Liability Challenges in Alberta
Rob Wadsworth, VP of Closure and Liability
Alberta Energy Regulator (AER)
This session will provide an overview of current and past research projects conducted by the Regulators related to abandonment requirements, leakage from abandoned wells and factors influencing wellbore leakage.
- Safe, Permanent Closure of the Medicine Hat – Alderson Commingled Gas Fields, Southeastern Alberta Management Unit
- Dan Palombi, Alberta Energy Regulator (AER)
- Assessing Well Construction and Decommissioning Practices by Testing for Wellbore Leakage – 2018 Results
- Kevin Parsonage, BC Oil & Gas Commission
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.
- Risk-Ranking Approach for Thermal Well Integrity Using Readily Available Application, Well and Operational Parameters
- Todd Zahacy, C-FER Technologies
- SCVF & GM Risk Ranking and Prioritization Tool
- Anthony Knafla, Equilibrium Environmental Inc.
- Tools for Risk-Based Well Abandonment Design and Implementation
- Bryce Levett, DNV GL
One of the recently sanction Industry Recommended Practices (IRP), IRP 26: Wellbore Remediation, will be introduced and the scope of work discussed. This discussion will then continue with a breakout session on Day 2 of the workshop.
This session will present three newer technologies that offer alternatives to the traditional cement squeeze practice. New materials and methodology will highlight the session.
- TBC, Univiersity of Texas
- Permanent Abandonment of Wells
- Michael Skjold, Interwell
Accurate identification of the gas source and any associated wellbore problems are important tools in any remedial operation when combating SCVF and well issues. In this session, methods and tools that can aid in the scoping out and remediation of SCV repairs will be discussed to help broaden the attendees' knowledge base.
- Steam Condensing Manifold (SCM) System for Collecting Representative Natural Gas and Condensed Steam Samples from Leaking Surface Casing Vent (SCV) of Thermal Wells
- Bryan Szatkowski, GCHEM Ltd.
- The Radial Cased Hole Analysis Tool
- Rose McPherson, GeoLog Solutions Inc.
Wednesday, September 19
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 a recent case study from CNRL highlighting some of the operational efficiencies that can be gained through area-focused closure programs, the importance and impact of quality data on ABC decision making, and how non-conventional decommissioning of low-risk wells can save money without sacrificing environmental outcomes.
- Examples of Area-Based Closure Successes, and the Opportunities for Efficiencies with High-Density Site Closure
- Ryan Munro, Canadian Natural Resources Limited. (CNRL)
- Data Management and its Impact on Area-Based Abandonment
- Martin Fleming, Dynamic Risk
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.
- Summary on Workshop Outcomes
- Marc Godin, Portfire Associates (PTAC)
- Gas Migration Study
- Brian Lemoine, ESSO (IMPERIAL)
- Aaron Cahill, University of British Columbia
This session addresses the challenges in plug and abandonment practices, defining available economic options to liquidate wells at the end of life cycle. By going beyond what has already been established within current practices and procedures in Canada, this session adds originality and innovation in different jurisdictions where new methods and technologies were successful in performing Plug and Abandonment operations at lower costs.
- SCVF and GM Remedial Elimination
- Jeff Saponja, Heal Systems
- Alternate Approach to P&A
- Ekene Ogbechie, Helix Energy Solutions Group
- Huldra Field, a Case Study in Alternative Approaches to P&A in Norway
- David Buchmiller, DNV GL USA, Inc.
During this break out session, teams will be given different wellbore remediation issues to work through and create a work flow document. These documents will then be used in the creation of IRP 26.
