Recently GN solids control shipped one batch of solids control equipments to Uzbekistan for low temperature cold weather. The solids control equipments including shale shaker, mud cleaner, decanter centrifuge, vacuum degasser, etc, the environmental temperature is below -50℃.We have much experience to provide low temperature solids control equipments for cold weather, we had sold many sets of drilling waste management systems equipped inside the 40ft container to keep the equipments and drilling waste warm and prevent them from frozen and stop working.

As the most professional solids control equipments manufacturer in China, we provide the complete line solids control equipments for oil & gas drilling rig, the main equipments as shale shaker, mud cleaner( also as combo unit), decanter centrifuge, vacuum degasser, centrifugal degasser, mud gas separator, mud agitator, mud gun, mud hopper, centrifugal pump, shaker screens, etc. According to client’s different requirement, we will provide different explosion proof standard vibration motor, electric motor and control panel to suit for different weather, different kinds of drilling fluids.

We have linear motion shale shaker and balanced elliptical motion shale shaker for option, also we have dual motion shale shaker to meet client’s requirement. Normally linear motion shale shaker is enough for drilling, we use Italy Oil brand vibration motor or US Martin brand vibration motor or Italy Itavibras brand vibration motor for different projects. The composite material shaker screens are installed on the shale shaker freely, the shaker screen size is interchangeable with world famous brand shale shaker, GN solids control produced composite material shaker screen is with longer working life, better separation performance, longer storage life, larger effective screen area, better quality then traditional steel frame shaker screens.

Recently one set of 1500HP Drilling Rig Solids Control System Package is almost finished production for India client, this is the repeat order from the same client for customized design.
The features of the shaker tank package:

1) 3 phase cleaning of drilling fluids, shale shaker is the first phase cleaning and the most important cleaning of the drilling fluids, the better separation performance of the shale shaker, the better cleaning of the whole solids control system, if the shale shaker did not work well, the coarse solids will drop into the sand trap and it can not control the solids content effectively, it will influence the cleaning performance of the next step cleaning desander cone and desilter cone, the higher solids content will damage the desander cone and desilter cone very easily and quickly. Also the centrifugal pump will be also easily damaged for the same reason. Desander cone is the second phase cleaning, desilter cone is the third phase cleaning, the cut point is 20 microns. The decanter centrifuge system is an additional requirement as the 4th phase cleaning.

We installed the durable composite material shaker screens for the better separation performance, the effective screen area is 20% larger than steel frame shaker screens, the storage period is up to 5 years, the working life is much more longer than traditional steel frame shaker screens.
2) Compact design, convenient transportation for the whole package

This week one unit of containerized 15 m3/h oil sludge separation system to Europe client.
The configuration consists of 5 modulars:

1) Pre- mixing tank: the pre mixing tank is necessary, it will influence the result of the equipments next, like shale shaker tank, decanter centrifuge tank, disc centrifuge tank.
2) Shaker tank: the shale shaker with mud agitator installed on top of the mud tank, heating lines around the tank to increase the oil sludge flowability and increase the decanter centrifuge separation performance.

3) 2 phase separation tank : the 22 inch decanter centrifuge installed on top of the tank, the screw pump installed on the same skid, and the screw conveyor collect the solids from the solids discharge port of the decanter centrifuge and transfer outside the container.

4) 3 phase separation skid ：the disc centrifuge installed on the skid, the fluids discharged from the centrifuge fluids port flow to disc centrifuge, the clean oil and water will be pumped to separate oil tank and water tank.
5) Chemical dosing system: the chemical dosing system with 3 mixing tank chemical dosing system, and the coagulation system, each tank with chemical dosing pumps.
The oil sludge separation system is used in cold area, so all of the equipments are installed inside the 40ft container to keep it warm. We also consider the operation convenience for the user.
This is the repeat order from the same client, they bought one unit of 1 m3/h oil sludge separation system several month ago, and satisfied with the result.
Except for oil sludge separation system, GN solids control also provide good quality solids control system, drilling waste management system, we will send the question list to the client to know the project information firstly, then we will design customized system for our clients.

2 sets of oil sludge separation system are finished production in GN solds control, one system with grey silver color is 2 m3/h oil sludge treatment system , the other one is 15 m3/h oil sludge treatment system, which will be released next week.

The 2 m3/h oil sludge treatment system is a trial order for the client, if it works well, the client will repeat order for a bigger one, GN standard and customized oil sludge separation system has been proved the performance.

The technical configuration is as below:
1) Pre-mixing tank
Premixing tank is the necessary part of the oil sludge separation system, the sludge vacuum pump transfer the oil sludge from the waste pit to pre mixing tank for heating, agitating, chemical jetting, without proper premixing, the fluids flowrability will be increased, the separation result will be better.

2) Classification modular, the oil sludge from pre mixing tank will be transferred to V tank bottom which with screw conveyor on the bottom, after classification, the top layer will flow to disc centrifuge, the bottom layer will be washed, chemical jetting and transferred to solids control manular.

3) Solids control modular: it consists of shale shaker and 2 phase decanter centrifuge for liquid solids separation. The clean fluids separated from 2 phase decanter centrifuge will also flow to disc centrifuge modular. Both of the tanks with heating line around for heating the oil sludge and increase the separation efficiency.

4) 3 phase separation skid: this is a back up skid, including gravity type oil water separator, once the disc centrifuge failed to work or during maintenance, the 3 phase separation skid will be work as back up.
GN solids control can design and produce customized oil sludge separation system as per client’s different requirement. Pls contact with GN team freely.

As a professional drilling fluids shale shaker manufacturer in China, GN solids control developed offshore ViST vacuum shale shaker and shipped to offshore project this week.

Why use GN ViST vacuum shale shaker?
The user already installed solids control system at site, why they should use GN ViST vacuum shale shaker? GN ViST vacuum shale shaker is GN shale shaker with a vacuum suction hopper installed under the last shaker screen. It has a combination function of solids control shale shaker and high G drying shaker, and save the space to install the high G drying shaker, especially for the offshore drilling rig when there is no enough room to install drilling waste management equipments, The ViST vacuum unit solved the problem.

By using GN ViST vacuum unit, the drilling fluids recycling efficiency will be increased by 30~ 50%, it reduced a lot the discharged drilling cuttings, then reduce the cost to transport, treat and disposal the drilling waste. It reduce the hazardous drilling waste influence to environment, and do not waste electricity power at site, it can use the same air compressor with rig.
