Abstract

Some methods of scale and corrosion monitoring of a well include receiving information from a plurality of transducers disposed in a ring on a circumference of a tubing of the well, the received information including frequency domain information representing a first longitudinal ultrasonic wave and a first torsional ultrasonic wave to arrive at the plurality of transducers; determining arrival times for the first longitudinal ultrasonic wave and the first torsional ultrasonic wave to arrive at the plurality of transducers based on the received information; comparing the determined arrival times with a range of predetermined arrival times from a model that accounts for wave refraction using a ray tracing scheme to determine a wall thickness of the tubing, a scale thickness of scale within the tubing, and a scale shear wave velocity of the scale; and identifying a material of the scale based on the determined scale shear wave velocity.
