As every solids control company is trying to take part in oil show to improve product over sea, there will be a lot need consider for prepare an oil show out of China to make a good show there.

 

1. Will you bring equipment to the show? Is it a big machine or small like a part? How long time for prepare the machine and time schedule for delivery including cleaner custom?
2. How do you delivery the machine? By air or sea? How do you arrange for custom clearance? You delivery goods and stock somewhere over sea? Or you will delivery back after show? How?
3. Which way is better to save time and cost? How do you manage over sea delivery and stand set up?
4. What items do you need prepare? What documents or brochures you will bring? Do you need any tools for prepare stand? How to arrange the stand design? Do you need posters? What kind of design?
5. How to manage storage items? Do you have a partner locally? Or do you need rent a warehouse for keeping the equipment?
6. How do you arrange lay equipment in your stand? How much cost will happen?

 

There are really a lot questions need consider and prepare before an over sea oil exhibition , GN Solids is one of the leading manufacturer in China and take part in over sea shows every year like Australia trenchless show , Australia mining show , OTC America exhibition , Moscow oil show , Canada trenchless show , etc. . All these show gives good promote of GN Solids Control by a good prepare of the show.

As Libya is not stable in policy, drilling field and oil service field is also suspended. However, other market is North Africa is good, like Algeria market. The active drilling rigs are better than other field. GN Solids Control recently delivery over 30 sets drilling mud centrifuge and over 5 sets of vertical cuttings dryer to Algeria for solids control and drilling waste management service. As China leading brand of solids control, it is also our responsibility to support Algeria market with centrifuge and vertical dryers.

 

GN Solids Control have partner with EMEC for several years, the largest mud service company in Egypt & Algeria.  Many people working for Baker Hughes, Halliburton was working for EMEC before. From this point, you can know EMEC is really professional in this field with many years jobsite experience.

Except for EMEC, GN Solids Control also has many different big partners in different site. Like in Iran, in Argentina, in Brazil, in Australia. GN Solids Control have branch office in USA and Russia. The USA office is in operation about 2 years; the Russia office is in operation about 1 year. With partners and our branch office, GN Solids Control equipment is exported to over 60 countries and areas. Each year with over 150sets decanter centrifuge, over 250sets shale shaker with Hi G dryer shaker with mud cleaners, over 300sets mud agitator, over 200 sets centrifugal pumps etc…

 

Because of oil price going down, many drilling rigs stop. But drilling waste management field is more active because of the strict policy on environmental protection. In China we have no-pit drilling project, which require more on line drilling waste management equipment. Like Hi G dryer shaker, high speed decanter centrifuges, vertical cuttings dryers, screw conveyors to transfer drilling cuttings, screw pumps / centrifugal pumps etc.

 

If you are working in this field and need more support on solids control equipment / drilling waste management equipment, pls contact us freely for any requirements.

Recently, GN Solids Control, the first API certified Chinese solids control company, has delivered to CNPC 5 sets of vertical cuttings dryers, and those vertical cuttings dryers will go to work in Algeria in Africa together with the service projects with CNPC.

CNPC is the TOP oil company in China, ranking at leading place among the global top companies also. CNPC has projects and oil fields not only in domestic China, but also all over the world, like in South America, Africa and Middle East. GN Solids Control provides equipment and mud recycling systems to their domestic subsidiaries some times, like this order. And also, when CNPC are doing project outside China, some of their contractors are also GN Solids Control’s clients.

GN Solids Control is the first China solids control company who designed the vertical cuttings dryer, and each year GN engineers improved the design of vertical cuttings dryer. In March, CIPPE Oil Show in Beijing, GN showed the 4^th generation vertical cuttings dryer. with higher rotating speed and larger G-force. And the useful air knife design, helps the screens from blocking.

With a higher rotating speed and some necessary designs for avoiding blocking for screens, enables GN’s vertical cuttings dryer to have special advantages, which is that, it is not only suitable for OBM and SBM, but also fit the WBM which normal vertical cuttings dryers can not do. It just meet the recent request of some new drilling practices. In order to save cost and reduce the bad effect on environment, at the shallow level they use water based mud, and for deeper level, they use oil based mud.

In this case, the end users don’t have to change new equipments to do the waste management services, only one waste management is enough for the complete drilling procedure. It has been well proved and receiving good feedbacks even from Baker Hudges and Shell.

COSL, a large oil field service company belongs to a giant national owned company in China, only focus on the best quality equipments from the reliable manufacturers. Before, they always buy from international famous brands, some are from USA and Europe, especially when they are purchasing highly advantaged equipments.

This time, they purchased from GN solids control a complete centrifuge system for oily sludge separation. Comparing with other materials, the oily sludge is more heavy and of less liquidity. That’s why before entering into the centrifuge for separation, the oily sludge need to be treated and dissolved by some chemicals and the polymers would change somehow to be easier treated. After that, they add some liquid into the material to dilute it before entering into centrifuge.

This same model centrifuge is used in many jobsites both domestic and abroad, for the solids control, waste management and oily sludge, some even used for industry fields. By combining with different other equipments, like shale shaker, desilter, desander cones, and vertical cuttings dryer or high-G shaker, this model of centrifuges plays different roles. But for every role it plays, it plays well. As an equipment manufacturer, how does GN achieve this?

1. GN values the customer feedbacks. Depending on different jobsite conditions, the feedbacks are not same. For the same equipment or system, there may be both good and bad feedbacks. In case there is complaints from end user, GN always try best to find a way to better the design.

2. GN is quick to response. Always, the new design will be added to the equipments soon, and tested on jobsite, if it brings good effect, GN will add it in every new product without delay.

3. although the equipments are updated each year, GN tries best to make the main spare parts to be same for main equipments, easy for clients to do maintenance in future use.

The decanter centrifuge has a wide uses depending on different applications , it can be used for de – water hydrocyclone under flow , remove the drilling solids from active drilling mud , or revove colloidal solids particals in weighted drilling mud . The centrifuge can be used for unweighted drilling mud , while mud recycling again and again , the drilling mud will get heavier and heavier , then the heavier mud will be no good to reuse again .

 

There are different design of decanter centrifuge , according to separation size , there will be designed profor G force to reach separation point . G Force is a very important parameter for centrifuge application , while the G force get higher , the separation factor will get higher but will need higher standard to keep sure centrifuge screw and bowl to be suiltable of the G force . For a same decanter centrifuge , the higher G force will increase mud flow treatment capacity also . However , the increasing G force eventually reduces solids conveyance capacity due to torque limitation . As the g force increase , more and solids will be settled in the bowl bottom of inside , then solids will be more tightly and more conveyor or torque will be required to remove the solids out of bowl .

 

The solids dryness from decanter centrifuge can be adjustable by adjust fluids outlet height plate . The dryness is commonly considered as a direct indication of a centrifuge performance , but the test results has shown that the dryness of solids from centrifuge is more correctly as a fuction of partical size . The pond depth will control both fluids residence and cake dryness .If you increased pond depth , the residence time will increase separation and separation performance will be better . Any how this will be depending on the drilling condition and fix a suitable depth .

Mining Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic material of an ore. For the contractors, tailings is an external cost of mining. More and more countries and governments keep developing the mine regulation on the environmental safe purpose and proper mine tailings pond solution is must required by laws. For a responsible company, Tailings dams are often the most significant environmental liability for a mining project. GN special designed slurry separation system can be used for tailings dam treatment from the tailings pond. Our engineer team will required a test report of the particle size of the solids and give you proper solution to less the burden of environment. For example, the shale shaker is different with oil & gas drilling used shale shaker, it is mining used shaker with big treating capacity. The shaker screen is polyurethane material which last longer than traditional stainless steel shaker screens. The desnder, desilter material is special made with ceremics insert. For coal and oil sands mining, tailings means fine waste suspended in water. GN dewatering unit with polymer mixing unit is applied for separation of fine solids under 5 microns. GN waste dewatering unit has been applied in over 50 countries in the world, the applications including oilfield waste management system, tunneling waste water treatment, mining tailings waste water dewatering, etc. Not only for mine tailings treatment, GN dewatering unit with dewatering centrifuge can be also used for diamond core drilling. GNLW223 dewatering centrifuge has been used in many countries in the world for mining diamond core drilling purpose. We also provide solids removal unit including the mini decanter centrifuge as a compact design system which can be applied for core drilling. GN solids America( with headquarter GN solids control) will attend Global Petroleum Show in Canada, Calgary from June 9^th to 11^th, pls visit our booth and check our dewatering centrifuge for mining tails slurry separation.

Shale shaker screen is the essential part in filter solids from liquid, and it is disposable part in various drilling that need to replace all the time.

Because of the drilling fluid that contains corrosion, abrasiveness and heat,it needed to filter solid particles for long period time.  Generally speaking, the material of shaker screens are all constructed in stainless steel and the wire which disposed by heat treatment technology. The auxiliary support structure is made of steel plate, galvanized sheet, and others combined materials.

With the continuous development of science and technology, in order to enhancing the filter effect of screen, the corrugated- shape screen was developed. It is improved and upgraded from flat type screen, started to be implied in the mid-1990s.

 

Corrugated- shape screen synthesize the advantage of common crochet screen and orifice plate adhesion screen, but it is based on the structure size of shale shaker will not be changed, and the frequency and exciting force of vibration exciter will not be changed as well.

 

The advantage of the corrugated- shape shale shaker screen is that it breaks the limitation of traditional plate screen, because of the unique wave pattern of screen, it is not only has the service life increase and as well as filter effect of orifice plate adhesion screen by increase the filter area of screen more.

 

When the drilling fluid flow to the screen surface, the solid phase will flow to valley bottom of corrugation, vertical surface can provide more filter area for drilling fluid, so compared with flat surface screen, the wave screen has through capacity. The thruput is larger 30%~40% than orifice plate adhesion screen and other flat surface screens. And diamond screen increases the residence time of drilling fluid on the screen surface, has a better sieving effect.

Screw conveyor name “ Auger ” also to delivery solids particals on drilling site . It will contains one set motor with low power requirement , cause the screw can working continuously , the working for transport solids will be continuous as per request and require minimal operator actually .

The screw conveyor normally used to delivery drilling cuttings from shale shaker from one point to another point depending on clients request . As the screw conveyor is steel material and mainly working to delivery straight away . The solids will be discharge under one end of screw conveyor to another screw conveyor or drilling cuttings storage . There are different length and diameters for screw conveyor depending on different applications . The diameter normally we have is 12 inch , 14 inch and 16 inch , the length of screw conveyor we have normally 24 ft , 36 ft and 48 ft . Any how , the size of screw conveyor can be customized .

There are horizontal screw conveyor to delivery solids horizontally and purpose is the delivery solids far away somewhere . Such as the screw conveyor for collecting drilling cuttings from shakers, it maybe 2 or 3 or even more shakers discharge need collection , we will choose an horizontal screw conveyor to collect solids from all shakers . If we use for feeding vertical cuttings dryer , we will have to choose an different layout. The screw conveyor need collect cuttings from one screw conveyor and feed drilling cuttings to dryer on top opening . The second screw conveyor will be goes from a low position to a high position by delivery solids from ground to top .

Other than screw conveyor , there are other equipment for solids transport Please contact GN Solids for inquiry or question .

The fixed speed control panel is single speed control panel with starter / stop functions. Relatively speaking, this panel is easy to produce with lower cost, and the operation procedure is also very simple. For customers who only need single speed centrifuge like 3200rpm or 2700rpm or 2200rpm, may go to this single speed centrifuge with single speed control panel. However, if the experienced customer wants to achieve better performance, they may go to variable speed centrifuge with variable speed control panel. With this panel, the speed can be adjusted flexible from low speed to middle speed to high speed. Another, differential speed can also be adjusted for better performance.

GN Solids Control variable speed control panel with 3 units ABB frequency transducer, can adjust the speed in a very convenient way. The dimension of the control panel is about 1.5m X 0.8m X 1.7m.

 

For all other equipment with motor drive, all can be design into variable speed with ABB frequency transducer. Like variable speed screw conveyor, variable speed feeding screw pump, variable speed vertical cuttings dryer etc.

 

Variable speed screw conveyor with ABB transducer panel is widely used in drilling rigsite. The customer can adjust the drilling waste / drilling cuttings transportation speed in a good way.

Variable speed feeding pump for centrifuge with separate single ABB transducer panel is also very popular. In this case, the customer can easily change the feeding rate without effect from centrifuge.

Variable speed vertical cuttings dryer is really good idea because of the large motor will produce very high prompt current when starting. With this variable speed control panel, the big motor 75kw can be started smoothly and stably.
