Abstract
Methods and systems are provided for fracturing rock in a formation to enhance the production of fluids from the formation. In one exemplary method, one or more wells are drilled into a reservoir, wherein each well comprises a main wellbore with two or more lateral wellbores drilled out from the main wellbore. One or more explosive charges are placed within each of the two or more lateral wellbores, and the explosive charges are detonated to generate pressure pulses which at least partially fracture a rock between the two or more lateral wellbores. The detonations are timed such that one or more pressure pulses emanating from different lateral wellbores interact.
