First Claim
Patent Images
1. A method of correcting in-line inspection run data logs using acoustical data, comprising:
- positioning above ground markers periodically along a length of a pipeline to be inspected, the above ground markers generating detection events as an inspection tool passes;
positioning acoustic detectors periodically along the length of the pipeline;
causing an inspection tool to travel along the length of the pipeline;
creating an inspection log based on the detection events;
recording acoustic data generated by the inspection tool;
using the acoustic data to adjust the inspection log.

Abstract
A method of correcting in-line inspection run data logs using acoustical data includes positioning above ground markers periodically along a length of a pipeline to be inspected. The above ground markers generating detection events as an inspection tool passes. Acoustic detectors are positioned periodically along the length of the pipeline. An inspection tool travels along the length of the pipeline. An inspection log is created based on the detection events. Acoustic data generated by the inspection tool is recorded, and used to adjust the inspection log.
