MudRisk- a new tool for the detection of fluid pathways around mud volcanoes in Azerbaijan

Merz, Lena; Huseynova, Ayten; Babayev, Elbay; Hilgers, Christoph

Abstract (englisch):

Mud volcanoes are abundant geological phenomena in the southern Caspian Basin related to very high subsidence and sedimentation rates. In Azerbaijan more than 200 mud volcanoes were mapped onshore. In the surrounding of the mud volcanoes ascending hydrocarbon rich fluids and gases affect groundwater and soil quality. Hydrocarbon systems are closely related to mud volcano fluid systems and fluids mainly consist of methane. The aim of our project is to map micro-seepage and draw conclusions about migration pathways of gas in the wider area of mud volcanism, as well as to evaluate the environmental influence of these seepages. Therefore, we couple Structure from Motion with methane measurements and soil and groundwater analysis and integrate all the data in a subsurface model.

We couple a hexacopter with a methane gas sniffer based on laser detection and map the area around mud volcanoes, where micro-seepage occurs along fractures often related to regional anticline systems. In a first field campaign we test this innovative method on selected mud volcanoes from different regions in Azerbaijan. Simultaneously we conduct photogrammetry of the area around mud volcanoes to image fracture systems and support the results from methane measurements. ... mehr
