1. 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.
