## Abstract

A downhole tool includes a shifting device and a load-monitoring sensor positioned above the shifting device. A distance between the shifting device and the load-monitoring sensor is less than or equal to about 10 m.

## Claims

### Claim 1

A downhole tool, comprising:
a shifting device;
a load-monitoring sensor positioned above the shifting device, wherein a distance between the shifting device and the load-monitoring sensor is less than or equal to about 10 m,
wherein the load-monitoring sensor is configured to measure an amount by which a load on the downhole tool changes in response to the shifting device contacting a restriction in a wellbore,
wherein the load comprises an axial tension load, an axial compression load, a rotational load, or a combination thereof; and
a body having a bore formed axially-therethrough and a recess formed in an outer surface thereof, wherein the load-monitoring sensor is positioned at least partially within the recess.

### Claim 2 (depends on 1)

The downhole tool of claim 1, wherein the restriction comprises a sleeve in the wellbore.

### Claim 3 (depends on 1)

The downhole tool of claim 1, wherein the restriction comprises a reduced cross-sectional area in the wellbore, a bend in the wellbore, or debris in the wellbore.

### Claim 4 (depends on 1)

The downhole tool of claim 1, further comprising a memory module positioned within the recess, wherein data representing the amount by which the load on the downhole tool increases or decreases is stored in the memory module.

### Claim 5 (depends on 1)

The downhole tool of claim 1, wherein the body is eccentric.

### Claim 6 (depends on 1)

The downhole tool of claim 1, further comprising:
a memory module positioned radially-inward from an inner surface of the body; and
a plurality of circumferentially-offset radial support members extending between the body and the memory module, wherein the axial bore is positioned circumferentially-between two of the radial support members.

### Claim 7 (depends on 1)

The downhole tool of claim 1, wherein the body is coupled to the shifting device.

### Claim 8 (depends on 1)

The downhole tool of claim 1, wherein the load-monitoring sensor comprises a strain gauge.

### Claim 9 (depends on 1)

The downhole tool of claim 1, wherein the load-monitoring sensor comprises a load cell.

### Claim 10 (depends on 1)

The downhole tool of claim 1, wherein the downhole tool is configured to be coupled to a drill string comprising a physical property sensor.

### Claim 11 (depends on 1)

The downhole tool of claim 1, wherein the physical property sensor measures at least one of pressure, temperature, and a wellbore trajectory.

### Claim 12

A downhole tool, comprising:
a shifting device;
a first load-monitoring sensor positioned above the shifting device, wherein a first distance between the shifting device and the first load-monitoring sensor is less than or equal to about 10 m,
a second load monitoring sensor positioned above the shifting device, wherein a second distance between the shifting device and the second load-monitoring sensor is less than or equal to about 10 m,
wherein the first and second load-monitoring sensors are configured to measure an amount by which a load on the downhole tool changes in response to the shifting device contacting a restriction in a wellbore,
wherein the load comprises an axial tension load, an axial compression load, a rotational load, or a combination thereof; and
a body having a bore formed axially-therethough and first and second recesses formed in an outer surface thereof,
wherein the first load-monitoring sensor is positioned at least partially within the first recess, and
wherein the second load-monitoring sensor is positioned at least partially within the second recess.

### Claim 13 (depends on 12)

The downhole tool of claim 12, wherein the first recess is circumferentially-offset from the second recess.

### Claim 14 (depends on 12)

The downhole tool of claim 12, wherein the restriction comprises a sleeve in the wellbore.

### Claim 15 (depends on 12)

The downhole tool of claim 12, wherein the restriction comprises a reduced cross-sectional area in the wellbore, a bend in the wellbore, or debris in the wellbore.

### Claim 16 (depends on 12)

The downhole tool of claim 12, further comprising a memory module positioned within the body, wherein data representing the amount by which the load on the downhole tool increases or decreases is stored in the memory module.

### Claim 17 (depends on 12)

The downhole tool of claim 12, wherein the body is eccentric.

### Claim 18 (depends on 12)

The downhole tool of claim 12, wherein the body is coupled to the shifting device.
