Abstract
Well perforation methods of the present disclosure may comprise introducing a perforation bullet into a wellbore comprising a well casing, the wellbore penetrating a subterranean formation; wherein the perforation bullet comprises a housing; an explosive within the housing, the explosive comprising amorphous porous silicon; and an igniter within the housing physically separated from the explosive, the igniter comprising a nitrate; and exposing the explosive to the igniter to induce a detonation to produce a plurality of perforations within the well casing, thereby allowing fluid communication between the subterranean formation and the wellbore.
Claims16
A system comprising:
- a housing;
- an explosive within the housing, the explosive comprising amorphous porous silicon having a total surface area of about 450 m2/g to about 600 m2/g;
- an igniter within the housing physically separated from the explosive, the igniter comprising a nitrate;
- and
- a detonator cord in communication with the igniter and not contacting the explosive.
A method comprising:
- introducing a perforation bullet into a wellbore comprising a well casing, the wellbore penetrating a subterranean formation;
- wherein the perforation bullet comprises:
- a housing;
- an explosive within the housing, the explosive comprising amorphous porous silicon having a total surface area of about 450 m2/g to about 600 m2/g;
- an igniter within the housing physically separated from the explosive, the igniter comprising a nitrate;
- and
- a detonator cord in communication with the igniter and not contacting the explosive;
- and
- exposing the explosive to the igniter to induce a detonation to produce a plurality of perforations within the well casing, thereby allowing fluid communication between the subterranean formation and the wellbore.
