API SHAKER SCREEN

GN Hi-G Shale Shaker and GN Vertical Cuttings Dryer for Shell
GN Solids Control has provided many sets of solids control equipments and drilling waste management systems to worldwide clients. These years GN has gained many successful experiences in drill cuttings managements systems.
Take one tailored set of drill cuttings managements systems for Shell as an example. This system is combined with one shale shaker in linear motion and vertical cuttings dryer work under vertical G force. For this cuttings management system, it can move in the linear motion and vertical motion.

This system mainly including:
1. GN Cutting Dryer
GN930C-VFD can treat drilling waste 30 T/H to 50 T/H, the effective treating capacity is around 35 T/H. Rotating speed is adjustable with 900 RPM. Now GN cuttings dryer is the only one in China can handle OBM and WBM at the same time. GN cuttings dryer can handle with synthetic base mud. Now GN Solids Control manufactures about 60 sets of cuttings dryer every year.
2. GN shale shaker
GNZS594HGE-LD shale shaker is especially designed for drying cuttings. The vibration G force is upto 8 G when working.
3. GN mud tank and pumps
Here we use two mud tanks, the shale shaker and cuttings dryer can be fixed in these two mud tanks separately. There are some other auxiliary parts such as feed pump and flush pump.
The working process of this system:
All the drilling cuttings must be separated by shale shaker in advance, then these solids will be transferred by screw conveyor to GN cuttings dryer. By using GN cuttings dryer, most of the fluids will be separated out. The screen opening of our cuttings dryer is about 0.25mm to 5mm. Then the fluids will be feed to GN H-G shale shaker, here it will make the further drying work.

Sometimes, the drilling fluids can be sent to GN H-G shale shaker directly without the vertical cuttings dryer. However, in order to reuse the drilling fluids, all of the above fluids from vertical cutting dryer or H-G shale shaker must be treated by GN decanter centrifuge. Only in this way, we can get separated the solids that larger than 5 microns.

Mud Recycling System for Core Drilling and CBM Drilling
GN Solids Control has provided many sets of mud recycling system, some of these solids control systems are designed and manufactured on customers’ particular demands.
Take one set of mud recycling system as an example, GN has provided a double function solids control system for core drilling and CBM (coal bed methane). Usually, there are large differences between core drilling mud system and CBM mud system due to these two drilling methods needs different amounts of drilling mud.
For core drilling, the mud system is usually has the treating capacity of 50 GPM, while for CBM drilling, the treating capacity of mud system is reach to 500 GPM.
And the separating demands of core drilling and CBM drilling is not the same, either. Generally speaking, the diameter of solids from core drilling mud system is less than 20 microns; on the other side, the solids’ diameter is usually larger than 20 microns.
This mud system including the following equipments:
1. Mud Cleaner：
GN mud cleaner is composed of dual layer shale shaker and desilter. The type is GNYZ 703E-8N, it has 8 hydro cyclones which are made of PU.

2. Mini Decanter Centrifuge:
The type is GNLW223. It is one baby decanter centrifuge that is designed especially for diamond core drilling.

3. Feed Pump:
Using Nemo pump to feed the decanter centrifuge, this pump is a positive displacement type which can avoid agitating when feeding. There are also some other centrifugal pumps that used to feed the desilter, as well as some pumps worked together with mixing hopper on mixing tank.
4. Mud Agitator:
For the mixing compartments, there are several mud agitators located on the tank, GN mud agitator is one cost-effective type for mud agitating.
5. Mud tank:
Here we use one mud tank with the length of 8m. All the above equipments can be fixed on this mud tank.

GN Solids Control Co. has developed many different types of solids control equipments that can be used on oil and gas industry. And GN is a very large company who can provide turn-key solids control or waste management systems for global clients.
As we all know, the oil in Canada is mainly exists in oil sands which is also called tar sands. According to the latest survey, more than 98 percent of the oil sands and conventional oil are in Alberta. If we just considering the oil reserves, then Canada would be the third largest oil country.

                           GN Vertical Cuttings Dryer
For conventional oil, there about 39 percent in Alberta, we have already known that explore and produce oil from this conventional energy. GN has provided many sets of turn-key solids control systems for world clients. Until now, COSL has used four sets of GN 1000 GPM solids control system. And GN has also provided four sets of 1000 GPM mud recycling system for Russia client.
So for this conventional oil, GN has a large room to cooperating with drilling company from Canada. And for the oil sands, depends on the exploring and producing processes, GN Solids Control can provide different equipments.
There are two ways to explore the oil sands:
1. The first way is using excavators, the surface oil sands can be can be dig and transferred to a truck, and transported to a treating and refinery factory. This cost of this way is relatively low, but the damage to lands is very large.
2. The second method is called “SAGD”, which means steam assisted gravity drainage. The other processes are quite the same as explore the conventional oil.
GN Solids Control equipments and drilling waste management systems can help to get the bitumen and protect the environment at the same time. Many solids control equipments such as decanter centrifuge, cutting dryer can be provided by us. And we also have mini decanter centrifuge, which is especially suitable for core drilling or diamond drilling.

GN Mud Guns for agitating
GN Solids Control is one of the largest companies in China to provide turnkey solids control solutions in oil and gas industries. During the past years development, GN Solids Control has already become a world famous brand in the solids control field. With the development of GN Solids America LLC and GN Solids Russia, GN will have the chance to service more and more clients, and right now GN solids control and drilling waste management systems have already been used in over 60 countries.
GN is a company that can provide whole solids control project to customers, and on the other side, GN Solids Control is manufacturing various kinds of spare parts such as mud guns, centrifugal pumps, shear pumps, submersible pumps etc. Some of these spare parts are sell very well, and after the clients have used GN solids control spare parts for a while, they come to GN for turnkey solutions because they already have the confidence about the excellent quality of GN solids control and drilling waste management systems.

Today we would like to give you a short introduction about GN Mud Guns. As we all know, GN mud guns are used for flush the corners of the fluids in mud tanks, and they are usually working together with mud agitators. When a mud agitator is keep the solids rotating in mud tank, the mud gun can help to work on the corner due the large working pressure.
There are two common types for GN mud guns, one is a fixed type (which means the mud gun is fixed on a mud tank and can only work for the specific angle), the other type is a rotating one, the mud gun can rotating by adjusting the hand lever on the top. Usually, we recommend customers to use rotating type, although it is a little expensive, it is quite convenient to use. The working length of mud gun shaft can be decided by the height of tank.

A total drilling rig system usually contains drilling floor block, mud solids control block and recovery, mud pump and power block. Concerning these, the mud solids control and recovery block is composed of drilling mud recycling and drilling waste cuttings system. This block can be used to maximally recover the valuable drilling mud as well as decrease the waste discharge. 

The drilling waste cuttings management system occasionally called the further treatment method for solids control. Since the cuttings was delivered from out interface of the primary solids control equipment like shale shaker and mud cleaner towards the cuttings dryer device. The principal equipment for drilling waste cuttings recovery consists of cuttings transferred equipment, Verti G cuttings dryer, feeding pump and decanter centrifuge.

The cuttings transferred devices is being regarded as a bridge connecting the primary solids control system to the waste management unit. The typical and well-liked approach to transfer the cuttings is to utilize the screw conveyor and hose pump.

What is the Difference of the screw conveyor and hose pump

The screw conveyor itself has a gathering groove and the screw propeller push the cuttings to the Verti G cuttings dryer. Since the screw conveyor is engineered to shift the cuttings around an upright line. Usually, on the spot, there are not just 1 unit screw conveyor, several unit screw conveyors are situated crossing with certain angles so as to the waste cuttings can be delivered to the cuttings dryer. While the cuttings dryer feeding port is high, the screw conveyor is sloping. Subsequently if the waste cuttings are high liquid content, the liquid might be regurgitate and overflow off the conveyor.

The hose pump is a new, multifunction and multipurpose industrial pump. There is a particularly made rubber hose with smooth inside and high strength installed in the pump body. The hose pump has a exclusive structure with no sealing aspect, no leakage and no pollution. It has a high suction capability, self-cleaning capability, sucking material in two instructions. The hose installed in quite simple and operation is effortless, and the maintenance charge is low. The most essential is no block when pumping fluid with high viscosity and foreign substance content.

The drilling waste cuttings transferring equipment is important throughout the operation. GN Solids Control has applied both of the screw conveyor and hose pump in the design of the drilling waste management system, for more information and facts, please get in touch with GN freely.

GN Screw Conveyor
As the established of GN Solids America, GN is beginning to known as a famous solids control company from China. And with the excellent quality and good performance, GN solids control equipments are welcoming more and more clients in North America to our Houston warehouse. Some clients prefer to see these solids control equipments first and rent for trial use.
We believe as the days went on, GN will become a leading company in solids control and drilling waste management in the sooner future.
Today, we would like to give you a brief introduction about our screw conveyor (which is also known as auger). GN Solids Control has provided many sets of screw conveyors every year for worldwide customers.
For the screw conveyor, it is mainly used for transferring mud or solids, when it contains too much water, we don’t recommend using conveyor.
GN has some different types, from conveying capacity 20 tons per hour to 45 tons per hour. All these capacity can fulfill the general demands of mud transfer.

Sometimes, we have one screw conveyor with V type collection box. There are some flanges with pipes on the V type collection box. This kind of screw conveyor is especially used for oily sludge transfer. The quantity is different due to the length of screw conveyor.
Flanges and pipes on the V type box are used for providing hot steam, so the oily sludge can have a good flow ability. There is also one beam across this conveyor, it is used for distributing oily sludge to the two ends.
There is also one type of screw conveyor with heating system, which is equipped with pipes under the cylindrical part of conveyor. And this type is mainly suitable for cold environment. Lately, we also provided some set of these screw conveyors with heating system to Russia clients.

GN Solids Control Co has been working on solids control equipments and waste management systems for many years, and many clients are keep purchase these solids control equipments from GN every year due to the excellent quality and rest assured after sales maintenance.
Recently, GN Solids Control Co has provided many sets of solids control equipments for our client in Kuwait. This client has purchased GN equipments for th

eir work over drilling rig. When we cooperate with client at the beginning, we showed our willness to have a win-win cooperation by providing solids control equipments with good quality.

For the shale shaker, we designed and manufactured a mud distributor for two sets of shale shakers, here we call it dual connection GN shale shaker. So our client has 4 groups Dual Shaker, which has a very large treating capacity, because even one set of GN shale shaker can treating the drilling fluids upto 616 GPM m³/h.
Based on the above solids control equipments, it is obvious to know this is a three phase solids control system that our client wants to use.
1. Shale Shaker
GN shale shaker can separate solids to 100 microns. For this type of GNZS594, the dimension of shaker screens is 585mm X 1165mm, so the screens are replaceable with Swaco Mongoose screens.
2. Vacuum Degasser
The mud come from shaker will be sent to vacuum degasser to eliminate the air in drilling fluids. By using GN vacuum degasser, the drilling mud can be kept in a steady viscosity.
3. Desander and Desilter
GN desander and desiler can separate solids to 20 microns. The cylones on desander and desilter are all made of PU, which is really helpful to have a long time lifespan.

Recently, GN Solids Control(www.gnsolidscontrol.com) has manufactured a set of mud system for geothermal drilling, which will be delivered to Kenya. GN is specialized in designing and building up solids control system for oil and gas drilling, mud system for geothermal drilling, mud cleaning system for HDD drilling and tunneling. With its high quality and strict quality management standards and systems, GN has been the first API certified solids control company in China. This week, from Monday to Thursday, the customer visited GN factory for inspection. The testing was successfully finished, showing that the mud system performs well, though there were modification requirements posed by the customer. But before delivery, this system should be PVOC certified.

The full name of PVOC is Pre-Export Verification of Commodity. It is inspecting standards required by KEBS for exporting commodity to Kenya. If the commodity listed in PVOC content is inspected to be in compliance with PVOC, COC (certificate of commodity) will be issued for custom clearance; otherwise, the commodity will not be allowed into Kenya. GN mud system for geothermal drilling belongs to the catalog listed in PVOC, so COC is required for export; otherwise, GN mud system will not be allowed delivered to Kenya.

While the customer’s visit, we are also preparing documents required for PVOC. It is the first time we do this, so it is a little confusing and tough for us. But, with the help of an agent for PVOC, we finally summit the documents in this week, and it has been approved. The next step will be inspection of the commodity, it will happens last week. And is we get through the inspection, we will get the COC. Then GN mud system will be delivered to Kenya, and go into Kenya.
