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.
