Presenter: Megan Boutin, Suncor Energy
A Comprehensive Approach to Caprock Characterization, Suncor MacKay River Asset
Chairs: Sajjad Ansari, Schlumberger; Majid Saeedi, PennWest Exploration
This session will address the engineering challenges associated with understanding caprock integrity. For example, calculating caprock minimum stress is one of the main factors in determining the maximum operating pressure (MOP) and there are a numerous methods that could lead to different estimates. Furthermore, rock mechanical properties obtained from lab core testing have inherent uncertainties and these datasets are used in the building of geomechanical models. This session will be focused on addressing some of these challenges.
Presenter: Rick Chalaturnyk, University of Alberta
Causes of and Solutions to Uncertainty in Lab Based Geomechanical Properties
Presenter: Michael O'Hara, Devon Energy
Cap Rock Integrity Testing at Pike—Does Pumping Volume Matter?
Presenter: Lennert D. den Boer, Schlumberger & Dale Walters, Taurus Reservoir Solutions Ltd.
Techniques for Modelling and Evaluating Caprock Integrity
Chairs: Tim O’Connor, MEG Energy; Dan Lowe, Canadian Natural Resources Limited
This session will highlight the role that caprock integrity plays in subsurface design. A schemes' subsurface design must include provisions to maintain and monitor caprock integrity across the full asset lifecyle from well placement to abandonment. This can be accomplished with appropriate material selection, installation methods (drilling, cementing and completions), well types and configurations, and instrumentation technologies. Examples and challenges will be discussed.
Presenter: Jennifer Sawatzky, Canadian Natural Resources Limited; Martin Côté, CanmetMINES

Realizing the Full Potential of Multi-Finger Caliper Logging for Caprock and Casing Integrity Monitoring
Chairs: Ken Mislan, Husky Energy; Michelle de Jeu, Devon Energy
This session will highlight the role that caprock integrity plays in surface design. A schemes’ surface design must include provisions to maintain and monitor caprock integrity across the full asset lifecycle from first steam to facility abandonment. An overview of surface design best practices, including risk based evaluation tools, will be discussed.
Presenter: David Burdziuk and Jan Rasmussen, Suncor Energy
SAGD Sub-Surface Event Tree Risk Analysis and Its Influence on Facility Designs

Are Your Alarms Working for You or Against You—Alarm Management in Thermal Operations
Chairs: Tim O'Connor, MEG Energy; Kim Chiu, Southern Pacific Resource Corp.
This session will address how the operating strategy must be considered as an integral component in caprock integrity management. It is the injection operations of in-situ processes that creates the need to have measures and procedures in place to maintain the hydraulic isolation. This session will cover topics including different operating strategies, MOP management, and alarm systems and procedures.
Presenter: Craig Davidson, Suncor Energy
Considerations in Creating an MOP Operating Strategy
Presenter: Joe Kuhach, Ivanhoe Energy
Operating Strategy to Minimize Risk in a Shallow SAGD Development at Tamarack
Presenter: Hanh Nguyen, Marathon Oil Corporation
Geomechanics Program at Marathon Oil Birchwood Project
Chairs: Dustin Bespalko, Imperial Oil; Jin Wang, Suncor Energy
This session will address how a robust monitoring strategy must be considered as part of caprock integrity management. How can various monitoring technologies be combined, deployed, and maintained in thermal operations? Which of those are real time proactive systems? What technologies should be retired, and what is industry targeting for innovation?
Presenter: John Kwong, Imperial Oil
Cold Lake Grand Rapids Pressure Monitoring
Presenter: Kevin Ma, Statoil; Alexandra Robertson, Statoil
Integrated Reservoir Monitoring at Statoil Leismer Demonstration Project: Case Evaluation and Operational Application
Presenter: Bob Whale, Shell Canada
Update on Reservoir and Caprock Monitoring at Shell’s Orion and Peace River Thermal Projects
Chairs: Dale Walters, Taurus Reservoir Solutions Ltd.; Pingke Li, Sunshine Oilsands
Experience is as important for knowledge as education. The field experiences shared in this session present what can go wrong, how risks associated with caprock can be mitigated, and how monitoring and response techniques can be used to respond to and manage events and their consequences.
Presenter: Dan Lowe, Canadian Natural Resources Limited
