3d Contouring Hints
• Can “slice” into
contour shells by
modifying grid extent
• Inverse distance
seems to create

Volume / Mass Calculation
• EI Evaluates volume
within each contour

• Monte Carlo integration

• Mass = C x V x p...
Draped Image
• Image draped to
either:

 Ground Surface
defined at wells
 Set of X,Y,Z points
(DEM data)
