Distribution of Total Dissolved Solids in the Spirit River Hydrostratigraphic Unit (gridded data, ASCII format)

This grid represents the distribution of total dissolved solids (TDS) in the Spirit River hydrostratigraphic unit (HSU). It is a result of a geostatistical model which was constructed using publicly available formation water chemistry data from drillstem tests and production fluids from oil and gas wells.

The TDS distribution was mapped at a regional scale using many years of data, thus providing a good indication of regional water chemistry within the unit rather than site-specific values.
