Utilizing Previous HitseismicNext Hit data with high resolution properties is necessary for detailed and accurate delineation of potential reservoir. But, generally, the available bandwidth of the data is inadequate to image or resolve the thickness of many thin targets seen in wells. Therefore, need a method to improve Previous HitverticalNext Hit Previous HitseismicNext Hit resolution.

This final project tests some methods to increase Previous HitseismicNext Hit resolution with high frequency enhancement technique using Reflection Coefficient Log data and VSP (Previous HitVerticalNext Hit Previous HitSeismicNext Hit Previous HitProfilingNext Hit) data. Basically, three methods are using matching filters principle. First method is based on matching filters between an average Previous HitseismicNext Hit spectra and VSP corridor stack spectra, named as Spectral Matching. Second method is based on matching filters between an average Previous HitseismicNext Hit spectra and Reflection Coefficient Log spectra, named as Spectral Blueing. Third method is based on shaping desired spectrum using average Previous HitseismicNext Hit spectra as a reference, named as Spectral Shaping.

Those three methods were applied to migrated Previous HitseismicNext Hit volume. Result shows more detail reflection, increase Previous HitseismicNext Hit bandwidth, resolve the thickness of many targets seen in wells and better match corridor stack. In the final stage, it is considered best method to enhance Previous HitseismicTop data resolution.
