Preliminary FWI results from Snowflake II

Scott Keating, Kristopher A. Innanen

In 2022 a vertical seismic profile survey was shot at the Carbon Management Canada Newell County Facility as a follow-up to a 2018 survey, after years of CO₂ injection at the site. We perform preliminary processing and inversion of the new data, using the inversion approaches and parameters used on the 2018 data set. Probable errors in the inversion output motivate a strong possibility that several of the inversion parameters may need to be modified to achieve a comparable result with the 2022 data set.
