  • Actuation dart for wellbore operations, wellbore treatment apparatus and method
    Patent number: 10408018
    Abstract: A wellbore assembly including an actuation dart for actuating a target tool in tubing string. The dart is activatable downhole, such that it can be moved past tools similar to the target tool without actuating them. The target tool may include a release mechanism that releases the actuation dart after being actuate by it. Such a target tool may be useful with a second tool that retains the actuation dart against further movement down the tubing string.
