This disclosure relates to a method to facilitate the extraction of hydrocarbon from a coal seam gas formation. In one aspect, the method comprises steps of: (a) drilling a wellbore using a drill string to access the coal seam gas formation; (b) perforating a section of the drill string; (c) abandoning a section of the drill string in the wellbore; (d) setting a temporary plug to isolate the abandoned section of the drill string and the wellbore; (e) installing a production tubing string above the temporary plug, so as to create a fluid passageway to facilitate the extraction of hydrocarbon; (1) displacing a fluid above the temporary plug, so as to create a high pressure differential; (g) removing the temporary plug, so as to create an initial stimulated reservoir volume to extract hydrocarbon from the coal seam gas formation and, resultantly, at least partially filling an annulus formed between the abandoned section of the drill string and the wellbore wall with coal fragments; and (h) continuing to extract hydrocarbon from the coal seam gas formation via the fluid passageway, at a high pressure drawdown, so as to create an expanding stimulated reservoir volume.
