ABSTRAK
Seismic sequence stratigraphy analysis was performed to identify a chronostratigraphic evolution of submarine fan reservoir in Pari field, Makassar Strait, offshore East Kalimantan. A complete sequence stratigraphy in Pari field was divided into three systems tract: lowstand systems tract (LST), transgressive systems tract (TST) and highstand systems tract (HST). The ?X? reservoir unit was deposited during the lowstand systems tract (LST). Based on core data and well log, the reservoir is dominated by few massive thick sandstone, thin interbedded sandstone and shale. Well data and 3D seismic multiattribute analysis indicated a submarine fan depositional system feature. However, the available 3D seismic data could not image the submarine fan elements feature like channels and splay lobes due to low seismic resolution. A shallow Pleistocene submarine fan located in the northern part of the study area is clearly imaged using 3D seismic data. That Pleistocene submarine fan provides analog dimensions for sub-seismic reservoir elements in the ?X? reservoir unit, Pari field. The dimensions of channels and splay lobes within Pleistocene submarine fan were used to define stochastically reservoir elements in Pari field. The Pleistocene submarine fan are approximately the same size as the seismically mapped the ?X? reservoir unit. Three facies model were generated to provide multiple realizations of facies model. Those are 70% channel and 30% splay lobe (more channels dominated), 50% channel and 50% splay lobe (proportional between channel and splay lobe), and 30% channel and 70% splay lobe (more splay lobe dominated).

ABSTRACT
Studi tentang lingkungan pengendapan adalah salah satu tujuan dari banyak penelitian yang dilakukan unuk tujuan akademis dan tujuan ekonomis dalam eksplorasi minyak dan gas. Studi tentang lingkungan pengendapan membutuhkan analisis yang cukup komprehensif untuk analisis fasies sequence stratigraphy guna memperoleh interpretasi yang mendetail. Tujuan dari penelitian ini adalah untuk menganalisis penampang seismik dan juga menggunakan atribut seismik untuk menentukan kerangka sikuen syn-rift, arsitektur endapan syn-rift, dan sistem pengendapannya di Formasi Talang Akar TAF Area Pondok Makmur, Ciputat, Cekungan Jawa Barat Utara. Analisis yang dilakukan dalam penelitian ini adalah interpretasi fasies seismik berdasarkan korelasi penampang seismik dan atribut seismik Spectral Decomposition.

ABSTRACT
Study about depositional environment is one of the purpose of many researches which are done for academic and economic purpose in oil and gas exploration. This study needs enough comprehensive analysis for sequence stratigraphy facies analysis to generate more detail interpretation. The purpose of this research is to analyze seismic sections and by using seismic attributes to define syn rift sequence framework, syn rift deposition architecture, and its depositional system in Talang Akar Formation TAF Pondok Makmur Area, Ciputat, North West Java Basin. Analysis done in this research is seismic facies interpretation based on seismic sections and depositional environments interpretations based on seismic sections and seismic attribute Spectral Decomposition correlation.
