7 Burning Questions About Gas Migration

The carbon isotope signature of methane is often presented as the ‘silver bullet’ capable of identifying whether soil gas is from a deeper thermogenic source or produced by microbial processes. The stakes are high because failing to identify a gas migration (GM) issue can have serious environmental consequences…

Methane is from a Deeper Thermogenic Source . . . Or, is it?

The carbon isotope signature of methane is often presented as the ‘silver bullet’ capable of identifying whether soil gas is from a deeper thermogenic source or produced by microbial processes. The stakes are high because failing to identify a gas migration (GM) issue can have serious environmental consequences…

Why ethane is a key indicator to identify gas migration

Ethane is a reliable geochemical tracer that can be used as a single line of evidence to identify a potential gas migration issue. Ethane and longer chain hydrocarbons are produced during the thermal degradation of organic matter (kerogen) over geological timescales. Microbial …
