CONSTRUCTION OF SYNTHETIC SEISMOGRAM IN ABU SUFYAN OIL FIELD

Abstract

The used data in this project consists of 2D seismic line and well data, this data of a good quality. The method of analysis applies (PETREL.2015 software) Tying the seismic data to well data is a major task in interpretation, It is used to correlate the well information (logs) to seismic. Well-seismic ties allow well data measured in units of depth, to be compared to seismic data, measured in units of time, this allows us to relate horizon tops identified in a well with specific reflectors on the seismic section, we have used sonic and density well logs to generate a synthetic seismic trace by extracting the velocity and density from the logs measurements and multiply them to give acoustic impedance, the software compute reflectivity for boundaries and then convolve this reflectivity with the wavelet which extracted from the seismic line, then the synthetic trace is compared to the real seismic data collected near the well location for identifying the reflectors on the seismic line from horizons in the well. This job used to transfer the well information to seismic line (the line in this study is line 2, and the well is Abu sufyan n-3) and then make loops around through the whole area of interest by using this line. The work done in this study is to generate a synthetic seismogram form this data.
