Simultaneous Estimation of Reflectivity and Geologic Texture: Least-Squares Migration with a Hierarchical Bayesian Model
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)In many geophysical inverse problems, smoothness assumptions on the underlying geology are utilized to mitigate the effects of poor resolution and noise in the data and to improve the quality of the inferred model parameters. ... -
Using Image Warping for Time-lapse Image Domain Wavefield Tomography
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)Time-lapse seismic data are widely used for monitoring subsurface changes. A quantitative assessment of how reservoir properties have changed allows for better interpretation of fluid substitution and migration during ... -
Double-Difference Waveform Inversion of 4D Ocean Bottom Cable Data: Application to Valhall, North Sea
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)Changes in reservoir properties resulting from extracting hydrocarbons and injecting fluid are critical to optimize production. These properties can be characterized using waveform inversions of time-lapse seismic data. ...
