Abstract
A method for treating a hydrocarbon bearing formation bounded by at least one nonbearing formation comprises inserting a tubular into a wellbore formed in the hydrocarbon bearing formation. The tubular defines proximal and distal ends and further has a sidewall defining inner and outer surfaces and a tubular bore, where an annulus is defined between the outer surface of the sidewall and the inner surface of the wellbore. A detonator is disposed in the annulus through at least a portion of the hydrocarbon bearing formation. A first fluid including a first explosive is pumped through the tubular bore into a selected portion of the annulus. An isolation material is inserted in the annulus between an entrance of the wellbore and the first explosive fluid. The explosive fluid is detonated with the detonator.
