Session 2: Risk Management Tools for Abandonments, Surface Casing Vent Flow and Well Integrity Issues
Session Chairpersons Leah Davies, Manaka Consulting Ltd.; Manuel Oppel, Aurora Land Consulting Ltd.
Speaker(s) Todd Zahacy, C-FER Technologies and Barkim Demirdal, Devon Canada; Anthony Knafla, Equilibrium Environmental Inc.; Bryce Levett, DNV GL

In this session you will learn about tools, statistical analysis, and modeling techniques to organize your abandonment program based on risk in order to maximize liability reduction. Understating historical well failures can help predict project risks based on location, geology, age, technology deployed, and practices by providing estimates of expected failures, required workover frequency, maintenance, repair and decommissioning costs. Knowing which wells might pose the greatest risk and why is beneficial to operators, technology providers and regulators.

In this session, presentations will discuss the work and research that is currently being done to better understand the impacts of surface casing vent flows and gas migration. The intent of the research is to find alternatives to move away from the current pass/fail criteria towards a threshold based criteria at time of cut and cap.

Area-Based Closure (ABC) is a new industry wide initiative designed to lower closure costs through improved regulatory effectiveness and increased operational efficiency. 

This session explores recent Area-Based Closure (ABC) pilot program results from two industry operators including the operational efficiencies achieved from an ABC approach, as well as the learnings they gained. This session also evaluates the importance and impact that data can have on ABC program decision making and how non-conventional decommissioning of low risk wells can save money without sacrificing environmental outcomes.
