INTRODUCTIONINTRODUCTION

‐ Coal is a source, seal and reservoir rock. Gas is sorbed on thecoal surface. Typically over 90% methane with some ethaned b d dand carbon dioxide.

‐ CBM production requires dewatering the coal formations.When the pressure is reduced, gases are desorbed and flow

h llb l k f f ( l )to the wellbore via a natural network of fractures (cleats).After gas arrives at the wellbore, it is produced utilizingconventional hydrocarbon gas extraction technology

‐ Slow initial desorption and relative permeability effectscreate a “negative gas decline curve.” Unique productioncharacteristics of CBM results in low but inclining initial gasproduction, peaking around 4‐6 years as the coal isd d (d i d)

GAS CONTENT CALCULATION

Formula Kim (1977)

G = 32 x (1-a-m) x 0.75 x { ko x (0.096d)no – 0.14 x( 1.8d/100) + 11)} Rf

G = Gas content (sct/ton)( )a = ash content (%)m = moisture content (IM)fc = fixed carbón (%)fc = fixed carbón (%)vm = volatile matter (%)d = depth of coal seam (feet)ko = 0.8 (fc/vm)+5.6no = 0.39 – 0.013 koRf = recovery factor (%) Coal Cutoffy f

range Rf : 50% – 85%Coal Cutoff • 300 – 1500 m (depth)• ≥1.5m (thickness)

Recovery FactorRecovery FactorEstimating 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 forRecovery factor might be 50% to 85%


DRILLING

‐ CBM drilling basically similar to oil and gas conventional, except keeping the drilling cost as low as possiblein order to achieve economics of the project since typical CBM development needs massive number ofwells. In order to do so safe and creative approaches in CBM drilling is strongly recommended.
