The process of drilling and completing coalbed methane (CBM) wells is similar to wells in conventional reservoirs. Coring, however, can pose special challenges.
The first step in creating a drilling program for a CBM well involves gathering information about existing wells in a given area. CBM wells range in depth from a few hundred meters to more than 3000 m. As a result, several rig types and sizes may be suitable for a given well plan. The most common rig type is the conventional rotary drilling rig, although modified water-well rigs commonly are used to drill shallow coal wells in locations such as the Powder River basin of Wyoming.
CBM drilling is same like oil&gas drilling and will produce large of solid phase in drilling fluid, so in order to protect the environment and decrease the drilling cost must have remove drilling cuttings. Solid control system is suitable for CBM drilling which can effective clean the drilling fluid.
