Abstract

The decline in oil reserves and the increasing demand for oil and gas energy led to the search for new reserves. The geological structure pattern used to know the pattern of distribution and formation of hydrocarbons traps in the East Java Basin is one of the important information that can be extracted through remote sensing data of multi-polarization system. The multi-polarization system of this study merged the \ Alos Palsar imagery with HH and HV polarization, and Sentinel Image polarized VV and VH. Processing both image data through calibration, multilook, speckle fi ltering, geometric correction and mosaic. Filtered imagery is composite and sharpening. The fi ltering technique use Lee 5x5 kernel fi lter and then continue with 5x5 median fi lter. The results of multi-polarization system image interpretation can be identifi ed by fold, thrust faults, normal faults, strike-slip faults, bedding, and closure structure. In the formation research area the structure lasted two periods, with the main emphasis N-S in the order of 1 and the main direction of the SW-NE direction in the order-2. The hydrocarbon traps and exploration targets can be distinguished in three zones (Zone A, Zone B, and Zone C). Closure in Zone A includes closures 3, 4, 5, 7, 8, 9, 10, 11, 22, 23, 24, 25, 26, 27, 28, 29, 30. Closure in Zone B includes closures 1, 2, 6, 12, 13, 14, 15, 16, 17, 31, 32. Closure on Zone C includes closure18, 19, 20, 21.

Abstract

The oil and gas exploration activities in the last two decades in the mature sedimentary basins in the western area of Indonesia can be said has been in the stagnation phase. The activities are still limited in the effort of discovering shallow structures as the exploration targets which are of Miocene age and not older than Early Miocene. On the other hand, the oil and gas exploration on hydrocarbon plays, as well as new Paleogene sediments or others, has not been done intensively. Some problems which cause difficulty in finding new resources are such as lack of innovation in the exploration activities, and this is because the exploration operators are reluctant to bear the failure risk in the development of exploration activities that they do; which leads the exploration program carried out mainly focused only on the target or objective reservoir that is known. The effort of finding oil and gas resources in the future on the mature basins can be done by reanalyzing and revisit the evaluation on how the historical development of a sedimentary basin, that includes the development process and the tectonic sedimentation during the Tertiary era in relation to the formation of hydrocarbons. The reanalysis should be supported with the latest subsurface data, up-to-date geosciences concepts and sophisticated software and hardware which are able to perform the analysis of petroleum system in order to find new hydrocarbon-play as a new exploration target in the future. Various proposed activities in the re- valuation of the Tertiary sedimentary basins in Indonesia are the analysis of the Paleogene graben system of the back-arc basins of Sumatra and Java, the analysis of Miocene-Pliocene lowstand sediment, and the analysis of Miocene carbonate sediments, which have not been evaluated intensely so far.
