Seismic processing by integrated analysis of borehole and surface seismic data

Seismic processing by integrated analysis of borehole and surface seismic data

SEG Abstracts 60: 281-284

We present a special seismic processing sequence supported by a case study, where borehole data and 2-D surface seismic data are combined in some way in order to achieve maximum reliability of the post-stack derived acoustic impedance section. The objective has been to provide reliable, high resolution acoustic impedance or reflectivity sections and to maintain calibration with the well log data at least over the zone of interest. This study is focused on one seismic line on an offshore gas sand reservoir. In this particular case, only borehole data available at one well, located near the seismic line, are used for calibration purposes. The interpretative processing sequence begins with suitably processed borehole data including the inversion of a zero-offset vertical seismic profile (VSP). It continues with a target oriented surface seismic processing calibrated by use of the estimated VSP impedance log. The sequence concludes with an integrated stratigraphic interpretation based on an inversion technique with a priori information. The final result is a reliable acoustic impedance (or reflectivity) section over the zone of interest consistent with all available geologic, borehole and seismic data.
