Abstract

The villages, industrial campus, water logged areas are the common obstacles encountered almost everywhere in land acquisition works. Presence of such obstacles in land seismic surveys are characterized by NSO (Non Seismic Objects) and create difficulties in placing source and receivers along the desired location which ultimately leads to loss in foldage and source-receiver offsets and azimuths. However, these losses can be minimized up to some extent by modifying the layout for missing shots and receivers within certain limits. The most common NSO types i.e. water logged and populated regions were encounter in the present 3D block. An effective approach to negotiate with fold, associated offsets, and azimuth is explored and discussed.
