Abstract
Summary
Detection and characterisation of shallow gas in the marine environment is a principle reason for carrying out geohazard site surveys prior to commencing rig installation and drilling operations (OGP, 2011). In order to achieve this, 2D or 3D high-resolution multichannel seismic data, or a combination thereof, is acquired throughout the area of interest and subsequently interpreted using a combination of manual and automatic techniques.
