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.

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.

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.

Vacuum pumps are GN’s new design and new products for the oily sludge transportation. Besides oily sludge, it could also handle many other kinds of materials like the sand and small rocks from construction, the drilling cuttings from the solids control system, industrial waste, animal waste, mud tank bottom sludge, and industry slurries. Take the big pump model as example, the GNSP40A, It could handle the particles with large size up to 50mm and with solids content up to 80%.That’s why it is also called solids pump.
Ever since GN built the first set of vacuum pump and put it into market, it gains lots of eyeballs. Till now, all vacuum pumps the GNSP40A’s and GNSP20A’s have been sold out. New orders are coming all over the world, and the coming 12 sets which are scheduled to be ready by end of June are already purchased by some clients. GN Solids Control is planning to produce more as stock to matching the demands of clients.
Why could those pumps become so popular?

1. Cause it is suitable for the applications faced by the operators. For example in the oily sludge, there are always lots of particles which are large for normal pumps and also it is of high viscosity. This vacuum pump could handle the comparably bigger particles with high solids content.
2. It is suitable for Explosive Proof standard, even for IECEX/ATEX Zone 1. Cause it is all mechanical equipment, no electric components applied, it is fully explosive proof.
3. It could suck the material from 100 meter away and discharge it to around 1000 meter away. That’s why some operators are using it to transfer liquid from a hole deep into underground with an opening from ground.
4. Small in size and easy for transportation. The GNSP20A and GNSP10A are portable with wheels, total volume smaller than 2 cubic meters.
5. Powerful, which is the last and most important feature.
Those 2 vacuum pumps are of model GNSP40A, with a large capacity of 40cbm per hour. They are just ready for being delivered to a UAE client.

Early in May, Trenchless Asia exhibition was held in KLCC, the center of Kuala Lumpur, the capital of Malaysia. It is not a big exhibition, which occupied only one hall of the exhibition center, but it is always a professional one, in which all big players in the trenchless industry was involved, like Vermeer, American Auger, TT-Asia, Ditch Witch, Bauer, GN Solid Control, Tangxing, Goodeng, and etc.

powerful pump for slurry transferring

GNSP Slurry Pump

Cause this exhibition is a bit overlapping in timing with OTC in Houston, in which GN has two big booths, GN only arranged a small booth in Trenchless Asia, and brought one single exhibits, a newly designed portable vacuum pump.
In Trenchless industry, this pump could be used to transfer the mud from inside of the pipe-jacking line, or to be used to transfer the slurry out from the pit. In this exhibition, the experts and professional operators also developed new applications for the vacuum pump, like to transfer the clay particles during construction, or animal waste or toilet waste…
Besides those above mentioned applications, the GNSP series vacuum pumps are mainly designed to transfer the drilling cuttings and oily sludge for the refinery industry or the tank bottom cleaning works. It could handle the material with solids content up to 80%, with particle size up to 50mm, from 50 meter away to 500 meter’s distance.
In this exhibition, customers discussed with GN sales team about the future inquiries and opportunities. For most of end users, GN Solids Control is a well known brand with a good reputation. In fact, lots of big brands of pipe jacking or HDD rigs are packing GN’s mud system because of GN’s reliable quality and responsible service.
Till now, GN Solids Control has sold equipment to more than 70 countries of world, and GN brand is accepted and appraised by many national owned drilling companies.
