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.
