... Seismic reservoir characterization is typically limited by the bandwidth of the seismic signal. Signal interference, or tuning, impacts our ability to resolve reservoir architecture and estimate properties at a scale commensurate with the geologic layering. Under certain assumptions, we can use...

... be considered a type of self-simultaneous sourcing, where a source interferes with itself. Self-simultaneous sourcing also provides an opportunity to collect denser data than would be possible with conventional acquisition by decreasing the source interval. While this produces high amplitude signals on top...

... irregularities in the source times that produce incoherencies in the interference between sources. It should also be noted that since data coherency is a local attribute, the irregularities in the source times must be maintained locally. The use of random numbers for the dithering creates a problem since random...

.... This solution can fuzz sharp formation boundaries and introduce spurious formation interferences, which poses a serious challenge to the accurate identification of reservoirs. To handle the above issues, we propose a robust MAVA inversion method based on elastic L1/2 norm. Concretely, we construct a robust MAVA...

... The high productivity blended acquisition technique greatly improves the acquisition efficiency. However, this also introduces serious interference noise from adjacent sources. An deblending method based on sparse inversion is used to separate the effective major source signal from the massive...

... for qualitatively characterizing large-scale reservoir connectivity with multiple wells using only injection data. The method can help determine time-dependent interwell communication and perform field-wide analysis by simultaneously analyzing interferences from multiple wells, making it useful for subsurface...

... separation technologies exist to deblend the data, but many of these technologies rely on coherent noise attenuation techniques that produce results with a substantial amount of seismic interference residual noise. In addition to the quality limitations, coherent noise attenuation techniques require...

..., such correlation can be impacted by interference of signals from different well activities at each bin in the correlation map and this leads to ambiguous interpretation. Therefore, we propose a progressive correlation that assesses the relevancy of 4D seismic changes from each well, to provide a complete picture...

The non-Gaussian character of the blending noise points to denoisers that have strong noise reduction capabilities associated with robust...
