St Walburg Isopach: Stratigraphic Framework Maps for Saskatchewan

Stratigraphic framework maps for the Saskatchewan Phanerozoic Fluids and Petroleum Systems project were produced using a 2 km equi-spaced modified grid generated by Golden Software’s Surfer 9 kriging algorithm. The Government of Saskatchewan compiled and validated data from multiple regional projects completed between 2003 and 2009, incorporating well data from adjacent jurisdictions to minimize edge effects during contouring. This dataset includes structure, isopach, and zero edge files available in multiple geospatial formats.

Use Cases

• Model petroleum system evolution based on stratigraphic framework maps.
• Analyze subsurface structure and thickness variations using isopach maps.
• Correlate regional geological formations using validated well data from multiple projects.

Strengths

• Data was validated and edited to facilitate correlations between multiple regional projects.
• Incorporates stratigraphic data from wells in adjacent jurisdictions to minimize edge effects.
• Produced using a standardized 2 km equi-spaced grid and kriging algorithm for consistency.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the source projects.
