Abstract

The secondary recovery of petroleum by hydraulic fracturing of wells is much improved by blasting. Pairs of detonators are arranged between packs of explosives in such a way that two simultaneous explosions are triggered in two different planes. Where the shock waves meet, a pressure peak is built up which induces the formation of a fracture in the strata.
