Recently GN solids control shipped one batch of the shale shaker, decanter centrifuges to Russia drilling rig. The client will produce the mud tank locally to save freight cost, import tax and save delivery time, and buy the major equipments from GN.

Shale shaker is the most important equipments and first phase cleaning equipment for oil drilling rig solids control equipments, the lastest model shale shaker is F version shale shaker. Compared with the previous version shale shaker, the features of F version shale shaker is as below:
1) Composite material frame shaker screen for longer working life, the screen mesh over API 60 all use 3 layers wire mesh for reliable quality.

2) The screen deck bottom is made of stainless steel 304 material for better Corrosion resistant, with 3 layers costing and painting with Japan Kansai brand or US PPG brand Marine anticorrosive painting.
3) Italy Oil brand vibrator or Itavibras or US Martin brand vibrator to meet client’s different explosion proof requirement。

Decanter centrifuge with 3200rpm high speed to separate the low gravity solids, after long period drilling, more and more fine solids will accumulate in the drilling fluids, which can not be separated by desilter cone and low speed decanter centrifuge, then the recovered the drilling fluids can not be reused to prepare for new drilling fluids, the user need the high speed centrifuge to reduce the solids content and separate the fine solids out. Normally they will use the low speed centrifuge before the high speed centrifuge for barite recovery, or they can use a VFD decanter centrifuge to use for both barite recovery and LGS if there is not enough space to install 2 centrifuges.
If you need major shale shaker, mud cleaner, decanter centrifuge for oil drilling rig, pls contact with GN solids control.

Solids control equipments are shipped to Uzbekistan cold weather

BY gnadmin 29 November 2018 decanter centrifuge, drilling waste management, mud cleaner, shaker screen, Shale Shaker, solids control

Recently GN solids control shipped several units of solids control equipments for Uzbekistan for cold weather, these equipments are special for low temperature operation to -50℃.We have provided such low temperature solids control equipments to Russia area oil & gas drilling rigs before, including the containerized drilling waste management system. The technical configuration of low temperature containerized drilling waste management system is as below:

The feeding system to the drilling waste management system is through screw conveyor, it is transferred to the open top of the vertical cuttings dryer. One unit of vertical cuttings dryer installed on the mud tank, the discharged solids are dropped down to a continuously working screw conveyor to ship it out from the opening of the standard 40ft container. The fluids dropped to the mud tank and the screw pump will transfer it to the VFD decanter centrifuge ,which is also installed on a short mud tank, the fluids are treated by the VFD decanter centrifuge again and the solids discharged will be also transferred out by the screw conveyor for disposal. Another screw pump is installed on the vertical cuttings dryer mud tank as the flushing pump, once the working is finished, it is necessary to flush it or when the screen basket is blocking, it is necessary to flush with the flushing pump.

All the equipments are installed inside the 40ft container to keep the system warm in cold weather below minus zero degree, to prevent it from getting frozen. The 40ft container is with windows and doors for convenient operation, all the walls attached with the Insulation for better warm.

1500HP Drilling Rig Solids Control System to India

BY gnadmin 21 November 2018 drilling mud system, shaker screen, Shale Shaker, solids control

1500 HP drilling rig solids control system is ready for shipment to India, this is not a complete solids control system, but the essential mud tank for the solids control system- shaker tank, the technical specification is as below:

1) 3 units of GNZS703F-SHBF shale shaker with 3pcs screens with composite material frame shaker screens
2) 1 unit of GNZJ703F-S2S12NF mud cleaner which is desander cone, desilter cone and under flow shale shaker which is the same model with shale shaker

3) 1 unit of horizontal vacuum degasser GNZCQ360A
4) 1 set of mud tank equipped the equipments mentioned above, the mud tank dimension is 14000 x2800x 2500mm, including the trip tank, sand trap, desander compartment, desilter compartment, degasser compartment
5) 2 units of centrifugal pump as feeding pump of desander and desilter
6) 1 unit of centrifugal pump as trip pump
7) 1 unit of mud gas separator GNZYQ1000A
8) 1 set of carbon steel material shed for sun proof, rain proof

The one mud tank design is to meet the client’s requirement to replace the old shaker tank, and the remained part of the existing solids control system is still in usage. All the necessary connection dimensions can fit with each other through good communication with clients. The explosion proof electric control system is equipped to control all the electric motors in the system and the big motors are controlled in the MCC at client’s rig site.

Workover Rig solids control system shipped to Australia

BY gnadmin 1 September 2018 drilling mud system, Shale Shaker, solids control

This week GN shipped one set of workover rig solids control system to Australia. The configuration is as below:
1) Shaker tank with 2 units of shale shaker to clean the drilling mud

2) Mixing tank with mixing hopper, 2 units of centrifugal pump to prepare for new drilling fluids
3) Mud agitator, mud gun, pipelines, valves all equipped with both mud tanks
The difference for this solids control system between normal solids control system:
1) All the electric control system include cables, glands, electric components, and the design should be comply with Australia explosion proof standard
2) The lifting pad, walkway, handrail, the distance between adjacent components, etc should be comply with Australia safety regulations
3) The welding and painting standard is also very strict in Australia, the tank top surface is fixed with high strength glass fiber reinforced plastics.

4) The clean gate is with high position gate valve type clean gate for convenient operation and cleaning of the accumulated solids
GN design and manufacture the workover rig solid control system as per the client’s special requirement and Australia standard. This is not the first unit of solids control system shipped to Australia, we had sold over 30 units of mud recycling system for HDD industry.

Two sets of large bowl decanter centrifuge and two containerized chemical dosing systems shipped to Singaport

BY gnadmin 18 November 2017 decanter centrifuge, drilling mud system, drilling waste management, solids control

In recent weeks, GN Solids Control just finished its production for a new project in the tunnel bored drilling industry, the order includes two large bowl decanter centrifuge and two containerized chemical dosing system. Successfully delivered this system to the customer representing GN’s great manufacturing capability and strong delivery capability.

GN Solids Control is a integrated company specialized in manufacturing the solid control equipment and spare parts, including but not limited to shale shaker, decanter centrifuge, cutting dryer, etc. This two new large bowl decanter centrifuge have the bowl size of 22 inches, and can process large volume of drilling mud and make it meeting the standard of disposal and recycle. This large bowl decanter centrifuge inherited the same great features from its predecessor 363 which is a very popular, mature and reliable product during all GN’s product line. The bowl material is made of 2205 stainless steel which is very tough and reliable, the screw conveyor surface is covered with tungsten carbide tiles which is easy for replacement and very easy for maintenance. The solid and liquid discharge port is also made with the tungsten carbide inserts, which has very good longevity. The bearing is provided by world famous brand SKF. All in all, this is a very cost effective but very good quality product. The containerized chemical dosing system is a great value and supplement to the decanter centrifuge, if the customer want to separate smaller solids, as the decanter centrifuge can only separate the solid size from 5-20 microns, when using the chemical dosing system, the solid separation size could reach up to almost zero. GN believe the customer will like it after using it.
