Claim:
1. A system for fracturing an underground geologic formation adjacent to a wellbore, comprising: a plurality of explosive units comprising a casing, a detonator, and an explosive material contained within the casing; and one or more detonation control modules electrically coupled to the plurality of explosive units, each detonation control module comprising a high-voltage capacitor module, an optical diode module, and a timing and triggering module, and configured to cause a power pulse to be transmitted to at least one detonator of at least one of the plurality of explosive units for detonation of the explosive material; wherein the explosive units are configured to be positioned within a wellbore in spaced apart positions relative to one another with the one or more detonation control modules positioned adjacent to the plurality of explosive units in the wellbore; and wherein the one or more detonation control modules are configured to be remotely controlled from a location outside of the wellbore in order to detonate the plurality of explosive units within the wellbore in a predetermined manner.
