On oil drilling rig site, Hi-G dryer shaker and double deck shaker is widely used for drilling cuttings treatment and recycling. They are both linear motion shale shaker. Some customer do not know the difference of Double deck shale shaker and High-G dryer shaker. As world top solids control and waste management equipment manufacturer, GN Solids can tell you the difference of the 2 types of shale shaker and choose the suitable model for your drilling rig.

Hi-G Dryer Shaker ( recommended model GNZS594, linear motion)

Compared with traditional shale shaker, this model with a Higher G force, can get better vibration screen separation. This model with 4 panel Mongoose shaker screen, can get bigger treating capacity. And the shaker screen is interchangeable with Swaco Mongoose screen, you can get the shaker screen from local Swaco distributor easily.

As it is single deck, relative easy to change shaker screen compared with double deck shale shaker.

Decanter Centrifuge has different functions when it works in different conditions.  As for oil and energy field, we usually use decanter centrifuge for mud system and drilling waste management. GN Solids has many years experience in manufacturering and sales. We have exported many decanter centrifuge to over 60 countries and areas. So far, GN Solids has established some branches to support the prosperous areas, like branches in USA, UAE, Australia, Russia.

The landfills are low-cost and low-technology, so until now, it is the most popular method for drilling waste disposalin developing companies, who do not have much concern about environment.

1 Landfill

After drilling waste are maximum recovered and the certain level for oil, salt, metals or industrial chemicals can reach the disposal standard set up by environment Department, it can be landfill disposal. Even with low-concentration levels, pits must be structurally sound and isolated from groundwater sources, so that it can not be thread of groundwater supplies.

Waste with slightly higher concentrations can be blended with clean soil to meet acceptable levels. Pits can be located within plant rooting zones, but cannot intersect with ground water tables. If waste exhibits toxic concentrations, disposal can only occur in specially engineered and legally permitted landfills (on-site or off-site)

2 Drilling waste management

Only when the drilling waste is maximum recycled and treatment and reach the certain level, it can be landfill. GN solids control worked together with drilling waste management service companies, we provide equipments to support the service company to do the drilling waste disposal service.GN Vertical cutting dryer can make the drill cutting dryer and oil content in the cuttings is lower than 5%, then the water can be chemical treatment and the cuttings can be landfill or others.

Although there are a lot of methods for drilling waste disposal, the core solution is to reduce the drilling waste and maximum recycling them. A proper solids control system can minimize the drill cuttings and recycle more useful drilling fluids, a good drilling waste management system can recycle more cleaning drilling fluids from the cuttings, both of them can less the drilling waste disposal. GN provide both solids control & waste management solution, you need further process for the drilling waste disposal.

The drilling fluids with the cuttings from the well are discharged to a rig shale shaker where the cuttings are separated from the drilling fluid. The separation step does not completely remove drilling fluid from the cuttings, some drilling fluid and additives remain on the drill cuttings.

Then such drilling cuttings with drilling fluids will be dropped into a GN drilling waste system, through physical way to separate the usable drilling fluids with unusable drilling cuttings. For example, hi-G shale shaker to separate larger drilling cuttings, then verti-cutting dryer to separate drilling cuttings with oil less than 5%.The usable drilling fluids are treated by decanter centrifuge, then clean drilling fluids and water will back to rig again.

The cuttings separated by verti-cutting dryer with less than 5% oil can not be drain off directly, it may pollute the environment. We must use chemical way to continue the treatment.

Drilling cuttings treatment method:

Thermal desorption, re-injection, incineration and solidification.These methods have been applied in the site, they may have their own advantages and disadvantages.

Thermal desorption:

use of the patented Porcupine Processor to remove all water and oil, leaving a residual total petroleum hydrocarbon on cuttings of less than 1%.

Re-injection :

Decanter centrifuge can be used as 2 functions: one is to used in drilling mud solids control system, to recycle drilling fluids and get barite. The other one is to used in drilling waste management system, to treat the drilling waste and recycle drilling fluids. GN decanter centrifuges are working in many sites in Brazil for such purpose.

Other related equipments with centrifuge:

In drilling fluids solids control system, centrifuge is used after desander and desilter, when they need to separate fine solids.

In drilling waste management system, centrifuge is used after cutting dryer, when they need to recycle the clean drilling fluids and drain off the cuttings. Sometimes it is used after hi-G shaker, it depends on the drilling mud type.

GN can provide both equipments related to the centrifuge.

People rent centrifuge because of the high cost of US centrifuge, also because of the maintenance cost, sometimes clients only want to use the centrifuge for a short while, so centrifuge rental is economic for them. But most of the clients rent centrifuge because they have Continue reading »

GN new products hi-G dryer GNZS85-3 is designed to replace the old model hi-G dryer GNZS63-4. GN Hi-G dryer shaker is with long shaker deck big capacity which is used for waste management to treat the drilling cuttings from the primary solids control equipments, like shale shaker, desander, desilter to dry the solids for transportation, and make the fluids easier for future treatment. To know more info of primary solids control equipments, pls check GN website.

What is the features of GNZS853 compared with GNZS63-4?

1 Even it is 3 –panel hi-G dryer, its screen area is larger than 4-panel hi-G dryer. The larger the screen area is, the dryer the cutting is. Total deck screen length is 2550mm, the total deck screen length of GNZS63-4 is 2520mm. Total screen area of GNZS85-3 is 3.2m2, but the total screen area of GNZS63-4 is only 3.15m2. And GNZS85-3’s screen area and total deck length is larger than Derrick 4-panle shale shaker/mud cleaner.

So 4-panel shaker is not must be better than 3-panel shaker.

2 3-panel shaker screen can enlarge the effective screen area, the waste screen area is less compared with 4 screen panel. It can improve the performance of hi-G dryer.

3 Mechanical deck adjustable while operation for reliable performance.
