Abstract
This study aims to perform seismic interpretation and carbonate reservoir characterization in the Mantawa Formation using 3D PSDM seismic data and well log data. The methodology includes Well Seismic Tie (WST), horizon and fault interpretation, time and depth structure mapping, time-to-depth conversion (VoK), and seismic attribute analysis such as RMS Amplitude, Envelope, and Relative Acoustic Impedance (RAI).WST results from wells S-02 and S-03 show correlation values above 0.7 indicating that the seismic data is reliable for interpretation. The interpretation reveals a major east–west trending normal ==fault and an anticline structure located in the central part of the study area. This anticline zone is identified as a potential hydrocarbon trap, supported by high RMS Amplitude and Envelope attribute responses as well as its association with the fault system. These findings demonstrate that seismic attribute analysis is effective in delineating structural geometry and identifying prospective carbonate reservoir zones in the Mantawa Formation.

Penelitian ini bertujuan untuk melakukan interpretasi seismik dan karakterisasi reservoar karbonat pada Formasi Mantawa menggunakan data seismik 3D PSDM dan data log sumur. Metode yang digunakan meliputi Well Seismic Tie (WST), interpretasi horizon dan sesar, pembuatan peta struktur waktu dan kedalaman, konversi waktu ke kedalaman (VoK), serta analisis atribut seismik seperti RMS Amplitude, Envelope, dan Relative Acoustic Impedance (RAI). Hasil WST pada sumur S-02 dan S-03 menunjukkan korelasi lebih dari 0,7 sehingga data seismik dapat diandalkan untuk interpretasi. Hasil interpretasi mengidentifikasi struktur utama berupa sesar turun berarah timur–barat dan keberadaan antiklin di bagian tengah area penelitian. Zona antiklin ini berpotensi menjadi jebakan hidrokarbon, yang diperkuat dengan respon atribut RMS Amplitude dan Envelope yang tinggi serta keterkaitannya dengan pola sesar. Temuan ini menunjukkan bahwa penggunaan atribut seismik efektif dalam memperjelas geometri struktur dan zona prospek reservoar karbonat di Formasi Mantawa
