Analysis of spatial and temporal heterogeneities of methane emissions of reservoirs by correlating hydro-acoustic with sediment parameters

The quantification of methane emissions from reservoirs is still imprecise. This study aims on the improvement of methods to understand the relevant processes causing heterogeneities. By conducting hydro-acoustic surveys, morphometric information was obtained. Seabed classification was conducted, including extensive ground truthing, which allowed spatial interpolation. It was possible to link the sediment distribution to quality parameters and to characteristics determining methane production.
