GN Drilling Waste Management for OBM and WBM Treating

Leave a reply

GN Solids Control has been designing and manufacturing many sets of drilling waste management systems for global clients. Now GN solids control and drilling waste management equipments are exported to over 60 countries.
GN Drilling Waste Management systems can treat oil base mud, water base mud. It’s obvious to know, in order to get a better separating performance we need to treat the oil base mud and water base mud separately. GN waste management systems are composed of cuttings dryer and decanter centrifuge.
The largest advantage of GN cuttings dryer is it can treat with OBM and WBM. For some drilling rigs, in the primary drilling period most of the fluids are water base mud, the oil based mud will be used as the rig drilling much deeper. So only buy one cuttings dryer, you can use it for all the drilling process.
Now many large clients are using GN drilling waste management systems, such as Shell used one whole unit to separate the OBM in the shale gas drilling process. And Baker Hughes is using 4 sets of drilling waste management systems to do their drilling work in extremely cold environment.

According to the survey made by Shell, oil in the final cuttings treated by GN cuttings dryer will be around 5%, and it will be reached to 3.75% when you feeding with few drilling mud.
Now GN has upgraded our cuttings dryer to the forth version: the rotating speed can reach to 1200 RPM, separating performance is better than the third version. For the decanter centrifuge, GN engineers also gave some creative and practical modifications: mud is feed to the large end of the rotating bowl, some outlets on the screw propeller is added, one flexible bow is fixed on the solids discharge port to avoid block etc.
The standard GN drilling waste management systems can treat with much more solids with a satisfied performance. For further details, welcome to contact us freely by thomas@gnsolidscontrol.com.

Different Usages for GN Cuttings Dryer and GN Hi-G Shaker

Leave a reply

GN Solids Control manufactures 60 sets to 100 sets cuttings dryers every year. It can be used to separate OBM or WBM. Usually, in order to save cost the Hi-G shaker will be a replacement solution to separate the WBM, while the cuttings dryer can be used to treat OBM.
For the cuttings that separated by shale shaker, mud cleaner, it contains around 20% oil. Then these cuttings will be feed into the cuttings dryer. If we use GN High G Drying Shaker, normally we can get the oil on the cuttings around 10-12%. But if we use GN cuttings dryer, we can get the oil on the cuttings to be 3-5%. For every 100 Tons drilling cuttings, without using TDU to heat the drilling cuttings, our clients can recycle additional 7 Tons oil.

The treating capacity of GN vertical cuttings dryer is around 30~40 Tons/H. Solids that larger than 250 microns will be separated out, while the smaller size solids will be left in the drilling fluids.
The wet material enter the TDU will reduce the capacity dramatically as we know. The solids come out from GN cuttings dryer and GN Hi-G shaker can be send to TDU for further separation, but due to the oil in the cuttings is not the same ( 3-5% OOC cuttings after treated by GN cuttings dryer and 10-12% OOC cuttings after treated by GN Hi-G Shaker), the difference is pretty obvious. By using the cuttings dryer, it will increase capacity of the TDU, and the electricity cost will be saved.

The wet material will also increase the load of the other unit of TDU system. Like the Vapor Recovery Unit, Cooling Tower Skid, Oil water separator etc. As we know, the capacity for TDU is very small if the material especially when the materials are very wet.
Generally Speaking, considering the TDU don’t have a large treating capacity, so the cuttings can be treated by one GN cuttings dryer, one GN Hi-G shaker. Sometimes, you also need one GN decanter centrifuge for much finer solids separation.

Mud recycling system with decanter centrifuge for HDD

Leave a reply

GN solids control new designed mud recycling system with decanter centrifuge has been used for HDD mud recovery. Normally the client did not use decanter centrifuge, but for some special projects, the solids size are very fine, the 4 inch desilter cones are not enough, they have to use the decanter centrifuge to separate the fine solids. CPP, short for China Petroleum Pipeline Bureau, is the China largest Horizontal Directional Drilling Contractor, they have bought over 30 sets of muf recycling system from GN solids control in the past 5 years. Some of their mud recycling systems are tradional design with only shale shaker, desander, desilter 3 phase cleaning , some are with decanter centrifuge because of high percentage of fine solids in the drilling fluids.

This time they bought 4 sets of 1000gpm Mud Recycling System with GNLW452 middle speed decanter centrifuge, which is one of the most reliable working, high treating capacity with separation point 5 microns.

The main features of the 4 sets of mud recycling systems are the equipments are installed in a 20ft standard container frame, and the mud tank size is replaceable with standard 20ft container, during working, they are installed with screws. And during transportation from one place to another, they will be shipped by the vehicle fit for 20ft container size. This is for fast move, fast disassembly, fast installation purpose.

Not only for the mud recycling system, we can also adopt such design into drilling waste management system design for the same reason. In some cold temperature area, you can cover some tarpaulin outside the 20ft steel frame to keep them warm in winter, so you can save the money of heating lines to keep them warm and fluxible.

If you need a similar design for your HDD,CBM, underground construction, mining project, pls contact GN sales.

As the oil price is going down, many oil companies are suffering from this great pain deeply. Some the oil and gas companies are cutting cost by various methods, some drilling companies are trying to find a more cost effective solutions for their solids control and drilling waste management systems.
Some companies might thought solids control equipments or drilling waste management systems made in China are always very cheap with poor quality. But the truth is many large manufacturers pay great attention to the quality control, one of the largest solids control manufacture such as GN Solids Control Co. and GN Solids America LLC have been exported to over 60 countries due to the excellent quality and rest assured after sales service.

Although the oil market is pretty tired, GN Solids Control Co. is getting more and more chances to win large clients for over abroad clients. In this Jan., GN has selling over dozens decanter centrifuges to one drilling mud client in Africa. Trying to find a much more reliable supplier in China might be one of the best way for continuing the oil and gas drilling temporarily, and it will be getting to known by more and more famous oil companies globally. For GN, we have provided many solids control equipments and drilling waste management systems to large clients such as Shell, Baker Hughes etc. This will be a golden chance to proven that not all the equipments made in China are always with poor quality. At least, it’s obviously to know, most of the Apple iphones are made in China. Who dare to the say the quality is not good?
And GN also has also got some large bids in the domestic market since the beginning of this New Year. Several weeks before, GN Solids Control just provided three sets of drilling waste management systems to one Sichuan drilling company. More and more drilling companies are showing great confidence to GN products.

GN Drilling Waste Management Systems
GN Solids Control has many experience engineers in waste management area. In order to meet the demands of environment protection and make money from the waste oil, using GN drilling waste management systems would be one cost effective method.
GN drilling waste management systems is a pretty standard system mainly including one GN cuttings dryer and one decanter centrifuge, two positive pumps (one for cleaning and flushing the cuttings dryer when the work is finished, the other one is used for feeding mud into the decanter centrifuge), skid and tank as well as some other auxiliary equipments such as ladders, walkways, guiderails and lights etc.
In order to operate GN drilling waste management systems conveniently, GN designers take the working conditions into consideration. The whole systems are pretty compact, while the operators have large room for work.
GN cutting dryer is quite effective for OBM, WBM or SBM treating. When using GN dryer, on one hand you can separate the solids out from the waste mud, on the other hand you can reclaim some precious oil which can be used for further treatment and sell to make profit. From this point, treat the waste oil can reach the aim of protecting environment and make money.
Solids come out from the waste mud contain a little bit oil, according to the discharge standard, these solids can be discharged directly without any further treatment due to the oil is less than 5 percent.
As to the WBM treating, GN dryer also can perform excellently. Solids usually contain less than 10% water. These solids can be transported to other places after 2 or 3 days nature dry.
Fluids come out from cuttings dryer can be sent to decanter centrifuge for further separation. All the solids larger than 2 or 3 microns can be separated out.
GN drilling waste management system can also working in harsh environment which is very cold. Last December, some sets of GN drilling waste management systems are using in Russia, where the temperature is minus 40 ℃.

GN Dredging System Mud Tank

Every year, GN Solids Control provides over hundreds of systems to solids control or mud recycling system. And GN is manufacturing about 350 to 400 sets shale shakers, 250 to 300 sets decanter centrifuges and 60 sets to 100 sets cuttings dryers.
As the fast development of GN Solids Control Co. and GN Solids America LLC, more and more companies are coming to GN for their mud separation solutions.

GN also providing various tanks to customers who are working in oil and gas, HDD, Dredging, CBM or TBM areas etc. During the past several months, GN got many inquiries on mud tanks. Some are pretty small one such as hundred bbl, while some are large mud plant such as 10,000 bbl.

For different areas, GN has customized solution for every client. Let’s take the dredging slurry mud system as an example. In order to better service the needs of dredging separation demands, GN has designed V type tank to satisfy their demands on clean the mud in the tank conveniently. Usually, there will be some mud fall on the bottom of the mud tank, and the mud can be cleaned out from the hole on both sides of the tank. Actually, this is not a easy job to do, many mud will be left inside no matter how hard you try to get them out.

But if you’re using GN V type tanks, tough thing will be just a cup of tea. GN has assembled one screw conveyor on the bottom of the mud tank, all the mud that fall off on the bottom will be conveyed by GN screw conveyor, so it will be separated thoroughly. When the separation work is finished, you can stop all the shale shakers on the bottom and start the screw conveyor to get the mud out.

GN also designed one square mud tank next to the V tank. The square mud tank can help to enlarge the capacity of this dredging system

Decanter Centrifuge buying guide

Leave a reply

Decanter Centrifuge is the machine that use high rotating speed in gravity force to separate solids from water. The decanter centrifugeis also able to separate two liquids that differ in density as well if higher rotating speed is reached by more powerful motor which can produce higher RPM. Depending the RPM of the decanter centrifuge motor, it can produce the rotation force in 1000 times and beyond on normal gravitational force. The separation time need it from minutes to hours. The bowl tube that equip with internal conveyor rotate in extreme high speed that moves in same direction but at different velocity to achieve solids separation from liquid. Many industry such as oil and gas field, food processing field, chemical plant and environment treatment company are using decanter centrifuge. The only difference between these industry choosing decanter centrifuge is material in the rotating bowl. When choosing a decanter centrifuge, ensure wetted parts that makes contact with treat subject are made with high quality of steel. Decanter centrifuge use to treat chemical and subject that will cause corrosion like drilling fluid in oil and gas industry, the metal need to choose forged titanium or haste alloy. While food process industry, it is need to be aware of polished stainless steel because of buildup of bacteria.

Other factor need to consider while choosing decanter centrifuge is treating capacity. This is the volume of treating subject the centrifuge can process per minute. It is refer GPM (gallon per minute) since the purpose of decanter centrifuge is treating liquid to separate solids from it. Decanter centrifuge treating range can be from 5 to 1000 GMP. Another capacity to consider is the motor that drive the bowl, which can be range from 25 hp to multiple hundreds hp. If buyer is considering used decanter centrifuge, it need to know the prior industry and usage. This consideration is to avoid contamination, corrosive and hazardous material. Used vendors often offer immediate installation and aggressive pricing which is advantage for time and price sensitive projects.

GN solids control equipment is mainly used for oil & gas drilling application. Our equipment effectively removes the solids from drilling fluids and maintains the mud properties. Recently, we have completed 3 sets of completed solids control equipment for European oil & gas drilling industry including conventional shale shaker, mud cleaner, decanter centrifuge, mud agitators, mud guns and centrifugal pump etc. This solids control system is matching with 100HP drilling rig.

Why Choose GN Solids Control system?

1. In solids removal, shale shaker is an economical option with minimal maintenance requirements and simple design. GN’s shaker employs a linear motion technique resulting in longer screen life and solids discards.

2. GN provides mud cleaners in low profile and standard arrangements. Each unit comes with 10” desander and 4” desilter hydrocyclones, and GN mud cleaner maximum reduced solid waste and increased drilling fluid recovery.

3. GN vacuum degasser is capable of separating all the hazardous gas maintaining the mud properties and density. Vacuum degasser is widely used in the oil & gas drilling application. Also, GN degasser works as a big blender for the drilling fluids contribute to the treatment of desander and desilter

4. Decanter centrifuge plays a vital role in the solids control system. There are two main advantages in the solids control system. Foremost, centrifuge will maintain the mud properties and remove all the fine solids. On the other hand, it will recovery the barite for reusing purpose in the active mud.

5. Regarding to the mud mixing and storage system, we are also able to supply the mud agitators, mud guns, hopper and centrifugal pump etc. GN mud mixing system has the capabilities to mix all kinds of chemical achieving the balance mud properties
