Isotopic Signature of Nitrogen - An Indicator for Timing N2 Generation and N2 Charging of Dutch Natural Gas Accumulations

摘要

This paper provides data on the isotopic composition of nitrogen in natural gases of offshore and onshore Netherlands and proposes a process-based interpretation of the observed regional variation in isotopic characteristics. The nitrogen isotopic data clearly reveal a distinct regional distribution which - in combination with the regional differences in geological history - strongly suggests that differences in isotopic signature are related to regional differences
