation solution provider, GN Solids Control has a products line covers the separation procedures and also the transferring procedures. GN Solids Control provides various pump for different applications including following:
1. Centrifugal pump, centrifugal pump is the most commonly used pumps in the oil and gas solids control industry, which is used for feeding the desander and desilter cones, for compensate the mud loss from the trip tank as trip pump, feed pump for the mud mixing unit for the mixing application and also plays as a role of charging pump. GN Solids Control produces the full range of centrifugal pumps from75kw to 7.5kw, equipped with mechanical seal, with high quality material for longer service life. All parts of GN series centrifugal pumps are interchangeable with Mission Magnum.

2. GN shear pump. Shear pump is not so commonly used as centrifugal pump. They are only used for shearing some special chemicals which are needed for large horsepower oil and gas drilling rigs.
3. Submersible Slurry pump. Submersible slurry pump’s applications in GN solids’ mud system and mud units are mainly those two: one is for centrifuge feeding in solids control systems like for the barite recovery and extra fine particle separation, or for the HDD mud recycling units, it is the second to none choice for transfer slurry from the mud pit to the mud system.
4. Vacuum pump. GN series vacuum pumps are the newest member among GN pumps. But it gained highest attention ever since its birth. Comparing with other pumps, the most obvious difference is that it has no motor. It is fully air driven and has less limitation for the solids size. In practice, it could handle material with particle size only a bit smaller than it’s pipeline diameter.

Although during the past 2 years, the waste management and environment protection proposals GN produced are occupying larger and larger share of all GN products, the traditional application GN Solids Control has been professional in has not lost it’s advantages. Recently, just when the oil and gas industry is picking up, GN’s international market is coming up again and a UAE client just purchased a 350GMP mud recycling system from GN Solids Control.
GNMS series mud recycling systems are one of the best seller products among all GN products, during those years, especially the 500 GPM mud recycling systems. In some jobsite, the 350 GPM mud system could serve as 500GPM mud recycling system, too.
This mud recycling system is combined by 2 phase separation equipment, plus a mixing unit. Depending on the limited space request on client’s jobsite, and also taking into consideration the transportation, the desander cones are not used in this system. For the first 2 level of separation, GN designed a double deck shaker, the lower shaker deck is served as shale shaker, with coarse meshes, .while the upper deck shaker is under the desilter cones, playing as the drying shaker for desilters.

On the other side of the tank, there is a mixing hopper, which is a common component of a mud recycling system for HDD projects. It is used to add and mix some necessary chemicals into the drilling mud.
Each year, GN Solids Control produces tens of mud recycling unit to the non-oil and gas industries, mostly for HDD, CBM, Water well drilling, TBM and Piling. All such mud systems could be grouped into 2:
1. Self-contained mud recycling systems with larger mud capacity and a mixing unit. Those systems, in application, are mostly used for HDD, CBM and etc. Normally, clients use a slurry pump to transfer mud from mud pit to this system and use mud pumps to suck out mud from the system.
2. Compact mud unit, without a mixing unit, mostly used for piling and TBM.

In order to reach some separation results, especially in case of physical separation, the shale shakers always play important roles and handles most of the separation work. GN Solids Control is a professional separation proposal supplier and has various models of shale shakers. Those shakers are widely used in oil and gas industry and other drilling works, like the HDD, TBM and industry separations.

GN DOUBLE DECK SHAKER

GNZS706E-HB Shale shaker, with 2 shaker deck and totally 6 pieces of shaker screens, is one of the best seller model among GN shale shakers. Main specification and features as below:
1. Shaker deck number: 2 decks.
2. Treating capacity: 120 cubic meters per hour.
3. Screen quantity: 6 pces, including 3 pieces of upper layer and 3 pieces of lower layer.
4. Screen size: upper layer size 2.0 m2, while lower deck layer 2.63m2.
5. Vibration motors, from Italy Brand Oli, with 1.94kw of each motor.
6. Vibration amplitude from 4.14 to 5.96 mm.
Double deck shaker is a compact solution. In some cases, when operator has a limited space or considers to reduce the power horse of the whole system, but meanwhile, he requests to meet a certain treating result. A double deck shaker is a perfect solution. The upper layer screens are using coarse meshes and lower layer screens are finer. But there’s no need for a feeding pump as is used for feeding the desander or desilter cones.

GN Desander and Desilters
Besides the double deck shaker, GN has other models of shakers, per their screen quantities, there are:
1. GNZS752E-DM, a small shale shaker with 2 pieces of shaker screens, each screen is sized as 750x900mm, its vibration motors are 2 motors each of 0.75kw. it could treat a small capacity of 45cbm/hr.
2. GNZS703E-HB/DZ, a small shale shaker with 2 pieces of shaker screens, each screen is sized as 750x900mm, its vibration motors are 2 motors each of 0.75kw. it could treat a small capacity of 45cbm/hr.

GN Solids Control is one of the leading brands for solids control and waste management system, and second to none ranks among Chinese manufacturers in this industry. A lot of worldwide famous oil companies and oil drilling companies are using GN equipment and comprehensive solutions, including SINOPEC, CNPC and COSL. Recently, GN delivered main equipment for 2 sets of drilling cuttings waste management systems for CNPC.

GN BIG BOWL CENTRIFUGE FOR CNPC

Drilling cuttings are solids discharge from the drilling rig solids controls system, from the shakers, desander and desilters. After the solids control system’s first 3 phases separating, the drilling fluids are returned back to the system without the solids particle. But the separated-out particles are still too wet. For one thing, it is a waste for valuable drilling fluid. Secondly, it could damage to the environment if disposed directly. That’s why it is not only necessary but also mandatory to do some further treatment for the drilling cuttings.
GN Solids Control has zero discharge solutions for both WBM and OBM. And this order, combining the vertical cuttings dryer and decanter centrifuge, is for the oil based mud. A vertical cuttings dryer is specially designed for the oil based mud separation. GNCD930 series vertical cuttings dryers could dry the drilling cuttings to reach OOC value to 5%. The vertical cuttings dryer is running as the drying step of a washing machine. The vertical cuttings dryer is equipped with a screen basket with certain mesh number. Fluids pass the mesh and collected, while cuttings are stopped by mesh and falls down.
GNLW series decanter centrifuges with VFD control panels are used after the vertical cuttings dryer to remove the particles from 2 to 5 microns from the liquid. Most common model is GNLW363CG-VFD, a medium sized centrifuge with a high rotating speed. But for bigger treating capacity, GN has GNLW453C-VFD and GNLW553-VFD available, both of high rotating speed while bowl sizes are respectively 18 inch and 22 inch. In this project, clients chose GNLW453C-VFD.
Pls contact GN for more information.

The service companies or project contractors are always very strict on choosing equipment manufacturers, because a good manufacturer is not only about the image and reputation, the more important thing is, the good performance of the equipment. Like for the oil and gas drilling, working on the rig means continuously operating and any unexpected failure comes at big cost.
In many projects which are in need of separation works, the shale shakers play a very important role. For example, in oil and gas drilling solids control projects, the shale shaker take over more than half of separating work, and in HDD or TBM projects, a shaker is always the first or even only separation step, even in drilling cuttings waste management projects, a high-G shaker with a 8.0G force are head in the queue.

GN NEW ORDER FOR SOLIDS CONTROL EQUIPMENT

GNZJ series shale shakers have following features:
1. High G force to ensure a good performance and good separation results. With Italy brand Oli as professional vibrating motors, GN shale shakers could reach a G force up to 7.5, and according to the jobsite condition, this G force is adjustable.
2. A strong structure of shaker deck made of stainless steel, instead of normal steel. Only a strong structure could endure the high G force vibration. That’s why GN shale shakers have a longer service life.
3. API RP 13C shaker screens with composite material frame. GN now make all its frame screens with composite material frames, it has a longer service life than steel frame ones, and the conductance is much larger. With same screen area, the unblocked area is much larger than steel frame ones.
Those above mentioned are only several features and advantages of GN shale shaker and shaker screens, since space here is limited, if you need more information about GN company and products, welcome to visit our website or contact us by email, telephone or fax directly.

In most of countries in the world, environment protection is very important for all industries with very strict laws. For the drilling projects, the separation standard is evens more. That’s why, GN became one of the most well-known brands during past years and its adjacent countries for the ideal separation solutions in oil and gas drilling industries and other drilling projects like HDD, TBM and etc, and even for the construction works.
