Stimulating wells with liquid explosives
This is a method for increasing the permeability of underground formation adjacent to a well bore by explosive fracturing. This invention relates especially to a special method of placing the liquid explosive in the well. It includes setting a plugged packer in the well just above the formation to be stimulated. A tubing string is run in the well with the lower end just above the plugged packer. The selected amount of liquid explosive is then forced into the tubing string. After this, the tubing string is inserted in the packer and the plug of the packer is removed. The explosive is then forced downward into the well bore. The packer is replugged, tubing is removed, and the well bore is stemmed. The detonation is then effected. (15 claims)
