Coal Bed Methan ( CBM ) drilling required mud recycling system need to be compact design for fast moving. The CBM mud recycling system get a same working procedure with oil and gas solids control system but details change on equipment model choose and tank layout. A whole CBM mud recycling system including poor boy degasser, shale shaker, desander, desilter, decanter centrifuge, mud agitator, centrifugal pump, mixing hopper, mud tank, etc.

CBM Drilling Features

• Hole wall stability not good. Coal rake strength is low, accident easy happen
• Coal rake easy get polluted, there are hardness for coal rake protection.
• Coal rake broken a lot, gas around, hard to get a core.
• CBM gas collection time long, need CBM production hole long working life.

CBM Mud Recycling System Features

• CBM mud recycling system need compact design, tank connection is soft pipe or hard steel pipe by hammer union. The tank size better 40ft container size with container locking at each corner of tank. Tank bottom can make a 5 degree floor for solids easy discharge at clean gate.
• One set shale shaker or 2 sets shakers depending on mud flow requirement. The buffer box for shaker better sit on shaker to save shaker length, so that a whole shaker sit on tank width for easy delivery.
• 1 tank or 2 tanks depending on tank storage capacity, mud agitator installed on clean tank storage compartment to avoid solids settling down.

AIPU CBM Mud Recycling System

AIPU built different size of CBM mud recycling system with different mud flow and tank storage capacity. 500GPM, 800GPM and 1000GPM CBM mud recycling system are the most popular model for CBM drilling. Other than CBM mud system, AIPU supply mud system for HDD (horizontal directional drilling), diamond drilling, oil & gas drilling, TBM ( micro tunneling ). The working procedure for different industry normally same but different industry may need different special design for details.
