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.

Abstract: In one aspect, a production system is disclosed that in one embodiment may include a production tubing placed inside the wellbore, an ESP in the wellbore for flowing fluid from the wellbore into the production tubing, a sensor string including distributed sensors along the sensor string that provides temperature measurements along the production tubing uphole of the ESP, and a controller that determines from the temperature measurements a change in temperature that exceeds a threshold and determines therefrom level of a liquid in the wellbore.

Abstract: A wet disconnect system with post disconnection pressure integrity includes a bridge tube. One or more seals on the bridge tube that seal the bridge tube to one or more conductors passing through the bridge tube. A defeatable seal/anchor at the bridge tube sealing an outside surface of the bridge tube to an inside surface of a separate structure. The defeatable seal/anchor being defeatable upon application of an axial load above a threshold.
