The Analysis of Application Seismic Interferometry to Interpolate Missing Seismic Data

Abstract

Abstract

The recovery process of missing seismic data has been conducted by using seismic interferometry principal. This research is designed to examine the ability of seismic interferometry to interpolate two kinds of 2D seismic data and composed to have various qualities which is termed as “higher quality” and “lower quality” data. Also, it is categorized into synthetic data “higher quality”, synthetic data “lower quality” and field data “lower quality”. By cross correlation of traces and followed by summation over all shot gathers in seismic interferometry will produce virtual traces and it is used to fill some gaps in data. The first justification will employ to score qualitative parameter to see the continuity and consistence the optimum primary reflector of ability of seismic interferometry to reconstruct data and completely, it also will be considered to obtain the value of correlation of interpolation result as the quantitative justification. According to the result, the primary reflector for synthetic “higher quality” is be able to yield the optimum reconstruction up to 50% and it corresponds to value of correlation obtained is 0.9508 (strong). Furthermore, it is contrast to the synthetic and field data “lower quality” which only can give the optimum interpolation up to 30% with correlation value repeatedly are 0.4477 and 0.4193 (moderate), which is characterized that interpolation result of seismic interferometry exactly attenuated multiple.
