A seismic survey that was acquired in September and October of 2024 at Carbon Management Canada’s Newell County Field Research Station, was repeated in March 2025 with the addition of source Line 7. Vibe Points (VP) were acquired using the University of Calgary’s IVI EnviroVibe, using a 16 second long 10-150 Hz linear sweep with 0.2 s start and end tapers. Lines 7, 13, 15, and 41 were shot with 4 sweeps per VP, and Lines 200 and 420 were shot with 20 sweeps per VP. A total of 310 VP were acquired over the course of the survey. Data were recorded on fiber in the observation wells and trench, the Pretzel and Croissant sensors, and surface geophones. We show a qualitative comparison of synthetic data for Croissant 1 created with ElasWave3D to field data for Croissant 1 and to field data recorded on geophones.
