When an ESP failure occurs, it is critical to understand the failure mechanism so repeat failures can be avoided. A thorough DIFA with an experienced third party is the best means of achieving this goal. ALS provides this service for customers around the world, seeking not only to understand the mode of failure, but also to determine the Root Cause and provide recommendations on how to mitigate the issues encountered, thus prolonging runlife. No DIFA is complete unless a Root Cause is pursued, so Root Cause Failure Analysis is the ultimate objective of every DIFA that ALS performs.
