What is NOT a method for obtaining 2D volumes before constructing a detailed 3D model?

A method for obtaining 2D volumes before constructing a detailed 3D model that is NOT mentioned in the text.

What type of maps are used as input for obtaining 2D volumes?

Maps that illustrate geological structures and formations.

What caution should be exercised when presenting pore-volume/HCPV/STOOIP/GIIP numbers based on 2D volumes?

2D volumes are averages and don't reflect individual rock properties.

Which panel in the software displays the values for cut and fill volume?

A panel within the software that clearly presents the difference in volumes between the original and final surfaces.
