This paper presentation introduces a forensic workflow that may be used to link drill bit and bottom hole assembly (BHA) damage to drilling dysfunction. It also discusses what data should be collected and how it should be processed to enable the operational practices and engineering design changes to address these issues. 

Several drilling forensic case studies were developed and critically reviewed by subject matter experts from across the industry. By combining the learnings from these case studies, it was observed that a guided approach can improve data collection and lead to a more consistent, accurate, timely causal analysis with appropriate remedial actions. Practical guidelines have been developed to offer a foundation for a drilling forensic data collection methodology as well as training for the industry. 

This presentation is from the 2022 IADC/SPE International Drilling Conference and Exhibition.
