Recently one set of containerized vertical cuttings dryer system and containerized drilling fluids treatment decanter centrifuge unit are ready for shipment to overseas mud company for OBM drilling cuttings treatment. The system configuration is as below:

1. vertical cuttings dryer module including: GNCD930G vertical cuttings dryer, container to install the equipments inside it, screw conveyor which is used to collect drilling cuttings and transfer to vertical cuttings dryer, screw conveyor to collect the discharged cuttings from vertical cuttings dryer discharge port and transfer it to waste collection box, flushing pump for vertical cuttings dryer, lifting device for vertical cuttings dryer screen basket replacement, transfer tank, etc. All of the equipments are installed in the container with windows and doors. The purpose is for fast installation and convenient transportation, also it can meet the requirement for cold weather area use in Winter.

2. Decanter centrifuge module including: GNLW363D-VFD vertical cuttings dryer, container with window and doors, decanter centrifuge feeding pump, screw conveyor to collect the discharged solids from centrifuge discharge port and transfer to waste collection box. If without the container with special Insulation layer, the project in the area with low temperature in Winter will have to stop and wait till the fluids be unfreezed, the customized design can meet their requirement in special conditions.

Except for containerized vertical cuttings dryer and decanter centrifuge system, GN solids control can also provide skid mounted drilling waste management system for oil based mud drilling waste treatment. The features of skid mounted drilling waste management system is convenient operation, convenient transportation, high efficiency, economic cost. It can be lay on the drilling rig besides solids control system, or it can be installed in the drilling waste treatment facility, the screw conveyor system can be installed flexibly according to the layout and space limit.

The shaker screens replacement is very convenient, by ratchet wrench for quick shaker screen disassemble and assemble. The side fluids outlet and bottom fluids outlet is optional , it can be used in different sites.

The ViST vacuum screen can be applied for OBM, SOBM, WBM, the recovery efficiency is up to 30% ~50%, it can be used for mud temperature -15 º to +85 º. It is air operated, no need electricity required.
For more information of ViST vacuum screen, pls consult with GN Solids Control.

GN solids control will participate in CIPPE 2023 with our new technology and equipments, the exhibition information is as below:

Exhibition Name：China International Petroleum & Petrochemical Technology and Equipment Exhibition (cippe) 2023
Exhibition time: May 31-June 2, 2023
Exhibition location: New China International Exhibition Center, Beijing (No.88, Yuxiang Road, Tianzhu, Shunyi District, Beijing)
GN stand No.: E2168 (Hall E2)

What equipments will be showed in CIPPE?
1. vacuum shale shaker
2. Decanter centrifuge, as one of the core equipments we produced, GN decanter centrifuge has been widely used for different applications, such as oil & gas drilling fluids cleaning, barite recovery, drilling waste treatment, industrial waste water dewatering, core drilling waste water recovery, oil sludge treatment, Hydrovac Slurry Dewatering System, dredging slurry separation, mining tailings separation, etc. Based on your different requirement, we will use different model decanter centrifuge with different treating capacity, G force, speed, driving system. We can produce decanter centrifuge from 9 inch bowl diameter ,14 inch, 18 inch, 22 inch to max 30 inch bowl diameter, and the bowl length and angle will be different as per different project.

3. Vertical cuttings dryer for OBM drilling waste treatment
4. Solids vacuum pump
5. Screw conveyor, we have fixed speed and variable frequency drive system for option, the rotation direction can be single and two way as per requirement, and the feed port and discharge port can be also customized. We can provide auger diameter 10 inch, 12 inch, 14 inch,16 inch, 18 inch for your selection, each section standard length is 12ft, the screw length can be 1 section 12ft, 2 section 24 ft, 3 section 36ft, 4 section 48ft.
6. shaker screen

…and more.

As everyone known, a good solids control system can benefit a lot in different aspects, such as increase the drilling rate, make the drill bit longer working life, lower drilling mud cost and disposal cost for barite, chemicals, water, cuttings; reduce horsepower losses to gel and viscosity; reduce the possibility of lost circulation and blowouts; less drag pulling pipe; reduce surge and swab pressures; less differential pressure sticking; better cleaning work, etc.

A complete solids control system consists of primary shale shake, desander, desilter ( or mud cleaner), degasser, decanter centrifuge, etc.
Shale shaker is the first phase solids removal. To use a proper mesh shaker screens to reach your required result according to the cut points. The high performance shale shaker has reduced the solids from the drilling fluids, the fluids drop into the sand trap, and pumped by centrifugal pump and feed to desander cone, desilter cone. If the shale shaker separation performance is not good, the desander cone and desilter cone will be damaged very fast.

Hydrocyclones- desander & desilter & mud cleaner, are the second phase cleaning and third phase cleaning equipments. 10” cone and 12” cone is normal used as desander hydrocyclones; 4” cone is normally used as desilter hydrocyclones. A 500gpm desander use 1ea 10” cone, 1000gpm desander use 2ea 10” cone, 1500gpm desander use 3ea 10” cone. A 500gpm desilter use 8ea 4” cone, 1000gpm desilter use 12ea 4” cone, 1500gpm desilter use 16ea 4” cone. We will choose different numbers of hydrocyclones for your different treating capacity requirement.
As one of the experienced solids control equipments manufacturer in China, GN solids control produce complete line solids control equipments and mud system, we also provide design and first time commissioning service to our clients. Pls contact with GN solids control for more information.

Recently a unit of mute solids vacuum pump are ready for shipment, it will be used for tunneling slurry transfer. The vacuum pump is used to suck the slurry used for Tunneling project and discharge to another place, the max suction distance is 50m horizontally, max discharge distance is up to 1000m horizontally. The vertical lifting depth is up to different materials. The max solids content allowed is 80%, and max solids size can be pumped is up to 75mm, it can be used to transfer tunneling slurry, especially for long distance transfer. Since the vacuum pump is 100% air operated pump, no need electricity supply, it is suitable for hazardous area application. When the vacuum pump is installed near city center, a mute tank is applied to reduce the noise.

Tunneling slurry is a mixture of topsoil, Portland cement, and water. The consistency of the slurry is different depending on its purpose in a repair project. The slurry is made thinner and more watery for filling purposes and thicker with less water for lifting purposes. In foundation repair and tunneling, slurry is used as a filling material and is of a thinner consistency.

We have 3 models of solids vacuum pump for option with different flow rate, GNSP-10B with flow rate max 10m3/h, GNSP-20B with max flow rate 20m3/h, GNSP-40B with max flow rate 40m3/h. There are automatic mode working and manual mode working for option based on different working conditions. After several times testing for suction time and discharge time, the user can adjust the timers of suction and discharge until it reach your requirement.
It can be widely used to transfer waste mud, drilling cuttings, oil sludge, tunneling slurry, animal waste, hazardous waste, sand and solids, etc. material. If you need solids vacuum pump, pls contact GN solids control.
