## Abstract

A flat pack (1) for operating a downhole tool or sensor includes a plurality of tubes (3a, 3b); a spacer (2) disposed between the tubes (3a, 3b); and a jacket (4) encapsulating the tubes (3a, 3b) and the spacer (2). The tubes (3a, 3b) and the spacer (2) are positioned in the jacket (4) in a side-by-side arrangement. The tubes (3a, 3b) and the spacer (2) are not twisted along the flat pack (1).

## Claims

### Claim 1

A flat pack for operating a downhole tool or sensor, comprising:
a plurality of tubes;
a spacer disposed between the tubes; and
a jacket encapsulating the tubes and the spacer, wherein the tubes and the spacer are positioned in the jacket in a side-by-side arrangement, and the tubes and the spacer are not twisted along the flat pack.

### Claim 2 (depends on 1)

The flat pack of claim 1, wherein the tubes are each metallic.

### Claim 3 (depends on 1)

The flat pack of claim 1, wherein the spacer is made from a thermoset polymer having sufficient flexibility so that the flat pack is spoolable.

### Claim 4 (depends on 1)

The flat pack of claim 1, wherein the jacket is made from a thermoplastic polymer, a thermoplastic copolymer, or a thermoplastic elastomer.

### Claim 5 (depends on 1)

The flat pack of claim 1, wherein spacer has a top, a bottom, and concave sides receiving portions of outer surfaces of the tubes.

### Claim 6 (depends on 5)

The flat pack of claim 5, wherein a height of the spacer matches a diameter of at least one of the tubes, and a minimum width of the spacer is at least one millimeter.

### Claim 7 (depends on 5)

The flat pack of claim 5, wherein a top of the spacer is flat or slightly curved, a bottom of the spacer is flat or slightly curved, and a curvature of each concave side matches a curvature of the respective tube.

### Claim 8 (depends on 7)

The flat pack of claim 7, wherein a diameter of one of the tubes is greater than a diameter of the other tube

### Claim 9 (depends on 7)

The flat pack of claim 7, wherein the concave sides of the spacer are asymmetric.

### Claim 10 (depends on 5)

The flat pack of claim 5, wherein a cross-section of the spacer resembles an hourglass shape.

### Claim 11 (depends on 5)

The flat pack of claim 5, further comprising a tear cord disposed in a guide formed in the top or bottom of the spacer.

### Claim 12 (depends on 11)

The flat pack of claim 11, wherein the tear cord is an upper tear cord

### Claim 13 (depends on 11)

The flat pack of claim 11, wherein the guide is an upper guide formed in the top of the spacer.

### Claim 14 (depends on 11)

The flat pack of claim 11, further comprising a lower tear cord disposed in a lower guide formed in the bottom of the spacer.

### Claim 15 (depends on 1)

The flat pack of claim 1, wherein one of the tubes is a flowline.

### Claim 16 (depends on 1)

The flat pack of claim 1, wherein one of the tubes is part of a tubing encased conductor.

### Claim 17 (depends on 1)

The flat pack of claim 1, wherein one of the tubes is part of a tubing encased optical cable.

### Claim 18 (depends on 1)

The flat pack of claim 1, further comprising a pair of bumpers, and second and third spacers disposed between a respective tube and a respective bumper, wherein the jacket also encapsulates the bumpers and the second and third spacers.

### Claim 19

A line for operating a downhole tool or sensor, comprising:
a tube;
a tear cord;
a spacer having a top, a bottom, a concave side receiving a portion of an outer surface of the tube, and a flat side having a guide receiving the tear cord; and
a jacket encapsulating the tube, the spacer, and the tear cord, wherein the tube and the spacer are not twisted along the line.

### Claim 20

A flat pack for operating a down hole tool or sensor, comprising:
a tube;
a pair of bumpers;
a pair of spacers disposed between the tube and the bumpers; and
a jacket encapsulating the tube, the bumpers, and the spacers, wherein the tube, the spacers, and the bumpers are positioned in the jacket in a side-by-side arrangement, and the tube and the spacers are not twisted along the flat pack.
