In coming month, from December 12th to 14th, a new exhibition will be held in Thailand, focusing on the oil and gas industry, for both land rigs and offshores. The exhibitors cover the drilling industry, from the upstream to the downstream. During the exhibition, there are also professional conferences to be held.

About GN Solids Control

You may already know the three biggest oil and gas exhibitions in the world, one is the OTC in Houston, which is scheduled in each May in Houston, the technology center of the oil and gas industry, one is CIPPE which is held in Beijing, the capital of China, because China is becoming the biggest manufacturer and an up-rising technology R&D center, and also the ADIPEC, which is based in Abu Dhabi, one central city of Middle East, where the largest oil is located in. This exhibition in Thailand is hosted by the same company as ADIPEC.

Value of Asia: Asia has the largest population in the world. China and India are two of the biggest oil consumers and also the equipment manufacturers. Also the south Asian countries like Indonesia, Thailand, Malaysia and Singapore are also exploring oil reserves in adjacent seas. Some international big oil companies are locating their branch companies in those countries, and their business and contracts are covering regions as far as Africa.

Exhibition Name: Future Energy Asia
Exhibition Location: BITEC, BANGKOK, Thailand, from Dec 12th to 14th
GN booth: D40.

GN Will Bring Screen Samples to Exhibition, why?
As the leading solids control manufacturers in the world, GN Solids Control has the complete solids control and waste management equipment line as turn-key solutions, and GN has a separate workshop for shaker screens, equipped with an automatic screen producing line. All GN frame screens are made of composite frame, by robot cutting and welding and pre-tensioning and heat pressing by machines to minimize the faulty in production and to ensure the precision.

GN BIG BOWL CENTRIFUGE

By far, the decanter centrifuge is a quite efficient equipment for separating the solids from the liquid, which is widely used in many industries form the winery, plant oil to the energy industry like the oil and gas drilling, waste management, cuttings treatment and oily sludge separation. Not long ago, 2 sets of GNLW764-VFD centrifuges were delivered to a desert jobsite for a coal mine project, for washing the coals.
When a place is remote, especially in a desert place, all resources are more precious than usual. In that project, the decanter centrifuges are only a part of the whole project but are playing an important role. They are requested to run continuously and to treat around 100 cubic meter material in each hour, in order to save cost by two means: one is to collect the limited water to be reused in next washing procedure, the second is to dry the coal and finally change it into money. The more water to be recycled, the lower cost the project pay for, and the more coal to be collected, the more benefit the project earn from.
Decanter centrifuges are one of GN Solids Control’s core products, and GN has centrifuges for different applications, including: mining and other industry, oil gas drilling solids control and waste management for the cuttings and drilling mud, oily sludge separation works like the waste treatment in refinery and from tank cleaning, the animal waste treatment in farmlands, food industry like the plant oil and wineries.
In a word, an efficient decanter centrifuge helps the end user to cut cost, save money and increase the final products quality, like the purer liquid and drier solids. If you have such need for centrifuges or need more information about centrifuge, welcome to contact GN Solids Control for consultancy.

Just last week, GN Solids Control has finished a compact mud recycling unit, with full steps for separation for one of the largest oil giants in China. This system is to be transported to the jobsite by end of this year.

This system has 4 steps of separation, including:

1. GNZS703F. Shale shakers are always the first step for separation, because of GN shakers’ high G force and accurate API complied shaker screens, this shale shaker can efficiently separate out all particles larger than 100 microns, there in hence to help with prolonging the service life of the centrifugal pump after the shaker.

2. GNZJ703F-1S8N Mud Cleaner. Mud cleaner is a combined machine of desander and desilter, at a smaller foot print. It uses interchangeable shaker screens as GNZS703F, 2 centrifugal pumps are used to feed the desander and desilter respectively.

3. GNSP series Centrifugal pumps are also GN’s own products. For material choosing, GN used the high quality anti-weary material as pump body material by hard ductile iron alloy, and the main pump body is thicker than other manufacturers’. All GNSB series centrifugal pumps are using stainless steel mechanical seals.

4. Tank and skid for above mentioned equipment. Above mentioned equipment are located as 2 blocks. One block is a skid with lifting and anchoring corners just as a 20ft container, and the shale shaker and mud cleaner are located in the skid during transportation and operation. That design facilitates the operator for transportation or lifting the whole skid onto a tank, no to adjust each equipment or pipeline’s position.

5. A tank with compartments are designed to storage the mud from the shaker and from the desander/desilter. On below the tank, there are some slots for installing the centrifugal pumps. The whole outsize of the tank is also same as a 20ft container with container corners for lifting.

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.
For more information, welcome to contact GN directly.
