Interpretation of well log, VSP, and streamer seismic data from the White Rose oilfield, offshore Newfoundland
A multi-offset-VSP dataset was acquired in Husky Energys H-20 well in the White Rose field, (Jeanne-dArc basin, offshore Newfoundland). The processing of the multi-VSP dataset acquired by Husky Energy Inc. was conducted by Schlumberger Canada Ltd and generated various outputs such as corridor stack,...

| Summary: | A multi-offset-VSP dataset was acquired in Husky Energys H-20 well in the White Rose field, (Jeanne-dArc basin, offshore Newfoundland). The processing of the multi-VSP dataset acquired by Husky Energy Inc. was conducted by Schlumberger Canada Ltd and generated various outputs such as corridor stack, CDP mapping of PP data and of PS data. The interpretation of the results from the multi-VSP data is in this paper. The best correlations are between the PS synthetic seismograms and the PS offset VSP data. The PS images from these synthetic seismograms are better at the top of the Avalon Formation showing higher amplitude over the adjacent signals. There are good correlations between PS synthetic seismograms generated from well logs and the PS offset VSP data. The PS images from these synthetic seismograms are better at the top of the Avalon Formation showing higher amplitude over the adjacent signals. There were several wavelets with different frequency content that were used to obtain the best match possible; the final wavelet used was a 45-Hz zero-phase Ricker wavelet. Synthetic and field data indicate that converted-wave (Ps) data may be useful in mapping the Avalon reservoir at White Rose. |
