Description:
Abstract:

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.

Purpose: For computer display, query and modelling of the hydraulic head surface for the Wabamun HSU.
