Coalbed Methane

Improve economic recovery

Coalbed methane (CBM) is a natural gas extracted from coal beds.  Economically-producing CBM wells can be complex due to extremely low permeability, significant water production, and extensive natural fractures.  In addition, the reservoir properties are sensitive to stress profiles, effectively changing permeability of fractured reservoirs during drilling and completion operations. 

BJ Services offers comprehensive analysis of the reservoir profile to effectively select the proper cement and fluid treatment.  In addition, we provide lightweight cements that are durable can withstand the pressure and thermal cycles to achieve long-term zonal isolation.  Our fracturing fluids are specially formulated to withstand the high-temperatures and stress needed to effectively stimulate CBM wells, improving overall fracture conductivity and increasing production.
