The effect of magmatic intrusions on reservoir characteristics of the Hoskissons coalbed in the Gunnedah Basin is studied.
The position of magmatic intrusions with respect to the coal interval is investigated by wellbore data.
Borehole image logs and drill stem tests are used to study the quality of natural fracture/cleat system.
Gas content and its quality are studied by available desorption canister and gas composition data.
The effect of hydrothermal circulations derived either from intrusions or coal itself on coal permeability is studied.
