shale shaker screen

World top manufacturer for solids control and drilling waste management equipment, they get an urgent request to deliver one high G shale shaker with one sump tank to be used as drying shakers for OBM (Oil based mud) cuttings.

Below is the detailed request of customer:

1- Quotation for drying Shaker and related skid itself.

2-  Quotation for 15 bbls sump tank with 1 x 4”  Flange and 1 x 2” Flange connection; the customer also attached pictures of a drying Shaker with sump tank.

The customer give answers very soon as below:

1) We intend to install a shaker on a tank that length and width of the sump tank is exactly same as drying shaker length and width basket and we want the height of the sump tank to be at range of 1 m.

2) We need two flanges by 2″ and 3″ size to be installed on width side close to the bottom the tank to be able to connect a Welden pump (air supply type) and suck collected oil for the sump tank that has been installed below the H-G Drying shaker into the active mud system.

And customer further request: for drying shaker, they usually don’t need the back buffer box.

Based on above information, GN Solids control engineer give proposal as below:

1) High G drying shaker model GNZS594HGE-LD, with hoper feeding on shaker top for drilling waste management system.

2) Sump tank with length and width is exactly the same as drying shaker length and width basket, and total height with skid is 800mm for usable capacity 15bbls

3) Further more, GN Solids recommend its screw conveyor to transfer cuttings from solids control shaker to the high G drying shaker. Customer is satisfied and give orders.

Double deck shale shaker and High G shale shaker is widely used for oil and gas drilling rigs site.They can be used for both mud solids control or drilling cuttings waste management.

They are both linear motion shale shaker. Many customer do not know the difference of Double deck shale shaker and High G shale shaker. Below is the explanation from world top solids control and waste management equipment manufacturer – GN Solids Control. Let GN tell you the difference of the 2 types of shale shaker and choose the suitable model for your drilling rig.

Double deck shale shaker, linear motion: GNZS703D

double deck shale shaker linear motion

GNZS703D is the typical double deck shale shaker. It utilized 2 each shaker screen for top deck and 3 each shaker screens for bottom deck.

Advantages of GNZS703D double deck shale shaker

1). For the same API size and the same area bottom shaker screen. double deck shale shaker can treat a bigger capacity. The wide-meshed shaker screen on top deck can separate most big size solids before the mud enter into the bottom deck. It greatly reduce the load of bottom shaker screen.

2). For the same API size and the same screen area shaker screen. double deck shale shaker can separate the drilling mud or drilling cuttings more dryer. As there are 2 times shale shaker separation.

Disadvantage of double deck shale shaker

The double deck shale shaker have advantages of bigger advantage and dryer separation result, but it has some difficult to change shaker screen. And the cost of replacement shaker screen also higher, as there are 5 each screen for a shale shaker.

High G shale shaker, linear motion: GNZS594

linear motion high G shale shaker

linear motion high G shale shaker

GNZS594 is a high G shale shaker model, with linear motion. It uses 4 panel shaker screen. And the shaker screen interchangeable with Swaco Mongoose shale shaker, composite material. It is single deck, relative easy to change shaker screen compared with double deck shale shaker.

Conclusion

So the user can choose shaker type per your drilling rig conditions and per your applications (for solids control or for waste management). If you have a higher solids content, or want bigger capacity, and take more time for screen changing is not problem, you can choose double deck shale shaker. If you prefer fast screen changing, high G shale shaker single deck is better.

Functions of solids control equipment- shale shaker

Solids Control shale shaker is the first stage separation equipment for oilfield drilling mud cleaning system. It utilizes vibrating motor to generate vibrating strength. The vibrating strength drive the drilling mud going through the shale shaker. When the drilling mud go through the shaker screen, clean mud will filter into mud tank. Not allowable bigger solids will pass the screen surface and been discharged.

Types of solids control equipment – shale shaker

Per different motion design. There are mainly 2 types of shale shaker:

1) Linear motion shale shaker. It is the most common shaker model for oil and gas drilling solids control system

2) Balanced Elliptical motion shale shaker. It is not recommended for oil and gas drilling, as the flow capacity is big. The BEM shaker, while mud flow not equal, the motion of the shaker will be changed. And performance not good. Mostly, professional users prefer linear motion for a wide use.

Separation size of solids control equipment – shale shaker

The separation size of the shale shaker equipment depends on shaker screen size. We call it API size or mesh size. The API defers from API 20 to API 325 per API RP13 standard.

Through changing different API size shaker screen, the solids control shale shaker can separate solids size min. above 40 microns (at API 325 shaker screen)

If you do not need to separate so fine solids, you can choose more fine shaker screen, Like 800 microns @ API 20.

The common screen API size for solids control shale shaker is API60, API80, API100, API140,API160. Customer can choose the suitable size per drilling mud condition.

AWD Angle Adjustment System for GN solids control shale shaker

GN AWD Angle Adjustment System for solids control shale shaker is the patent design. It is synchronized change for both sides. You can adjust from any side, the angle change is the same for both side.

GN have a options for AWD Angle Adjustment: Left side of the shaker is a small motor for automatic control. And there are control for the small motor on shale shaker control panel. Right side of the shaker utilize tools for angle adjustment.  GN will offer tools together with the shaker. Customer can choose any way to change the angle.

Shale shaker can also combined with desander or desilter assembly and used as mud cleaner. For more information of GN solids control shale shaker, you can visit GN website or contact GN group.

There are rubber ring for sealing on most shaker screen model, like Derrick503 screen, Derrick48-30 shaker screen, Brandt Cobra shaker screen, GN Solids shaker screen, and many other shaker screen models.

Functions of the sealing rubber:

1) Sealing between screens and shaker deck. To avoid un-treated dirty mud seep into mud system, and damage the mud system machine.

shaker screen sealing rubber

2) To reduce the bad effect of vibrating to the shaker screen. Protect screen from strong vibrating.

What will happen if the sealing rubber not workable

1) The screen frame will touch directly with shaker deck, and damaged within a very short time

2) The worst result is, if the screen rubber damaged, the dirty mud from well head will flow into mud system directly with much solids. It requires a higher capacity on downstream equipment processing, or even make damage to the downstream machine, like desander, desilter or vacuum degasser

If the material of the sealing rubber not strong enough and not very good at anti-corrosive, the high temperature drilling mud with heavy sand will damage the rubber very soon. The shaker screen will be broken very soon. Dirty mud flow into the mud system from the shale shaker deck with heavy sand and solids. It will have bad effect to the mud system.

GN Solids Control utilzie high quality material for sealing rubber. They can offer high quality shaker screen with reasonable price.

Huge surprise is coming for shaker users.
