Abstract

Within the framework of theAppalachian Energy project of the TargetGeosciences Initiative - Part 2, more than 3000 km of single-channel, high-resolution seismic profiles were collected with a sparker source in the St. Lawrence estuary in 2003 and 2004 to map shallow sedimentary series (sediments and the top of the underlying bedrock). The data collected include many artifacts such as short- and long-period multiples. In order to provide, as much as possible, artifact-free sections, a processing flow was developed and applied to all 55 profiles collected. The core of the ten-step flow is a trace-by-trace deconvolution algorithm which allows the compression of the source signature. The processed sections provide improved seismic images that allow accurate picking of key stratigraphic reflectors.
