| Abstract: | In QK17 2 oilfield, the top reservoir reflection is defined as a strong amplitude peak by creating synthetic seismogram using drilling, logging and seismic data. The development of faults can be accurately interpreted with a 3D coherence analysis. The application of horizontal amplitude slices and 3D visualization technique can be used to describe spatial distribution of the sand beds. The logging constrained impedance inversion has improved the seismic resolution, by which the single sandbody geometry and its lateral variation in thickness and petrophysics can be described. All these have provided an accurate target location for the extended horizontal well in the field and directed its drilling at any time, ensuring success of the first extended horizontal well in Bohai Sea. |
