Data Reduction
Inclination Measurements The inclinometer probe and the in-place sensor measure the tilt of
the casing. With the probe, inclination measurements are typically
taken at half-meter or 2-foot intervals from the bottom to the top of
the casing. In-place sensors are installed at fixed positions in the
casing at one-meter or larger intervals. In either case, the tilt reading
is associated with a depth or elevation.
Lateral Deviation When inclinometer readings are processed, tilt is converted to a
lateral distance, as shown below. Deviation at each interval is called
incremental deviation. The sum of incremental deviations is called
cumulative deviation.
Deviations represent the position of the casing. A plot of cumulative
deviations shows the profile of the casing.
