W-18: Advances in Computational Mathematics for Geophysics
Friday, 27 September 8:30 - 12:00 p.m.
Organizers: Tetyana Vdovina and Hugues Djikpesse E-mail Contact: tetyana.vdovina@exxonmobil.com Through the support of the SEG Research Committee
The importance of computational mathematics is increasing with the growing range and complexity of problems that arise from geophysical applications. Computer-based technology has become a vital component in many areas of geophysics, including data processing, seismic imaging and inversion, reservoir modeling, etc. The primary goal of this workshop is to enable in-depth technical discussion on a variety of major computational efforts in geosciences. The workshop will highlight recent developments in:
compressed sensing
numerical methods for modeling of seismic wave propagation
optimization methods for inverse problems
multiscale physics
