TGI Stratigraphic Map Series Data Files

Data files used to create the stratigraphic maps series are supplied for each horizon. The data file can be downloaded here, and contains the raster file in ArcInfo grid format, data point shapefiles, contour shapefiles (structure and/or isopach), and the formation edge shapefiles.

The specialized combinations of spatial interpolation and filtering were chosen to portray the regional trends of the data at a small scale. As such, some of the data points may not match the contour values accurately in places, and it would be difficult to replicate the maps using the TGI database without the actual modelling script that was developed specifically for this project. Use of the data files supplied for each horizon is at the user discretion.

Materials may be available in alternate formats upon request.

Geophysical Investigations

This final geophysical report consists of regional gravity and high-resolution aeromagnetic maps that were compiled for the Williston Basin within the TGI study area, resulting in a seamless tectonic framework of the Precambrian basement rocks buried beneath the Phanerozoic sediments.

Map list

The links provide below give the corresponding maps in PDF format suitable for viewing and printing page-size as well as in about 1m by 1m images. The image file names begin with the map numbers followed by self-descriptive abbreviated captions. Note that several images have multiple versions (typically, contoured or non-contoured maps), indicated by letters appended to the figure numbers.

Field Trip Gas Well Demonstration

The gas well, shown in the videos, is situated on the north flank of the Pembina Hills, 6 km north-northeast of Notre Dame de Lourdes, MB, on the farm of Norman and Guy Bosc. In the 1930s, the well was drilled to a depth of about 52 m into the Cretaceous Favel Formation (Second White Specks), which is known to contain oil shale. The well produces natural gas, with a weak petroleum smell, that burns when ignited. The gas pressure drops to 3 lbs after being opened for ½ hour. When the valve is closed, the well recharges with 32 lbs gas pressure every 12 hours. Poor quality drinking water has been encountered in all nearby water wells.
