A method of servicing a wellbore, comprising placing a plurality of Micro-Electro-Mechanical System (MEMS) sensors in a wellbore composition, pumping the wellbore composition into the wellbore at a flow rate, determining velocities of the MEMS sensors along a length of the wellbore, and determining an approximate cross-sectional area profile of the wellbore along the length of the wellbore from at least the velocities of the MEMS sensors and the fluid flow rate. A method of servicing a wellbore, comprising placing a plurality of Micro-Electro-Mechanical System (MEMS) sensors in a wellbore composition, pumping the wellbore composition into the wellbore, determining positions of the MEMS sensors relative to one or more known positions along a length of the wellbore, and determining an approximate cross-sectional area profile of the wellbore along the length of the wellbore from at least the determined positions of the MEMS sensors.
