Almost all of the isotope data in the U of A archive of SCVF and GM have been cleaned and most of that data has been mapped on both province wide and regional scales. Regional isotopic variations can be identified on the maps which suggests the source depths of problem, stray gases
at oil and gas wells, may be regionally controlled. An important new finding is that SCVF in a given cluster of wells originate at the same source depth but adjacent clusters of wells can have dramatically different source depths of SCVF.
Production data has been cleaned but still needs filtering. We have started work on production gases in the Montney where large regional variations of carbon isotope values are apparent.
