GN Centrifuge for Barite Recovery and Dewatering Application

Leave a reply

Not matter you are looking for a barite recovery or for a dewatering application, GN is capable of supplying the most of reliable and durable centrifuge for your project. GN centrifuges are used in all over the world for oil & gas drilling, waste management process and other drilling purpose.

Barite Recovery Application

First of all, Barite is a heavy mineral having a specific gravity of 4.5 and its main use is in the manufacture of oil based drilling fluids. It will increase the density of drilling fluids that is reaching a desired depth in the drilling oil and gas project. The cost of barite is really high. Therefore, drilling contractor need recovery the barite and subsequently mix in the active drilling fluids to ruse it. On the other hand, most barite is less abrasive than other material and cause little damage for the drilling equipment.

GNLW452 is one kind of centrifuge which effectively recovers maximum barite to achieve the economic goal. GN centrifuge is 18 inch diameter and 43 inch length which can effectively process 176 gallon/minute drilling fluids. Single motor driving 60 HP offers a small footprint and easy operation. 2205 or 304 duplex stainless steel assures high quality of equipment. IECEX and ATEX international explosion proof standard provide a safe working environment. Also, Competitive price and reliable working performance win a really good reputation in the solids control industry.

Dewatering Application

GN supply ranging 14 inch, 18inch to 22 inch bowl centrifuges for different requirement of capacity. Both Fixed speed and VFD (Variable Frequency Drive) are available for different requirement. GN dewatering centrifuge is capable of removing ultra fine particles that cut point is down to 2~5 microns meet and exceed with most customer’s expectation.

GN centrifuges will continue to obtain high demand as the solids control industry requires sophisticated operation and high environmental regulations. Contact with us for more information.

How Are You Gonna Choose the Shaker Screen, Shale Shaker and Mud Cleaner

Leave a reply

There is certain information that you may require so you could make a wise decision and before you sign the check on buying a host of item.

Factors

Screen: Generally, the more screen surface area you apply means more volume of drilling fluids you can clean.GN provides two panels, three panels and four panels for processing different volume of drilling fluids. In addition to the surface area, the API standard of screens is measured by the amount of holes per square inch on the panel screen. Different API number of shaker screen controls the size of cuttings that you remove. Sizes will change replying on the size of the cuttings and the type of formations you are removing

Shakers: There are three kinds of shakers in the market including orbital, elliptical and linear motion. GN provides the most reliable linear motion shale shaker. Technically, linear vibration is generated by a pair of eccentric motor turning in opposite directions. The design is able to allow for the development of straight line or linear motion that can also be produced in a positive incline. Therefore, linear shaker is capable of processing heavy clays, debris, small particles and ultra-fines. 3C (1)

Hydrocyclones: In order to further effectively remove ultra-fine solids the hydrocyclone size may either be 4, 5, 10 or 12 in. The smaller cone you have the ultra-fine solids you will clean. Each size cone has the corresponding micron cut point. GN 4 inch cones have a micron cut of 20 microns and the 10 in. have a 40 micron cut. Each 4 inch Hydrocyclone cones process the drilling fluids at a rate of 50 gallon/minute. Each 10 inch Hydrocyclone cones process the drilling fluids at a rate of 500 gallon/minute.

Mud Recycling System for HDD Rigs

Leave a reply

Generally, trenched will be excavated for pipe laying or conduits and cables installing. While, in some case that trenching is not practical for geographic factors or environmental reasons, directional boring, usually known as horizontal directional drilling(shortened as HDD) will be applied. HDD is a typical example of trenchless technology which means using a surface-launched Drilling Waste Management to bore a path for installing infrastructure such as pipelines, gas lines, oil line, sewer lines, water lines, power cable conduits, and telecommunication. HDD is normally applied when a river, road, landscape, or a congested place needs to cross for pipe and cable laying. Until now, installation length by HDD has been up to 2000 meters, and diameters up to 1200 mm have been finished in short length. Yet, that does not necessarily mean that HDD can be adopted for all road-cross or river -cross drilling. Actually, solids rock or sedimentary rock is the most suitable material. HDD is used instead of other techniques mainly for the following benefits. HDD not only makes traffic disruption less and deeper or longer installation possible, but ensures a lower cost and environmentally safer.

GN Solid America is specialized in design and build up mud recycling system for HDD rigs, and for a decade’s innovating and evolving, GN’s mud system is widely used in Australia, India, and other countries for HDD rigs. The below features are proof of GN’s mud systems popularity. Firstly, GN provides compact design with a combination of mud cleaner and underflow shaker, which is double deck for the first stage separation and drilling mud’s drying.

Secondly, GN supplies a full range of mud system:150/ 350/ 800/1000/1500GPM.

Thirdly, GN offers cost effective equipment integration from a single source: GN Solids Control factory.

Primary Safe Unit for Drilling Fluids-Mud Gas Separator

Leave a reply

We could see the mud gas separating installed in many drilling rig jobsite. Regarding to complicated geologic environment of drilling site, mud gas separator is used for separating the hazardous gas from the drilling fluids. Mud gas separator not only is used for oil & gas drilling site, but also it is applied for the deep mining drilling jobsite.

How is GN mud gas separator working?

The drilling fluids/mud from down hole goes into mud gas separator (poor boy degasser).Due to the gravity force, the mud drops down on the 1000mm diameter vessel of poor boy degasser. Mud collides on buffer plate of pipe so the dangerous gas will be relieved from the drilling fluids. Obviously, gas flows to the top of 8 inch vent line which is connected with the flare igniter to burn out. Normally, flare ignition device is about 160 ft away from the poor boy degasser to assure the safe distance burning. Meanwhile, the mud would go down and accumulated at the bottom of mud gas separator, and subsequently flow to the into the solids control system including shale shaker, desander, desilter and decanter centrifuge etc

Why we choose GN mud gas separator?

1.GN is recognized world-wide for accuracy, durability, from easy to complex and standard to customize in order to design and manufacture the most reliable mud gas separator .

2. GN design, application, and manufacturing engineers have designed custom products to fit every single application. Such as, we could horizontally fold the mud gas separator on the skid for easy transportation.

GN provide the economic, environment and safe closed loop system including mud gas separator, shale shaker, desander, desilter, mud conditioner, vacuum degasser and decanter centrifuge
etc. We not only just provide you a single unit or system, but also focused on the best solution for your mud, fast response and convenient spare part delivery. Call us today to save your time and money.
