Resolution of Internal Basalt Structures Offshore Sri Lanka

Offshore Sri Lanka, basaltic flows and other intrusive bodies (sills and dykes) hamper efforts to image deeper structures. In this study, we demonstrate the ability of hi-resolution hybrid gridded tomography to resolve the internal structure of an extensive basaltic flow, revealing intercalated sedimentary units within the basalt. These findings are supported by well log measurements which penetrate one of the flows.
