Aperçu de Project Overview

One of the primary challenges facing 3D exploration and monitoring seismic technology in the coming 5-10 years is to formulate, validate, and bring on-line the set of procedures known as seismic full waveform inversion (FWI) as applied in onshore (land data) reservoir environments.

The main objective of this project is to develop a 3D field data FWI workflow for structural imaging in the presence of complex topography for land dataset. It targets to remove the presence of high nonlinearity propertiesintroduced by free-surface effects due to presence of complex surface topography. Currently, the modeling engine for 3D FWI has been developed and hopeful we are able move to 3D FWI velocity model building applications in the presence of rugged topography and address the challenges.
