How does the data acquisition box work? 

The box is a data acquisition system that collects data applied to the algorithms (process) to detect the flaws in the casing before it fails. The algorithms come from data processing: filtering, selecting which parameters are providing the information, the magnitude of those values. When certain changes and features are detected during lab testing, it means that a flaw is occurring. Doing this analysis guides TWI to know what is important to look at to understand how the casing fails. The algorithm then gives instructions (flow diagrams, equations, limits, among others) showing the important steps and parameters to be followed to understand the flaw.

What is the purpose of the technology?

The purpose of the technology is to monitor well casing integrity for early detection of flaws before failure occurs, applying data processing algorithms and knowing the key parameters of the data collected with the technique what will allow detection. At the moment TWI discovered that the main parameters are vibration and possibly acoustic emissions, according to the results from the tests. These are the most promising techniques.

Field testings

Tests in St. Gallen (Switzerland) field site. Diverse lab tests at TWI facilities, including attenuation tests and fatigue resonance tests for all three techniques involve acoustic emissions, guided waves and vibration.
