Genetic Full Waveform Inversion to Characterise Fractures

81st EAGE Conference and Exhibition 2019, 2019
Understanding the physical properties of fractures, location, orientation, and geometry is of primary importance in the comprehension of geo-resources and geo-hazards. In doing so seismic waves can be an effective tool for non-invasive investigation of fracture parameters.

Full Waveform Seismological Advances for Microseismic Monitoring

2015
Abstract The observation of microseismicity has raised the interest of the seismological and geoengineering communities in the last decades, and a significant effort has been spent to develop or improve methodologies able to perform seismological analysis for weak events at a local scale.

Reflection full waveform inversion

2016
The Full Waveform Inversion (FWI) gradient is composed of a low wavenumber tomographic component and a high wavenumber migration component. A successful application of FWI requires that the low wavenumber parts of the model be recovered before the high wavenumbers.

Simulating full-waveform LIDAR

2012
LIDAR (LIght Detection And Ranging) is used to remotely measure the threedimensional shapes and arrangements of objects with high efficiency and accuracy by making precise measurements of time-of-flight of pulses of light. Discrete return LIDAR systems provide a discrete series of elevation points corresponding to reflections from objects in the scene.
