GN Solids Control just launched a new type vacuum shale shaker to help oil gas drilling contractors reduce drilling waste volume and recycle more drilling fluids for a greener world. The vacuum shale shaker is a new technology to enhance the drilling fluids recovery by combining traditional shale shaker and vacuum screen. 
ViST is Vacuum Screen Technology, composed by a vacuum unit, catch pan(s) and hoses etc, which was first designed by GN Solids Control in June, 2017. It was proved to be a big success and highly efficient product when work together with a shale shaker to treat OBM, WBM and SBM.

Designed in a compact structure, this new type Vacuum Shale Shaker includes one negative pressure vacuum pump, one corresponding catch pan and hidden hoses to generate pulse or continuous pressure at the screen bottom during the operation of the shaker, so as to achieve the combined separation effect of vibration and negative pressure. 
Pulse frequency/time of the negative pressure can be controlled by an independent control box, and can also be switched to continuous negative pressure. 
The control box of the Vacuum Shaker, same with the traditional one, can control the shaker independently and work independently with the ViST. When it needs maintenance, the modular designed Vacuum Shaker can be used as a traditional one by removing the negative pressure pump, catch pan and hoses. On the contrary, the traditional shaker can be also upgraded to a vacuum shaker by adding those previous mentioned components. 
As one of the feedback from a drilling company GN ViST vacuum shale shaker reduced 35% drilling waste, which saves a lot of cost for the drilling waste disposal, and the recovered drilling fluids is also valuable. 
Installed under the last screen or mounted externally, the vacuum catch pan is connected with a ViST by hoses. The new type vacuum shaker is an electrical driven unit, while traditional ones demand a stable and continuous air source. Anti-splash SS cover is optional, double shale shakers and triple shale shakers can be customized. 
GN Solids Control also provides pneumatic driven vacuum unit, each one is able to connect with max. 3 sets catch pans. The compressed air from AC or the rig air supply is required to create suction on the last screen surface, pulling additional drilling fluids off the cuttings. Different with the electric vacuum shaker, the pneumatic vacuum shaker has a ViST fixed on one side and connected by much longer hoses. 
By adding a ViST on the shaker, a higher mesh screen can be used for the shaker to save the use of desander, desilter and corresponding drilling fluids feeding pump. Four grades of solid control process can be changed into two grades, and the mud treatment process will be simplified to reduce the well site area and personnel input, thus to achieve energy conservation and consumption reduction. Almost no additional space is required to meet the space requirements of both onshore and offshore drilling platforms.
In a result , GN Vacuum Shaker maximizes the volume of recovered and reused fluids and it provides dryer cuttings. Dryer cuttings mean less drilling waste and more recovery drilling fluids. So ViST can save money for operators on drilling fluids and waste management.
GN Solids Control specializes in designing and manufacturing turnkey solids and liquid separation equipment in oil & gas industry, environmental protection industry, construction industry and mining industry.

GN Solids Control manufactures different types of transfer pumps, among them GN Solids Vacuum Pump is a high efficiency transfer pump especially designed to move high solids content materials such as drilling waste.
This week GN Solids Control finished manufacturing of 2 sets vacuum pumps and will be delivered to Africa before China New Year holidays.

Vacuum pump is an air driven transfer unit, connected with air compressor or air source at the rig site. GN Solids Control shipped one wheel type 20B vacuum pump and one skid type 40B vacuum pump.
In fact, most of the oil & gas drilling waste is not easy to move as they usually have high solids content and viscosity. But GN made vacuum pump is able to suck and discharge any moveable materials as long as size less than 75 mm. Furthermore, it can pump the material to max. 1000 meters.
As for these 2 vacuum pumps, this African customer will use it to remove oil drilling cuttings in the rig site. When the vacuum pump is under operation with a proper air pressure, drilling cuttings are sucked into the pump shell first for some seconds with the inlet gate valve open, then the inlet gate valve will close and the outlet gate valve will open so the cuttings can be discharged.
 
GN Vacuum pump can work under automatic mode after set the two timers, and it can also work under manual mode to control the suck and discharge by operator.
Besides drilling waste or cuttings after treated by shaker, mud cleaner and centrifuge, GN vacuum pump can be also used for drilling mud transfer, waste pit cleaning, oil sludge removal from tank bottom, construction materials such as sands, silts, aggregates.
GN Solids Control also provides SS vacuum pump besides carbon steel for some special material usage. Welcome to connect with GN sales reps. for you customized cost-effective solution.

GN Solids Control shipped 3 sets double deck linear motion shale shakers and 1 set mud cleaners to one European drilling rig contractor last weekend. With these years’ upgrading, GN Solids Control now provides the F version shakers with the most satisfying working performance and convincing quality.
All these GNZS706 shakers that GN Solids Control manufactured are double deck shakers with totally 6 pcs (each deck 3 pcs) screens: tob deck working area is 2.0 m2 and bottom is 2.6 m2 which is 4.6 m2 working areas.

When a GN shaker is fixed with 2 decks’ screens, usually the top layer is the coarse deck which can remove big particles, and the bottom layer play as the second step to remove finer particles. However, when a shaker fixed with hyhrocyclones, the working process will be different, bottom layer separation first before feeding into cyclones and then the top layer screens separate again.
This European drilling contractor has some old NOV Brand VSM 300 shakers before, when they are considering to upgrade them they choose to use GNZS706 double deck shakers.

GN Solids Control made GNZS706 double deck shaker, easy and convenient to replace new screens by the fast wedge press units, save at least 30% total to replace screens compared to the tradition method.
With a large separating room, GN Solids Control shaker GNZS706 runs under linear motion with max. 7.2 G force, meet the demands of drilling mud solids control for large onshore drilling rig and offshore drilling rig during fast exploration.
GN Solids Control manufactures and sells over 300 sets shale shakers every year, besides these standard equipment, GN Solids Control also provides turnkey customized systems with multiple shakers or mud cleaners fix on the top of a mud tank, includes all in and out pipe lines, with centrifugal pump fixed on the tank bottom, and mud agitator or mud hopper on the mud tank for option usage.

GN Solids Control is a global solids and liquid separation equipment provider that has thousands of systems running successfully. This month GN Solids received another high comments on one hydrovac slurry dewatering system that provided 14 months ago.
GN hydrovac slurry system mainly includes the following treating components: feeding hopper, coarse shaker, fine shaker, desilter and decanter centrifuge.

GN Solids Control has provided dozens of hydrovac slurry dewatering system in US and Canada, as well as Australia and New Zealand. It helps hydrovac excavation contractors to save huge money on the slurry investment, and more importantly bring extra profit as those recycled pebbles, sands, silts can be resold.
