<![CDATA[Since 1980 the nuniber of Indonesian Sedimentary Basin which is officially announcedby the government are 60 basins, but informally the variation in the range of less than 60up to around 66 basins. Based on stratigraphic and tectonics conditions of some areasthere are overlapping layers between Tertiary Sedimentary and Pre Tertiary Basin. In general the definition of a sedimentary basin is a region, part of the earth's crustwhere sedimentary strata have been deposited in a relatively much greater thickness thanits surrounding area. The nomenclature for basin is referred more to basinal areas. Basedon sedimentary basin classification there are: type of plate where basin exists, basin posi-tion in the plate margin, type of plate interaction, tinie development of basin and basins fiilwith respect to tectonic and shape of the basin. The updating classification using new technology and knowledge of the basin, canalso update previous knowledge because of the limitation of the data and the lack of newconcept when the report was published. 63 Tertiary Sedimentary Basins (16 producing basin of oil and gas, 8 drilled basin withdiscovery, 15 drilled basin with has no discovery yet and 24 basin which has not beendrilled yet) could be used as a basic data for development of Science and technology, tosupport government policy and investor, to improve and accelerate oil and gas explorationand production in Indonesia.]]>
