摘要 |
A method for activating a shifting tool comprises introducing a shifting tool in a desired wellbore zone where it is exposed to a pre-determined hydrostatic pressure. The shifting tool comprises at least one key that is configured to be expanded and released from a retracted position when the shifting tool is subjected to the pre-determined hydrostatic pressure. |
