Claim:
1. A method for recovering gases and/or liquids stored within one or more gas and/or liquid reservoirs, said method comprising the following steps: (a) locating an upper consolidated boundary of the one or more gas and/or liquid reservoirs; (b) drilling an access well which extends downwardly to at least adjacent the upper consolidated boundary of the one or more gas and/or liquid reservoirs; (c) drilling a section of the access well extending along or adjacent at least a portion of the consolidated upper boundary of the one or more gas and/or liquid reservoirs, wherein the section of the access well does not enter the one or more gas and/or liquid reservoirs; (d) creating permeability pathways from the section of the access well into the one or more gas and/or liquid reservoirs to enable the passive release of gas and/or liquid from the one or more gas and/or liquid reservoirs into the access well, the permeability pathways being created without drilling into the one or more gas and/or liquid reservoirs and using at least one of: (e) recovering the released gas and/or liquid through the access well.
