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 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.

Per experiences and calculated data, the drilling liquid occupies in any well drilling is between 4 percentage to 10 percentages, no matter in onshore drillings or offshore drillings. Considering its effects on the drilling operation performance, which occupies nearly 50 percentages, the drilling fluid is quite vital to the drilling.

GN Waste Management Equipment

That’s why, a professional drilling manager has to have a professional team for the drilling mud services, or find a qualified drilling fluid service company. In practice, drilling companies or drilling contractors always focus on drilling work, and employing a subcontractor for the solids control system. Each drilling rig has eight systems connected to each other, among which, the solids control system is comparably independent. An expertized drilling fluid company has the right personnel and suitable equipment, and more important, they know how to treat the fluid well.

A professional oil service companies provide following services:
1. Solids control equipment and services. The solids control systems help to treat the drilling fluid directly from the well mouth. It contains three or four phases for separation, including the shale shaker as the first phase, the desander cones as the second phase, the desilter cones as the third. Some include the decanter centrifuge as the forth one. In most solids control systems, there are mixing unit for adding more chemicals into the fluid when necessary.
2. Drilling cuttings waste management systems, in some countries, this part is also regarded as a part of solids control, because this is also for treating the solids from the drilling fluid. Those systems always contains the vertical cuttings dryer, the high G drying shaker and the decanter centrifuge.
3. Drilling fluid waste management, it is the further treatment for the drilling fluid. As the fluid has been used for a long time, this system uses some chemicals to flocculate the extra fine particles into larger ones before being separated out by a decanter centrifuge.
As one of the leading manufacturers of solids control and waste management, GN Solids Control has been providing lots of oil service companies in the world for all above mentioned systems and equipment. For more information or a formal quotation, welcome to contact GN directly.
