Description

This digital dataset represents the modelled outputs of the three-dimensional distribution of sandiness in the Paskapoo Formation, Alberta, Canada. Sand-abundance values were determined from log analysis of water-well lithologs and petroleum exploration downhole-geophysical logs, specifically gamma-ray logs. We derived the sandiness values by calculating the average sandiness in 25 m thick slices above the base of the Paskapoo Formation in a borehole and by assigning the average value (P50) to the midpoint of each slice interval. Alberta Geological Survey Bulletin 66 provides detailed descriptions of the methodology. We tested the borehole sand-abundance values in a 3-D variogram prior to kriging in a regular block model consisting of cells with dimensions of 1000 m on the x and y planes and 25 m in the z (elevation) direction. Values of modelled sandiness range from 0 (absence of sand) to 1 (100% sand) and are assigned elevations based on two datums: 1) a stratigraphic level...

Description

Since its inception in 1920, the Alberta Geological Survey (AGS) has drilled several thousand boreholes across the province. Most were drilled only into the unconsolidated sediments overlying the top of bedrock. In 2010, AGS staff began a project to systematically compile all of the borehole log information into a database. This Digital Data product and its companion Open File Report, OFR 2014-06 are the interim results of this initiative. The dataset comprises three tables: Sources.txt, Boreholes.txt and Intervals.txt, as well as metadata. The Sources table gives summary information about the AGS project for which each borehole was drilled. The Boreholes table gives summary information about each borehole, such as location, drilling method, date, and total depth of the hole. The Intervals table gives descriptive geological information about each distinct geological horizon encountered in the borehole, including lithology and colour of the material. The tables have primary keys on...

This dataset is part of the three-dimensional (3-D) hydrostratigraphic model of the Sylvan Lake sub-basin in the Edmonton-Calgary Corridor, central Alberta. It represents the structure top of hydrostratigraphic unit (HSU) S2, which contains coarse-grained material found in upland areas and discontinuously overlies buried valleys, as intradrift sand or terraces adjacent to and underlying present-day streams, rivers, and lakes in the Neogene-Quaternary succession of the Sylvan Lake sub-basin. This dataset supplements Alberta Geological Survey (AGS) Open File Report 2014-10, which includes a full description of steps taken to produce the structure grid.

Description

This grid dataset is part of the three-dimensional (3-D) hydrostratigraphic model of the Sylvan Lake sub-basin in the Edmonton-Calgary Corridor, central Alberta. It represents the structure top of the Paskapoo Formation, which is the bedrock surface in the Sylvan Lake sub-basin. The Paskapoo Formation is a highly heterogeneous system. To satisfy the needs of a groundwater flow model, internal characterization of rock properties was necessary to partition the formation into three distinct geological domains. The Upper Composite Slice is the uppermost of these three domains. Alberta Geological Survey (AGS) Open File Report 2014-10 includes a full description of the process used to produce this structure grid.

It represents the net-to-gross sandstone ratio distribution within the Paskapoo Formation - Upper Composite Slice of the Sylvan Lake sub-basin. The Upper Composite Slice is one of three distinct geological domains identified in the Paskapoo Formation of the Sylvan Lake sub-basin model. Characterization of net-to-gross sandstone ratio distribution within the Paskapoo Formation provides information about the geological heterogeneity and potential hydraulic connectivity within the formation for input into a groundwater flow model.
