Shallow High Resolution Images from 3D Conventional 3D Seismic Data
Friday 15 June 2018
|Title:||Shallow High Resolution Images from 3D Seismic Data|
|Convenors:||J. Fasterling (Total)

In the distant past, near surface characterization and imaging has not been the focus in traditional seismic workflows. Due to cost saving efforts, complementing information to site surveys has been put more into focus and shallow exploration targets have created more attention on the quality of shallow imaging. In deep water environment, tailored processing has been successfully applied to conventional towed streamer to produce high resolution imaging of the seafloor and below and in many cases replaced the need for a site survey. The same could not be said for shallow water environments where the lack of near offset of towed streamer acquisition impaired on the ability to produce shallow high resolution imaging.
In this workshop we want to discuss how new methods in acquisition (configurations that optimize the near offset information, high resolution sources, …), processing (FWI, other inversion tools, new seismic imaging techniques, ...), non-seismic information (Joint Inversion with potential fields and EM) and collaboration between different disciplines can benefit and complement site surveys and specific shallow imaging projects in a shallow water environment.
Further discussions can involve on how to extract high resolution information beyond the seismic image from the datasets (Velocities, AVA, Rock Physics parameters, Mechanical parameters).
