Solids Control system is an essential part of a drilling rig system, which is used for remove the drilling cuttings from the expensive drilling mud. In this way, the clean mud can be returned to the drilling procedure and to be reused. On the other hand, it is also protecting the environment by discharge less waste.
In a complete drilling solids control system, there should be shale shakers, mud cleaner, decanter centrifuge of middle speed, decanter centrifuge of high speed and the feeding pumps for the mud cleaner and centrifuges.
Just recently, GN Solids Control, the leading manufacturer in China in solids control industry, has provided a client from South America totally 3 sets of solids control equipment, including following:

1. shale shakers with model GNZS594J for 3 packages, totally 12 sets.
2. Mud cleaner, GNZJ594J-3S16N, each rig system need 1 set of mud cleaner to play the roles for desander and desilter cones.
3. Centrifugal pumps for desander and desilter cones, they are same as mission magnum centrifugal pumps.
4. Middle speed decanter centrifuge for each package, with model GNLW363D-GP.
5. High speed decanter centrifuge for each package, with model GNLW363D-VFD.
6. Screw pumps for each centrifuge as feeding pump.

Functions of each equipment: in fact, the solids control system are used for removing the drilling cuttings from the mud in a physical way, which means, each step of separation is based on the drilling cuttings’ particle sizes. The shale shakers are used to remove the most particles larger than 100 microns. Desander and desilter are working with centrifugal force generated by the cyclones’ structure, and their cuttings points are respectively 40 and 20 microns. The middle speed centrifuge are used for removal of particles from 5 to 7 microns, which here means barite recovery. And the high speed centrifuges are used for removing particles from 2 to 5 microns, extra fine ones.

If you need equipment like this or a turnkey solution even including tanks, please contact GN directly.

Drilling companies or drilling contractors are always rig owners who win projects all over the world drilling for oil exploration companies. Along with each rig, there is a solids control system, and a solids control system is comparably independent system among the 8 systems for a rig.

In a complete solids control system, there are following equipment involved:

Shale shakers, desanders, desilters, degasser, decanter centrifuges and pumps. In a recent project, a China drilling company has just purchased from GN Solids Control following equipment for a solids control system：

1. Desander GNZJ752J-1S. The desander cones are located after the shale shaker, which is used to remove particles above 40 microns. For this desander, there is a drying shaker with 2 pieces of shaker screens and a screen size of 1.35 square meter. Normally for weighted mud there should be a desander or desilter with underflow shaker. Here it is a one desander model with a 10 inch diameter desander cone.

2. Desilter GNZJ752J-8N. This desilte is located after the desander. It is called desilter cause it is used to remove particles larger than 20 microns which are mostly sized as silt. Same as the desander, it has an underflow shaker, too. Both the desander and desilter are fed by centrifugal pumps.

3. Vacuum degasser GNZCQ270B. Vacuum degassers are located after the shale shaker while before the cyclones. GN Vacuum degasser has no need of a large power. Instead, it can be regarded as a large agitator. GN Solids Control has 2 models of vacuum degasser available and the GNZCQ270 is the smaller one. Besides the vacuum degasser, GN Solids Control also has centrifugal degasser available.

In fact, GN is even more professional for design a complete turnkey solution involving all equipment like shake shakers, mud cleaners, middle speed decanter centrifuge and high speed decanter centrifuges. And all pumps needed in the solids control system are available.

The year 2022 now comes into the last month, and GN factory is still fully scheduled with new orders from all over the world. Recently, GN just finished the manufacturing for a batch of double deck shale shakers for oil and gas solids control for an European client.

GNZS706 double deck shale shaker has following features:

1. The shaker model is GNZS706, which means there are totally 6 pieces of shaker screens on the shaker. 3 pieces of screens are mounted on the upper deck, with a total screen area of 2.0 square meters and the lower deck also has 3 pieces of shaker screens with a total screen area of 2.6 square meters. Total screen area is 4.6 square meters.

2. Working principle of the double deck shaker: the upper deck of shaker is equipped with coarse screens as the 1st step separation and the lower deck we use comparably finer screens. In this way, the treating capacity is increased and the screen mesh is better protected for longer life.

3. GNZS706 double deck shaker has the quick pressing device for changing shaker screens easily and quickly. And such device is quite durable for performance. This function highly facilitates the operators when changing shaker screens.

4. GNLW706 double deck shaker uses 2 sets of vibrating motors which generate a linear motional high G force. It is suitable for both land rigs and offshore projects.

5. The shaker screens used on GNZS 706 Shale shakers are also made by GN Solids Control. GN Solids Control has a separate shaker screen factory with robot cutting and welding, producing high quality shaker screens.

Other famous solids control brands also have double deck shakers available, for example, VSM 300 from NOV Brandt is quite a popular model in Europe. Client for this order is buying GNZS706 for replace the existing VSM 300. GN Solids Control also has single deck shale shaker models, with 2 or 3 or 4 pieces of screens.
