Seismic Imaging Technology Part II

Seismic imaging is considered key to reducing risk and cost in exploratory as well as development drilling. Seismic acquisition geometry impacts the seismic image, so in this article we show how advances in imaging deepwater subsalt plays in the deep water Gulf of Mexico is a result of the way the industry has embraced the wide azimuth streamer survey technique.

Ocean bottom seismic (OBS) produces superior seismic images compared to those from conventional 3D streamer seismic. OBS acquisition offers the prospect of full illumination and high multiplicity of signals from the same subsurface points (high data fold).
