Abstract

The recovery process of missing seismic data has been conducted by using the seismic interferometry principle. 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. In addition, it is categorized into synthetic data higher quality, synthetic data lower quality and field data lower quality. Cross correlation of traces, which is followed by summation over all shot gathers in seismic interferometry, produce virtual traces that will be used to fill gaps in data. First justification employed to score the qualitative parameter is to see the continuity and the consistency of optimum primary reflector reconstructed by interferometry. Second is to obtain optimum value of correlation of interpolation result, which is considered as quantitative judgment. According to the result, the primary reflector from first synthetic data, which has better quality, produces optimum reconstruction of up to 50%. The result from synthetics data corresponds to correlation value of 0.9508, which is suggested as very strong correlation. Contrary to the previous, the field data, which has worse quality results in optimum interpolation of only 30% maximum. The latter corresponds to correlation value of only 0.4193 and 0.4477. Results from field data indicated that interpolation by interferometry could support attenuation of multiple
