WebOct 19, 2024 · Compared with the FrontSim model, the INSIM-FPT-3D model after history matching is shown to match the dynamic PVs from FrontSim reasonably well and can correctly predict the timing of water breakthrough. By allowing for the assimilation of BHP data, we enable INSIM-FPT-3D to history match a green field with limited production … WebDynamic-warping FWI where D is the observed data and P M is the synthetic data predicted by the model M. When the initial model M is far from the correct one, conventional FWI cannot converge from P M to D when there is a lack of low frequency signal in the seismic data. In fact, cycle skipping occurs when the
WebSep 1, 2016 · Dynamic Warping FWI (Wang et al., 2016) was run using diving waves in a frequency marching manner from 4 Hz to 12 Hz. This was followed by HF-FWI to 24 Hz by also incorporating reflections (Kumar ... WebFeb 1, 2024 · Dynamic matching FWI (DMFWI) is a newly developed algorithm that solves an inversion problem that maximizes the cross correlation of two dynamically matched data sets — one recorded and the other synthetic. Dynamic matching of the two data sets de-emphasizes the amplitude impact, which allows the algorithm to focus on minimizing their ...
