Evaluation of elastodynamic interferometric redatuming: a synthetic study on salt dome flank imaging

Imaging Salt Dome Flank and Dipping Sediments using Time Reversed Acoustics

In this paper we define the theory and basic principles to move (redatum) the surface shots from a walk away VSP to be as if they had been located in the borehole. We will refer to this theory using several of the terms used in the literature including Time Reverse Acoustics (TRA), Seismic Interferometry (SI) and Virtual Source (VS) technology. Regardless of the name, the theory is built upon r...

Estimation of Imageable Dip Range of Target Structures in Interferometric Salt Flank Imaging with Limited Illumination

Salt Flank Delineation by Interferometric Imaging of Transmitted P-to-S Waves

We describe how VSP interferometric imaging of transmitted P-to-S (PS) waves can be used to delineate the flanks of salt bodies. Unlike traditional migration methods, interferometric PS imaging does not require the migration velocity model of the salt or upper sediments in order to image the salt flank. Synthetic elastic examples show that PS interferometric imaging can clearly delineate the up...

Redatumming through a Salt Canopy – Another Salt Flank Imaging Strategy

We describe a new short cut strategy to image the sediments and salt edge around a salt flank through an overburden salt canopy. We demonstrate its performance and capabilities on a synthetic acoustic seismic data from a Gulf of Mexico (GOM) style model. In this strategy, we first redatum the surface shots from a walk away Vertical Seismic Profile (WVSP) survey to be as if the source and receiv...
