There are several different types of drilling muds used for different drilling conditions, mainly divided into 3 types, the water based mud, oil based mud and SBM. The mostly used ones are WBM and OBM.

For deep well drillings, the OBM is most common solution. Considering it’s components, the oil based mud is more expensive than water based mud, that’s why as much as mud should be recovered from the waste. Meanwhile, the OBM is more harmful to the environment if the cuttings from drillings are not well treated before discharge. As leading manufacturer and solution provider, GN Solids Control has designed and supplied to many different end users with its professional solution for drilling cuttings treatment. For oil base mud cuttings, recently, another new set of such system was successfully use in CNPC, one of the 3 largest oil companies in China, both their engineers and operators are giving good comments.

cuttings treatment system

This system includes:

1. GNCD930 vertical cuttings dryer, which is specially designed for treating the oil based cuttings, it is like a washing machine. By using screen baskets of different mesh sizes per cuttings condition, and after the vertical cuttings dryer, the oil on cutting could be reduced to below 0.5%.

2. The second treating machine is a high speed decanter centrifuge. In this project, the end user chose GNLW363CG-VFD, a 14 inch diameter bowl decanter centrifuge, with variable speed up to 3200RPM. It is used for further treatment of drilling fluid discharged from the vertical cuttings dryer.

3. Transferring equipment. For transferring the drilling cuttings, GN has different suggestions based on customers’ jobsite layout and cuttings location. Normally, if the cuttings treatment system is alongside the rig and used for treating the cuttings direct from solids control system, screw conveyor is good choice to collect cuttings from shaker and transfer to hopper of vertical cuttings dryer. If the wed cuttings are from a pit or pond, we recommend GNSP vacuum pump.

As long as there is a drilling project, there must be a solids control system coming along, no matter it is for land rig drilling or offshore drilling far in the oceans, an efficient solids control system are vital for the drilling fluids recycling and drilling cuttings transportation, especially for the offshores.

GN SHAKER

GN SHAKER AND MUD CLEANER FOR OFFSHORE

In offshore projects, cause of the distance from the land, all material must be used to the most, the most liquid should be reused and least cuttings to be transported back to land. The shaker is used for separating out the most of solids, for handling the heaviest burden, the high performance and strong structure of shaker is quite important. Following features of GNZS series shakers ensures the shaker’s quality and performance:

1. A high G force up to 8.5G powered by Oli Vibrator for a good separation work.

2. Stainless steel shaker deck is stronger for handling the high G force.

3. Patent design of rubber sealing, effectively avoided the leaking of mud.

4. Two different models, with 3 or 4 pieces of shaker screens, providing large treating capacity of 120cbm/hr or 140cbm/hr.

5. Special patented way for changing screens, safe and human oriented.

Talking about shaker screens, as is known to all, shaker screens’ quality greatly affects the shaker’s performance. That’s why GN has built up a separate screen factory for better control over screen quality. In this shaker screen factory, GN is the first and only one who uses robot for welding and cutting, and GN’s screens are in accordance with API RP 13C, an accurate API number and a high conductance with a good screen frame structure made of composite material.

For more information, welcome to contact GN Solids Control directly and welcome to visit GN factory at any time.

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.

Last week, one international contactor for mining industry started their project in Australia, among the separation line, two green colored equipment were significantly shown. They are big bowl centrifuges from GN Solids Control, a leading manufacturer for industrial separating equipment manufacturer based in China.

GN Solids Control has been designing and producing the separating equipment like shale shakers, mud cleaners, decanter centrifuges, vertical cuttings dryers for many years. At first, the equipment are mainly used for the oil and gas drilling solids control systems, and later, as GN’s quickly increasing development of technology and producing capability, GN Solids Control has enlarged its centrifuge model range from 14 inch bowl to bigger ones and smaller ones. Those 2 sets of GNLW764A decanter centrifuges are till now the biggest sized centrifuges made by GN Solids Control, with a bowl diameter of 30 inch and a treating capacity up to 120cbm/hr.

Besides the giant bowl decanter centrifuge GNLW764A-VFD, GN Solids Control has various centrifuge models with size as small as 9 inch diameter bowl, up to 30 inch diameter bowl, including the 14 inch bowl , 18 inch bowl, 22 inch bowl and etc.

GNLW764

For each size, there are different models available per different bowl length diameter ratios. Normally the comparably longer bowl a centrifuge has, a cleaner separation result it could give. Among GNLW series decanter centrifuges, take the 18 inch bowl diameter as example, there are different ratios like 2, 3 and 4. GNLW452 is a stout shaped decanter centrifuge with middle speed and shorter bowl, which is mostly used for barite recovery in a solids control system based on the barite size and gravity. GNLW453 is a high speed centrifuge for waste management systems, or as the dewatering centrifuge, for fine particles. While the GNLW454 is quite suitable for waste water separation with a longer bowl up to 4 times of bowl diameter, around 61 inches.

GNLW764, the 30 inch bowl diameter centrifuge has a bowl length-diameter up to 4. And this giant could separate quite fine particles at a large capacity, even after a dewatering unit.
