Further more, GN Solids Control upgrade its company logo. Almost all equipment documents and brand new equipment will start to use the brand new logos from now on.

Screw pump, is mostly used for feeding decanter centrifuge. We match Netzsch brand screw pump for GN centrifuges, and export over 250sets screw pump each year. Recently, we have one client from Middle East who need two sets screw pump for feeding the centrifuge and will use them at offshore drilling platform. After we provide the quotation with technical specifications and commercial price, the client is very happy and issue Purchase ORDER TO us within one week. The payment came last week, and we will dispatch the screw pump in next two weeks very soon.

Except for screw pump, GN Solids Control also export large quantity of centrifugal pumps, shear pumps, submersible slurry pumps, and pump electrical control panels to overseas and domestic clients. GN Solids Control can manufacturer the pumps and lower down the production cost and offer best price and high quality to the clients.

In year of 2015, we export 30 sets centrifugal pump with electrical control starter to Africa market. The client is very happy with the working performance and signs the long term supply and purchaser contract with GN Solids Control. Except for the various pumps, GN Solids Control main target is on the sale amount on decanter centrifuge, vertical cuttings dryer, and mud mixing systems.

Decanter centrifuge have a good market in the past five years. Many drilling company, mud service company, oil Service Company become to accept and try China brand centrifuges. After they try GN centrifuge at jobsite, they love the centrifuge and buy more. GN centrifuge can work similar as US brand centrifuges, but the price is almost half of US brand centrifuge, or even less. That is the main reason we can get more centrifuge orders from big clients.

Vertical cuttings dryer is not that popular as centrifuge, because this may necessary or may not necessary for various countries. Some countries have strict environmental protection laws for oil industry and the drilling contractor may need vertical cuttings dryer to treat the drilling waste management . Some countries may not.

The market is down, we are supplying service with lower price, we are waiting for the contract. Another factory is taking more days off. As the saying goes, the economic crisis is not only your neighbour lost job, yourself is also being fired. Nowadays more and more oilfield companies have been suffered hard days. And some may change business, especially small companies, keep lower and lower price will never last too long.

GN is mainly target on overseas market, high quality equipment and reasonable price.  GN Solids Control equipment have taken lots of drilling site in Middle East, Africa, Russia, America, Brazil, Australia etc.

GN Solids Control equipment including: shale shaker, shaker screen, mud cleaner, desander, desilter, decanter centrifuge, mud agitator, mud gun, centrifugal pump, screw pump, vertical cuttings dryer, screw conveyor, High G drying shaker etc.

Keep focusing on solid liquid separation equipment, making better solids control equipment, drilling waste management equipment for oil drilling projects. For HDD, environmental industry and so on. And this will be where we can make some differences, from each and every details. So in the new year, we will still keep focusing on the main equipment, and change the world.

Keep tune on GN Solids Control, in 2016, we will have big improvement on shale shaker, decanter centrifuge, and cuttings dryer. Also we will have our TDU thermal desperation unit ready, well tested, and probably some early bird client will use it on field. Looking forward a new challenging year.

As the first API Certified solids control manufacturer in China, GN Solids Control has been growing rapidly and the product range is always changing with time. GN’s products mainly focus on following fields:

1.Drilling mud solids control systems/ equipments

2. Drilling waste management systems/ equipments, including the drilling liquid and drilling cuttings further and final treatment

3. Mud recycling systems for HDD projects, water well drilling projects, and slurry plant/desander plant for TBM and etc

Since the technology and configuration of equipments are mostly stable for solids control and mud recycling systems. while the with an eye on the environment protection issues, the waste management solutions are more and more important for the oil and gas drilling industry, GN also designed more products for the waste management industry. 

GNGH series Solidification unit is one of the new products GN has designed in the past year.

GNGN Solidification Unit GN firstly designed was for another international company, who has business and projects in all over the world. In order to solve a separation problem happened during their work, they came to GN and jointly designed this solidification unit. The first set of solidification unit was soon put into use to the jobsite and feedbacks are conveyed to the designers.

After that, GN re-designed the solidification unit, enlarged the treating capacity and simplified the electric control panel in order to make it more suitable for the drilling cuttings conditions. Soon the other set of such unit was put into use at another jobsite and orders repeatedly come.

Comparing with the drilling rig in a drilling rig system, the solids control system is regarded as a spare parts, because of the consumption and service time of the solids control system is shorter than the drilling rig’s other seven systems. And in the solids control system, as the shale shaker is the most important equipment in this system and the shale shaker screens are the most consumable spare parts in the solids control system.

There are not so many shale shaker makers, and the shaker screens produced by the shale shaker manufacturers are not enough for the market and also because of the high price of the original shale shaker screens,, many end users are searching for replacement screens from other suppliers. Some suppliers are also solids control manufacturers while some are only screen suppliers.

GN Solids Control as the first API certified solids control manufacturer in China is professional in screens:

1. as the leading solids control manufacturer, GN designs and make its own brand shale shakers, so GN knows the screens better, and knows how to make the best screens.

2. shale shaker is one of GN’s main products, in order to better control the screens quality and to improve the screen quality, GN established a separate screen factory.

3. many worldly famous drilling companies who use Derrick, Swaco or NOV shale shakers, are using GN’s replacement screens because of the cost effective.

In this situation in oil and gas drilling industry, every company and end user should take care of the cost as the most important thing. And in order to better control the quality and cost, GN improved the screen producing technology and now GN Solids Control is promoting the shaker screens at a very competitive price. May you have interest, welcome to email to [email protected] for more information.

 Besides shaker screens, GN Solids Control is more professional in:

1. solids control system and equipment for drilling.

2. drilling waste management systems, zero discharge systems.

GNGH Solidification Unit is actually a new contribution GN Solids Control brought to the drilling waste management industry with year 2015. It is realistic and final treatment for any drilling cuttings discharged in the drilling waste management gear like GNCD930C vertical cuttings dryer and the drilling spend decanter centrifuge GNLW363CG-VFD.

The significant process of drilling cuttings renforcement unit is to add a acceptable ratio of hardening real estate agents to the drilling cuttings as a way to prevent them from just one into the soil. The hardening agents should be well combined with the drilling cuttings for any certain time, then by using physical and chemical change, the harmful and poisonous components are transformed, enclosed and fixed into safe elements and become some other solids with out pollution and to be used seeing that construction materials. GNGN Renforcement Unit is the final remedy for the drilling cuttings. Around the globe, people and government are definitely more and more aware of the necessary involving limiting the pollution via oil and gas drilling. No land would like to sacrifice the environment for any temporary economic benefit, along with the traditional solids control and also the waste management remedies are not enough for these requests. The equipment manufacturers, drilling companies and oil services companies are looking for solutions just for this trend, and among all, GNGH is an more efficient solution as well as already tested on construction site.

Last week the China president Mr Xi Jin ping visited Tehran, Iran, on his trip for 3 Middle East countries including Saudi Arabia, Egypt and Iran. Since the sanction caused by the nuclear problem was finally lifted, Iran is back to world economy and will soon become active. On President Xi’s trip, the leaders from both countries discussed about future relationship and cooperation.

Although the world crude oil price is still at a low point and affects a lot on Iran economy, the future of Iran economic is still trend to boom. Iran Oil Show is scheduled on May 5th to 8th, 2016, in Tehran. It would be the 2nd time GN Solids Control attends Iran Oil Show. Last year, GN brought to Iran a high speed decanter centrifuge and it was purchased by a local oil service company. It attracted lots of visitors.

This year also, GN Solids Control booked a booth in the international Hall, Hall 38, with 33 sqm booth. In this oil show, GN plans to bring a decanter centrifuge also, with the model GNLW363CG, fixed speed centrifuge with speed up to 3900RPM. This centrifuge is designed and made per international highest standard. Bowl main material is made of SS2205 by centrifugal casting. Centrifuge impeller is protected by tungsten carbide tiles, each tile is of 4mm thick and when worn, it is easy to change 2 tiles, one here and one on opposite position, no need to adjust the dynamic balancing. The bearings are genuine SKF bearings, for better performance and longer service life. This centrifuge is equipped with fixed speed control panel, besides this ,GN also have GNLW363CG-VFD with VFD control panel with positive pressurized control panel with smart PLC touching screen.

News came yesterday, the crude oil price dropped again yesterday, and economic observers have shut up their mouths for expecting the bottom price of crude oil. Some people even say it is not the very bottom low price yet. Some professionals expect the price to be around 20 dollars and some negative views show that their idea is around 10 dollars.

All the oil related companies are struggling a way out for the bad situation. On Tuesday, BP announced that it will cut its global positions by 5% in this situation, Petrobras in Brazil reduced their investment plan for the third time in the past 6 months. The valuation for Shell and Exxon Mobil dropped respectively 11% and 4%. During the past 18 months of the continuous going down of oil price, hundreds of staff in the oil relating industries lost their jobs. Now the media are calling this an Oil Crash.

How to survive this oil crash now is a question to everyone in this business. Although fronting the bad situation, GN Solids Control has done a good work in the past year.

1. stable pace for the traditional solids control. GN Solids Control has been the leading solids control equipment and systems for years because of the good quality and performance of GN products, and Solids Control now still occupies a certain share of GN’s products.

2. improve the existing equipments’ designs and performances, update the material to provide a longer service life. In the past year, GN Solids Control has updated GNCD930C vertical cuttings dryer’s design and also greatly changed its GNLW363 series decanter centrifuges. And also the shaker screens producing technology is updated.

3. exploring the new equipment or systems to fully meet clients’ requests. In year 2015, GN Solids Control produced more GNDU2000 dewatering units together with dewatering centrifuges, and GN developed and put into market GNGH series solidification units.

200gpm mud system is small and compact mud system which is usually used for small water well drilling rig or small HDD rigs. The mud system can recycle, clean the mud from mud pit and return it back to drilling rig for reuse, via mud pump. GN 200gpm mud system have been exported to Australia, Asia countries, Niger, Kuwait etc.  Correct way to use 200gpm mud system is very important part of the contract.

1） General introduction of GN 200gpm mud system

200GPM Mud System is a customized mud recycling system and clarification system for drilling rigs designed by GN as per client’s requirements. This system has a working capacity of 45 m3/h. This system is designed to include 2 levels of solids control and clarification procedure. In order

to have a compact structure, this system adopts the structure as integrating together a shale shaker and a desilter, which is a Desilter Mud Cleaner with Model GNZY753E-4N. First level separation is by a GNZS752E Linear Motion Shale Shaker, and second level is combined of a

4N Desilter and a GNSB4×3A-11J Centrifugal Pump. Centrifugal pump provides enough power for Desilter and drilling mud was treated via centrifugal separation by Desilter, such is main principle of the second level. Meanwhile, a GNSLM25 Jet Hopper was equipped on tank to be

used for adding and deposition drilling mud, thereby provide the rig with suitable mud for drilling technology requirements.

2） Installation of GN 200gpm mud system

Make sure the operation field is even and clean, and make the foundation. Install and fix GNZY753E-4N desilter mud cleaner and GNSLM25 jet hopper ( other equipments are installed before delivery).

Connect all pipelines, walkways, guardrails and stairs. Make sure all flexible parts can easily to swirl safely and flexibly after installation. Locate the mud tank as per drilling site and connect all connector clips for solids control equipment control line.

Dewatering system is used in a complete zero discharge waste management system for an oil and gas drilling rig. It is used to further treat the drilling mud after a certain operating time of the mud system. There are more and more fine and extra fine solids particles in the drilling fluids have to be separated out in order to make the drilling fluid suitable for reuse.

But the extra fine particles are to small even for the high speed centrifuges, that’s why, only physical separation is not enough. We have to add some chemicals into the fluids and flocculate the small particles into larger ones for the centrifuge.

What is the procedure?

There is a dewatering unit used for this function. In the dewatering system, there are some dosing devices, one or more chemicals are used for the system. Dosing device add the chemicals, and some valves are used for measuring and feeding the water. It need some certain time for the chemicals to be well mixed and ready for use. And there is a joint of pipelines before the dewatering centrifuge, where the ready for use chemicals enters the centrifuge together with the drilling mud to be treated.

What chemicals to use in the dewatering unit?

Normally poly aluminum chloride (also called P.A.C) and poly acrylamid (P.A.M) are used in dewatering system as cheicals. the amount of usage is depend on solid concentration in the liquid waste, and the mud condition and the depth of drilling are factors also.

GN other Waste management equipment/ systems.

Few days before, GN’s waste materials management equipment for three or more rigs passed the ordering and started running in Nigeria. Total 33 units tools were involved including the squander cuttings drying equipment, extra fine solids separation products and transferring equipment. The photos was taken by the commissioning engineer when completing the installation and having. The client is one of the big drilling contractors in Nigeria, this is certainly already the 3rd order out of this clients. Before this venture, the client order 10 products waste decanter centrifuge in addition to 1 complete mud flower system from GN Solids Control. Below links to another 2 projects for guide: 1 . Liquid Mud Flower System for Africa Drilling 2 . Ten sets GN Decanter Centrifuge for South africa Drilling Company These thirty three units equipment are detailed as below: 3 arranged vertical cuttings dryer that is main drying equipment to get waste cuttings, with the maximum. speed up to 1200 RPM, the G force can be up to 750.

6 value packs high speed VFD decanter centrifuges would meet the client’s distinct requests on operation rate and waste conditions. Entire 9 unit screw pushes, with 6 of them to get feeding the effluence cleared out from the vertical cuttings dryer to decanter centrifuges, even though the other 3 unit intended for flushing to clean the cuttings dryer. 15 set mess conveyors are located on web-site accordingly for transferring the actual drilling waste to the dryer unit and collecting the actual solids discharged from the dryer and centrifuge.

GN solids control has designed and produced hundreds of  mud tank system for oil drilling rigs since 2008. We were also invited by some tenders of ONGC, Oil India etc. oil company for their mud tank system. If you have requirement for solids control equipments and mud tanks system, pls contact with GN solids control sales.

Specifications of painting/ coating:

Internal tank with 2 layers of anticorrosive coatings, tank outside with 3 layers of coatings, sandblast before painting. Two pack Epoxy zinc, thickness 75 μ  for inside tank,                                                                                        Two Pack( first layer and middle layer) Epoxy hi-build containing anticorrosive pigmentstwice,  thickness 250 μ   , Surface pigmented( top coating) with high quality light fast PU pigments, thickness 70 μ for outside tank.

Mud tank materials:

Normally we make rectangular tank for mud tank system, sometimes we also make cylindrical tanks when rectangular tank is not suited for the project, for example, limit of space, large volume, cheaper cost. For rectangular tanks, we can make it open tank top or closed tank top or with gratings cover. The mud tank dimension is calculated by the required storage volume, we can make standard 40ft container size tank and customized size tanks. The body(shell) of the tank is made of 6mm thickness corrugated steel plates, sometimes 8mm as required. The bottom plate is normally 8mm, sometimes 10mm as required. 3 runner oilfield tank skid with 250mm porch on both sides.

However the above mentioned specs could be varies for different tenders.

It is always being good to have duplicated orders from client, this implies a lot. Just as our own regular decisions, if we are not pleased with some products, we will go for another one. There are too many alternatives, this is the third drilling cuttings dryer system for this identical client. As we know, Russia going operation normally under cold weather, this need the gear to specially designed for cold weather.

As the first and most important solids control equipment in a complete solids control system, the shale shaker is used to separate out the most amount of solids cuttings from the drilling rig. How to define a good shale shaker? We have following suggestions:

1. A suitable and adjustable G-force range. In most cases of solids control systems, the vibration G force is from 5.0 to 7.1, the larger G force is, the better separation performance does the shaker serve. But the actual G force is decided by the mud condition, and the jobsite operator should choose and adjust the G force of the shaker. GN Solids Control has several models of shale shakers, including the single deck ones and double deck ones, and for single deck ones, there are 3 screens and 4 screens available. And all GN shakers’ G force could be adjusted by changing the positions of the two eccentric block in the 2 vibration motors, the largest G force could reach 7.5G.

2. Stable performance vibration motors, it is true that the worldly wide international brands have the better reputation because of the quality. GN Solids Control has a long term relationship with the Italy Brand OLI for vibration motors. The standard Ex Standard GN have is EXdIIbt4, while GN also has iEC EX and ATEX EX vibration motors for option.

3. A strong shaker deck whose angle could be adjusted. A strongly made structure of shaker deck is to insure the shale shaker could bear the fierce vibration G force from the motors, while the adjustable design enables the shaker could be used in different conditions of drilling mud. When you need the drilling fluid to stay longer on the shale shaker screens, you make the screen deck to have larger angle. GNZS series screens has deck angle ranging from minus 1 degree to five degrees

A screw conveyor is also called as auger, because of the screw inside the long case used for transporting the material from one place to another, it is called screw conveyor. It is common equipment used in oil and gas drilling solids control system and waste management systems, but among many suppliers, how to choose a suitable screw conveyor for your project?

What factors should be considered when choosing an Auger/ Screw Convyor?

1. HSE is always the first factor to consider for a responsible client. The design of the screw conveyor /auger is human oriented or not is very important. Are all rotating parts well covered? Do the screw conveyors /augers have the protecting cover? GN Solids Control is a company who is HSE certified and GN’s auger is accepted by many international famous companies who have strict HSE standards.

2. the material used for the screw conveyors /augers, especially the impeller. Because the drilling cuttings are of highly hardness, and they may easily damage the impeller if the impeller is not strong enough. GNSC series screw conveyors /augers use 16 Mn as impeller material.

3. the flexibility when using the screw conveyors /augers. Because the layout of each project is not the same, the client or end users have to re-arrange the existing equipment a bit to the requests of each project. If the distance is not same, which is always the cases, they need to reduce or add the screw conveyors. GNSC series screw conveyors could meet such demand easily because GN’s screw conveyors are designed as 12ft long for each section, and the first section is with the motor while the last one has the gearbox, besides those 2 sections, other middle sections could be easily interchangeable. It means, you can use more or less sections of conveyors to achieve different requested distances.

The solids control system could eliminate the large solid particles within the drilling mud to reduce the particular solids content so that to guard the transferring pump which used to transfer the mud back the rig with regard to reusing. GN just done one set mud solids control system with VFD decanter centrifuge for gold mining project in Southeast Okazaki, japan. This system is a 3 stages separation design model; the equipment configuration is as beneath: 1 . Shale shaker unit GNZS594E-HB used for coarse strong particle separation. This shale shaker unit could also be employed as a high G pressure drying shaker with variable G force up to 7. 4-panel screen makes a bigger area for drying the actual drilling mud. 2 . VFD design decanter centrifuge device used for fine solids splitting up. The first one unit centrifuge goes at a middle speed to eliminate most of the solids to reduce the particular gravity. The following second system VFD control centrifuge might run at a high speed to get rid of the ultra fine solids to make the drilling mud cleaner.

3. Screw pump set up to transfer the mud to the centrifuge. Horizontally put in at the flank of the tank, it helps to tank leading more space for operation mobility. 4. Mud catching tank used as sand snare and active mud safe-keeping. This system is to get rid of the solid particles in the going mud to make the drilling essential fluids reuse. After the solids currently being removed, the fluids may be pumped back for recycle and the pump would be additionally protected as there are less solids particles. Mud solids control system is very common merchandise and solution that GN provides. For this purpose, GN might provide separation system intended for oil drilling, no drill down drilling project and some different industrial solid and chemical phase separation.
