## Abstract

Composite cables suitable for use in conjunction with wellbore tools. One cable may include a polymer composite that includes dopants dispersed in a polymer matrix and continuous fibers extending along an axial length of the cable through the polymer matrix, wherein the cable is characterized by at least one of the following: (1) at least a portion of the cable having a density greater than about 2 g/cm3, wherein at least some of the dopants have a density of about 6 g/cm3 or greater, (2) at least a portion of the cable having a density less than about 2 g/cm3, wherein at least some of the dopants have a density of about 0.9 g/cm3 or less, (3) at least some of the dopants are ferromagnetic, or (4) at least some of the dopants are hydrogen getters.

## Claims

### Claim 1

A cable comprising:
a polymer composite that includes dopants dispersed in a polymer matrix and continuous fibers distributed through and contacting the polymer matrix, the continuous fibers also extending along an axial length of the cable through the polymer matrix, wherein the cable is characterized by at least one of the following:
(1) a first portion of the cable having a density greater than about 2 g/cm3, wherein a first portion of the dopants have a density of about 6 g/cm3 or greater,
(2) a second portion of the cable having a density less than about 2 g/cm3, wherein a second portion of the dopants have a density of about 0.9 g/cm3 or less,
(3) at least some of the dopants are ferromagnetic, and
(4) at least some of the dopants are hydrogen getters.

### Claim 2 (depends on 1)

The cable of claim 1, wherein the cable further comprises an energy conductor and the polymer composite is disposed about the energy conductor.

### Claim 3 (depends on 1)

The cable of claim 1, wherein the cable further comprises a sheath disposed about the polymer composite.

### Claim 4 (depends on 1)

The cable of claim 1, wherein the cable is characterized in that the density of the first portion of the cable is greater than about 2 g/cm3, and wherein at least some of the first portion of the dopants include at least one selected from the group consisting of: nickel, tungsten, cobalt, copper, cupronickel, lead, molybdenum, gold, platinum, palladium, silver, brass, bismuth oxide, iron, steel, stainless steel, tantalum, and any combination thereof.

### Claim 5 (depends on 1)

The cable of claim 1, wherein the cable is characterized in that the density of the second portion of the cable is less than about 2 g/cm3, and wherein at least some of the second portion of the dopants include at least one selected from the group consisting of: hollow glass microspheres, cenospheres, gases, a borate, carbon, nanotubes, graphite, graphene, fullerenes, and any combination thereof.

### Claim 6 (depends on 1)

The cable of claim 1, wherein the cable is characterized in that at least some of the dopants are ferromagnetic, and wherein at least some of the dopants include at least one selected from the group consisting of: nickel, a nickel alloy, cobalt, a cobalt alloy, iron, an iron alloy, steel, magnetite, hematite, a Heusler alloy, and any combination thereof.

### Claim 7 (depends on 1)

The cable of claim 1, wherein at least some of the dopants are magnetic.

### Claim 8 (depends on 1)

The cable of claim 1, wherein at least some of the dopants are superparamagnetic.

### Claim 9 (depends on 1)

The cable of claim 1, wherein the cable is characterized in that at least some of the dopants are hydrogen getters, and wherein at least some of the dopants include at least one selected from the group consisting of: titanium, nickel, zirconium, niobium, and any combination thereof.

### Claim 10 (depends on 1)

The cable of claim 1, wherein the cable is characterized in that at least some of the dopants are hydrogen getters, and wherein at least some of the dopants include at least one selected from the group consisting of: titanium, nickel, zirconium, niobium, and any combination thereof coated with at least one selected from the group consisting of: platinum, palladium, and any combination thereof.

### Claim 11 (depends on 1)

The cable of claim 1, wherein at least some of the dopants are fibers.

### Claim 12 (depends on 1)

The cable of claim 1, wherein the polymer composite includes dopants at about 1 vol % to about 75 vol % relative to the polymer matrix.
