Solids control for Coal Bed Methane (CBM) Drilling

Coal bed methane(CBM) is a form of natural gas that is extracted from coal bed seams. Smetimes it is called coalbed methane, or coalbed gas, or coal mine methane (CMM). The primary energy source of CBM is a substance called methane (CH4), which is colourless, tasteless, non-toxic & flammable, making coalbed methane available to be used in all natural gas appliances in our home and also commercial applications such as electricity generation. In recent decades it has become an important source of energy in United States, Canada, etc. In Australiahas where has rich deposits, it is known as coal seam gas (CSG).

OGEM Solid Control System for CBM Drilling
CBM is generated either from a biological process as a result of microbial action or from a thermal process as a result of increasing heat with depth of the coal. It is hold loosely in the coal bed seams by the water & underground pressure. As the main content of CBM, methane has very low solubility to water.  To explore CBM, the underground water must need to be removed by pumping, which would reduce the pressure on gas and allow it to detach from the coal bed seam. Thus, CBM that hold in the coal bed seams can be released to the surface with the flowing of water, then CBM are separated from water and collected by special device at the surface.
Coalbed methane is usually very shallow, mainly around 1000 meters. That is why the drilling rigs for CBM are normally for 1000 to 2000 meters. The type & density of drilling fluids for CBM development must be designed and fixed according to the formation pressure, and also need to allocate appropriate solids control equipment, such as shale shaker, mud cleaner, centrifuge, etc. For surface well & intermediate section drilling, drilling medium should refer to the conventional CBM drilling medium optimization principle, while for horizontal well drilling, it should use superior drilling medium, non-clay drilling fluids, fresh water, gas, such as nitrogen, air, etc. & also froams to avoid drilling medium to harm the coal bed seams.
