Following Cedar Hanneson, Rob Vestrum took the stage to share his experiences and learnings. His talk highlighted historical and modern advancements in seismic imaging across complex geological structures from the Rockies to the Andes. He traced the lineage of innovations from the early 20th century to contemporary applications, illustrating how each technological leap was necessitated by the challenges posed by increasingly complex subsurface environments.

The morning session wrapped up with an engaging Q&A, sparking a lively debate on the future of geothermal energy in Canada, demonstrating the Symposium’s role as a starter for robust scientific exchange. Discussions on the future of geothermal energy in Canada were marked by diverse opinions, showcasing a vibrant community engaged in shaping the future of geophysical exploration. The level of professionalism and respect in the discussion was exemplary, showing how scientific debates should be conducted—focused on data and facts, rather than personal biases.

Rachel Newrick’s talk, “Into the Mind of a Seismic Interpreter”, provided a deep dive into the complexities of subsurface analysis, crucial for petroleum exploration. Her presentation went beyond technical explanations, to question the very basis of seismic interpretation practices. She challenged attendees to think critically about data analysis and decision-making processes in geophysical studies. Her reflective questions and methodical approach to seismic interpretation emphasized the importance of a thorough analytical and creative process in geophysical exploration.

Marcia Couëslan’s presentation, delivered by Richard Gray, on the role of geophysics in reducing risk and uncertainty in carbon capture and storage (CCS) projects, highlighted the importance of various geophysical tools in reducing project uncertainties before, during, and after the operational life of these projects. Additionally, the talk discussed alternative monitoring technologies such as time-lapse vertical seismic profile (VSP) surveys and surface-based distributed acoustic sensor (DAS) installations, to optimize monitoring of CO2 plumes. The presentation also addressed the potential for induced seismicity, emphasizing the development of effective monitoring strategies to ensure safe operations and enhance public and regulatory trust in CCS projects.

The afternoon began with Rob Stewart sharing personal anecdotes and experiences with Don Lawton, complemented by captivating videos of their field adventures together. This session not only highlighted the technical expertise of the speaker, but also his personal journeys and the impact of Don Lawton to his work on the global stage.

Humaira Ghiacy, from Deloitte Global, then delivered the Luncheon Keynote Speaker’s talk on “Embracing the Hybrid Work Model”, discussing the challenges and opportunities presented by the evolving global work environment. This talk was particularly relevant, offering insights into the future of work in a post-pandemic world.

Key Takeaways from the Second Half

The final sessions of the Symposium introduced cutting-edge technologies and methodologies. Mostafa Naghizadeh discussed, “Miniaturized Seismic Sources and Dispersed Source Arrays”, showcasing efforts to minimize the environmental impact of seismic surveying. His detailed description of the field tests conducted, and the comparative analysis of miniature versus conventional seismic sources, provided a concrete example of how geophysical practices are evolving in response to environmental concerns. The miniature sources achieved comparable resolution to conventional sources across all targeted depths, highlighting the potential to reduce the environmental footprint of seismic activities.

Next, followed a presentation by Kimberly Pike from CREWES, who highlighted the pivotal role of seismic technologies in supporting CCS through measurement, monitoring, and verification. CREWES is exploring various adaptations of traditional seismic methods to offer cost-effective and reliable monitoring solutions that also provide robust estimates of uncertainty. In collaboration with Carbon Management Canada, CREWES conducted multicomponent surface and VSP surveys at the Newell County CCS site in southern Alberta, during CO2 injection. These surveys utilized a mix of geophones, accelerometers, and both single- and multi-component DAS technologies. The data collected from these tools were used to evaluate different sensors, and test full waveform inversion (FWI) methods specifically tailored for CCS applications. The presentation showcased field data, FWI results in 2D and 3D, error estimations, and preliminary conclusions from the tests conducted at this well-documented site.

The final session of the day started with Ashlee Fudge’s talk, “A Towed Marine Time-Domain Electromagnetic Method for Evaluating the Continuity of an Aquitard”. She discussed the use of time domain electromagnetic (TEM) methods, specifically through Geonics Ltd.’s G-TEM system in a mobile, waterborne setup, for investigating hydrogeological properties beneath a lake. The primary aim was to map the continuity and composition of a conductive glacial clay till unit that lies beneath the surface water body. The G-TEM system enabled rapid and high-resolution data acquisition across the lake, aiding in hydrostratigraphic mapping and evaluation of the clay till aquitard. Preliminary results indicated variations in the depth of the clay till, suggesting possible hydrogeological pathways between deep underground structures and the glacial till. These findings were consistent with previous ground TEM surveys and borehole data, and will be used to identify strategic drilling locations, to further understand hydrogeological processes affecting the lake. This talk was interesting and showed amazing pictures of field campaigns in the middle of the lake. It was also encouraging to see people involved in other topics, apart from seismic exploration.

The Symposium concluded with Jason Schweigert’s presentation on “Theseus 24D: From Pilot to Commercial CCS MMV Programs,” which proposed a streamlined approach to seismic monitoring in CCS. This final talk tied back to the Symposium’s theme of practical applications in geophysics, paying homage to Don Lawton’s contributions to CCS projects. Furthermore, Jason presented an introduction to Theseus 24D, which integrates repeated 2D and 3D surveys to minimize the need for 3D surveys.

The day ended with an Industry Mixer. This is generally my favourite part of this type of event, as it provides me with opportunities to reflect on the day’s learnings, build a network, and make friends in Calgary while discussing interesting topics.
