Africa, is a mysterious land to many people’s eyes. But the Oil and Gas linked GN Solids Control to the African countries via the good quality solids control and waste management equipments and responsible service of GN commissioning team. These 10 sets of GN Decanter centrifuges are ordered by a large African drilling company, they are ready for dispatch now and will be shipped to Africa in recent days.

GNLW363 is most popular product of GN. 14 inch bowl diameter decanter centrifuge is most popular size internationally, because: 1. the treating capacity depends mostly on the bowl diameter, and such treating capacity could meet most applications. 2. In order to get a good drying result, the length-diameter ratio is better at 3, and the cost for a 51 inch bowl length is of more cost-effective during production.

GN’s advantages in this model: for the same bowl diameter and specification of centrifuge GNLW363, GN Solids Control provide 4 options: 1, Economic solution: GNLW363CD, fixed speed, 2. Economic solution: GNLW363CD-VFD, vfd control panel. 3. Highest solution: GNLW363CG, fixed speed, 4. Highest solution: GNLW363CG-VFD. Customers could choose any of them per the jobsite need or per budget.

GNLW363CG series decanter centrifuge: it is not only the highest GN standard centrifuge, but also, it is highest international standard centrifuge in solids control field. See what material GN chooses for this centrifuge: SS2205 for rotating bowl, SKF bearings, easily adjustable liquid level ports, most anti-wearing tiles on impeller and etc.

Customers could choose per their jobsite condition fixed speed one or VFD control panel. In case of VFD control panel, the working speed could be easily set from 0 RPM to 3200 RPM. In case of fixed speed, it doesn’t mean only 1 speed only. Customers could choose 2 extra pulley and belt for another 2 operating speeds, in order to be suitable for different applications.

Recently, we got tender invitation from Shell in Middle East. We also have cooperation with Shell China. They have some special requirement on solids control equipment.

Drilling fluids Shale Shaker

Two shale shakers capable of handling 10.5 ppg mud weight at 1000 gpm.The electric motors for shale shakers DO NOT HAVE TO BE ZONE CLASSIFIED AS OPERATION IS NOT IN A LIVE HYDROCARBON ENVIRONMENT. Common header tank for all shale shakers. Mud return flow lines shall enter from the rear at the base of each shale shaker header tank, mud gas sensor to be installed in the header box and readings screen within the drillers control cabin and Cement bypass to be installed. Supply screens for the shale shakers as per the clients recommendations, screen sizes will be supplied at later date.

GN Solids Control Shale shaker, GNZS594E-HB can meet the requirement for this tender file.

For earth surface engineering,  the contractor no need to consider about combustible gas or explosive gas, like HDD no-dig engineering, piling engineering, tunneling engineering, waterway dredging engineering. But for deep drilling engineering, like oil & gas drilling, Coal bed methane drilling, shale gas drilling, all the motor and control panel should be ex-proof standard. The standard should also separately as per different geological conditions. Some security equipment is also necessary.

1) Mud Gas Separator ( poor boy degasser) — security equipment in solids control system for deep drilling

When gas cuttings happened to drilling fluid, the gravity and viscosity of drilling mud will be changed a lot and cannot satisfy the requirement for drilling, even lead to kick or blowout accident. The mud gas separator , made of high quality material , can be used to separate the harmful gas effectively.

GN Solids Control can supply the best quality mud gas separator with other solids control equipment, like shale shaker, decanter centrifuge, mud cleaner etc.

GN Solids Control is not only professional solids control equipment supplier, but also supply different mud tanks for different functions. The size of mud tanks range from big mud tanks for oil drilling solids control system and mud plant to mini mud tanks, eg trip tank, sump tank, pill tank etc.

1) Pill tank and trip tank for solids control mud system

Pill tank is used for conditioning the drilling mud by add barite, bentonite or other heavy weight additive.  The size is about 1000x1000x1500mm. The position is placed after decanter centrifuge, fixed on the mixing mud tank. After adding heavy weight additive, the drilling mud can be mixing fully by force from Jet mud mixer with a centrifugal pump.

Trip tank is used for feeding the well when change the drilling tubes. It is generally positioned besides the shaker tank.

Recently, GN Solids Control just offer one sets of 1500HP rig mud system to RG Petroleum.  Pill tank and trip tank is included.

Oil Based Mud ( OBM) is much costly in oil & gas drilling. In order to recycle and reuse the OBM discharged from solids control line ( shale shaker & desander & desilter), lower down the drilling cost and make it easy to further treatment in environmental friendly way, OBM Recycling Unit is becoming much popular for drilling contractors.  Many drilling contractor will buy one set OBM Recycling Unit for their own use or rent service from third party service company. With customer’s feedback and suggestions, GN Solids Control develop one set OBM Recycling Unit. With  the OBM Recycling Unit, your work will be simplified, effective.

GN Solids is a professional oifield drilling mud vacuum degasser manufacturer and supplier in China oil drilling mud solids control industry. As the pioneer in this industry, GN Solids is capable of providing customers with series products ,such as oil & gas drilling fluid solids control equipment, drilling decanter centrifuge, drilling waste management equipment and drilling security equipment.

Application of drilling mud vacuum degasser

To recomve invading gas from drilling mud, it is necessary to install a vacuum degasser. So that the invading gases may not impact mud properties. This invading gases can lead to risks and affect the lifespan of solids control equipment.

Vacuum degasser is a special-purpose oil drilling mud solids control equipment and a new type one for the drilling fluids system. Drilling mud vacuum degasser can get rid of various gases invading drilling quickly. Drilling mud vacuum degasser is very important for keeping mud gravity, stabilizing mud viscosity and reducing drilling cost. At the same time, drilling mud vacuum degasser can be used as a heavy-power mud agitator and supported applicable to all types of drilling mud purification system. The drilling mud vacuum degasser design of the structure is scientific and rational. So we are able to achieve an effective gas-liquid separation, filter out impurities and to ensure that the exhaust pipe is always smooth.
