Description:
Abstract:

This grid represents the distribution of hydraulic head in the Keg River / Winnipegosis hydrostratigraphic unit (HSU). It is a result of a geostatistical model which was constructed using publicly available pressure data from drillstem tests from oil and gas wells as well as industry monitoring wells accessed through environmental impact assessment reports.

The hydraulic head surface was mapped at a regional scale using many years of data, thus providing a good indication of regional groundwater flow within the unit rather than site-specific values.

Purpose: To provide the regional hydraulic head surface for the Keg River / Winnipegosis HSU

Data Quality Information:
Attribute Accuracy:
Attribute Accuracy Report:

The following statistics describe the accuracy of the geostatistical layer used to create the final grid.

Mean error: -1.3 m

Root mean square error: 54 m

Mean standardized error: -0.006

Root mean square standardized: 1.1

Average standard error: 49 m

Logical Consistency Report:
Grid cell spacing is 1000 metres by 1000 metres. Grid cells with no data are assigned the value -9999.
Completeness Report:
The final hydraulic head surface map covers the extent of the Keg River/ Winnipegosis HSU as modelled in the 3D Provincial Geological Framework Model of Alberta, version 3. In addition, the final map was clipped to the spatial extent of data.

Process Step:
Process Description:

Step 1 (Modelling the surface): A simple kriging algorithm was used in the ArcMap Geostatistical Analyst extension to interpolate the hydraulic head values and create a grid of the head surface of the Keg River / Winnipegosis HSU.

Method Report:

Output surface type: Prediction

Variable: Semivariogram

Type: Spherical

Neighbourhood type: standard

Samples: 309

Cell size: 1000 m

Step 2 : The final grid was clipped based on the extent of the Keg River / Winnipegosis HSU, and spatial distribution of data.
