LITHOS is a joint initiative by the Institut de Physique du Globe de Paris (IPGP) and the Department of Earth Sciences at the University of Cambridge to develop new integrated waveform modelling and inversion techniques to quantify sub-surface lithology and fluids. We are particularly focused on the full wavefield inversion of data from multi-component ocean bottom seismometers (OBC, OBS) that can record both high frequency controlled source data and passive low frequency signals on the seafloor. LITHOS uniqueness lies in combining near offset wide-angle data. Such data provide quantitative information on P- and S-wave properties at different length-scales, which we believe are key to mapping and defining sub-surface lithology and fluids.

The LITHOS group has unique expertise and capabilities in full wavefield elastic time-domain inversion. Application of wavefield inversion to multi-component OBC field data to address high resolution problems, reservoir characterization and time-lapse (4D) will be the key area of research, whilst we also continue to develop our sound background in tomography and innovative processing ideas, many via the tau-p domain.

The Department of Earth Sciences at Cambridge and IPG Paris provide a stimulating international environment for the development of LITHOS. LITHOS members enjoy direct collaboration with our industry sponsors in terms of scientific exchange, high quality industry data and recruitment of students and post-doctoral workers.
