  • Patent number: 4764231
    Abstract: Well stimulation involving use of a liquid explosive composition in the explosive fracturing of subterranean formations such as oil and gas bearing formations. An explosive formulation comprising a nitrate ester explosive component and a phlegmatizer component is introduced into a well penetrating the formation to be fractured. The phlegmatizer component is an alkyl or alkoxy diester which is mixable with the nitrate ester and can be varied in concentration to control the detonation velocity and maximum explosive pressure. Examples of phlegmatizing agents include alkyl or alkoxy alkyl esters of adipate or azelaic acids such as dibutoxyethyl adipate or diisobutyl azelate or polyethylene glycoxy-based diesters such as triethylene glycol dipelargonate. After the formulation is detonated to fracture the formation, the well is placed on production to recover hydrocarbons at an increased rate.

  • Patent number: 4718953
    Abstract: A novel heterogeneous, cap-sensitive high explosive is provided which comprises a crystalline inorganic nitrate salt having dispersed throughout the matrix of the salt crystal a hydroxyalkyl nitrate fuel. Particularly preferred are ammonium nitrate crystals having dispersed therein ethylene glycol mononitrate. The crystalline high explosive is dry and free flowing and may be used per se, in admixture with bulking agents or fluidizing agents or may be used as a replacement for a substantial amount of nitroglycerine in conventional dynamite compositions.
