Africa, is a mysterious land to many people’s eyes. But the Oil and Gas linked GN Solids Control to the African countries via the good quality solids control and waste management equipments and responsible service of GN commissioning team. These 10 sets of GN Decanter centrifuges are ordered by a large African drilling company, they are ready for dispatch now and will be shipped to Africa in recent days.
GNLW363 is most popular product of GN. 14 inch bowl diameter decanter centrifuge is most popular size internationally, because: 1. the treating capacity depends mostly on the bowl diameter, and such treating capacity could meet most applications. 2. In order to get a good drying result, the length-diameter ratio is better at 3, and the cost for a 51 inch bowl length is of more cost-effective during production.
GN’s advantages in this model: for the same bowl diameter and specification of centrifuge GNLW363, GN Solids Control provide 4 options: 1, Economic solution: GNLW363CD, fixed speed, 2. Economic solution: GNLW363CD-VFD, vfd control panel. 3. Highest solution: GNLW363CG, fixed speed, 4. Highest solution: GNLW363CG-VFD. Customers could choose any of them per the jobsite need or per budget.
GNLW363CG series decanter centrifuge: it is not only the highest GN standard centrifuge, but also, it is highest international standard centrifuge in solids control field. See what material GN chooses for this centrifuge: SS2205 for rotating bowl, SKF bearings, easily adjustable liquid level ports, most anti-wearing tiles on impeller and etc.
Customers could choose per their jobsite condition fixed speed one or VFD control panel. In case of VFD control panel, the working speed could be easily set from 0 RPM to 3200 RPM. In case of fixed speed, it doesn’t mean only 1 speed only. Customers could choose 2 extra pulley and belt for another 2 operating speeds, in order to be suitable for different applications.

GN Solids Control is not only professional solids control equipment supplier, but also supply different mud tanks for different functions. The size of mud tanks range from big mud tanks for oil drilling solids control system and mud plant to mini mud tanks, eg trip tank, sump tank, pill tank etc.
1) Pill tank and trip tank for solids control mud system
Pill tank is used for conditioning the drilling mud by add barite, bentonite or other heavy weight additive. The size is about 1000x1000x1500mm. The position is placed after decanter centrifuge, fixed on the mixing mud tank. After adding heavy weight additive, the drilling mud can be mixing fully by force from Jet mud mixer with a centrifugal pump.
Trip tank is used for feeding the well when change the drilling tubes. It is generally positioned besides the shaker tank.

Why we should have drill slurry storaged? Mainly it is because of the reasons below:
(1) Requirement for the carriage and storage of mud on mobile drilling units has increased over the years, it is not convenient to process the drilling mud at the platform, you have to collect the used drill slurry and carry it to drilling fluids plant for process, then recycle the clean drill slurry and disposal the useless cuttings, so that it will not influence the environment.
 Drill Slurry Storage (2) Clean drill slurry should be storaged for use, for drilling , for mixing , for lubricate the drill bit.
(3) Useless drill cuttings should be collected and storage, then carried to drilling waste management system for process.
GN solids control manufacture drill slurry storage tank for various application, with necessary mud agitators, mud gun, centrifugal pump and mixing hopper. We can produce mud storage tank together with solids control system or separately. Compared with shaker tank and intermediate tank, the pipeline of storage tank is much simple, if required by the clients, we will divide it into several compartment by clapboard. Sometimes mud ditch is installed on each compartment. Handrails, stairs, cleaning gate, valves are included, but walkways are not included. There is flexible hose connected 2 tanks.

Mainly there are 3 types of drilling fluids, water-based mud, oil based mud & synthetic based mud.
Synthetic-based fluid is a mud where the base fluid is a synthetic oil. This is most often used on offshore rigs because it has the properties of an oil-based mud, but the toxicity of the fluid fumes are much less than an oil-based fluid. This is important when men work with the fluid in an enclosed space such as an offshore drilling rig.
There is a technical limit to what can be achieved with water-based fluids, especially in the short and medium terms. For this reason, I believe advances in the environmental performance of synthetic-based fluids can be expected to occur faster, in combination with improved treatment and new drilling techniques. But synthetic based mud’s cost is much higher than water-based mud.
The mud recycling system for the 3 types of mud is basically similar but has little difference.
 synthetic based mud recycling system Synthetic based mud is mostly used for offshore drilling, people sometimes do not process and recycle the used mud at jobsite, they have the used drilling fluids in mud pits and transport them to a drilling fluids plant or factory for recycling and treatment, then ship back to the rig. In some other situations, they have the solids control system at jobsite, but no drilling waste management equipments at jobsite.
Water based mud is with cheaper cost and also environment friendly, it is mainly used for land drilling, in most oilfield in China or some developing countries, water based mud is widely used, and it works well with solids control system produced in China.

Drilling fluid is used to aid the drilling of boreholes into the earth. Often used while drilling oil and natural gas wells and on exploration drilling rigs, drilling fluids are also used for much simpler boreholes, such as water wells. Liquid drilling fluid is often called drilling mud.
In drilling operations, solid weighting materials are commonly added to the drilling fluid to give sufficient density to the fluid to hinder inflow of oil or gas into the wellbore from the down-hole formation. Weighting material sag. i.e. sedimentation of weighting material from the drilling fluid, has been and is currently one of the biggest challenges within the drilling fluids industry as it can lead to well control problems, lost circulation, hindered running of casing/liner, insufficient displacement etc.
 weighting material adding equipment CALCIUM CARBONATE is Acid souble weight material.It is used to prevent fluid invasion of permeable zones, and to prevent loss of circulation during drilling, workover, and completion activities. CALCIUM CARBONATE is applicable in all drilling fluids, aqueous and non-aqueous. It can be used to prepare a pill for spotting purposes. is also used as an acid soluble weighting material for drill-in or workover fluids with a density of 14.0 ppg or less.
HEMATITE is for extremely high density mud.It is used to obtain mud weights in excess of 20.0 ppg in water based drilling fluids, 19.0 ppg in oil based drilling fluids, or any time that exceptional control is required of solids percentage for rheology control.
Barite is the most used weighting material, has a density of 4.1. It is used for increasing the density of fresh water, salt water, and oil based muds.
Barite is added through a hopper, GN designed Jet mud mixer is used for barite adding, it consist of venturi hopper and mixing pump. It can be used with the complete mud system, also it can be used separately.
Jet shearing unit is consist of venturi hopper and shearing pump, which can cut the big section into small pieces and add weighting material then mix them. It is commonly used in oil & gas drilling solids control system, usually it is installed on the weighting tank or mixing tank. Sometimes it is used together with decanter centrifuge.

GN decanter centrifuges are widely used in complete drilling fluids recycling system, work together with cutting dryer. Such drilling fluids circulation system is widely used in Venezuela and other South American countries.
Venezuela’s proven oil reserves are among the top ten in the world. Today, Venezuela is the fifth largest oil exporting country in the world with the second-largest reserves of heavy crude oil (after Canada).
 drilling fluids decanter centrifuge There is big demand of oilfield drilling mud system/solids control system in Venezuela. Before they mainly purchased the drilling mud system from USA . But now more and more clients realize that they can purchase rig packages from China, although the delivery time and transportation will be longer and complicated, they can save a considerable drilling cost.
A complete drilling fluids circulation system including shale shaker, mud cleaner( or separate desander, desilter), screw conveyer , Cutting dryer, recycling mud tank, decanter centrifuge(with feeding pump), drilling mud reserve tank/storage tank, etc.
After processed by cutting dryer, the large drilling cuttings have been separated out, the drilling fluids flows to recycling tank or to decanter centrifuge through screw pump. Since decanter centrifuge has higher separation factor than cutting dryer, it can separate fine particles from the drilling fluids and recycling barite to keep the drilling fluids balance.
