GN Solids Control just exported to mud cleaning system to European, which including shale shaker, mud cleaner, centrifugal pump and jet mud mixer

Mini Solids Control System

1. One set of GNZS752E-DM shale shaker with two panels shaker screen.710mm low weir height is easily for cutting transport to shaker

2. Desilter consist of 4 desilter cones and one set GNZS752E shale shaker, which is small capacity

European market has really high standard and stringent rules for the oilfields equipment. However, GN has proved our equipment quality to the world again. GN is the first API certification solids control equipment manufacturer in China. Also, GN Solids America LLC is the first USA based solids control company from China, with branches in USA, Australia, Latin America, and Middle East.GN has exported waste management equipment over 60 countries. All of the results showed us that GN is striding to world and service different country.

In the future, we will be based on the high quality, fast service and convenient spare parts to service the world. Our client is very satisfied with our equipment, and cooperation will be continued between us and European buyer

As one of the top Solids Control Equipments manufacturer in the world. GN offer a compelte line of solids control equipments and some drilling waste management equipments for the oil/gas industry.GN developed Vertical Cuttings Dryer has been proven to provide a dramatic reduction in drill solids waste discharge and to help reclaim the oil-based fluids or synthetic based fluids from cuttings.

Vertical Cuttings Dryer

Vertical Cuttings Dryer

The high-capacity GNCD930 Vertical Cuttings Dryer is a screen-type centrifuge which designed for the continuous feed and efficient throughput necessary for drilling operations.Convenient access to normal wear parts helps simplify maintenance and minimize unit downtime.

Setting Up Cuttings Dryer Operations

Successful Cuttings Dryer operations are not as simple as installing and running the cuttings drying equipment. The fluids recovered by the dryer usually contain high levels of low gravity solids that can cause significant problems if returned directly to the drilling fluid system. GN not only can offer Cuttings Dryer,But also Decanter Centrifuge, Screw Pump, Augor, Shale Shaker, etc.


Model: GNCD930
Feed Capacity: 30-50 Tons/H
Max Bowl Diameter: 930mm
Screen Opening: 250/350/500 Microns
Rotary Speed: 890 RPM
Main Motor: 55Kw
Oil Pump Motor:0.55Kw
Dryness Efficiency: <5%
Dimension: 2780X2080X2450mm
Weight: 6500Kg

Shortly before, a client from Indonesia told us they plan to implement a pitless drilling system in their project for disposal the unused drilling mud.

What is Pit Less Drilling System

500GPM Hydraulic Jack up solids control system

Pit less drilling system is also call closed-loop drilling system. It employ a suite of solids control equipment to minimize drilling fluid dilution and provide the economic handling of the drilling wastes.
In the pit less drilling system where a reserve pit is not required, used drilling mud are recycled, and solid wastes can be landfarmed, hauled off or injected downhole.

Typcical Pitless Drilling System include:

1. Series of Linear motion shale shaker
2. Mud cleaner
3. Centrifuges followed with dewatering system: in the dewatering system, the High speed dencanter centrifuge and cutting drier are included.

Further to our former articles on small drilling mud system we get many feedback from user and reader. They are also interested in larger system. Such as 500GPM drilling mud process unit.

Now we are pleased to give you following  information on the 500GPMP mud circulation unit


500GPM drilling fluid unit applications

Drilling fluid is widely used on various well drilling even construction. For drilling fluid, we need purification, reciculation, etc. Similar, fluid system application is also rather wide.

500GPM drilling fluid system can be used in small O&G drilling, CSM drilling, mining drilling, diamond drilling, water well drilling, geothermal well drilling, tunneling, pilling, civil construction, also horizontal drilling (HDD), etc.

We can match 500GPM system for 650HP rig. Or according to mud pump discharge rate, such as 120m3/h. This is subject to actual working condition and user’s preference.

This mud circulation unit can help drilling fluid cool down during drilling. Bring out drilling cuttings, and give lubrication application on drill bit or drill pipe. Also decrease much cost during drillings.

500GPM mud system proposal

We improved our equipments model and performance. So GN new proposal for 500GPM mud circulation unit is as following:

1. First phase, one set shale shaker should be GN703 series. Including linear motion and BEM type.

2. Second and third phase, one set mud cleaner combined with GN703 shaker, one 10″ desander cone, eight 4″ desilter hydrocyclone.

3. Then the mud tank, 9×2.3×1.8m. This is considering convenient removal and transportation including oversease shipment and domestic transit at user ending. We need a jet mud mixing pump matched with this circulation unit.

4. So we need 3 centrifugal pumps totally. Two are feeding pump for hydrocyclones on mud cleaner the other is for jet mud mixer combined with hopper.  Furthermore, jet mud mixer hopper can be mounted together with pump also can be mounted on mud tank.

There are two kinds of mud system (solids control system), closed loop mud system and Reserve pit ( not closed loop mud system) .

GN can design both Closed loop mud system and reserve pit mud system. For closed loop mud system, it is usually used for oil or gas well drilling, the drilling mud flowed from high-pressure mud flow line pipe, and reserve pit mud system is usually for Directional drilling, and the drilling mud is pumped by a submersible slurry pump. But no matter what kind of mud system, you should always remember “material balance”, the mud feeded should be finally balance with the solids disposed.

closed loop mud system

The risk factors of Reserve pits include leakage through overflow, personal injury, wildlife impact, and area exposure. The costs associated with pits include excavation, lining, increased location size, solid waste, and either burying or removal of solid waste.

Compared with reserve pits, closed loop mud system can avoid such risk factors and cost reduced. Closed-loop systems employ a suite of solids control equipment to minimize drilling fluid dilution and provide the economic handling of the drilling wastes. A typical closed-loop system includes linear motion shale shaker, mud cleaner and centrifuges followed by a dewatering system. The combination of equipment typically results in a “dry” location where a reserve pit is not required, used fluids are recycled, and solid wastes can be land farmed, hauled off or injected down hole.

There is a general misconception that a closed loop mud system is more expensive than a conventional pit program. Given the correct circumstances a closed loop system could be much less expensive. Factors that influence the cost are, depth of well, size of hole, length of drilling time, and of course the proximity to a disposal facility.

GN design oilfield solids control system and HDD mud recycling system as per your detailed requirement.
