Applying our workflow to a 3D seismic data set with 26 wells achieves consistent and verifiably accurate results. We use blind well tests to verify the accuracy of well-log interpolation and seismic well ties.
Finally, log data from each well are interpolated along local seismic structures to generate global log property volumes. Local similarity is then used to tie available wells with seismic data. We first used the local similarity scan to align all logs to constant geologic time and interpolate missing well-log information. We have developed a workflow to estimate missing well-log information, automatically tie wells to seismic data, and generate a global well-log property volume using data matching techniques.
When sonic and density logs are not available, it is challenging to incorporate wells into integrated reservoir studies because the wells cannot be tied to seismic. Relating well-log data, measured in depth, to seismic data, measured in time, typically requires estimating well-log impedance and a time-to-depth relationship using available sonic and density logs.
