ABSTRAK

Pada penelitian ini telah dilakukan migrasi sebelum stack metode Kirchhoff dengan domain waktu dan kedalaman. Pre stack time migration (PSTM) dan pre stack depth migration (PSDM) menghasilkan penampang seimik dengan keunggulan dan kekurangan masing-masing. PSTM menghasilkan penampang seismik dengan reflektor yang lebih fokus tetapi kemenerusan kurang kontinyu. PSDM menghasilkan penampang seismik dengan kemenerusan reflektor yang baik tetapi kurang fokus. Dari segi kemenerusan reflektor, PSDM lebih cocok diaplikasikan pada data seismik 2D lapangan ‘Y’ Cekungan Jawa Barat Utara. Hal ini karena daerah penelitian ini memiliki struktur geologi dan statigrafi yang kompleks.

Kata kunci : stacking, migrasi, PSTM dan PSDM

Abstract

Pre stack migration using the Kirchhoff method in time and depth domains has been conducted. The seismic cross-section produced by the pre stack time migration (PSTM) and pre stack depth migration (PSDM) has certain advantages and disadvantages. The reflector of the cross-section from the PSTM more focuses but less continuity. On the other hand, the PSDM yields the cross-section with better reflector continuity but less focus. Thus, in terms of reflector continuity, the PSDM is more proper used in 2D seismic data of 'Y' field, North West Java Basin. This is due to the basin having complex geologic structure and stratigraphy.

Keywords : stacking, migration, PSTM and PSDM
