An isopach map illustrates the thickness variations within a subsurface unit, layer, or stratum. Download the data and follow along as we showcase the best workflow for creating isopach maps in Surfer to identify assets in the field, calculate area, determine the volume of the isopach, and analyze the data through reporting.
Golden Software’s training coordinator, Drew Dudley, focuses on specific examples using the most current version of Surfer, although the principles we'll be reviewing can be applied to almost any subsurface data set.
Specifically, the presentation covers the following topics:
- Use Surfer’s Grid Math tool to create isopach maps
- Visualize the isopach maps using contour layers and 3D surfaces
- Use Surfer’s Grid Volume tool to calculate area and volume between surfaces
- Extract volumetrics from within a specific boundary
