Root Cause Analysis
When an incident occurs in the oilfield, it can impact many lives, both physically and financially. The process that follows is typically trying to resolve multiple issues: What happened, why, and who is ultimately responsible? To answer these issues, it is imperative to identify the “root cause” of the incident, or why it occurred in the first place. A problem-solving method called Root Cause Analysis (RCA) can be used to determine the exact origin of a problem. Signa uses a step-by-step approach to find the individual cause-and-effect sequence of events leading up to an incident. We regularly use RCA as a framework to assist attorneys in questioning witnesses and analyzing witness depositions. Frequently, there is a great deal of information that must be organized and cross-referenced. Signa uses the RCA event sequence as a basis for comparing individual witness statements. This helps to resolve conflicts by demonstrating which statements are supported by a preponderance of evidence. The final result is a highly-defensible engineering opinion, supported by both technical analysis and eyewitness accounts.
