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.
Claims18
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.

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.
