Explosive fracturing and propping of petroleum wells

Patent ·
OSTI ID:5306355
A method is described of stimulating the flow of petroleum fluids in a well. Explosive fracturing of the petroleum formation adjacent to the well is carried out in the presence of a propping agent, such as glass beads, sand or aluminum particles. The propping agent-explosive combination is preferably surrounded by granular ammonium nitrate explosive to insure the absence of voids in the well bore. The method avoids the necessity for the use of liquids for fracturing or propping, and this is advantageous in cases where the formation would be damaged by the use of liquids such as water or drilling fluids.
