The point map depicts hydrocarbon wells in the Federal Republic of Germany for which gas geochemical data (gas composition and stable carbon and hydrogen isotopic composition of gaseous hydrocarbons) are available at the Federal Institute for Geosciences and Natural Resources (BGR). It shows the locations the well name and the NIBIS well identifier (NIBIS map server of the State Office for Mining and Geology of Lower Saxony, as of 2019). However, due to legislative changes, wells in the EEZ as well as outside Lower Saxony are no longer present in the current LBEG map data. The wells shown with associated gas and/or isotope geochemical data were compiled from different internal data sources. However, due to this inhomogeneity, the amount of analytical data available, as well as additional sample data, varies widely. The data are only available after legal clarification with the well owner.
