Abstract
In general, in one aspect, embodiments relate to a method and/or system that includes disposing a cement bond logging tool into a wellbore. The method and/or system comprising: a cement bond logging tool comprising: two or more transmitters configured to transmit an acoustic wave from cement bond logging tool; and an array of receivers configured to receive a refracted waveform; and an information handling system configured to process the refracted waveform from the array of receivers into a cement bond property log.

A system comprising:
- a cement bond logging tool comprising:
- two or more transmitters configured to transmit an acoustic wave from cement bond logging tool;
- and
- an array of receivers configured to receive a refracted waveform;
- and
- an information handling system configured to process the refracted waveform from the array of receivers into a cement bond property log utilizing at least some spiral sampling comprising comparing a baseline receiver with its nearest receiver.
