Abstract

TARATARI field, the object of the research is one of oil fields, located on NORTH WEST JAVA basin which is a concession area of PT. PERTAMINA EP. On this field, a study about geology structure that develops in the connection of a hydrocarbon trap. By means of the deepened interpretation of sub surface geology structure, it’s expected to be beneficial for the exploration of hydrocarbon. The data used on this research are seismic data as main data, together with regional data as a supporting data, seismic data are used for structure analysis and sub surface mapping of TARATARI field. Regional geology is very worthy in interpreting sub surface structure on the research area. The method that used in this research are analysis and descriptive. Based on the result of the research, the developing structure on the TARATARI field is dextral fault and anticline. The fault structure on vertical profile figure can be identified with the occurrence of flower structure. The dextral fault has a North-South oriented direction. Hydrocarbon trap formed on TARATARI field is a structural trap which controlled by anticline and fault. Based on result from this research, the structure that happened in area research are strike slip and anticline. Strike slip can showed by flower structure in line seismic. The orientation of Strike slip is North-South. Trap in this research area is structural trapping. The petroleum system in TARATARI field are, source rock is shale from Baturaja Formation and Talangakar Formation. The reservoir are sandstone and limestone from Baturaja Formation and Talangakar Formation. Seal are shale from Baturaja Formation and Talangakar Formation. The migration that happened is vertical and lateral. Based of the time structure contour map on each formation, is obtained the value of enclosure squares. On Baturaja formation the width is 1018 acre, meanwhile on Talangakar formation the width is 968 acre
