This paper presents the preliminary results of a research project conducted by the Geological Department of Bandung Institute of Technology under a Research Grant Program of PERTAMINA. Using geohistory analysis and backstripping methods, subsidence curves of North Sumatra, South Sumatra, Northeast Java, Barito, and Salawati basins are constructed based on well data supported by biostratigraphy and seismic information. These are explained by the different tectonic settings, the type of lithospheric substratum, proximity to a plate margin, and type of plate boundary (divergent, convergent, or transform) nearest the basin. Studies of subsidence curves form the initial stage for basin modeling. This paper will review basin modeling and applications, particularly in predicting petroleum sy tems of basins, oil/gas windows, maturation of source rocks, migration pathways, etc.
