Description:
Abstract:
This grid represents the distribution of total dissolved solids (TDS) in the Wabamun hydrostratigraphic unit (HSU). It is a result of a geostatistical model which was constructed using publicly available formation water chemistry analysis data from oil and gas well drillstem tests and production fluid samples. 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.
Purpose: For computer display, query and modelling of TDS data for the Wabamun HSU.
