method of characterization of materials disposed in the wellbore; and, wellbore profiling system.

摘要

One method includes introducing a tool set into a wellbore having an annular material disposed in a defined annular space between the casing and the wellbore. obtaining acoustic refracted waveform measurements of the annular material from a cement adhesion profiling tool, obtaining ultrasound measurements of the annular material from a circumferential acoustic scanning tool, obtaining radiation measurements gamma scattered from the annular material from a spectral density profiling tool, and obtaining thermal neutron radiation measurements scattered from the annular material from a doubly spaced neutron profiling tool. The obtained measurements can then be collected and calculated with a computer and a delivery is generated, which includes one or more cross-sectional graphs that provide an equivalent of the composition of the annular material.
