Abstract: A flow rate in a wellbore and a measured frictional pressure drop in the wellbore are used to determine a measured friction loss factor for the wellbore. The flow rate in the wellbore and an ideal frictional pressure drop in the wellbore are used to determine an ideal friction loss factor for the wellbore. A ratio of the measured friction loss factor and the ideal friction loss factor is used to monitor deposit buildup in the wellbore

Abstract: The present embodiments disclose a system and method for generating a predictive model to detect leak in undersea pipes. The system includes an administrator processor and one or more pipe sections. The method proceeds with observing changes in pressure, generating a predictive model configured to determine if a leak has occurred, and closing one or more pipes responsible for the leak.
