Abstract
A production system placed inside a wellbore has a production tubing and an ESP for flowing fluid from the wellbore into the production tubing. A sensor string including distributed sensors is placed along the sensor string and provides temperature measurements along the production tubing uphole of the ESP. A controller determines from the temperature measurements a change in temperature that exceeds a threshold and determines therefrom level of a liquid in the wellbore.
