GN solids control ,a specialised mud system manufacture for oil&gas drilling,HDD&CBM drilling,water well drilling .till now our water well drilling mud system have been working in Mongolia,Libya Susan and some South Asia market.

An Overview on Drilling Operations in Sudan

Water Wells Drilling background:

Seasonal shallow wells in alluvial sediments deposited along the seasonal streams courses locally known as Jamam/ Meshish providing very limited water.

Hand dug wells lined with bricks and stones are oldest well known water technique.

The first deep borehole in Sudan was drilled in 1919 at Um Ruwaba using a steam driver percussion rig.

Rotary drilling rigs were introduced in early fifth of last century. Down the hole hammer rigs (DHH) were introduced by Unicef in 1978 for drilling of slim boreholes .

Water well mud system

Drilling systems in Sudan:

A. Down The Hole drilling using air drilling system.

B. Rotary drilling system using liquids – mainly bentonite. 

C. Percussion drilling system.

D. Manual digging using experiences of local skilled people.



GN supplied a lot of mud system for water well drilling, and the first one is exported to Mongolia, while the customer checked our system performance and indicate their sub-company in Mongolia to purchase from GN. Then we exported Water well drilling mud recycling system to Mongolia, and Water well drilling mud cleaning and mixing unit to Mongolia, Then exported Two Unit 200GPM Mud Recycling System Delivery to Australia

 Installation instruction

1 Best installed near the pumps and pumping source, and to shorten the length of the inhalation segment, reducing the loss of the pump self-priming pump must be installed below the level of the pumping source.

2 Firstly pour the concrete foundation, place″T″type channel iron when pouring, and install skid base after the concrete freezing. All the bases are required to be level in order to avoid the machine shaking.



3 Coupling installation

3.1 Coupling must be concentric with Shaft, the two axes must be aligned and its error limits: The value of parallel deviation cannot be over 0.25; the value of intersection angle error of the two axes cannot be over 0.12.

3.2 Check: Checking the two errors by percentage meter with pedestal (As fig. shown). Its two touches must keep close to the outside circle surface or face of the coupling and rotate slowly when checking. Take the max reading shown on the meter as error value.

The hopper design along with the venturi mixer ensures that clogging and build up of chemicals is avoided. Upstream of the mixing eductor a stream is diverted to a radial premixer above the mixer inlet. Powder chemicals are pre-wetted in the radial pre-mixer before entering the venture stream in the eductor, thus eliminating “fish-eyes” and microgels.

A mud-flow device, also called a jet hopper, in which materials are put into the circulating mud system. The mud hopper is powered by a centrifugal pump that flows the mud at high velocity through a venturi nozzle (jet) below the conical-shaped hopper. Dry materials are added through the mud hopper to provide dispersion, rapid hydration and uniform mixing. Liquids are sometimes fed into the mud by a hose placed in the hopper.

GNSL series Jet Mud mixer is special equipment to prepare and increase the drilling fluids weight by adding and mixing  bentonite, change the fluid density, change the mud density, viscosity, and dehydration. The effect is more prominent matching with Shear Pump. GNSL jet mud mixer is a unit used together with the solids control system for petroleum drilling and horizontal directional drilling(HDD). The unit includes one sand pump, one jet mixing hopper and one jet mixer that are installed in a base with pipe valves. It is safe and stable and can be moved conveniently. At the same time,we can make Twin-Jet Mud Mixer according to the user requirements.It is designed by GN solids control bentonite mud mixer,drilling mud tank jet mixer.

GN can assist with properly sizing a hopper to fit your system.  There is no reason to be forced to mount the hopper on top of the mud tanks since the jet-venturi allows for convenient location of the hopper.  Sizing assistance should be requested when extensive piping or elevation is planned for the downstream side of the hopper.

Nowadays, the most popularly used oilfield shale shaker are BEM(Balanced Elliptical Motion) and Linear Motion. In China, GN Solids Control is the first one who got the API Certificate for producing shale shaker and other drilling fluids recycling equipments for oilfield application.

 Linear Motion Shale Shaker

Linear Motion Shale Shaker

When need shale shaker BEM or Linear Motion

Usually, shale shaker is used as the first stage drilling fluids recycling equipments in the Mud System, and the drilling fluids with cuttings flow into the shaker distribution box through rig elevated manifold.

  • Linear Motion – for fast conveyance and heavy loading

Linear motion shaker is especially effective while drilling top hole sectiong where heavy, high volume solids are usually encountered. In these intervals, shakers need to generate high G forces to effectively move dense solids across the screens.

  • BEM – for maximum retention time and drier cuttings

The BEM type shale shaker has gentler reduced G force, and the special vibration mode make the solids stay on the screen for longer time. This results in drier solids, improved drilling-fuid recovery, longer screen life and reduced operation costs.

BEM Shale Shaker Manufacturer

MI Swaco, a Schlumberger company, could offer the Mongoose PT daul motion shale shaker which could be adjust the vibration mode from linear motion to BEM “on the fly” by fliping the switch without suspending or shutting down the operation.
GN Solids Control, only foucs on International market and high level domestic market, could offer both the Linear motion and BEM shale shaker used in not only Oilfield, but also the HDD & CBM.  The simple structure design and top quality make GN get more and more praise from our customer.
Mongoose daul motion shale shaker by using an extra 0.6hp vibration motor to allow the shaker perform on an unparalleled level, GN’s BEM shaker is using 2 units motor with different power.

Comparing with BEM shaker, Linear motion is more acceptable due to the mature technical and large quantity oilfield application experiencies. GN Solids Control would be your reliable supplier for solids control equipments once you have any request aroused.

Person who works on drilling site know that there are several additives in the drilling mud, like bentonite,clay and Polymer. When add the polymer into the drilling mud, we may use the shearing pump.


In a drilling mud recycling system, for the bentonite and other additives, we could use the centrifugal pump to shear and mixing them. But for long strings polymer, only the shearing pump could be used for its wider flow pass and smooth vanes.

Always the shearing pump is package together with hopper, mud gun and transfer line which could transfer the mixed mud into each tank compartment. The impeller of GN shearing pump is made of high wear resistant cast iron for longer service life. Any need for shearing pump and other solids control equipments, just feel contact with GN Solids Control.
