Perforating stimulating bullet

1. A charge device for use in fracturing formation adjacent a wellbore comprising:

a housing;

an explosive in the housing; and

a bullet assembly in the housing comprising

a jacket having a forward end, a rearward end, and sidewalls between the forward end and rearward end that define a cavity within,

energetic material disposed in the cavity and energetic energy that is disposed within material of the jacket, and

a delay fuse in selective communication with the energetic material, so that a detonation wave forms and directs the bullet assembly into the formation when the explosive in the housing is detonated and a reaction of the energetic material is initiated by the delay fuse when the bullet assembly is in the formation to form a fracture in the formation.

2. The charge device of claim 1 , wherein energetic material is housed in the jacket with the explosive, and wherein the energetic material is selected from the group consisting of a propellant, an oxidizer, and combinations thereof.

3. The charge device of claim 1 , wherein the delay fuse is ignited by communication with the explosive.

4. The charge device of claim 1 , further comprising a seal ring that seals an annular space between the jacket and housing.

5. The charge device of claim 4 , wherein a perforation is formed into the formation when the bullet assembly is projected into the formation and the seal ring provides a pressure barrier between the bullet assembly and an inner surface of the perforation.

6. The charge device of claim 1 , wherein the forward end comprises an outer surface with a score so that the forward end is frangible, and so that when expanding gases are produced by initiating the energetic material, pressure from the expanding gases fractures the forward end and is directed into the formation through the forward end.

7. The charge device of claim 1 , wherein the energetic material comprises a substance selected from the group consisting of an oxidizing agent, a propellant, and combinations thereof.

8. The charge device of claim 1 , further comprising a rear wall disposed in an opening in the rearward end of the jacket, wherein the rear wall separates the explosive from the energetic material in the cavity.

9. A method of fracturing a subterranean formation comprising:

a. providing a bullet assembly comprising a jacket made from a material that comprises an energetic material, a cavity in the jacket, energetic material in the cavity, and a delay fuse;

b. disposing the bullet assembly in a wellbore;

c. detonating an explosive to launch the bullet assembly from the wellbore a distance into the formation thereby producing a perforation in the formation; and

d. reacting the energetic material after the bullet assembly is launched a distance into the wellbore to generate pressure within the formation to generate an elongated fracture in the formation that extends past an end of the perforation.

10. The method of claim 9 , wherein the bullet assembly is part of a charge device that is set within a perforating gun.

11. The method of claim 9 , wherein the energetic material comprises a substance selected from the group consisting of an oxidizing agent, a propellant, high explosives, and combinations thereof.

12. The method of claim 9 , wherein a force generated by the bullet assembly impacting the formation is transferred into the bullet assembly for reacting the energetic material.

13. The method of claim 9 , further comprising sealing between the bullet assembly and the perforation.

14. The method of claim 9 , wherein the energetic material is reacted when the bullet assembly reaches an end of the perforation.
