Wellbore deposition monitoring tool

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
