Pipe Deformation Analysis (PDA)
Our deformation analysis is based on:
Analysing Caliper Data
Allows for tools to freely bend. A bend of 0.5° per 10m corresponds to an 80mm relative displacement of the distal portion.
Please see the examples below.

95mm OD Tool of 12m length with a 0.5° bending allowance per 10m could pass through the deformed casing.
107mm OD Tool of 7m length with a 1.5° bending allowance per 10m could pass through the deformed casing.

Fracking sleeve view in corrosion image log and vertical profile view.
The vertical profile view shows a starting width of 100mm and the caliper determines a pit depth of 35mm outside through the casing wall.

We can detect deformation of any calibre. Depending on the AER severity class (1 through 4), the consequences of a deformed pipe can lead to serious environmental contamination and production loss.
