The focus of our study is lithology/fluid inversion with spatial coupling from prestack seismic amplitude variation with offset AVO data and well observations. The inversion is defined in a Bayesian setting where the complete solution is the posterior model. The prior model for the lithology/fluid LF characteristics is defined as a profile Markov randomfield model with lateral continuity. Each ...

Understanding subsurface flow, especially in fractured rocks only housing water through a few preferential pathways, is still challenging. The point mainly associated with the poor accessibility of and lack accurate representations for both heterogeneity spatial distribution bearing bodies. This notwithstanding, highly-resolved geophysical investigations bring new images subsurface. exemplified...

An important part of any CO2 geosequestration project is to ensure containment and conformance in the subsurface. This generally done by implementing a comprehensive, risk-based Measurement, Monitoring Verification plan, key element which active time-lapse seismic monitoring. However, high cost environmental impact standard surface monitoring dictate need for cost-effective environmentally frie...

Abstract. Geothermal exploration will help move towards a low-carbon economy and provide basis for green sustainable growth. The development of new practical, reliable methods geophysical characterization reservoir has the potential to facilitate broader application deep geothermal energy. At Groß Schönebeck in situ laboratory, unique vertical seismic profiling (VSP) dataset was recorded two 4....

In this study, we propose a heterogeneous transcoding method of converting an H.264/Advanced video coding (AVC) Baseline profile (BP) video bitstream into an MPEG-4 Visual simple profile (VSP) video bitstream. The proposed method reduces the spatial resolution for mobile terminals, which support only low resolution video bitstreams. When the H.264/AVC BP video bitstream is transformed into the ...

Seismic interferometry has become a technology of growing interest for imaging borehole seismic data. We demonstrate that interferometry of internal multiples can be used to image targets above a borehole receiver array. By internal multiples, we refer to all types of waves that scatter multiple times inside the model. These include, for instance, interbed, intrasalt, and water-bottom multiples...
