Volumetric estimation. Volumetric estimates of OOIP original oil in place and OGIP original gas in place are based on a geological model that geometrically describes the volume of hydrocarbons in the reservoir. However, due mainly to gas evolving from the oil as pressure and temperature are decreased, oil at the surface occupies less space than it does in the subsurface.

Mineral resource estimation Wikipedia
Resource estimation is used to determine and define the ore tonnage and grade of a geological deposit, from the developed block model. There are different estimation methods (see below) used for different scenarios dependent upon the ore boundaries, geological deposit geometry, grade variability and the amount of time and money available.
Creating a Block Model in Maptek Vulcan Mining University
Contrary to popular belief, creating a block model in the Maptek Vulcan software package is not overly difficult. Estimating grades for the block model can be as tedious and convoluted as you want it to be but creating the shell for that model to go in is an elementary exercise.
