Abstract
A method for generating a horizontal fracture through a wellbore by causing two explosively induced shear waves to intersect. This is achieved by placing, within a coupling fluid within a wellbore, a length of high explosives whose center is adjacent the location where a fracture is desired. Both ends of the high explosive are ignited simultaneously.
