Inorganic Elemental Data 101: Evaluating Redox Conditions in Mudstones

This webinar was given on April 14, 2020 as part of Chemostrat Inc's April webinar series. The webinar discusses the merits of incorporating elemental data into the analysis of unconventional reservoirs, and provides an overview of common methods for determining degree of basin water restriction and oxygen depletion.
