This grid represents the distribution of hydraulic head in the Wabamun hydrostratigraphic unit (HSU). The distribution of hydraulic head is a result of a geostatistical model which was constructed using publicly available pressure data from oil and gas well drillstem tests (DSTs).
The hydraulic head surface was mapped at a regional scale using many years of data, thus providing a good indication of hydraulic head within the unit rather than site-specific values.
The following statistics describes the accuracy for the final HH grid:
Prediction Errors
Samples: 533
Mean: -0.00723
Root-Mean-Square Error: 39.8102
Root-Mean-Square Standardized: 1.002092
Average Standard Error: 36.78406 masl
