ABSTRAKTelah dilakukan pengolahan data multicomponent seismic pada komponen radial
untuk menganalisis kualitas data yang dihasilkan oleh S-Wave. Data seismik yang
digunakan pada penelitian ini adalah data multicomponent seismic pada Zona
Transisi yaitu data Ocean Bottom Cable. Pengukuran multicomponent seismic
dengan menggunakan tiga komponen (X, Y, Z) dari geophone beserta satu
komponen dari hydrophone akan merekam Wavefield seismik lebih lengkap dari
pada pengukuran secara konvensional.
Penelitian ini dilakukan untuk menganalisis hasil pengolahan data
multicomponent seismic pada komponen radial yaitu komponen Y pada
Geophone. Pengolahan data pada komponen radial dilakukan dari reformat
sampai dengan geometri. Untuk mendapatkan penampang seismik dari gelombang
S tidak bisa digunakan pengolahan data menggunakan alur kerja secara
konvensional. ACP (Asymptotic Conversion Point) adalah salah satu proses
pengolahan 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 yang
menunjukkan adanya berbedaan litologi dibawah permukaan bumi, hal ini
ditandai oleh perbedaan kecepatan perambatan gelombang pada waktu yang sama.
ABSTRACTWe have processed seismic multi-component data especially on radial component
to analyze data qualities of FractureS-Wave. In this study, the seismic data are
multi-component seismic data on the transition zone. Multi-component seismik
measurements using three components (X, Y, and Z) of geophones and
hydrophones component, they will record seismik wave field more complete than
the conventional measurements.
This study does to analyze the results of multicomponent seismic data processing
in the radial component, of the Y component Geophone. The processed on radial
component conducted from reformat to geometry. To get a section of the S wave
seismic refraction is not use conventional workflow. ACP (Asymptotic
Conversion 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. So
was produced data was cleaner than noises that were shows different lithology of
subsurface, it is characterized by wave velocity different in the layer at the same
TWT., We have processed seismic multi-component data especially on radial component
