INTRODUCTION ‐ Coal is a source, seal and reservoir rock. Gas is sorbed on the coal surface. Typically over 90% methane with some ethane and d carbon b dioxide. d d
‐ Slow Sl i i i l desorption initial d i and d relative l i permeability bili effects ff create a “negative gas decline curve.” Unique production characteristics of CBM results in low but inclining initial gas production, peaking around 4‐6 years as the coal is d dewatered d (depressurized). (d i d)
MCFD or BPD D
‐ CBM production requires dewatering the coal formations. When the pressure is reduced, gases are desorbed and flow to the h wellbore llb via a naturall networkk off fractures f ( l (cleats). ) After gas arrives at the wellbore, it is produced utilizing conventional hydrocarbon gas extraction technology

( ) G = Gas content (sct/ton) a = ash content (%) m = moisture content (IM) fc = fixed carbón (%) vm = volatile matter (%) d = depth of coal seam (feet) ko = 0.8 (fc/vm)+5.6 no = 0.39 – 0.013 ko Rf = recoveryy ffactor (%) range Rf : 50% – 85%
Coal Cutoff • 300 – 1500 m (depth) • ≥1.5m (thickness)
Recovery Factor Estimating the RF From the sorption isotherm: (initial gas content – abandonment gas content) / (initial gas content) x 100 = % Recovery Factor
Depending on many factors, the expected range for Recovery factor might be 50% to 85%
Ryder Scott Conf CBM 2006
DRILLING ‐ CBM drilling basically similar to oil and gas conventional, except keeping the drilling cost as low as possible in order to achieve economics of the project since typical CBM development needs massive number of wells. In order to do so safe and creative approaches in CBM drilling is strongly recommended.
