With the oil price at a high level, more and more energy companies are trying to expend the production so as to more the more drilling contractors or drilling mud service companies are making capital investment on large oil and gas drilling mud solids control equipment and drill cuttings waste management systems.
Recently GN Solids Control finished another batch of oilfield centrifuges and drilling cuttings screw conveyors for a Middle Eastern customers. It mainly includes 9 sets drilling waste decanter centrifuge, 3 sets oil based mud cuttings dryer, 12 sets screw conveyors and 12 sets screw pumps.

1.GN Decanter Centrifuge
GN decanter centrifuge is one of the more popular drilling mud treating equipment especially the 14 inch bowl size among those various models from 9 inch to max. 30 inch bowl.
GN decanter centrifuge runs at high rotating speed, the rotating bowl and screw propeller rotating at the same direction but with a differential speed so the large density solids are pushed along the internal bowl and discharged from the solids port, while the relatively clean water is collected in the middle circle and pushed through the liquid ports.
2.GN Cuttings Dryer
GN Cuttings Dryer is one key treating equipment when speaks of oil base cuttings or synthesized base cuttings treatment. Usually after treated by GN cuttings dryer oil on the final cuttings can be downsized to less than 5% from 15%, recovered oil can be send to refinery plant for further treating and resell.

Screen basket of the Cuttings Dryer is hard faced, with 3 different openings 0.25, 0.35 and 0.5 mm for option. GN cuttings dryer is self-lubricated with an automatic oil lubrication system.
3.GN Screw Conveyor
Screw conveyor is widely used to transfer solids materials with limited distance. These 12 sets GN screw conveyors are used to collect the cuttings after treated by shale shaker, desander or desilter and feed into GN cuttings dryer.

4.GN Screw Pump
GN screw pump is also called GN positive displacement pump, which usually used as the feeding pump for decanter centrifuge. Due to the special structure, every run of the rotator is a fixed volume, so it can feed a linear capacity fluids by control the rotating speed which can be controlled on GN centrifuge’s HMI control panel.

GN Solids Control is now a leading drilling mud solids control equipment manufacturer in the world, as one of the largest market for GN, Africa takes a very large market share especially when the oil price is at a high level this year.
Just last week, GN Solids Control delivered some drilling mud solids control centrifuges to a African drilling rig contractor.

Centrifuge is the key treating equipment in the drilling mud solids control, usually drilling mud from the drilling rig is send to the shale shakers which distributed by feeding box after removed harmful air by poor boy degasser, and then drilling mud further remove the fine particles by de-sander or de-stiler before finally send to decanter centrifuge.
GN Solids Control decanter centrifuge is able to remove solids larger than 2-5 microns, the rotating bowl and screw propeller run at different speed to achieve drilling mud solids control no matter it is light gravity drilling mud or heavy gravity one. GN decanter centrifuge can also run at low speed to recover barite from drilling mud.

If classified by the rotating bowl size, GN Solids Control decanter centrifuge has nine inch, 14 inch, 18 inch, 22 inch and 30 inch models for different options. All decanter centrifuges’ rotating bowl are made by centrifugal casting, and solids discharge port protected by tungsten inserts and the screw propeller protected by tungsten carbide tiles.
As for this batch of drilling mud decanter centrifuge, GN Solids Control provides 6 sets of 14 inch bowl decanter centrifuges, all controlled by GN VFD box fixed with HMI touch screen where running parameters like the rotating speed, differential speed etc can be changed conveniently. Centrifuges are fixed with temperature sensors and vibration sensors to monitor the two main bearing running in good condition without over heat and also protect the whole rotating assembly without abnormal vibration.

GN Solids Control as a world leading mud cleaning system designer and manufacturer has been providing thousands units to HDD contractors. Last month, GN Solids Control shipped one set 240 m3/h HDD mud cleaning system and one set 120 m3/h HDD mud cleaning system.
All GN Solids Control made systems are effectively to be used for solids and liquid separation, and the typical treating equipment includes shaker, cyclone, centrifuge and centrifugal pump etc. In short, GN uses gravity differences of liquid and solids to achieve the goal of get clear water and dry solids.

1.GN 1000 GPM HDD Mud Cleaning System
It mainly includes 2 sets of shale shaker GNZS703F, 1 set of mud cleaner GNZJ703F-2S12N, 22inch rotating bowl centrifuge GNLW554EP-VFD, 4 sets mud tanks and one jet mud mixing unit (composed by jet mud hopper and centrifugal pump).

2.GN 500 GPM HDD Mud Cleaning System
The 500 GPM hdd mud recyler contains similar treating unit such as 2 sets shale shaker GNZS703F, 1 set mud cleaner GNZJ703F-1S8N, 1 set 18 inch bowl decanter centrifuge GNLW452, 2 sets mud tanks and 1 set jut mud mixer.
GN Solids made HDD mud recyclers help drilling contractors save huge cost on the drilling mud as after used clean drilling mud can be reused and more importantly less waste discharge to the nature.

All shaker screens used on GN shale shakers and GN mud cleaners are made by GN Solids Control. GN Solids Control is the only China screen manufacturer who can provide a API RP 13C 3rd party report which can guarantee GN made screens are strictly on the cut point and conductance.

Nowadays, it is a trend that more and more HDD drilling contractors start to use decanter centrifuge to remove finer particles from the drilling mud, as before only shaker or desilter is used which can only remove solids larger than 25 microns. More decanter centrifuges will be used in the HDD industry in the future.

GN Solids Control has been manufacturing shakers for many years, includes 2 panels, 3 panels, 5 panels and 6 panels if classified screen quantity. GN Solids Control also builds dual motion shale shaker, as most of the shaker GN Solids Control provides to customers are linear motion ones, some drilling contractors prefer to use dual motions which is linear vibration and elliptical motion.
Different motions shakers has different specific usage or advantages. Generally speaking the linear motion shaker is mainly used for mud with low viscosity, large discharge, large solids percentage, big and sturdy particles. While the elliptical motion shaker is suitable for completely different drilling mud. So based on these advantages or disadvantages, GN Solids Control made linear motion shakers are mainly used in the first and second stage drilling, and the dual motion shakers are widely used in the third and forth stage drilling.

As for these 2 sets dual motion shale shakers, they are provided to an offshore drilling company. GN Solids Control is able to provide DNV lifting certified equipment for offshore drilling platform, besides shakers, GN Solids Control has also provided mud cleaners, decanter centrifuges and cuttings dryers with DNV lifting frames to various customers.
All the shaker screens are GN shakers are also made by GN Solids Control. GN Solids is the only Chinese screen manufacturer who are verified by API RP 13C 3rd party.
