CBM (Coal Bed Methane) exploitation will need the drilling process before the combustible gas being taken out from under the ground. Same as most of the drilling project, the CBM drilling will also request a drilling mud recycling system for cleaning the drilling mud what will ensure better drilling performance and save a lot on mud consumption.
Not like the drilling mud system used in oil gas drilling, CBM mud system normally has a compact structure with small storage capacity that depends on the mud tank dimension. However, the functions of full-stage solids control or mud recycling process should be equipped in the system. Just like the mentioned solids control system that sent to Shanxi Province in China, where is main place for coal reserves, and also has many coal mining plants. Where there is coal reserve, there will be the CBM.

It is a very standard configuration of solids control system in this article, specifications as below:
1. GN very popular 3-panel screens design shale shakerGNZS703E-HB for coarse solids separation in the drilling fluids. Back type mud logging box effectively reduce the flow and the impact force onto the screen so that the shaker screen could be protected. Horizontally welded steel beam on both sides of the shaker deck and a wide screen area ensure the shaker unit could run under a G force of 7.5 with flow rate at 500 GPM.
2. The mud cleaner unit is equipped with same model drying under shaker for easy maintenance in future. 1 de- sanding and 8 de-silting cyclone is the very standard configuration what GN suggested for a treating capacity of 500GPM. To consider the transportation convenience, GN mud cleaner has a removable hydrocyclone frame in case somewhere has the transpiration height limitation. This mud cleaner will request 2 units sand pump for mud transferring, while the pump are also provided and installed on the tank.
3. This system was also equipped with GN 18 inch decanter centrifugeGNLW452C for fine solid particles separation. GN 18 inch decanter centrifuge has both fixed speed and VFD model. Few days before, Baker Hughes just got several units GN 18 inch VFD model centrifuge with Max speed up to 2800 rpm.
4. 3 mud tanks for all mud recycling, intermediate, and mud mixing process. Normally, GN will provide mud mixing unit with mixing hopper and pump unit installed on tank skid or a independent skid.

For CBM drilling, GN solids control system was ever equipped to American brand Schramm rig for another Shanxi project in China. Click below link to read full story.
