Recently GN delivered a new designed solidification unit to our domestic client, it has been improved based on the previous design with the bigger storage capacity for solidification agent, flushing system, stronger mixing unit for heavy duty operation.

According to the feedback from the client’s rigsite, the storage capacity of chemicals is not big enough for drilling waste with more fluids, so the solidification agent storage box is bigger in the new design, so the new solidification unit could be used for multi drilling waste status- with more fluids content or with less.
Another change on the new solidification unit is the feeding hopper skid, the feeding hopper is much bigger than the previous stabilization unit, we consider the international container shipment cost, the auger could be disassembly during shipment and the whole solidification unit could be shipped by a 40 ft container.
Solidification unit is an economic way for drilling cuttings disposal when the fluids content is not too much, if the environmental laws is permit, but in some countries, solidification unit is not acceptable for environmental laws. Too much solidification agent cement and calc will be wasted and the cost will be higher compared with the performance.
Except for solidification unit, GN solids control also provided drilling waste management system, Thermal Desorption Unit, dewatering unit, vacuum unit, Screw conveyor, decanter centrifuge, vertical cuttings dryer, high G dryer shaker, Mono pump, etc. Solidification unit and dewatering unit, decanter centrifuge and high G dryer is normally used for water based drilling cuttings, vertical cuttings dryer system is normally used for oil based drilling cuttings.
We will keep improving our solidification unit according to the feedback of our clients, user friendly and the performance is our target to make our client satisfied.  For more information of drilling cuttings disposal, pls contact with GN solids control.

Unfortunately most of the HDD machines in India did not have a mud recycling system to reuse the drilling fluids, it is a huge loss of the HDD contractors that who never realized the importance of mud recycling system for HDD machines. You may own HDD rig made in USA, or you have HDD machines coming from China, whatever type machine you have, the mud recycling/ cleaning/mixing system can help you in the points below:

1) Reuse the drilling fluids or use the recycled mud to prepare for new mud, reduce the drilling cost
2) Lubricating the HDD rig
3) Cooling function
4) Reduce the drilling waste and only a small mud pit is required in the site, especially for some countries which have strict low for the drilling wells and drilling waste disposal, a mud recycling system can reduce the waste volume and make it easier to treat the waste properly.
5) Reduce the damage of the HDD machine and you can use it for longer time
At the beginning it is hard to convince the client who never used such mud recycling system for HDD projects to use it, he may ask why I should invest so much money for the mud recycling system. I can just leave it in the mud pit, it will be useless for me, etc. We have to show the client the successful case study of their competitors who began to use mud recycling system, they did job perfectly and fastly, the investment will be changed to profits in the future.

GN solids control provide mud recycling system for HDD machines Vermeer, drillto, America Auger, etc. We have different treating capacity design for options, 200gpm, 300gpm, 500gpm, 800gpm, 1000gpm, each mud recycling system with different storage capacity. The mud mixer could be included.

The sound control system mainly have the shale shake, desander, desilter, mud cleaner, decanter centrifuge etc .. Desander, desilter and mud cleaner are the crucial aspect for the system. The desander can separate the sturdy size from 40-60 microns, the desilter can independent the solid size through 20-40 micron and the mud cleaner can separate the actual solid size from 20-60 micron. The desander comes with 10 inch hydroclones, typically the desilter is equipped with 4 in . hydroclones and the mud cleaner is the combination of the desander, desilter and shale shaker. The hydroclones are made of polyurethane which is very light and also endurable. The mud cleaner can be equipped with 1 to three of 10 inch hydroclones, and can also be equipped with 6, 12, or 16 fecal material 4 inch hydroclones, based upon the oilfield actual performing condition. The bottom shale shaker can be 3 or 4 pieces of screen. The motors of the shale shakers are reliable and long lasting. There are two famous brand connected with motors that are being used right now, OLI from Italy and also Martin industries from US ALL. All the shakers vibration method is linear motion and that is mostly adopted by the majority of manufacturers in the industry. The completely removable hydroclones and manifold skid design make the connection involving desander, desilter and shale shaker very quick and easy.

GN 22inch decanter centrifuge for fast drilling

GNLW553-VFD centrifuge is 22inch jar size centrifuge. This is major bowl big volume centrifuge can be used for fast drilling. But not many clients choose this kind of model centrifuge.

Last week GN solids control shipped a 3 mud tank recycling system for CBM project in Shanxi, China. This is a 500gpm mud recycling system with 1 unit of shale shaker, 1 unit of mud cleaner and 1 unit of middle speed decanter centrifuge. CBM mud recycling system is different with HDD mud recycling system and oil drilling solids control system, the design should be compact design and with smaller storage capacity.

This system is customized design after communication with the client. But the separation cut point should be smaller compared with HDD mud recycling system, normally desilter cone separation point is 15 ~ 20 microns, which is enough and acceptable for Horizontal directional drilling. But after long period drilling, the ultra fine solids will accumulated in the drilling fluids, which is not suitable for preparing the new drilling mud and re-used for drilling, that is why a decanter centrifuge is adopted in the mud system, the separation cut point is 5 ~ 7 microns.
The configuration of the CBM drilling mud recycling system is as below:

(1)    3 panel shale shaker GNZS703E as the first phase cleaning equipment, to separate big solids from drilling fluids
(2)    GNZJ703E-1S8N mud cleaner with 500gpm treating capacity, 3 panel bottom shaker and 1 pc of desander cone and 8 pcs of desilter cone, the separation point of desander cone is 40 microns and separation point of desilter cone is 20 microns.
(3)    18 inch middle speed decanter centrifuge

Solids control equipments are commonly used in land rig drilling project for drilling fluids recycling and cleaning. Properly recycling the drilling fluids could significantly reduce the cost on drilling fluids and the discharged volume of waste cuttings. Offshore drilling also produces drilling cuttings and other waste material need to be treated. Among the material produced, the used drilling fluid is the first one need to be disposed.

There are many places where the solids control equipment would be used, one of that is the equipment used on offshore drilling platform. A very compact flat including all the drilling machinery standing firmly in the sea, when drilling, it will need the drilling fluids recycling system for treating the used drilling fluids. Due the limited space on offshore platform, the driller always adopt the double or triple layers shale shaker as the primary separation on used drilling fluids. The mud cleaning system on offshore platform includes all the necessary equipment comparing with land rig, just working on the sea.

Almost all the offshore rig platform has enough mud tanks for storage the drilling fluids. However, when there is over much ultra fine solids in the drilling fluids, the drilling fluids is not be able to be used anymore if without any further separation. At this time, this type used drilling fluids need to be transported to land for treatment. The barge ship is used to transport this type drilling fluids from offshore rig platform to the land and provide new and active drilling fluids for the rig. The barge ship need have many mud storage tanks so that it can bring sufficient mud to the offshore rig. The barge ship need also have the mud mixing equipment for mud mixing system on the ship. The mud agitator and mud gun would also be needed for mud mixing system.

More attention should be given to the explosion proof of the motor and control cabinet, as it will be more dangerous if there is a fire on offshore rig or barge ship than on land rig. Thus, the electric components used for offshore should be strictly marin explosion proof standard. The other thing need to be given more attention is sufficient wear parts storage for offshore rig, as we known, it will be much difficult for the drilling to get a small wear part once the equipment shut down. That will be a waste for both time and funds.

GN solids control brand decanter centrifuge has been used for high gravity solids drilling fluids successfully in Shengli Oilfield in domestic market. The features of the drilling waste fluids for this zero-discharge projects are as below:

High viscosity, high corrosive, high oil content, high pollution, difficult to be treated, high treating cost, etc.
The technical datas of the drilling waste management for the zero-discharge project is as below:
Drilling waste total volume: About 2000 tons each drilling period, each period is about 7~15 days
Solids content in the drilling waste fluids: experienced data 2%
Dry solids : 40 tons / period( approx)
The traditional waste water treatment equipment is hard to work continuously 24 hours automatically, the drilling waste cuttings is increased and discharged from shale shaker, desander, desilter , decanter centrifuge, especially for the shale shaker discharged cuttings, much of mud, cuttings are included in the drilling fluids, the cuttings size is between 5~ 20mm, If treated by the traditional belt filter for drying, the filter will be damaged and blocked.
After study and test in the client’s rig site, GN engineer team adopted our GNLW363CG-VFD decanter centrifuge for drilling waste treatment of this project. Our decanter centrifuge is 3 VFD control for main motor, back drive motor and pump motor, which can be used for different applications. And we can change the pulleys by changing the speed if required. Continue reading →
