WebIt is useful to run a sparse spike inversion first, to establish this. Out of the range of the wells, we use geostatistical inversion to constrain the simulations. ... Figure 1: An example line from the constrained sparse spike inversion. The areas of low impedance below the Swan Hills horizon represent porosity. Figure 2: A line from one of ... WebIn order to investigate the potential for locating additional hydrocarbon reservoirs, well log data was used and the Penobscot 3D seismic dataset was analyzed using Constrained Sparse Spike Inversion. From the well log data, low GR and SP values are an indication of a permeable sand layer, which provides the target zone in this study.

Wavelet analysis was done separately for the P-P and P-S data. In each case, the seismic data were matched to the appropriate impedance logs at the wells and wavelets estimated. The P-P and P-S wavelets were close to zero phase. The inversion methodology described above was used to compute both Pop and … margherita cerri
