Abstract
A device for actuating a downhole tool includes a housing having a surface structure on an external surface thereof. The surface structure has an inactive state and an activated state. In the inactive state, the device can travel through seat structures mounted in a well tubing and will experience a physical impact having an impact level exceeding a threshold level when passing through each one of the seat structures. In the activated state, the device can seat in a selected seat in the well tubing. A sensor is enclosed in the housing and configured to generate a signal in response to the physical impact. A controller in the housing communicates with the impact sensor and monitors the physical impacts; and activates the surface structure based on the monitored physical impacts.
