Hebei GN Soids Manage Company., Ltd. set up it's department organization as well as stockroom within Houston Tx this past year. Since that time we're maintaining stocking the primary equipment presently there.

mud agitator with regard to solids manage tend to be products which get rid of exercise cuttings in the drilling liquid whilst moving as well as drilling. The actual mud agitator all of us filled within Houston is actually GN Solids Control's brand new design GNZS594E-HB. mud agitator are utilized in order to procedure unweighted as well as weighted, water-based as well as oil-based drilling liquids. Mechanised power is actually employed to boost the gravitational pressure exerted upon solids which are contained in the actual dirt program. oilfield mud agitator can utilize more than 3, 000 G-forces about the liquid/solids blend, that sets apart the actual weightier solids in the lighter in weight solids. Furthermore, higher G-forces individual good solids through fluid. The actual mud agitator all of us filled within Houston is actually GNLW 363 sequence as well as GNL W553 sequence. When using mud agitator, it is best and other solids control equipment to run together.

The Hi-G dryer not only ensured environmental compliance with DTI regurgitation but exceeded the operator’s own in-house target of 80 GMS/kg. A total of 534 bbls of oil based mud wast recovered and Oil On Cuttings (OOC) figures were significantly reduced. It must be noted that the OOC target set by the operator was net even thought the majority of screens utilized on the shaker were 180-230 mesh. This can be directly attributed to GN screen technology which allows greater screening capacities from the same size shaker without increasing OOC level. Over the first there wells, fluid losses overboard equated to 0.085 bbls/ft.

Hi G dryer shaker


It mud be noted that until the advent of GN Hi G technology, the traditional method for control of OOC was install a cuttings wash/cleaning system. This was not only an expensive solution. But in some cases a very inefficient one, which sometimes reported higher figures than that being discarded from the shaker. As it is, the Hi G dryer requires minimal supervision. Together with its low operation costs and significant savings in fluid, it is an attractive alternative to any cuttings cleaning system. It can also be utilized well with high cost “pseudo” mud and/or “closed loop” systems.

GN Hi-G dryer shaker for Drilling Cuttings Drying System


Another major benefit of the Hi G dryer technology, sometimes overlooked, is the elimination of whole mud losses from the shaker. This historically has ensured that the shakers were never run at their optimum capacity and thus the solids control system efficiency was adversely affected. Incorporating the Hi G dryer down steam allows the shakers to be run close to maximum capacity without the concern of whole mud losses.

In the oil well drilling industry, mud density is a measure of the weight of the drilling fluids in a given volume and is normally measured in pounds per gallon (lbm/gal) or (ppg). It is frequently referred to as mud weight. In the operation field it is measured using a mud scale or mud balance. The instrument consists of a constant volume cup with a lever arm and rider calibrated to read directly the density of the fluid in lbs/gal (water = 8.33 lbs/gal) and pressure gradient in psi/1000 ft (water = 433 psi/1000 ft) or pounds per cubic foot (water =62.4 lbs/ft).

(Mud Balance)


The mud weight is related to the specific gravity of the drilling fluids. Specific gravity is the ratio of a materials density to the density of water. Pure water has a specific gravity of material twice as dense as water would have a specific gravity of material half as dense as water would have a specific gravity of 0.5. Low gravity solids have an average specific gravity of 2.6. The solids are 2.6 times the weight of the same volume of water.


(Decanter Centrifuge)


In traditional drilling fluids, barite is used to increase the mud density in order to condition the proper drilling fluid that is required by the drilling formation. Other chemical additives such as halite (salt) or calcium carbonate can also be used for increase the mud weight. Mud weight can be decreased by dilution or solids control equipment such as a decanter centrifuge. A proper designed decanter centrifuge can recover barite as much from the return drilling mud.

Cuttings drying is normally referred to as secondary drying of drilled cuttings. In the solids control equipment system, the drilling cuttings off the primary shale shakers can be passed over a second dryer shaker to recover useful drilling fluid. The recovery of oil-based drilling fluids coupled with a 10-25% reduction in disposal volume is usually easily justified and has become standard procedure in areas where so-called pitless drilling or closed loop systems are the norm. Generally, the secondary dryer shaker is a four-panel with large screening area machine running at above 7 G force at the screen surface. Drilled cuttings from a dryer shaker typically test between 8 and 12% base oil (NAF) by wet weight.

vertical cuttings dryer

Accordingly, there has been increased interest in lowering the ROC figure by the use of different types of drying equipment. Cuttings removed in the primary solids control section enter in the feed inlet of the dryer. Processed cuttings are removed after the dryer removes oil (or NAF). The oil or NAF is recovered and returned to the drilling fluid system. The quest for improved technology to reduce the ROC figures is ongoing with a number of competing machines and technologies. The main equipment includes decanter centrifuge and vertical cuttings dryer.

What is 3 VFD PLC Controled decanter Centrifuge?

3 VFD means the decanter centrifuge have 3 VFD driving system, one for the centrifuge main motor, one for the back drive motor, the third is for the decanter centrifuge feeding pump motors. The PLC electric Controlled system means the centrifuge set up, operation, are thru Programmable logic controller system.GN PLC and VFD decanter centrifuge display the info. on the touch screen.


GN 3 VFD PLC Controled decanter centrifuge Features

The GN VFD and PLC controled centrifuge allows operator to adjust bowl speed and differential speed and pump speed without changing the pulley and belt. The fixed speed centrifuge can use mechanical method to change pulley for speed changing, but it may not reach the perfect differential speed for different applications. And the pulley changing for the speed is limited in several speed, and VFD decanter centrifuge can give any speed for the customers and any differential speed

Oilfield PLC Centrifuge

Anyway, depends on differential applications, and budget, customer may also choose to use the simple machine fixed speed decanter centrifuge with some pulley to change speed. And use the bypass function on GN decanter centrifuge feed tube to get the correct capacity from the feeding pump.

For GNLW363BG fixed centrifuge if we fix proper pulley to get the gearbox input speed from back drive motor to be 1152 RPM or connect the gearbox directly with coupling to a 6 Pole motor,and run centrifuge at 60HZ.

  • Case 1: Centrifuge Bowl Speed 3200 RPM, the Differential speed =( 3200-1152)/57=36RPM
  • Case 2:Centrifuge Bowl Speed 2500 RPM, the Differential speed =( 2500-1152)/57=24RPM
  • Case 3: Centrifuge Bowl Speed 2000RPM, the differential speed=(2000-1152)/57=15RPM


The Fixed Speed Centrifuge by changing pulley to get different bowl speed, but the back drive motor speed is the same, so it is not convenient to change the differential speed.For each fixed bowl speed, only one differential speed.

Decanter centrifuges are specifically built for oilfield applications, both onshore and offshore drilling activities. Adjustable operating parameters enable the decanters to be employed for a wide range of solids control purposes in drilling fluid systems including: Barite recovery from the active mud system or from surplus mud in storage, separation of drilled solids from unweighted muds.

The decanter is equipped with a hydraulic Coupling and belt pulley for main drive and a belt pulley system for the back drive, discharge funnels for solids and liquid discharge as well as a gearbox overload switch, cover open switch and vibration switch.



In most cases Decanter centrifuges do a good job of separation without benefit of chemical additives. However, some fluids containing a high proportion of colloidal fines, e.g. in drilling waste applications, may need to be flocculated to make them separable. Flocculent chemicals are expensive, so it pays to exploit the other tuning capabilities of the Decanter to the full in order to minimize the dosage.
GN solids has varies of choices on decanter centrifuge from top notch material build to economic material build, from big bowl big volume to small bowl small volume, from fixed speed to variable speed.
