In these cases, tolerance parameters are required to infer an experimental variogram that is both precise and stable for subsequent modeling. This lesson focuses on variogram calculation in practical cases where the variogram must be inferred from limited, irregularly spaced measurements. The definition and calculation of the variogram is covered in any standard geostatistical text (Chilès & Delfiner, 2009 Pyrcz & Deutsch, 2014).
Kriging, Gaussian simulation, and indicator methods all require a variogram model for each variable in each domain. The variogram is a central parameter for many geostatistical techniques.
Check an experimental variogram for conformance to geologic interpretation and suitability for modeling. Specify reasonable experimental variogram tolerance parameters including lag distances and tolerances, angles, and bandwidths. Explain the definition of key tolerance parameters required for 3D experimental variogram calculation in irregularly sampled data sets.
