Abstract:
1. A method of fracturing a geological formation, comprising the steps of: pre-determining the location of a pattern of boreholes in or proximate the geological formation wherein said step of pre-determining the location of a pattern of boreholes in or proximate the geological formation includes pre-determining the location of a main borehole in or proximate the geological formation and pre-determining the location of side boreholes extending from said main borehole in or proximate the geological formation, drilling said pattern of boreholes into or proximate the geological formation wherein said step of drilling said pattern of borehole into or proximate the geological formation includes drilling said main borehole into or proximate the geological formation and drilling said side boreholes extending from said main borehole into or proximate the geological formation, emplacing energetic charges in said boreholes, isolating said side boreholes from said main borehole by cementing off said side boreholes from said main borehole, and detonating said energetic charges and fracturing the geological formation.
