Weight setting indicator

摘要

The present invention generally relates to a weight setting indicator which is used to indicate that an applied force to a tool achieved or exceeded a predetermined amount. In one aspect, a packer actuator for use with a packer is provided. The packer actuator includes a body with a recess. The packer actuator further includes a dog assembly disposed in the recess of the body. The dog assembly is configured to set the packer when a force is applied to the packer actuator. The packer actuator also includes a setting indicator disposed in the recess adjacent an end of the dog assembly. The setting indicator is configured to move from a pre-set position to a post-set position when the force is applied to the packer actuator, wherein the setting indicator is plastically deformed in the post-set position.
