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...

متن کاملRedatumming 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...
متن کاملNear-surface VSP surveys using the seismic cone penetrometer
We have found that high-quality vertical seismic profile (VSP) data can be collected for near-surface applications using the seismic cone penetrometer. Conemounted accelerometers are used as the VSP receivers, and a sledgehammer against the cone truck baseplate is used as a source. This technique eliminates the need to drill a borehole, thereby reducing the cost of the survey, and results in a ...
متن کاملTradeoffs in the Application of Time-Reversed Acoustics to Tactile Stimulation
The creation of active tactile surfaces through electromechanical actuation is an important problem. We describe here the application of time-reversed acoustics to the creation of deformations localized in time and in space in a stretched membrane that can be touched. We discuss the basic physical and engineering tradeoffs of this approach and describe the results obtained from an experimental ...
