Abstract

L Lapangan â€˜Xâ€™ terletak di Sub-Cekungan Tarakan pada daerah Kalimantan Timur. Penelitian ini difokuskan pada formasi tabul pada sub-cekungan Tarakan. Penelitian ini menerapkan konsep sekuen stratigrafi dengan metode korelasi, yang akan memberikan hasil berupa (1) Pemetaan fasies, (2) Penentuan marker sekuen stratigrafi, (3) Analisis Seismik, (4) Analisis Fasies Seismik, (5) Pembuatan Peta SSR, (6) Model Depth Structure dan (7) Model Paleogeografi. Data yang digunakan dalam penelitian meliputi integrasi dari 9 data well log,1 data batuan inti, 1 Side Well Core, dan data seismic. Batas sekuen (SB), maximum flooding surface (MFS), dan marker sekuen stratigrafi lainnya ditentukan dari analisis data well log dan seismik untuk membuat penampang korelasi. Interpretasi lingkungan pengendapan yang didasari oleh analisis lithofasies, elektrofasies dan seismik. Berdasarkan hasil penelitian, pada formasi Tabul di lapangan â€ŸXâ€Ÿ. Diketahui Formasi Tabul memiliki asosiasi fasies yaitu delta plain, delta front, pro delta, braided channel, dan mouthbar. Arah suplai sedimen berasal dari arah relatif barat Utara - Selatan. Melalui marker sekuen yang telah ditentukan, Model Paleogeografi untuk formasi Tabul dibagi menjadi 6 gambaran model pengendapan disetiap marker sekuen stratigrafi. Gambaran model tersebut menunjukkan kondisi dan perubahan morfologi daerah penelitian dari setiap fasenya, yang pertama SB9 menunjukkan model paleogeografi Distributary Channel, Flood Plain, Delta Front, Pro Delta. SB10 menunjukkan model paleogeografi Distributary Channel, Flood Plain, Delta Front, Pro Delta. SB11 menunjukkan model Distributary Channel, Flood Plain, Delta Front, Pro Delta. kemudian SB12 Distributary Channel, Flood Plain, Delta Front, Mouth Bar. Pada Top Tabul menunjukkan model Distributary Channel, Flood Plain, Delta Front, Pro Delta. kemudian SB12 Distributary Channel, Flood Plain, Delta Front, Mouth Bar.

T The 'X' field is located in the Tarakan Sub-Basin in East Kalimantan. This study focused on the tabul formation in the Tarakan sub-basin. This study applies the concept of stratigraphic sequences using the correlation method, which will give results in the form of (1) facies mapping, (2) Determination of sequence stratigraphic markers, (3) Seismic analysis, (4) Seismic facies analysis, (5) Making SSR maps, ( 6) Depth Structure Model and (7) Paleogeographic Model. The data used in the study included integration of 9 well log data, 1 core rock data, 1 Side Well Core, and seismic data.Sequence limits (SB), maximum flooding surface (MFS), and other stratigraphic sequence markers are determined from the analysis of well log and seismic data to make a cross-sectional correlation. Interpretation of depositional environments based on analysis of lithofacies, electrofacies and seismics. Based on the results of the study, in the Tabul formation on the 'X' field. Tabul Formation is known to have facies associations, namely delta plain, delta front, pro delta, braided channel, and mouthbar. The direction of sediment supply comes from the relative north-south direction. Through predetermined marker sequences, the Paleogeographic Model for Tabul formation is divided into 6 deposition models in each stratigraphic sequence marker. The description of the model shows the conditions and changes in morphology of the study area from each phase, the first SB9 shows the Distributary Channel, Flood Plain, Delta Front, Pro Delta paleogeography models. SB10 shows the Distributary Channel, Flood Plain, Delta Front, Pro Delta paleogeography model. SB11 shows the Distributary Channel, Flood Plain, Delta Front, Pro Delta models. then SB12 Distributary Channel, Flood Plain, Delta Front, Mouth Bar. The Top Tabul shows the Distributary Channel, Flood Plain, Delta Front, Pro Delta models. then SB12 Distributary Channel, Flood Plain, Delta Front, Mouth Bar.
