In the E&P industry, AVO inversion is a well-established methodology to derive reservoir properties from seismic data. Traditionally, this method is based on a linearisation of seismic wave-propagation, meaning that the used data model assumes primary reflections only. In this webinar the co-founders of Delft Inversion, Peter Haffinger and Panos Doulgeris, will present a wave-equation based AVO technology. WEB-AVO iteratively solves the wave-equation and accurately models complex wave-propagation including multiple scattering and mode conversions over the target interval. As a consequence, quantitative reservoir properties can be derived from band-limited seismic data. Another unique aspect of WEB-AVO is that it solves directly for reservoir models in terms of compressibility (inverse of bulk modulus) and shear compliance (inverse of shear modulus). These parameters turn out to be much more suitable to detect changes in reservoir fluids and lithology than what can be achieved with conventional parameterisations, e.g. acoustic impedance, shear impedance, Vp/Vs. Over the last years, it was successfully demonstrated how these technical benefits can be translated into added commercial value for exploration, development and production of
subsurface resources. The presentation will include a company overview, a high-level explanation of the technology and a number of case studies from different geological plays.

Panos Doulgeris, Phd Peter Haffinger, PhD
Peter Haffinger and Panos Doulgeris both received a Ph.D. in Geophysics from Delft University of Technology. After becoming co-founders of Delft Inversion in 2013, Peter and Panos constantly challenge themselves to combine their technical background in geoscience with on the fly training in entrepreneurship. With the team of Delft Inversion they are establishing the next-generation AVO technology by bringing the wave-equation into the field of seismic reservoir characterisation. While Delft Inversions proprietary WEB-AVO technology was originally developed with a focus on E&P applications, currently the company is also extending their technology offering to the Geothermal and CCUS industries.
