Early Production From Some Devonian Shale Gas Wells Stimulated With Several Kinds of Explosive Charge

Abstract

Early cumulative production from Devonian Shale gas wells stimulated with a high energy water gel explosive averaged 2 times that from nearby wells stimulated with dynamite.From an estimate of production loss due to well damage done by post-shot drilling in the shot zone, it is concluded that production from the wells stimulated with water gel would have averaged 5 times that from dynamite stimulations if no such drilling had been done.It releases an expansion energy per unit mass that is about twice that of dynamite. This doubling of both the expansion energy per unit mass and the mass per unit length of hole means that the energy applied to the rock can be approximately four times that from a charge of dynamite.
