1. A method for logging in a well, comprising:
securing a passive logging while levitating (PLWL) assembly to a bottomhole assembly (BHA) to form a logging assembly;
running the logging assembly into a wellbore of the well;
detecting a deviation in the wellbore;
detecting a fluid flow direction around the logging assembly in the wellbore;
activating the PLWL assembly based, at least in part, on the deviation in the wellbore and the fluid flow direction, wherein activating the PLWL assembly comprises adjusting an orientation of a plurality of wings disposed on the PLWL assembly based, at least in part, on the deviation in the wellbore and the fluid flow direction;
levitating the logging assembly in a center of the wellbore;
determining whether the logging assembly has reached a target depth; and
performing logging in the well while the logging assembly is levitating in the center of the wellbore,
wherein adjusting the orientation of the plurality of wings comprises causing a deflection of fluid flow in the wellbore and initiating a lifting force on the logging assembly.
