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.

Barite recovery centrifuge system available in Houston warehouse

GN solids control designed barite recovery decanter centrifuge product is welcomed to get ready checked in GN Houston warehouse at 6710 Wind fern road, Houston, Texas 77040.

The configuration of the barite recovery product is as below:

1 GN Hi-G dryer shaker GNZS594E-HB, we've 10 models of these shakers available there, it's a 4-panel pre-tensioned screens shakers with total screens area 2.73 square meters. The part from the shaker would be to separate the large solids and fewer the solids content before feeding towards the decanter centrifuge.

2 GN variable frequency drive decanter centrifuge for barite recovery

Each of GNLW452 and GNLW453VFD decanter centrifuge can be utilized as barite recovery, the most typical model and efficient strategy is GNLW452 decanter centrifuge, if you wish to alter the speed in line with the mud weight, you are able to alter the lever and belt, but it's not convenient to alter the lever, you need to steer clear of the centrifuge, anyway, it's the most economical way.

GNLW453VFD decanter centrifuge is variable frequency drive decanter centrifuge which has big volume and high speed, you are able to alter the speed through the PLC controlled VFD control panel if different mud weight.

Another option is to find 2 models centrifuge, GNLW452 for top gravity centrifuge, GNLW363VFD or GNLW453VFD centrifuge for low gravity centrifuge.

3 jet hopper system

4 catch mud tank

5 Necessary spares, like shaker screens

Also we offer the choices to place the shale shaker, 2 decanter centrifuges on a single mud tank slid, with 2 VFD control panel and jet mud mixer system.

Aside from barite recovery system, we design the entire system for dewatering centrifuge along with solids removal device. For more information relating to this project, please contact GN Solids America. We now have hi-G dryer shaker and VFD decanter centrifuge for test.

The designing of GN mud tank

GN Mud tanks are broadly utilized in solids control area, even though the functions might appear quite resembles to storage the muds or drilling wastes for various separation steps, many of these tanks play an important part in solids control system.

Today we’d like to share some info regarding how to design a GN mud tank roughly in a fast way.

To create a GN mud tank, we have to understand how our customer likely to transport to their region or even the ship approach to their country. Usually you will find different land transportation limits in a variety of nations, so these restrictions are the initial amounts we have to consult with our clients. But many of these restrictions should be inside a container.

Therefore the second factor has to consider the ocean transport way. Will the solids tools be placed into container? Will the devices be made to exactly the same size according to the container? Or will the devices be shipped in large quantities? Rely on different shipping techniques; the tank could be designed into different limited dimensions.

When the tank is defined right into a container, the biggest width is 2250mm (including sand cleaning doorways and lifting lugs) When the tank was created like a standard container, compared to biggest width is 2588mm Or maybe the tank is a large capacity tank, the biggest width is 2950mm.

For these tanks, we usually designed all of them with integer number, from 4m to 12m. Its better the space isn't beyond 13.5 m. When the tank (length is 6m) is created into 20 ft. container, the space ought to be 6058mm while for tank (length is 12m) is converted into a 40 ft. container, the space is 12192mm. Skid-mounted tanks should plus 250mm both in finishes from the tank (that is 500mm as a whole), the ultimate length is by using .5m.

See Dried Drill Cuttings in Water-based Mud after Handled by GN Vertical Cutting Dryer

Recently, after i cited one of my clients on GNLW decanter centrifuge, he explained he also requires a drying solution of mud treatment. Certainly, GN solids control can offer a total solution. Last year, GN has shipped several drilling waste cuttings management system, the first is for an African customer, the other is for Cyprus customer. And lately, GN offered 4 models of drilling waste cuttings management to Russia for Baker Hughes.

Regarding to drying solution, there tend to be two ways. The first is applying High G force linear motion shale shaker that is usually utilized for water-based drilling mud for which is much harder to manufacture, the second is vertical cutting dryer that is used for oil-based mud. As the problem for dry drilling waste water-based mud with a high G pressure linear motion shale shaker would be that the shale shaker can't provide the expected drying effect.

While, GN Solids Control has shown in CNPC job site that GN second generation vertical cutting dryer could handle water-based drilling waste, and provide expected results. It really is break-through news, meaning companies may use GN vertical cutting dryer to exchange high G pressure shale shaker to deal with water-based drilling waste to obtain more satisfying results.

After treated by GN vertical cutting dryer, solids discharge in the bottom opening is proven as with the next pictures. The drilling waste liquid can be dealt by GN high-speed decanter centrifuge. Next, the liquid could be used again within the drilling mud system. This vertical cutting system reduces most of cost for drilling companies to mixing drilling mud, and save lots of money to dispose the drilling cuttings waste.
