→Mechanical integrity logs
The well mechanical integrity survey logs include two groups. The first group, cement evaluation surveys, assesses the degree of cement fill around the casing and can be effective at locating potential channels for fluid movement. The second group is the casing inspection surveys, in which acoustic, mechanical, and electromagnetic measurements are used to evaluate internal and external casing conditions.

Cement evaluations are primarily done with cement bond logs or pulse-echo cement evaluation tools. These are acoustic devices whose main objectives are the measurement of cement annular fill around the casing.
