This is special designed for our customer’s requirement, we have standard triple shale shaker and mud cleaner as GNZS594F-SHBF and GNZJ594F-3S16N if no special requirement.

Recently we have one batch of composite material frame shaker screens ready for shipment for a international drilling companies. We packed 18pcs screens at each plywood pallet, each piece screens packed by GN standard design paper box, we can also provide neutral paper box as per client’s requirement.


GN shaker screens are produced as API RP13C standard and have test report from API authorized agent in America. We can produce shaker screens from API 20 to API 325, the mesh size over API 60 all adopted 3 layers stainless steel wire mesh for better strength. The composite material frame lasts longer working life than steel frame screens, and larger effective screen area for better separation performance.


Shale shaker is the first phased cleaning equipment at solids control system, shaker screens are consumption parts of shale shaker, the user always make proper stocks for the shaker screens for convenient operation, the composite material frame screens can be storaged up to 5 years without getting rust. Based on different drilling fluids, the shaker screens working life will be different. The composite material shaker screens are repairable with plastic plug. The 3 layers 4-sides pretensioned wire mesh before heat pressing will provide enough strength. We can make customized color for the composite material frame as per client’s requirement. We adopted wedge as shaker screen locking system, the user can replace the shaker screens easily and fastly, the user can use the ratchet wrench to lock and release the wedge and take the shaker screens easily. The shaker deck angle can be adjusted by both sides simultaneously from -1ºto +5º.
When install the desander and desilter frame on top of shale shaker, the 3 in 1 mud cleaner as the second phase cleaning and the third phase cleaning equipment. The desander cone and desilter cone are 100% PU wear-resistant material.

Recently we finished production of one set of solids control system to India, including shaker tank and decanter centrifuge tank system. This is a 5 phase separation mud tank system for 1500HP oil drilling rig. The working principal is as below:


1) 3 units of shale shaker as the first phase cleaning to separate the big solids bigger than 100 microns from the drilling fluids, it can be used for both water based mud and oil based mud or synthetic oil based mud. The shaker screen installed on the shale shaker is composite material frame shaker screens comply with API RP13C.


The possem belly is installed behind the 3 units of shale shaker as drilling fluids distribution box and collect the drilling fluids from the mud gas separator or from the elevated manifold directly.
2) desander cone is the second phase cleaning to separate the cut point below 45 microns. The fluids with solids below 45 microns will drop into the mud tank compartment. The 2# centrifugal pump suck the drilling fluids from this compartment and feed to 4 inch desilter cone.
3) desilter cone is the third phase cleaning to separate the cut point below 25 microns the fluids below 25 microns will drop into the desilter compartment and the submersible slurry pump will suck the mud from this compartment and feed to GNLW452C decanter centrifuge.


4) middle speed decanter centrifuge is the fourth phase cleaning to separate the cut point 5~7 microns for barite recovery.
5) high speed decanter centrifuge is the fifth phase cleaning to separate the solids 2~5 microns for high gravity solids, especially when the drilling fluids has been reused for several years, the fine solids is accumulated a lot and it can not be reused again, then the high speed decanter centrifuge is required to lower the solids content.

This week GN solids control shipped one unit of HDD mud recycling system and dewatering unit to Sinopec project. HDD is one of our major applications, GN equipments 4 major applications including oil & gas industry solids control system and drilling waste management system and oil sludge separation system, HDD & CBM industry mud recycling system, Piling & TBM desander unit, Industry waste water treatment.


The technical configuration is as below:
1) 3 phase cleaning mud recycling system mud tank, with containerized frame for convenient transportation, the user can put the mud tank and the frame with equipments on the trailer and move to another site from one site.
2) 1 unit of GNZS703F shale shaker as the first phase cleaning equipment, equipped with 3pcs of durable composite material shaker screens with customized API mesh screen. We produce OEM composite material shaker screens from API 20 to API 325 as per client’s requirement.


3) 1 unit of GNZJ703F-1S8N mud cleaner, with under flow shaker, desander cone and desilter cone combination unit. Equipped with 2 units of centrifugal pumps as feeding pump of desilter cone and desander cone.
When the drilling fluids temperature is over 70 degree, we will use special material hydrocyclones for longer working life.
4) Dewatering system with same dimension mud tank
5) Decanter centrifuge GNLW363C-VFD is the 4th stage cleaning to separate fine solids smaller than 15 microns. After several years working, more and more fine solids are accumulated in the tank bottom, these fine solids can not be separated by the desilter cone, then high speed decanter centrifuge is required to clean the drilling fluids, otherwise it can not be reused for drilling again.

From early 2015 till now, the crude oil price is like the roller coaster, falling dramatically and then up a little bit then down again. It’s testing everybody’s heart durability. Recently the oil price seems a little bit stable than before. The West Texas Intermediate oil price fluctuate between $45 to $50. Well, this seem better than the price earlier this year which dropped below $30. But it still far below the price for the oil company can make money. Everybody is struggling, nobody wants to give up and if we can’t make money, we need to try all of our best to figure out how to save money. GN Solids Control, as the leading company in the solid control business, can help you save money and survive in the tough time.


As an important part of the drilling system, solid control system plays crucial role in the whole process. If managed well, the solid control system can save you a lot of money in terms of the mud cost, the consumables, and equipment procurement cost. GN’s equipment from shale shaker, desander, desilter, mud cleaner, decanter centrifuge, to agitator, centrifugal pump, mud gun and various of tanks, are all cost effective and good value for money. There are several advantages GN can reduce the equipment price. Now GN has realized the large scale manufacturing for the equipment and consumables like screens. This can help reducing the procurement cost, labor cost and be more efficient. If the quantity is large, this will also reduce the transportation cost.
