1. A wellbore assembly comprising:
a cable disposed within a wellbore and extending from or near a surface of the wellbore to a downhole end of the cable; and
a wellbore tool coupled to the downhole end of the cable and suspended on the cable, the wellbore tool comprising:
a housing coupled to the cable,
one or more sensors coupled to the housing or the cable or both and responsive to one or more parameters of the wellbore tool or the cable or both, the one or more parameters comprising at least one of an acceleration of the wellbore tool, an angular velocity of the wellbore tool, a tilt angle of the wellbore tool, or a tension of the cable;
a packer; and
a controller coupled to the housing, the controller electrically coupled to the one or more sensors and operationally coupled to the packer, the controller configured to determine, with the wellbore tool separated from a first portion of the cable and based on feedback received from the one or more sensors, an indication of the wellbore tool in free fall, the controller configured to activate, based on the determination, the packer to expand the packer and set the wellbore tool on a wall of the wellbore;
wherein the controller is configured to determine, based on the sensor feedback, that the tension of a second portion of the cable attached to the wellbore tool is zero, and the controller is configured to activate the packer based on the determination that the tension is zero.
