[ABSTRAK Telah dilakukan pengolahan data multicomponent seismic pada komponen radialuntuk menganalisis kualitas data yang dihasilkan oleh S-Wave. Data seismik yangdigunakan pada penelitian ini adalah data multicomponent seismic pada ZonaTransisi yaitu data Ocean Bottom Cable. Pengukuran multicomponent seismicdengan menggunakan tiga komponen (X, Y, Z) dari geophone beserta satukomponen dari hydrophone akan merekam Wavefield seismik lebih lengkap daripada pengukuran secara konvensional.Penelitian ini dilakukan untuk menganalisis hasil pengolahan datamulticomponent seismic pada komponen radial yaitu komponen Y padaGeophone. Pengolahan data pada komponen radial dilakukan dari reformatsampai dengan geometri. Untuk mendapatkan penampang seismik dari gelombangS tidak bisa digunakan pengolahan data menggunakan alur kerja secarakonvensional. ACP (Asymptotic Conversion Point) adalah salah satu prosespengolahan data gelombang S yang paling penting.ACP berhasil menentukan nilai Vp/Vs pada data multicomponent seismic ini.Sehingga dapat digunakan untuk melakukan CCP (Commont Conversion Point)Binning. Sehingga menghasilkan data yang lebih bersih dari noise-noise yangmenunjukkan adanya berbedaan litologi dibawah permukaan bumi, hal iniditandai oleh perbedaan kecepatan perambatan gelombang pada waktu yang sama. ABSTRACT We have processed seismic multi-component data especially on radial componentto analyze data qualities of FractureS-Wave. In this study, the seismic data aremulti-component seismic data on the transition zone. Multi-component seismikmeasurements using three components (X, Y, and Z) of geophones andhydrophones component, they will record seismik wave field more complete thanthe conventional measurements.This study does to analyze the results of multicomponent seismic data processingin the radial component, of the Y component Geophone. The processed on radialcomponent conducted from reformat to geometry. To get a section of the S waveseismic refraction is not use conventional workflow. ACP (AsymptoticConversion Point) is the most important one of the S- Wave data processing.ACP succeeded in determined the Vp/Vs value of multicomponent seismic data.So it can be used to perform the CCP (commont Conversion Point) binning. Sowas produced data was cleaner than noises that were shows different lithology ofsubsurface, it is characterized by wave velocity different in the layer at the sameTWT., We have processed seismic multi-component data especially on radial componentto analyze data qualities of FractureS-Wave.
