The GARAH project main result was a harmonized, scientific based, geological analysis and assessment of the conventional and unconventional hydrocarbon resources that will help member states to continue the transition to lower Carbon energy sources. The assessment contributed to climate commitments and allows the planning for secure sources of affordable energy. The analysis and assessment of hydrocarbons was focused on two areas:

(i) in Europe’s major petroleum province – the North Sea a “Geological analysis and resource assessment of North Sea petroleum systems”. This research included the assessment of conventional and unconventional oil and gas resources in the most important hydrocarbon basin in Europe. This enabled the remaining resource to be better understood and managed and identified options for multiple and alternative uses of the subsurface as producing fields come off-line.

(ii) with a pan-European view, “Addressing knowledge gaps in the hydrate assessment in the European continental”. This research included an assessment of the knowledge gaps of marine gas hydrate related information and subsequently, presented the current state of hydrate-related pan-European data. In addition, this research showed an assessment of marine gas hydrate-related geohazards (susceptibility map) and areas of interest for future scientific projects related to the potential safe geological storage of CO2 as mixed gas hydrates.
