Abstract

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.

Claims (42)

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.

2 . The shaped charge of claim 1 wherein the tracers are radioactive chemicals with specific miscibility in organic and inorganic fluids.

3 . The shaped charge of claim 1 wherein the tracers are synthetic nano-particles, radioactive, chemicals with specific miscibility in organic and inorganic fluids, rare-earth oxides,) synthetic nanocrystals, or quantum dots.

4 . The shaped charge of claim 1 wherein the tracers are identifiable within production fluid at a surface of the well after flowing back in the production fluid.

5 . The shaped charge of claim 4 wherein the tracer is identifiable using an in-flow device containing a collimated laser.

6 . The shaped charge of claim 4 wherein the tracers are monitorable using a flow through device using sampling and inductively coupled plasma (ICP) mass spectrometry device.

7 . The shaped charge of claim 4 wherein the tracers are identifiable using a Geiger-Müller detector.

8 . The shaped charge of claim 1 wherein the tracers are present in fluid as colloidal particulates, and wherein the tracers have one or more of the following fluid characteristics: surface adhering, matrix mixing, impregnating, adsorbing, or absorbing in a permeable and porous scaffold.

9 . The shaped charge of claim 1 wherein the tracers are one or more of a rare-earth doped oxide, sulfide and halide nanocrystals that emit light of a predetermined frequency when illuminated by a laser.

10 . The shaped charge of claim 1 wherein the tracers manifest identifiable emission and absorption spectra and decay times based on at least one of their optical, physical, magnetic, radioactive, and luminescent properties.

11 . The shaped charge of claim 1 wherein the tracers have a precise crystallite size identifiable by a corresponding spectroscopic or optical detector.

12 . The shaped charge of claim 1 , further comprising a computing system configured to store and relay information remotely relating to identifying the tracers with the production fluid.

13 . The shaped charge of claim 1 wherein the tracers are configurable to be identifiable according to a provider of the tracers.

14 . The shaped charge of claim 1 wherein the tracers are integrated to the liner using additive manufacturing.

15 . 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; and

a powdered additive complex comprising a bulk metallic glass composite (BMGC) material;

wherein, upon detonation of the shaped charge a perforation tunnel is formed in a casing and into a formation in a well.

16 . The shaped charge of claim 15 , further comprising tracers for distinction and targeted identification, wherein detonation deposits the tracers in the perforation tunnel, and wherein the tracers flow back with production fluid through the perforation tunnel.

17 . The shaped charge of claim 16 wherein the tracers are absorbable in activated carbon or may be free flowing powder or a nano particulate.

18 . 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; and

a powdered additive complex comprising a high entropy alloy (HEA) material;

wherein, upon detonation of the shaped charge a perforation tunnel is formed in a casing and into a formation in a well.

19 . The shaped charge of claim 18 , further comprising tracers for targeted identification wherein the tracers are absorbable in activated carbon or are free flowing powder or a nano particulate.

20 . The shaped charge of claim 18 further comprising tracers for targeted identification wherein detonation deposits the tracers in the perforation tunnel, and wherein the tracers flow back with production fluid through the perforation tunnel.
