Recently, we have 4 sets of 500gpm HDD mud system ready for delivery. Two sets of them is for domestic biggest pipeline HDD drilling contractor CPP and another two sets is for Middle East HDD drilling contractor, which have business in Egypt, South Africa, UAE, Saudi Arabia, Oman etc. All of them are GN old customer who have used GN mud system for long time. Like CPP, every year, they buy at least 2 sets from GN Solids Control, which is becoming the most important GN HDD customer. We cherish their feedback and each time make some improvements. Together with CPP, GN Solids Control is becoming the leader manufacturer for compact mud recycling system and mud cleaning system.

Africa is a good region for import & export business. North Africa and west Africa is full with oil & gas resources, countries like Nigeria, Libya, Egypt and Algeria. There are many mud service companies and solids control service companies and drilling companies there, which can have lots of business with GN Solids Control. South Africa and Middle Africa is full with golds/ diamond resources, countries like South Africa, Tanzania, Ghana etc. There are many diamond drilling rigs service companies and HDD contractors.

GN Solids Control is a China leading company who focus on solids control equipment. All the separate equipment can combine into oil drilling mud system or compact and economy mud recycling system which is professional for small rigs.

Oil drilling centrifuge is used for solids control service, to separate the fine solids from drilling mud. Stable working pressure pump with smooth liquid flow can add better performance on the centrifuge. GN Solids Control is China No.1 centrifuge manufacturer with professional experience on centrifuge operation and feed pump choice.

For solids control and drilling cuttings treatment equipment supplier, 2015, focus on GN Solids Control.

 1) Fixed speed screw pump

GN Solids Control choose top screw pump supplier Netzsch Germany brand pump. After many years cooperation, Netzsch & GN have built long terms cooperation relation with reliable quality, reliable delivery time and competing price. The positive displacement pump is single screw pump, can feed centrifuge without shearing the mud or without agitating the mud, slow inner flow speed, remains stable capacity, steady pressure, no Vertex will be generated with this screw pump.

If the end user wants one variable speed match with centrifuge, we can offer separate VFD control panel to control the motor frequency on the pump.

 2) Mechanical speed adjusted screw pump

If people don’t want the separate VFD control panel, we can also offer mechanical speed adjusted screw pump. However, the cost is much higher than general pump and also the delivery time is much longer. As many customer are pretty familiar with this kinds of pump, the end user prefer to this pump.

The feeding function is almost same with pump with separate VFD control panel.

Up to now, GN Solids Control have mature solids control equipment models. This can meet most of the requirement from end users, but not all. Some special requirement from customers, we have to take more time to do some necessary works. Eg. Shale shaker. GN Solids Control have 3 basic model shale shaker, GNZS752 series shaker, GNZS703 series shaker and GNZS594 series shaker. The treating capacity is 200gpm, 500gpm and 600gpm separately.  For workover rig or small geothermal rig, the separate shale shaker is enough to treat the returned drilling mud from rig, but for large oil drilling rig, 2 or 3 sets of shale shaker generally required.

Dual Connection Shale Shaker

GN just got Purchase order from Egypt Drilling Company. They require one set Dual connection shale shaker. The dual connection shale shaker should come with distributor to separate the drilling mud evenly from the well. GN Solids Control connect two sets GNZS703 series shale shaker with same big base to connect. You can see more details from the pictures.

GN 1000gpm Dual connection shale shaker technical specs:

Shaker model: GNZS703E-HB

Shaker qty:  2 sets

Total treating capacity: 1000gpm

For details of GN shale shaker, pls check on GN website: http://www.gnsolidscontrol.com/shale-shaker/

There are many pumps need to be used for solid control system, like centrifugal pump, submersible slurry pump, shear pump, screw pump etc. The pump is accessory equipment to solid control system, not main equipment, but also necessary for your smooth job. If the pump quality is not reliable, you may find many troubles during the work.

GN Solids Control Co., Ltd. is the first API and ISO certified solid control equipment manufacturer from China. Their equipment is widely used in many areas of the world. The reliable product quality and nice service win good reputation for them. Hereunder, we see one importance pump, shear pump in all perspective.

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

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.

Whatever the drilling is, if only there is mud system, you will have mud mixing and agitation issues after a period of drilling.

Mud mixing equipment

GN jet mud mixer is specially used for mud mixing. GN Jet mud mixer is composed of a venturi type hopper and a centrifugal pump, we have 4 models available, GNSL150-45S,GNSL150-35S, GNSL100-25S,GNSL100-25M with 1320gallons/min, 880gpm, 400gpm and 264gpm mixing capacity.

Mud mixing and agitation equipments

Mud mixing and agitation equipments

How a venturi hopper work?

The fluid velocity must increase through the constriction to satisfy the equation of continuity, while its pressure must decrease due to conservation of energy: the gain in kinetic energy is balanced by a drop in pressure or a pressure gradient force. An equation for the drop in pressure due to the Venturi effect may be derived from a combination of Bernoulli’s principle and the equation of continuity.
Mud agitation equipments

Mud agitator is mainly used for mud agitation, sometimes for mud mixing. Also in some applications, vacuum degasser also be called a” big mud agitation equipment”.Mud agitator is composed of electric motor and gear box, the popular connection method is direct connection, in some countries, they still use shaft connection mud agitator.

What is the difference in operation between positive displacement pump and centrifugal pump?

Positive Displacement Pumpswill not p roduce the same flow at a given speed (RPM) no matter the discharge pressure.

positive displacement pump

positive displacement pump

Positive Displacement Pump must not be operated against a closed valve on the discharge side of the pump because it has no shut-off head like Centrifugal Pumps. A Positive Displacement Pump operating against a closed discharge valve, will continue to produce flow until the pressure in the discharge line are increased until the line bursts or the pump is severely damaged – or both.

The positive displacement pump can be applied as

  • rotary lobe pump
  • progressing cavity pump
  • rotary gear pump
  • piston pump
  • diaphragm pump
  • screw pump

When positive displacement pumps serve as a screw pump for feeding drilling fluids decanter centrifuge, when you change the frequency of the main motor through the VFD control panel, the treating capacity of decanter centrifuge will change, so the flow rate need to be lessed.
