Abstract

Oil India Limited recently conducted 3D seismic survey in transition zone of Krishna-Godavari basin (Dynamite+Airgun) within the block KG-ONN-2004/1 consists of different logistics such as human habitat, oil & gas pipe lines, fish ponds, prawn ponds, Tributaries of Godavari (Goutami Godavari) and paddy fields, coconut gardens, mangroves and coastal belt. Seismic data acquisition in different kinds of logistics needs various kinds of planning & implementation to achieve quality data and as well as time management for cost effectiveness. Often the data quality is controlled by the terrain logistics within the operational area where as the inaccessibility due to difficult logistics necessitated displacement of the source and receivers from their original position which in turn leading to either uneven sampling or data gaps in seismic imaging.
