Petroleum geology - Natural Gas origin and Seepage

Hydrocarbons produced in the Earth’s crust represent the main energy source for the mankind and play important roles in many geological, environmental and climate processes.

Natural gas is mainly formed by methane (CH4) whose natural emission on the Earth’s surface is a significant greenhouse-gas source and potential hazard for local communities.

INGV Roma 2 research is focused on “seepage” phenomena, i.e. natural manifestations of gas and oil on the Earth’s surface. Studies include: origin of gaseous hydrocarbons, gas migration, chemical reactions in the lithosphere, emission into the atmosphere e related impact in the environment, climate and global changes.

The studies, performed so far in collaboration with international experts, resulted in a wide set of innovative results and publications.

European and global estimates of methane emissions from geologic sources
(acknowledged by the IPCC, the European Environmental Agency -EMEP/CORINAIR inventory- and the US Environmental Protection Agency – EPA).

Global data and statistics on methane origin from seep.

Global data-set of onshore seeps.

Development of innovative techniques for the measurement of methane flux from soil.
