Parameters description

The BKRIG algorithm is activated from Estimation | bkrig in the algorithm panel. The main BKRIG interface contains three pages: “General”, “Data” and “Variogram” (see Fig. 7.10). The text inside “[ ]” is the corresponding keyword in the BKRIG parameter file.

1. Grid Name [Grid_Name] Name of the estimation grid.

2. Property Name Prefix [Property_Name] Prefix for the estimation output.

3. Kriging Type [Kriging_Type] Select the type of Kriging system to be solved at each node: Simple Kriging (SK) or Ordinary Kriging (OK).

4. SK mean [SK_mean] Mean of the attribute. Only required if Kriging_Type

[Kriging_Type] is set to Simple Kriging (SK).

5. Block Covariance Computation Approach [Block_Cov_Approach] Select the method of computing block covariance: FFT with Covariance-Table or Integration with Covariance-Table.

6. Check block data reproduction [Check_Block_Reproduction] If checked, the estimated block average values are calculated and the relative errors compared to the input block data are computed for each realization. The results are shown on the Commands Panel, which is activated from View → Commands Panel.
