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.

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.

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.
Features of the solids control system:

As the most professional solids control and drilling waste management equipments manufacturer in China, we design and produce shale shaker, mud cleaner, decanter centrifuge, mud agitator, mud gun, mud gas separator, vacuum degasser, centrifugal degasser, jet mud mixer, shaker screens, various pumps, as centrifugal pump, submersible slurry pump, progressive cavity pump, shear pump, and drilling waste management equipments like vertical cuttings dryer, VFD decanter centrifuge, vacuum pump, screw conveyor and oil sludge separation system, etc. shaker screens are one of our major products, we can produce OEM shaker screens for our own shale shaker and replacement shaker screens for world famous brand shale shaker, like Mongoose, Derrick FLC513, 514, 503, 504, Derrick 48-30, Derrick 600, hyperpool, Brandt Cobra/ Venom, VSM300. If you need high quality, long working life, good performance with reasonable price shaker screens, pls contact with GN solids control.
Advantages of GN shaker screens:

This week GN solids control shipped 2 sets of HDD mud recycling & mixing system to India client for their HDD projects. This is not the first order from the HDD contractor, they bought the 350gpm mud recycling system and 500 gpm mud recycling system several years ago for their Vermeer rig. The technical configuration is as below:


One mud tank 9000x2300x2150mm which is customized design size to meet their storage capacity requirement. For compact design and better mud cleaning performance, we installed the double deck shale shaker with desilter cones to meet the client’s capacity requirement. A centrifugal pump as feeding pump of the desilter cone, one centrifugal pump as mixing pump for the venturi hopper. The mud agitator and mud gun installed on the mud tank for agitating the drilling mud and prevent the solids from silting. An extra submersible slurry pump is equipped as the feeding pump of the mud recycling system from the mud pit.
Features of the 2 sets of mud recycling system:
1) Compact design with the biggest storage capacity as per the client’s requirement
2) Container loading size for convenient transportation and cheaper sea freight cost
3) Mechanical seal centrifugal pump, the impeller and pump casing material is made from hard ductile iron alloy, increased abrasion resistant capability.


4) Double deck shale shaker with desilter cone for 2 phase cleaning and increase the reating capacity.
5) Pretensioned shaker screens with composite material frame for longer working life and better separation performance.
6) Explosion proof electric control system for better rain proof, sun proof and dust proof.
