Webinar Part 1: Overview of the New Guidelines
In Part 1 of this two-part webinar series, C-FER project lead Mark Stephens will provide an overview of the quantitative risk assessment (QRA) process that forms the basis for the guidelines, with a focus on the two key process elements: risk estimation and risk evaluation.
The discussion of risk estimation will include a review of analysis methods and modelling options for:
- Failure frequency estimation,
- Failure consequence estimation, and
- Risk estimation.
Webinar participants will learn how to develop frequency and consequence estimates that can be combined to provide meaningful measures of public safety and environmental risk during normal well operation and during well entry. They will also learn how best to combine the operational and entry risk measures for the purpose of risk evaluation.
The discussion of risk evaluation will focus on how to use the results of risk estimation to inform well design and integrity management using two distinct approaches:
- Risk evaluation based on defined acceptance criteria, and
- Risk evaluation in the absence of acceptance criteria.
Webinar participants will learn how to combine risk estimation results and acceptance criteria to make decisions when the necessary criteria do exist, and how to use the results of risk estimation to make decisions based on comparative scenario evaluation when criteria do not exist.
Part 2 of this webinar series will review the demonstration analyses that serve to Illustrate application of the QRA process. These analyses also formed the basis for the directional findings that are intended to support the development of best practices for different well completion types and well entry practices.
