US12460906 - Shaped charge liners with integrated tracers

A liner for a shaped charge having integrated tracers. The liner, when the associated shaped charge is detonated, does not create a plug, carrot, or residue in the created perforation tunnel. The liner includes integrated tracers that, after detonation, are scattered into the perforation tunnel and then begin to flow back in formation fluid flow and are identifiable in the flow.

The patent describes a shaped charge liner that incorporates integrated tracers, which are designed to be deposited in a perforation tunnel without leaving behind residue. Upon detonation, these tracers can flow back with production fluids, allowing for targeted identification in well formations.

Claim 1

1 . A shaped charge, comprising: a case having an interior volume; an explosive material in the interior volume of the case; and a liner in the interior volume, wherein the explosive material is between the liner and the case, wherein the liner is made from a powder complex comprising: a powdered copper-lead mixture; a powdered additive complex comprising at least one of a bulk metallic glass composite (BMGC) or a high entropy alloy (HEA) material; and tracers for distinction and targeted identification wherein the tracers are absorbable in activated carbon or may be free flowing powder or a nano particulate; wherein, upon detonation of the shaped charge a perforation tunnel is formed in a casing and into a formation in a well, wherein detonation deposits the tracers in the perforation tunnel, and wherein the tracers flow back with production fluid through the perforation tunnel. a case having an interior volume; an explosive material in the interior volume of the case; and a liner in the interior volume, wherein the explosive material is between the liner and the case, wherein the liner is made from a powder complex comprising: wherein the liner is made from a powder complex comprising: a powdered copper-lead mixture; a powdered additive complex comprising at least one of a bulk metallic glass composite (BMGC) or a high entropy alloy (HEA) material; and tracers for distinction and targeted identification wherein the tracers are absorbable in activated carbon or may be free flowing powder or a nano particulate; wherein, upon detonation of the shaped charge a perforation tunnel is formed in a casing and into a formation in a well, wherein detonation deposits the tracers in the perforation tunnel, and wherein the tracers flow back with production fluid through the perforation tunnel.
