Abstract
Systems and methods for treating subterranean formations for treating subterranean formations using propellant fracturing and hydraulic fracturing to detonate and inject in sequential stages. A method comprises disposing a propellant fracturing tool downhole into a well bore; introducing a fracturing fluid into a work string coupled to the fluid conduit to pressurize and set an upper packer and a lower packer against the well bore; detonating sequentially a plurality of propellant band stages to produce one or more fractures; introducing sequentially a series of treatment fluids into a well bore penetrating at least a portion of a subterranean formation, wherein the sequential introduction of the series of treatment fluids occurs between the sequential detonation of the plurality of propellant band stages; and depositing at least a portion of the treatment fluids in at least a portion of the subterranean formation.
