It is a common knowledge that in the solids control system for a drilling rig, no matter for the land rigs or for the offshores, the shale shaker plays the most important role for separating out the solids waste from the mud recycling unit, and it is also the shale shaker which waste the most of the liquid on the cuttings discharged from the shaker. That’s why, in many countries, there is a must to equip another drilling cuttings treatment system alongside the rig.
A drilling cuttings waste management system is used for further separation of the drilling waste discharged from the shale shaker and mud cleaner, most of which are from the shakers. For one thing, the drilling cuttings waste management system helps to dry the cuttings for later transportation, on the other hand, it increased the drilling liquid amount to be recycled. Both are saving money. In case of OBM mud, the operators always need a vertical cuttings dryer and a high speed decanter centrifuge, while for WBM mud, operators always use a high G drying shaker and a decanter centrifuge.
In some cases, the ViST Shaker screen device could replace the drilling cuttings waste management system, or at least to some degree, reduced the work for the cuttings separation works. Generally speaking, the ViST shaker screen device has following advantages:

ViST shaker device

1. It is suitable for both WBM and OBM mud in a solids control system.
2. It is a compact structure, and only use an air compressor as power source, and one set of ViST could serve up to 3 sets of shale shakers.
3. It is designed to be suitable for different shaker models.
4. In practice, it helps to save the liquid amount by 30% to 50%.
Now for GNZS703 and GNZS594 series shale shakers, there are ViST device for option.

Recently, GN just finished another set of solids control system to Australia, which is going to be used for oil and gas industry and now the system is at sea for sailing to Australia. Seldom solids control manufacturers could reach such a high standard of Australia, which are even higher than the USA and Europe. But this system is not the first one. In recent years, GN has provided to Australia 3 sets of oil and gas solids control systems, and more than 30 sets of mud systems for HDD projects.
Besides the normal standards for the oil and gas industries, the Australian market has its specially high standards:

1. For electrical components, including the motors, cables, glands and control panels, all have to meet both IECEX standards and Australia standards.

2. Walkways and guardrails must reach very specific standards, like the max and min distance of gaps. Lifting pads and lifting eyes all have to meet safety standards, and marked with SWL.

3. Walkways and stairs are made of high duty fiber glass, instead of gratings or checkered plates.

4. Higher standards for welding and painting.

Australian companies are quite strict when choosing the supplier and inspecting the equipment. During fabrication and before delivery, there are top management and third party engineers coming to GN Solids Control for checking their orders. They are quite satisfied with GN’s factory management and designing ability of GN engineers.

In fact, GN has more than 10 years of experiences in this solids control and waste management industry and GN was the first API certified manufacturer in China for oil and gas solids control equipment. GN’s products, like the shale shakers, mud cleaners, decanter centrifuges, vertical cuttings dryers, mud agitators and centrifugal pumps are exported to more than 70 countries of the 5 continents in the world. And also GN shaker Screens.

The augers are also called the screw conveyors, they are used in GN drilling cuttings waste management system as a matching equipment alongside with vertical cuttings dryers and decanter centrifuges.
In some rig sites, it is requested by the law that for each drilling rig, there must be a set of drilling cuttings waste management system, and totally in the rig site, there should be at least 2 augers: first one is below the discharge chutes of shale shakers, desander cones and desilter cones, that is used to collect the cuttings. Second one is used as a sloping angle to transfer the cuttings from the first one to the vertical cuttings dryer. In a word, the augers could be positioned sloping or horizontal for different destinations. In a word, GNSC screw conveyors could work in a group or singly, and they could be used for mixing, allocating, dewatering, discharging and etc.

gn augers

As an essential part of a waste management system, in order to well match the other equipment and easy for transportation and locating, all GN screw conveyor models are designed in same length sections, each of 12 ft. And they are of different diameters for providing different transferring capacities. There are 10 inch diameters, 12 inch diameters, 14 inch diameters and 16 inch diameters. In this condition, most of spare parts are interchangeable, which reduced the spare parts cost and enhanced the convenience for the end users. GNSC series screw conveyors are using the wear proof material for a obviously longer service life than its peers’.
GNSC series screw conveyors are not only used in the drilling cuttings waste management systems, they are also quite widely used in construction, chemical, power plants, coal mining and other industries. In some customized conditions, GN could also add the insolation layer to the augers to keep the temperature at a certain range.

In the past CIPPE 2018 international oil exhibition which was held in Beijing last week, GN brought out some new products including a compact oily sludge separation unit. And this newly built oily sludge separation unit attracted many visitors.

GN AT CIPPE 2018

GN AT CIPPE 2018

GN Solids Control, ever since its establishment, always set its goal as China Intelligence. Each year, GN Solids Control’s R&D team make into reality some new designs and those are always proven to be practical and efficient. For example, in last year’s CIPPE, GN took to exhibition a 30 inch bowl decanter centrifuge and a fully hydraulic decanter centrifuge, and in this year, the 30 inch decanter centrifuge was soon put into use in a TBM project and was proved to be a success and good comments from client. This year, the new equipment GN brought to CIPPE 2018 including following:
1. Mini oily sludge separation system, including pre-heating step, chemical dosing step, shaker for separating the large particles, decanter centrifuge for separating our the fine particles and a three phase centrifuge for further separating the oil, water and solids. After those treatments, the OOC could reach 2%, solids and water in oil is less than 3% and oil in water is between 50-100 ppm. By using the pipelines and valves, the chemical could be dosed both before and after shaker, and the light material before entering the decanter centrifuge could by pass the centrifuge to reduce the burden of centrifuge.
2. Vacuum pump. Vacuum pump is not exactly a new product of the year, cause last year, GN already put it into use. But this year, GN improved it and gave it to jobsite for test. It is excellent. It could transfer even solids, with a small character to flow. That’s why it is called a solids pump with wide applications.
3. GN full range of shaker screens for GN own brand shakers and other famous brands. For the frame screens, GN already upgraded them into composite material frame ones, for the hook ones, GN is upgrading them now.
4. GN core products including shale shaker, vertical cuttings dryer and decanter centrifuges of big bowl and medium size.
