Abstract: Focused monitoring of a few “spot” locations strategically placed on a CCS field appear as a good candidate for long term monitoring of CO2 storage. However, when compared to regular 4D seismic methods, the sparsity of data may appear as a source of uncertainty, due to the sensitivity of the method to velocity models and placement of sources and receivers on field. In this paper, we show that, when included in the processing chain, uncertainty analysis provides additional information that proves valuable in interpreting the CO2 detection results.
