Desander Desilter

GN Solids Control is the first manufacturer for waste management systems which are accepted by Russian market. Just a few days ago, GN has delivered a complete set of waste management system to Russia. Now, GN’s vertical cuttings dryer and its waste management systems are most popular among the end users. Although it is a tough year for all the oil relating industries, GN also sells lots of waste management systems to the clients and receives good feedback.

GNDC-40A is one of the 2 standard drilling cuttings waste management systems GN designed for different jobsite requests. GNDC-40A is more suitable for the waste management jobsites which are alongside with the drilling rigs, in this system, there is no tank for containing the liquid phase from the centrifuge, and the centrifuge is hosted at a certain height so that the liquid discharged from the centrifuge flows directly to the active tank of solids control system easily. And when matching with an effective set of solids control system, this drilling waste management system could work continuously.

GNDC-40B is another standard design of drilling waste management system designed by GN Solids Control. It is more suitable for the mud companies or somewhere specially for treating the drilling waste cuttings. In some countries, there is no need for a drilling jobsite to have a waste management system, and the drilling cuttings are transported and collected in a special place for further treating. In this case, we use GNDC-40B, which has a tank for the liquid discharged from vertical cuttings dryer and another tank for the liquid finally discharged from the centrifuge.

Besides above mentioned 2 kinds of standard drilling cuttings waste management systems, GN also has the individual modules for waste management equipments, vertical cuttings dryer, high-G drying shaker and high speed decanter centrifuge, each one could be regarded and used separately. In the coming CIPPE Shanghai, GN will show such modules, welcome to come and see.

Drilling waste cuttings management equipment is more and more used in the drilling industry nowadays. The main cutting drying equipments are the vertical cuttings dryer, drying shaker and high speed decanter centrifuges the cuttings transferring system. According to the different base of the drilling fluids and the cuttings transferring equipment, the drilling waste cuttings management system has several layouts onsite.

Almost the waste cuttings waiting for treatment are collected from the primary drilling solids control equipment like the shale shaker, de-sander, de-silter and barite recovery centrifuge. According to different transferring equipment, the different collection equipment would be used. If the user choose to use the auger as the cuttings delivery equipment, it is better to use the auger also as the waste cutting collecting equipment. The auger is located horizontally at the side of the solids control system mud tank; the length of the auger is decided by the mud tank length. The collected cutting was delivered to the drying equipment by another auger unit. If the user chooses to transfer the cuttings by using the slurry hose pump, then the cutting could be firstly collected by a hopper unit which is connected with a hose pump, the hose pump could transfer the cuttings to the drying unit through the hose. Using the auger would occupy much of the area of the drilling site, while the hose pump could be installed freely with less limitation of space.

As per different base of the drilling fluids, the vertical cuttings dryer or the high G drying shaker would be chosen. GN’s modular design vertical cuttings dryer is the main cuttings drying equipment for oil base cuttings, the effluence out from the dryer is stored firstly in a intermediary tank, then the effluence will be pumped to the waste decanter centrifuge for polishing. The water base cutting mostly transferred to the high G force drying shaker for treatment. GN’s modular design drying shaker unit has a beneath located catching tank for drilling fluids storage and pumped to the centrifuge for further treatment.

The decanter centrifuge could be installed on a telescopic skid, thus the active drilling fluids could flow back to the mud recycling system by gravity force. If the decanter centrifuge is installed on a low mud tank, then the effluence out from the centrifuge would first flow into the mud tank, and then pumped back to the mud recycling system.

 

At beginning of this month, GN has got an order for 2 sets of solids control systems for 1000 HP rigs which will be working in a middle east country, and the end user is a national owned drilling company in that country.

The 2 drilling rigs now are in USA, under fabrication, and the ordered solids control systems will arrive to the rig jobsite at same time when the rigs are ready. “It is a landmark and a great change of my company”, said the general manager of the drilling company, “because before knowing GN, all of our rigs and equipments were all from USA. GN Solids Control is the first China brand we use, and these solids control systems are only the beginning, but not the ending.”

North Africa market is very big oil drilling market, but very hard for oversea solids control equipment suppliers. The best way is to find partnership with local strong oil service company / mud service company to develop the market together.

 

GN Solids Control is China leading manufacturer for solids control equipment / waste management equipment. We already partner with the largest mud service / oil service company in North Africa for over 3 years. During the past years, we have cooperation on many different large projects.

1) Over 40 sets centrifuge project. All the centrifuge is working for over 20 sets drilling rigs solids control service.

2) Over 10 sets vertical cuttings dryer. All the dryer is working for WBM /OBM / SBM drilling waste management. The drying results can reach to 3% to 5%.

3) Over 10 sets high G drying shaker. The high G drying shaker can be used for treatment of water based mud drilling waste. Scomi in Iran also treat the oil based mud drilling waste by high G dryer shaker sometimes.

 

Except for above equipment for drilling waste management, GN Solids Control can also offer drilling mud solids control system / solidification unit / Thermal desorption unit. Etc. We may talk more about solidification unit here. This Solidification and stabilization are separate treatment techniques with similar goals. Solidification of wastes involves the production of a solid mass having sufficiently high structural integrity to allow transport and/or disposal of the solid without requiring secondary containment, i.e. mixing of sludge with shredded paper, sawdust, etc.

The working process including below:

 

1) The big waste collection hopper collects all the drill cuttings & drilling waste, which is conveyor to the mixing chamber by the underneath screw conveyor at pre-set capacity

2) Cement storage box is keeping cements powder, through the tubular screw conveyor, powders are sent to the mixer at pre-set capacity.

3) Absorber storage box is keeping reagent powder, through the tubular screw conveyor, powders are sent to the mixer at pre-set capacity.

4）There are 2ea 1.5inch liquid inlet, for water feeding, liquid chemical feeding, located beside the mixer inlet.

5）The high-shear mixer mixes all the material, and push to the front at the same time. When the solids go to the discharge port, it is already mixed sufficiently, then discharge

GN Solids Control is the first company to open market for solidification unit / stabilization unit. If you need more information, pls contact us freely.

 

The EXTRACTOR Dryer are be designed to remove NADF from drill cuttings from the drilling mud shale shaker.  The dryer is with capable or will be reducing the oil on cuttings to < 3% and to an overall total of < 6.9% when the drilling waste centrifuge is taken into account. Excess fluid will be recycled and packed after centrifugation and returned to the drilling mud active system for reuse. The system is not suitable for the treatment of water based mud cuttings.

The EXTRACTOR Dryer contains of a horizontally configured conical screen installed within a balanced cage that is driving at high speed by the  electric motor through a Cyclo- Gear drive gearbox. Positioned of the equipment within the cage is a scroll that turns and transports the separated solids from the machine to obtain highest cuttings dryness. The conical basket contains a suitable screen specially designed to minimize screen binding. The dryer machine is attached to an isolated sub-frame which in turn is mounted on a rugged oilfield skid for transport.

The EXTRACTOR Dryer will receives drill cuttings from the Solids Control equipment (shale shaker) by screw conveyor or vacuum system or and/or solids pump.  Drill cuttings then be transported into the Centre of the feed cone and distributed evenly through feed holes by centrifugal action into the flighting channels between the scroll and of the screen. As the drill cuttings pass through of conical screen, the solids layer becomes thinner and exposed to progressively more G-force.

The very high gravitational force will allows the liquid portion of the feed to pass through the cake bed and screen when the cake bed itself is continuously turned and swept outward to be discharged at the outer diameter of the screen. The dried drill cuttings exit from the front of the machine where they are either discharged to the environment or collected for further handling and/or treatment.

Three phase decanter centrifuge:

GN only provide 2-phase decanter centrifuge for oilfield applications as drilling, dewatering, waste management, etc. But we also have a requirement on the three phase decanter centrifuge, because some of our projects will need to separate solids, water and oil. If you are good supplier for three phase decanter centrifuge, pls contact with GN solids control. But GN vertical cuttings dryer is also an option for oil recovery in some cases. We provide a solution as below:

Firstly use a vertical cuttings dryer to recovery most of the oil from the waste cuttings, the oil content in the solids is lower than 5%. The recovered oil including some fine solids, GN decanter centrifuge can separate them out and then flow to the further treatment to get clean oil.

If you need oil sludge separation decanter centrifuge, pls contact with GN solids control or GN SOLIDS AMERICA in Houston.
