A high energy explosive for gas and oil-well stimulation has been recently field tested in 103 wells. Blasting agents designed originally for open pit mining were modified into self-contained slurries, complete with encapsulated air, that can be safely placed through tubing. Blasting agents were placed with bailer or pressure displacement equipment on the last 75 of the 103 wells. For 60 wells with production data prior to explosive fracturing, 90% had increased production. Of total jobs, 75% were profitable. An outstanding feature of explosive stimulation is the random fracturing of formation rock around the well bore. This treatment may be most effective in hard, low permeability formations where hydraulic fracturing contacts a relatively small volume of rock. Several possible limitations should be considered: wells must be static with BHP less than 1,500 psi, bottom-hole temperature must be between 65$ and 250$F, and the formation must be exposed in open-hole.
