| Summary: | Indonesia is a country that has a large sea area because two-thirds of its territory is sea. One
of them is the Java Sea. Every sea in Indonesia has different depths and characteristics and
has a high potential for marine resources, especially in the waters of the Java Sea. In these
waters there are sedimentary basins, including Sunda and West Java. Based on the condition
of the potential for hydrocarbons in this basin, exploration activities have been carried out to
find existing resources. In order to develop and increase oil and gas recovery, this research
will carry out 3D modeling of magnetic bedrock in the waters of the Java Sea using the
MATLAB-based MagB_Inv program with magnetic anomaly data. This program can estimate
the 3D geometry of the subsurface interface from each magnetic anomaly value and find out
information on the depth and shape of the magnetic bedrock. This research resulted in the 3D
modeling of magnetic bedrock in the waters of the Java Sea, with an average depth of 6.1 km.
The bedrock in the research waters consists of andesite and basalt igneous rocks of Middle
Cretaceous to Upper Cretaceous age and metamorphic rocks of Pre-Tertiary age. 3D
modeling identified the shape of the Sunda sub-basin and the Ardjuna sub-basin with many
variations in relief, and these basins have complex shapes |
