Description

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. Alberta Geological Survey Bulletin 66 provides a detailed description of how the unit was defined. The dataset is in ESRI ASCII grid format.

Description

This dataset evaluates the sandstone-hosted uranium potential of Alberta. An Alberta Geological Survey database of oil and gas well logs were queried to identify wells with gamma values greater than 300 API (American Petroleum Institute units). An algorithm written for this analysis queried more than 48 000 gamma ray logs from more than 22 000 wells. Of those, 11 476 readings greater than 300 API, within the upper 500 metres, were found in 6176 wells. We selected 1318 wells, verified the anomaly and determined rock types using a combination of gamma, density and resistivity logs. This dataset is associated with Alberta Geological Survey Open File Report 2009-0012.
