GN Solids Control made an oil-based drilling cuttings treatment system for a CNPC company. GN Solids Control made and designed and system per client’s job site situation. So it can suit for the clients’ situation well. Clients are happy with the performance of the OBM treatment system. Both the team leader and job site workers are satisfied with the system, and they said that, after applying GN waste management system. They can recovery more usable drilling mud. Their drilling waste and their drilling cost are both reduced. And they can save cost and manpower on the waste material shipment.

The oil based mud treatment system made for CNPC is a complete package. It is a skid mounted cuttings drying system with processing equipment, mud and cuttings transfer equipment, and electric control system.

Below is the major equipment included in the skid mounted oil based mud cuttings drying system:

Firstly, there is a vertical cutting dryer. The vertical cuttings dryer is mounted on a separate skid. VG dryer is also called VG centrifuge, it is the major equipment to treat the oil based mud and cuttings discharged from shale shaker. GN high quality vertical centrifuge can reduce the oil on cuttings to as low as 3% ~ 5%. In many countries and regions, less than 3~5% OOC can be discharged directly. Even not, it is already very dry like powders. It is easy for movement and for next process treatment.

Secondly, there is a 14 inch decanter centrifuge in the oil base mud cuttings drying system. The decanter centrifuge is used after the vertical centrifuge to reduce the mud weight. Enable the recovered mud qualified for drilling activity.

3 sets screw conveyors are equipped in the system. One screw conveyor is located under the shale shaker to collect drilling cuttings discharged from shale shakers. Another screw conveyor is located inclined to transfer the cuttings from shale shaker and feed to the vertical cuttings dryer. The 3rd screw conveyor is inclined and under the vertical cuttings dryer. It is used to transfer the drying cuttings from VG dryer to the cuttings containers.

GN Solids Control is the 1st one manufacturer in China who ever sent the drilling cuttings solidification unit to client’s jobsite. It was predictable that many comments regarding the performance of GN solidification unit would come back. More important is how to response to these comments.
GN is always keeping developing new products, which is the reason of the first unit drilling cutting solidification unit coming from GN. Some of the comments on GN solidification unit are positive, while some are very good suggestions for GN to perfect the design. The unit sent to site was designed whole assembly installed on one skid, which makes the unit too long to move and locate the unit easily. The new design divides the machine into 2 parts; one is for solidification agent storage, the other part is for mixing. These 2 parts could be located more freely according to the site space. Comparing with old model, the new one has larger tank for agent storage, on top of the tank, hand rails are installed. The agent bag pallet could be put on top of the tank, which greatly increases the working efficiency. Though 2 parts, the whole system still could be put into one 40ft container for oversea transportation.

Cuttings Solidification Unit

The drilling cutting discharged out of the shale shaker and decanter centrifuge could be fed into the solidification unit for treatment. However, there is a misunderstanding on the performance of the solidification unit: No matter how wet the cutting is, so long it is fed into the solidification unit; the dry material will come out. This is not correct. The much wet the cutting is, the more solidification agent will be used. Hence, the operator should make the cutting as dry as possible before feeding into the solidification unit.
GN’s solidification unit was proved greatly saved the man power on site as it can working continuously, the speed could also be adjusted as per the working condition. Solidification unit is one of the final solutions for water base drilling cuttings. Easy operation and maintenance are its advantages.

Pitless means no need to dig a pit on the ground to collect the drilling cuttings. Nowadays, though the solids control system is widely used in oil drilling, some drillers still dig a mud pit on the ground to collect the drilling waste cuttings discharged out from the primary solids control equipment.
So long as the drilling rig is working, the solids control system has to be working all the time as the used drilling fluids is continuously coming out from the drilling well. With the issue of much strict environment protection regulation, the driller need find a solution to reduce the volume of the discharged drilling cuttings; in the meanwhile, much more drilling fluids could be recovered to reduce the drilling cost. And then they got a
conclusion, if I can establish a pitless drilling cutting disposal system, all the problems would be solved.

pitless drilling cuttings disposal system

Pitless Drilling Cuttings Disposal System GN

Pitless drilling cuttings disposal system requires a good connection between the traditional solids control system and waste cuttings management system. The most important is there should be a final solution on how to make the discharges environmental friendly. For the waste cuttings out of the shale shaker and cyclone unit, no matter water base or oil base. We have the high G force drying shaker and vertical cutting dryer unit to make the cutting much dryer so that more drilling fluids could be recovered. The recovered drilling fluids would be pumped
to a high speed centrifuge for separation of fine solids in the drilling fluids. After treated by the centrifuge, the drilling fluids would flow back into the storage tank for drilling reuse. The screw conveyor is used to transfer the drilling cuttings from shaker unit to the cuttings dryer machine. Therefore, it is no need to dig a mud pit, or at least, a large and deep mud pit on the ground to collect the drilling cuttings. We nearly realize
the pitless before the final disposal of the dry cuttings.
There are Thermal Desorption Unit and solidification unit could be used to dispose the cuttings from the high G force drying shaker and Verti G dryer. These 2 systems could make the cuttings none hazardous for environment. Finally, the pitless drilling cuttings disposal system is established.

For the mining, GN have made a few customised layout systems, the first one is for Poultry, the customer co-design the system along with GN; then for the coring ming project, we style and design a very small system to get diamond drilling; then some decanter centrifuge with different layout for mining or prospecting water; now another customized system for Philippine mining or prospecting project.
This system contains a shale shaker, two centrifuges. The problems delivered to us is: deep subway, have mining water, having mixtures, different particles, which will destroys the pump which usually keep pumping the lakes and rivers out to keep it able to perform there. The pump is created in German, good quality, but expensive, we want to keep it within good condition, and not easy to get repalcement parts. To sum up, we need another technique to make the pump running properly.
Then we tried a variety of choices, to keep it below ground, or keep it along with the land. To only start using a centrifuge, or use several centrifuges. And questions continually come like do we need shaker, do we need desnader and many others.

Hydraulic Jackup Mud Recycling System

With the professional help from clients’ engineer, we finally what is design, and also modify this current operation flow of the mining or prospecting water. Then finally detox the singing water, and then transport to the surface. Considering that the purpose is not for consuming, so do not try.

Furthermore in the mud recycling system, it contains 2 Nemo pump, which is manufactured by German Netsch.

Specifications connected with decanter centrifuge
we have VFD cp to achieve stepless bowl rate adjustment to enhance mud treatment method performance
we use De dos niveles stainless steel SS2205 for centrifuge casting to improve bowl sense of balance, centrifuge balance, as well as progress performance on corrosion weight.
We use Tungsten carbide tiles protecting the twist conveyor impellers to enhance the particular performance when treating large mud.
When the system appear the site, GN solids control engineers should go to the site for the first time having and also operator training. To be sure all goes well and the right way.

The drilling operator might know that after several times reuse of the drilling mud, there will accumulate more and more ultra fine solids in the mud that cannot be separated out with physical method even by using high speed decanter centrifuge unit.
The accumulated solids will rise up the mud specific gravity that will greatly affect the mud performance. While, in order to keep the normal density of the mud, under this circumstance, the flocculation no doubt is the most popular method to be used.

polymer mixing unit

The flocculation process is produced in a type of machine called polymer mixing unit. This unit is used to mix the polymer that will be fed into the centrifuge to gather the fine solids in the mud. This polymer mixing unit is always connected with the centrifuge unit in the solids control system. After the separation by primary solids control equipment like shale shaker and cyclone unit, most of the solids larger than 5 microns could be removed out. The centrifuge unit plays an important role in this flocculation process. Sometimes, this centrifuge is called dewatering centrifuge.
GN’s polymer mixing unit is designed as 3 compartments mixing tank with automatic dosing conveyor and agitating device. Dry chemicals and water are fed into the first compartment for mixing, and then overflow into the second compartment for maturing process. The third compartment is used to store the solutions waiting for use.

dewatering centrifuge

The material of this machine body is PP. At each compartment, there is installed one automatic agitator with stainless steel made agitating shaft and impeller. The chemicals feed hopper is also made of SS304.

In order to realize the continuously mixing, the tank compartments are installed with liquid level control device. The mixing, maturing and storing process continuously transfer with low labor cost. The PLC design makes the operator adjust the solution concentration as per request, high automatic degree, and no need human watch over.
GN could provide the polymer mixing unit with dewatering centrifuge containerized for weather proof. For more information, welcome click to see GN Dewatering System.
