Abstract
Some implementations include an apparatus comprising an explosive material configured to detonate; a liner in contact with the explosive material, the liner configured to, after detonation of the explosive material, form jets to perforate a tubular disposed in a subsurface borehole; a reactive material configured to release energy in response to detonation of the explosive material; and a case in contact with a portion of the reactive material and configured to surround the explosive material, the liner, and the reactive material.
Claims11
An apparatus comprising:
- an explosive material configured to detonate;
- a liner in contact with the explosive material, the liner configured to, after detonation of the explosive material, form jets to perforate a tubular disposed in a subsurface borehole;
- a reactive material configured to release energy in response to detonation of the explosive material;
- and
- a case with a conoidal shape in contact with the liner and a portion of the reactive material and configured to surround the explosive material, the liner, and the reactive material, wherein a thickness of the reactive material increases as the reactive material spans from an orifice at an apex of the conoidal shape substantially to a base of the conoidal shape.
A system comprising:
- one or more shaped charges each including an explosive material configured to detonate,
- a liner in contact with the explosive material, the liner configured to, after detonation of the explosive material, form jets to perforate a tubular disposed in a subsurface borehole,
- a reactive material configured to release energy in response to detonation of the explosive material, and
- a case with a conoidal shape in contact with the liner and a portion of the reactive material and configured to surround the explosive material, the liner, and the reactive material, wherein a thickness of the reactive material increases as the reactive material spans from an orifice at an apex of the conoidal shape substantially to a base of the conoidal shape;
- and
- a perforation device configured to operate with the shaped charge to perforate the tubular in the subsurface borehole.
A method comprising:
- inserting one or more shaped charges into a tubular inside a borehole, each shaped charge including a reactive material configured to release energy in response to detonation of an explosive material in contact with the liner, wherein the reactive material is in contact with a case with a conoidal shape that is in contact with the liner, wherein the case surrounds the explosive material, the liner, and the reactive material, and wherein a thickness of the reactive material increases as the reactive material spans from an orifice at an apex of the conoidal shape substantially to a base of the conoidal shape;
- and
- detonating the explosive material to perforate the tubular.
