EMEC, which is short for Egyptian Mud & Chemical Engineering Company, is a well known company with more than 25 years history for providing specialized drilling and production solutions, and has a certain influence on oil and gas companies in Middle East and African companies.

GN Solids Control, as the second to none Oil and Gas solids control and waste management system and equipment company in China, has been working with EMEC for years. The both parties know each other very well. By end of last year, EMEC has launched a big order to GN Solids Control, for a large batch of decanter centrifuges. This celebration, is not only for the partnership between EMEC and GN Solids Control, but also the celebration for delivery of some of decanter centrifuges.

The owner of GN, Mr Zhou and the Exclusive Manager Mr Amir from EMEC attended the celebration, and also the head quarters of GN, and engineers from EMEC. During the celebration, Mr Amir and Mr Zhou respectively gave their sincere speeches about the future of cooperation. Both parties surely believe that, GN will bring to market more and more high quality equipments and products, and the cooperation relationship between the two companies will be brighter. Mr Amir also appreciated the efforts from GN staff for successfully producing so many high quality decanter centrifuges.

That is exactly fact. His order came just before the Chinese New Year, in order to deliver the order in time, GN staff, especially the producing department, sacrificed their holiday and adding working hours in shifts. It is every GN person’s belief that the customers’ need is the most important.

GN also appreciates EMEC’s support and trust for a private owned company. And we have reason to believe that, the future cooperation between the two esteemed companies will be brighter.

As GN is manufacturing increasingly more mud tanks each year, more clients from abroad are requesting GN Solids Control Co. to provide his technical solutions for his customers. For any salesperson, to know how to calculate the effective of mud tanks by a fast way is essential. Clients are going to be astounded by an educated purchase.

So today we have prepared to share some methods to calculate the effective amount of GN tank.

The GN tank’s effective volume is dependent upon three factors: the first is the interior effective length, the second one is the interior width, and the third one is to be the height of corrugated board. Therefore the volume equals towards the product of those three factors.

If this involves container type tanks, the effective length is equivalent to the particular entire container. However, for any skid type tank, the effective length ought to be subtracted by 500mm because we have to go ahead and take skid parts into account.

If the centrifugal pump is installed on the skid, the effective length ought to be calculated in by doing this:

1. The centrifugal pump is installed flatly

while a pump is installed flatly, what this means is that it’s align using the length direction from the tank, so a pump with 37kw motor is visible as taking the size of 2.5m, and forces above 45kw ought to be subtracted by 2.8m for other pumps. Besides, if you find two paralleled pumps, the tank length ought to be subtracted by an additional 300mm.

2. The centrifugal pump is installed vertically

But when the pump is installed vertically towards the direction of tank’s length direction, 37kw motor is going to be calculated as 1m and 45kw motor (or over) is going to be treated as 1.3m.

A hydrocyclone is device that removes large cutting from the whole mud cleaning system. The desander should be located next of the shale shakers and degassers, but before the desilters or mud cleaners. A volume of mud is pumped into the wide top section of the hydrocylone at an angle roughly tangent to its girth. As the fluid flows around and slowly down the inside of the cone shape, solids are separated from the liquid by cycleclone forces. The solids continue around and down until they exit the bottom of the hydrocyclone (with some with small amounts of liquid) and are dispose. The cleaner and light density liquid mud up go through a vortex in the center of the hydrocyclone, exits through piping at the top of the hydrocyclone and is then flow to the mud tanks and the next mud-cleaning device, usually a desilter. Different size desander and desilter cones are functionally same, with the size of the cone determining the size of debris the device removes from the mud system.

During the operation of the drilling, the body of hydrocyclone is desander and desilter.  The size of the bore for desander is 100 mm and more and use filter 44-74 micron and above of the sand.  The size of the bore for desilter is less than 100mm for filter the 15 micron above.  Desander is use mainly on second steps of drilling fluid purification.  Desilter is use mainly on third step of drilling fluid purification.

Hydrocyclone is use for purification of the drilling fluid to ensure the performance in purification.  As part of the purification of the fluid use other machinery like shale shaker with filter screen and decanter centrifuge operate with high centrifugal force, all comes together with result  the removal of solid in drilling fluid within 2 micron.

Regarding to solids control system equipment, one may firstly realize shale shakers, desander and desilter, the decanter centrifuges and mud cleaner. But nobody could disregard the mud gun that is small equipment not small effect equipment.

GN Solids Control has much experience in designing and producing solids control system and equipment. Including the solids control system, I will introduce the essential function of the mud gun in the following paragraph.

What is the mud gun utilized for?

1, mud gun can be used to cooperate with the mud agitator to keep the drilling mud from settling. The mud agitator is installed in middle of the tank, and corresponding mud gun is near that, for caring concerning the tank corners.

2. for delivering drilling mud in one tank to the another. Obviously, the mud gun can’t accomplish this goal simply by itself, also it need assistance in the mud gun pipeline.

What does mud gun pipeline seem like?

A mud gun pipeline is really a 2 inch or 3 inch cubic pipe installed through the top frame of mud tanks. It covers nearly each tank from the system, aside from the shaker tank. Since the drilling mud in shaker tank isn’t active mud, which cannot be used directly in further drilling. However the drilling mud in other tanks, like active tank underneath the centrifuge, most occasions it may be employed for mud pumps. Or mud kept in storage tank.

Since the mud gun itself doesn’t have energy they are driving the mud, the mud gun line actually is associated with the blending pumps. Once the user have to transfer mud via mud gun pipeline, it always shut lower the bond between your mixing hopper and it is centrifugal pumps, then your pumps can be used to suck mud to mud gun line. By closing some tank’s mud gun lines, drilling mud is moved to destination tank via mud guns.

GN Solids Control is professional in solids control systems, if you have any problem about treating the drilling mud, GN will be the best choice.

It’s more frequently learned about dewatering unit in drilling industry but the majority of the persons working in this industry are not so acquainted with the dewatering unit. In the following paragraphs, I will provide a simple introduction on which is dewatering unit and also the application.

Dewatering unit we are also able to name it as ultra fine solids removing system. It always includes the fine solids separation system and polymer mixing system.

What’s the composition from the dewatering unit?

1. Feeding System

GN’s dewatering system has 2 screw pumps utilized for moving the flocculation and also the slurry towards the decanter centrifuge. The harmful chemicals and also the slurry meet in the feeding pipe from the decanter centrifuge and the flocs also created here. Then your slurry with large size flocs will get in to the centrifuge together there for separation.

2. Automatic polymer mixing system.

GN dewatering unit automatic polymer mixing product is 2 tanks system. It’s outfitted with medical feeding system, water injection system, mixing system and delivery system, electrical control system and gauge system. This APM system has 2 screw conveyors, the first is accustomed to transfer the powder medications towards the hopper around the mixing tank, and yet another screw conveyor is situated underneath the hopper to provide the powder in to the pre-mixing tank.

3. GNLW553-VFD dewatering centrifuge for separation

GN dewatering unit choose GNLW553 various frequency drive model serve as the separation centrifuge. The control panel was created as four various frequency drive for that centrifuge primary motor, back motor and 2 feeding pumps for slurry and medicals. Following the separation from the centrifuge, the big size flocs could be removed out, then your ultra fine solids is separated out.

The majority of the large capacity drilling project needs one set drilling liquids recycling system. As the drilling mud system is considered high configuration system and economic configuration model. Our prime configuration mud product is continually equipped for that oil drilling rig. This kind mud system consists all of the solids control equipment like shale shaker, desander, desilter, decanter centrifuge and vacuum degasser. For many deep oil wells drilling, the mud system is composed of numerous mud tanks for active mud storage. The economical configuration mud product is always employed for an oil well drilling, workover rig project, piling project and horizontal directional drilling project.

Workover rig mud product is little simpler within the solids control equipment configuration because the mud system sometimes only retain the shale shaker for just one stage solids control. The workover rig there is no need the drilling mud to become treated very clean. Additionally, it includes a mud mixing system that can be utilized to re-compose the drilling mud.

Based on the flow rate from the directional drilling rig, the HDD mud product is frequently split into different model. For example GN’s model 150GPM, 350GPM, 500GPM, 800GPM, 1000GPM and 1500GPM. The HDD contractor would always not utilize the decanter centrifuge in the system because the drilling fluid’s request is not such high around the cleanness. However, many clients has high request, they’ll also place the decanter centrifuge in the mud system.

The piling product is the easiest desanding unit there are just one tank and one set high capacity desander. GN solids control can supply the piling system of D50 and D100 according to the treating capacity. Always the piling product is no mud mixing system, the solids are taken away by the vibration screen, and also the liquids get lower towards the tank and also the pumped to the rig.

According to customer’s needs, all equipment shipped from GN factory could be first of all studying the commissioning process before the machine working. Sometimes, for that standard and individual equipment like shale shaker and mud cleaner or mud agitators, the trial test is going to be relative simple, therefore the customer could do on their own. The commissioning from the complete mud system, in order to some clients who don’t know how to operate solids control equipment, they might need GN dispatch engineer for their job site from the first time commissioning.

Before manufacturing the mud system, GN always asks the client to showcase their job site location and expected layout plan. Thus GN’s engineer would design the mud system according to the website area and layout. In the end the gear and hooking up parts shipped to site, the client could assemble the gear extremely fast according to design around the drawing.

Just like proven in below message, the mud cleaner unit is situated between 2 unit shale shakers. This isn’t an ordinary layout for drilling liquids recycling system. After fully consideration around the narrow part of the job site and convenience on hooking up the pipeline, GN’s engineering team suggested a strategy to place the cyclone unit between your shakers, the mud out of the well could be given individually into 2 unit shakers, after that it will pump towards the cyclone unit for more treatment.

GN’s shaker deck is locked throughout transportation, prior to the trial running, the operator need fixed the shale shaker on the top from the mud tank and unlock the deck. The vibration motor is originating from famous label Martin with explosion proof standard for thought on safety.

Simple structure is among the options that come with the GN’s shale shaker; the consumer can certainly master how you can operate it and perform the commissioning themselves. Concerning the control panel, GN provides electric diagram, the operator can begin and switch from the shale shaker without an excessive amount of electrical understanding.
