GN Solids Control solids liquid separation decanter centrifuge have been working for oil drilling many years. The stable working performance and reliable life time win good reputation for GN Solids Control. And now we just published three phase  centrifuge for solids, water and oil three phase separation.

Except for decanter centrifuge and three phase centrifuge, GN main market is still in drilling waste management and solids control equipment.

GN drilling waste management equipment including: vertical cuttings dryer, waste centrifuge, solidification unit, fixation unit, thermal desorption unit, etc. Drilling Waste management equipment is used to treat the solids mixture discharged from shaker, recover valuable drilling fluids for reuse and reduce the waste need to be treated in following stages.

For water based mud, client normal choose High G drying shaker, decanter centrifuge and solidification unit. After treatment of solidification unit, the solids can be buried in cement ponds as final step. For oil based mud, client need to use vertical cuttings dryer, decanter centrifuge, thermal desorption unit. Thermal desorption unit can get cuttings solids with oil below 0.3%, this standard can meet the requirement of most country’s government protection policy. Compared with water based mud, OBM cuttings treatment cost is much higher both in equipment expense and operation cost.

GN Solids Control equipment including: shale shaker, mud cleaner, shaker screens, desander, desilter, decanter centrifuges, mud agitator, centrifugal pump, screw pump, mud tanks etc. GN Solids Control mud system can form a close loop mud circulation with drilling rig and mud pumps. After the mud ready for drilling, the mud pump will suck from the mud system and feeding for drilling rig. The mud from drilling rig flowline will go back to mud tank system for cleaning, adjusting and go back to mud pump. The mud tank system generally include four stage mud treatment and will remove particles in different size by different stage, shale shaker stage, desander stage, desilter stage and decanter centrifuge stage. Two phase separation centrifuge is mostly used in solids control system, very few clients choose three phase centrifuge.

GN Solids Control decanter centrifuge is designed for solids control in oil and gas drilling field. With the mature product, GN is spreading the business scope to more other fields, including Centrifuge for HDD drilling, centrifuge for diamond drilling, centrifuge for waste water treatment, centrifuge for food industry etc.

GN Solids Control have almost 10 years experience in solids control and drilling waste management equipment manufacturing. As China most experienced company, GN put large percent power on the optimization of decanter centrifuge. Without doubt, Decanter Centrifuge is the most advanced equipment in solids control line, play key role for the total system working performance.

GN Solids Control has different stage for the development of decanter centrifuge. After these years hard work, GN Solids Decanter Centrifuge can show much higher working performance compared with other China brand centrifuges. GN have different model centrifuge for option:

9inch bowl small size decanter centrifuge GNLW223 for waste water treatment, this centrifuge can be used for diamond drilling, hall core drilling, mining etc, some small drilling rigs. Together with shaker, the centrifuge can be used to remove solids from waste water, and the clean water can be reused for the projects.

14inch bowl popular size decanter centrifuge for solids control and drilling waste management

This GNLW363CG decanter centrifuge is the most popular model, we can sell about 200sets each year to overseas market. It is mainly used for solids control, working after mud cleaner to remove the fine solids and reduce the mud weight.  Working together with flocculent unit, the centrifuge can remove much fine solids after coagulation and flocculation.

18inch bowl popular size decanter centrifuge with short bowl for barite recover, GNLW452 centrifuge is mainly used for barite recovery, for solids control.

18inch and 22inch bowl popular size decanter centrifuge with longer bowl for solids control and fast drilling mud treatment

If you are from oil drilling field, we recommend you GNLW363CG fixed speed decanter centrifuge or GNLW363CG-VFD variable speed decanter centrifuge for flexible use. This is also the most popular model centrifuge, we have stock in warehouse for fast delivery. We can also offer DNV certificate if the centrifuge will be used for offshore and need helicopter lifting transportation.

GN Solids Control has been working for solids control equipment for many years. With rich experience, GN can design good performance solids control equipment, with much proper production material and reasonable price. Recently, we export one batch of solids control equipment to Middle East clients.

1) Middle Speed Decanter Centrifuge

The client is local HDD contractor with some HDD drilling rigs. At the beginning of this year, they got one big project for gas pipelines from local government and they realize the necessary of one set middle speed decanter centrifuge to continue the work. After several rounds discussion, the client finally choose 18inch decanter centrifuge GNLW452C-VFD. This model centrifuge can have bowl speed from 0 to 1800RPM; treating capacity can reach to 60m3/h, equal to 260gpm. The centrifuge is equipped with one 45kw motor, total energy consumption is also lower than dual motor centrifuge.

GN Solids Control Decanter Centrifuge has good reputation in oil drilling solids control and waste management field. Even we have some send hand centrifuge; it can be sold to clients very soon. Second hand centrifuge price is much better than newly centrifuge, quality is not problem. We have one sets second hand centrifuge in USA warehouse, and when we were in Houston for OTC oil show, we meet some clients there and some clients show much interest in the second hand centrifuge. After the clients visited the second hand centrifuge in our Houston, USA, the clients is very satisfied with the work condition of the current centrifuge, and they arrange payment after that soon.

As China & USA leading supplier for solids control equipment and drilling waste management equipment, GN Solids Control just deliver large quantity of solids control equipment to Middle East, the clients have been in connection with GN Solids Control for over 5 years. Even the market is down, the client still buy some solids control equipment for the ongoing drilling operation. In this year, the clients bought some shale shakers, mud agitators, mud gun, centrifugal pumps etc.

GN Solids Control equipment can work for oil & gas drilling, HDD, CBM, Coalbed methane etc. The mud system or solids control equipment work to treat and recycle the drilling mud, which have lots of benefits for drilling bit.

GN Solids Control equipment can also work in mud plant, where lots of drilling waste mud comes into for treatment. Recently, we have one mud service client own a liquid mud plant. The client have some old brandt centrifuges for use and they need more centrifuges and shakers. The client know GN Solids from 2013 and have more and more understanding about GN Solids Control equipment in the past three years. In this year of May, the client release purchase order and payment for the decanter centrifuge, shale shaker and centrifuge feed pump, as well as some necessary spare parts.

1) Decanter centrifuge for liquid mud plant
The client choose variable speed centrifuge as flexible use option. GNLW363CG-VFD is the most popular centrifuge model for oil drilling market, as well as drilling waste management application. The centrifuge can reach to 3200RPM bowl speed; the differential speed can also be adjusted to get better working performance.
This is GN 14inch bowl centrifuge, we also have 9inch bowl centrifuge, 18inch bowl centrifuge, 22inch bowl centrifuge for option. 14inch bowl is the most popular and we have some units in stock for fast delivery.

GN Solids Control already ship 3 sets HDD drilling mud system to one client in Middle East in the past two years. The clients give repeat purchase order as they are satisfied with the GN compact mud cleaning system for HDD project. For overseas HDD market, very few clients need centrifuge because of the higher cost, as well as the technical operations. However, the client was faced with more critical situation in one HDD site and need one set middle speed centrifuge to remove the fine solids from the drilling mud, to ensure the recycle mud can be reused effectively.
