receiving well data comprising an orientation of the cased well;
selecting a logging while levitating (LWL) assembly type based on the well data;
running the LWL assembly into the well to a start depth;

wherein levitating comprises contactless hovering in the center of the cased well;
determining whether the LWL assembly has reached a target depth; and
performing logging in the cased well while the LWL assembly is levitating in the cased well when the target depth is reached.
