Calibration of Depth Processed Seismic to Well Markers

The following workflow has been implemented successfully by Petrobras in one of their deepwater reservoirs offshore Brazil. As part of the development strategy, most new wells drilled in this field are either highly deviated or horizontal. Given the very high associated costs, it is critical to accurately predict the depth to top reservoir.

The methodology and results of this study are discussed in greater detail in the following paper: Daltro, D. et al, "A calibration method for depth imaged volumes," presented at the 8th International Congress of the Brazilian Geophysical Society (Rio de Janeiro, September 2003).
