Advanced and Specialty Classes

Earth Volumetric Studio is a comprehensive toolkit.  Our  Advanced and Specialty class series is designed to introduce our experienced users to some of the more powerful features of the software to unlock new capabilities as well as enhance your standard modeling procedures.   These classes are recommended for experienced users as well as those with only a few months working with our software.  Completion of the Introductory Class series or equivalent is required.  Some classes have additional prerequisites as stated.

Advanced Variography in krig_3d: 4 Hours: $450 per person

Learn how to take advantage of krig_3d’s ability to create and use fully 3D anisotropic variograms. This class will be taught from an environmental engineer or geochemists perspective rather than a geostatistician’s. We will focus on how to recognize the need for complex anisotropic variography based on project knowledge as well as trends in the data. We will then show how to use graphical techniques to determine the variogram ellipsoid heading and dip as well as primary and secondary anisotropies.

This is not a geostatistics class and has no geostatistics knowledge prerequisites, nor is it intended to make you an expert in variography or geostatistics. Individuals with a background in geostatistics will likely benefit from the mechanics being taught in this class, but may find the approaches presented unconventional.

NOTE: The Python Scripting Class is highly recommended but not a formal prerequisite for this class.

  • Ellipsoid as a variogram surrogate
  • Understanding heading and dip
  • primary and secondary anisotropy
  • Z Scale issues
  • Optimization
  • variogram models
