A method of performing a wellbore operation includes: circulating a doped wellbore fluid comprising a non-radioactive doped particulate material in a wellbore; and logging the wellbore with a logging-while-drilling tool to determine at least one characteristic of the doped wellbore fluid. A method of performing a wellbore operation includes: circulating a doped wellbore fluid comprising a non-radioactive doped particulate material in a wellbore; logging the wellbore with a logging tool; and determining a location of at least one fracture by elemental spectroscopy measurements.
