Found 10 records similar to Isopach of the Sunchild Aquifer, Alberta (Gridded data, ASCII format)

Provincial

This is a 1000 m cell-sized raster dataset of the upper surface of the Sunchild Aquifer, modelled from the >55% sand point data derived by depth-slice analysis of well-log data. Alberta Geological Survey Bulletin 66 provides details on this grid dataset. The dataset is in ESRI ASCII grid format.

This dataset is a grid of the thickness of the Haynes aquifer within the Paskapoo Formation. The Haynes aquifer is a regionally extensive body of sand that lies in the bottom part of the Paskapoo Formation. The isopach was created from the modelled results of the average sandiness of 25 m thick slices in boreholes completed within the Paskapoo Formation. Parts of the aquifer are as much as 100 m thick, particularly in the west near the deformation belt and in a region west of the city of Red Deer.

This is a 1000 m cell-sized raster grid dataset of the top of the sandstone of the Haynes member of the Paskapoo Formation. We mapped the sandstone using 3-D geostatistical modelling algorithms from data derived from sand calculations of 25 m thick slice intervals of the Paskapoo Formation. We selected the >55% sand isovalue to define sandstone, based on the results of mini-models that show vertical hydraulic connections being established if sand abundance is 55% or greater. This grid represents the upper surface of that three-dimensional body defined by the >55% sand threshold value.

This dataset maps the thickness of the Lacombe aquitard as defined by outputs of a 3-D model of sandiness in the Paskapoo Formation. The Lacombe aquitard consists of >65% non-sandy material in stacked, 25 m thick slices above the base of the Paskapoo Formation.

This is a raster dataset of the thickness of the Paskapoo Formation. It is a derived dataset created by the subtraction of the base of the Paskapoo Formation from the top of the formation, which in the western part of Alberta is also the bedrock topography. The gridded isopach data cover only the undeformed part of the Paskapoo Formation that extends west to the front ranges of the Rocky Mountains. The isopach data do not include those parts of the formation affected by tectonic folding or thrusting.

The base of the Paskapoo Formation is unconformable with the underlying Scollard Formation. Alberta Geological Survey differentiates the Paskapoo Formation from the underlying Scollard Formation by the first thick sandstone above the uppermost coal seam of the Ardley coal zone. We defined 'thick sandstone' to be 5 m or more thick. This dataset contains the gridded results of the structural surface of the base of the Paskapoo Formation modelled from stratigraphic picks of the >5 m sand above the Scollard Formation coal from oil and gas industry gamma-ray logs.

This GIS dataset depicts a geostatistical model of the thickness of sediment overlying bedrock in Alberta. The sediment thickness surface was generated to assist the construction of a new geological framework for Alberta. The surface was derived by subtracting the bedrock topography of Alberta (Alberta Geological Survey Map 550) from the 60 m Shuttle Radar Topography Mission digital elevation model. These data comprise the raster surface of Alberta Geological Survey Map 551, Thickness of Quaternary and Neogene Sediment in Alberta, Canada.

This dataset represents the topography of the top of the Paskapoo Formation, which is also the bedrock topography in the western part of Alberta. We clipped the surface from Alberta Geological Survey's Bedrock Topography of Alberta grid using the areal extent of the Paskapoo Formation shown on Alberta Geological Survey Map 236, Geological Map of Alberta. The dataset is in ESRI ASCII grid format
