Abstract: A method of stimulating production of coalbed methane involves providing a perforation charge comprising a standard charge portion and a charge additive able to produce localized temporary oxidizing environments in perforations. A coal-bearing formation is perforated with the perforation charge to form initial perforations defined by carbonaceous material. The initial perforations have localized temporary oxidizing environments in them. Combustion of the carbonaceous material is initiated using the oxidizing environments, thus enlarging the initial perforations. Other methods involve perforating the coal-bearing formation with a standard perforation charge, thereby creating perforations. The perforations are treated with a composition creating temporary local oxidizing environments involving an oxidant in the perforations. Combustion of carbonaceous material is initiated using the excess oxidant, thus enlarging the perforations.

Abstract: A method is disclosed for generating a wellsite design, comprising: designing a workflow for an Earth Model; building an initial Earth Model based on the workflow adapted for modeling drilling and completions operations in a hydrocarbon reservoir; calibrating the initial Earth Model thereby generating a calibrated Earth Model; and generating the wellsite design using the calibrated Earth Model.

Abstract: Herein is disclosed a well completion or stimulation fluid, comprising (i) a carrier fluid; (ii) a viscoelastic surfactant; and (iii) a fluid loss control additive (FLA) comprising at least one polymer and at least one crosslinker. The fluid may further comprise proppant or gravel, if it is intended for use as a fracturing fluid or a gravel packing fluid, although such uses do not require that the fluid comprise proppant or gravel. Also disclosed herein are methods of fracturing a subterranean formation, comprising (i) providing a fracturing fluid discussed above and (ii) injecting the fracturing fluid into the formation at a pressure sufficiently high to fracture the formation. In addition, disclosed herein are methods of gravel packing a wellbore, comprising (i) providing a gravel packing fluid discussed above and (ii) injecting the gravel packing fluid into the wellbore.
