Integration of geology and geophysics through geostatistical inversion: a case study

First Break, 2011
Geostatistical inversion of seismic data can be used to build highly detailed reservoir models with integration of information from diverse sources. A key to successful integration is the solution for facies during the inversion, provided that the facies definition is meaningful in the elastic, petrophysical, geological, and reservoir engineering ...

Geological Structure-Guided Initial Model Building for Prestack AVO/AVA Inversion

IEEE Transactions on Geoscience and Remote Sensing, 2021
Reconstructing an accurate and high-resolution subsurface model is attractive in the fields of both geology and seismology. However, due to the band-limited characteristics of seismic data, the inversion greatly depends on the reliability of the initial ...

Joint Impedance and Facies Inversion of Time-lapse Seismic Data for Improving Monitoring of CO2 Incidentally Stored From CO2 EOR

Social Science Research Network, 2021
Time-lapse seismic monitoring is an effective and proven technology for determining the distribution of CO2 in a subsurface reservoir. When injected CO2 displaces other reservoir fluids, the seismic impedance changes, causing time-lapse seismic amplitude

Gravity data inversion for the basement relief delineation through global optimization: a case study from the Aegean Graben System, western Anatolia, Turkey

, 2020
Aegean Graben System is a significant member of the complex geology of western Turkey. The depths to the metamorphic basement reliefs in two major grabens have been reported by many geophysical studies. However, the sediment thicknesses of these graben
