1. A method comprising:

  • (a) providing a wellbore able to access a coal-bearing formation;

    (b) providing a perforation charge comprising a standard charge portion and a composition able to produce localized temporary oxidizing environments in perforations;

    (c) perforating the coal-bearing formation through the wellbore with the perforation charge to form initial perforations defined by carbonaceous material, the initial perforations having localized temporary oxidizing environments therein; and

    (d) initiating combustion of the carbonaceous material using the oxidizing environments, thus enlarging the initial perforations.
