Hydrocarbon distribution in the West Java Basin is primarily controlled by source rock distribution during subsidence. Tectonic development and magmatism influence hydrocarbon generation and accumulation in this petroleum province.
Area of Science:
- Geology
- Petroleum Geoscience
- Tectonics
Background:
- The West Java Basin is a significant petroleum province in Southeast Asia.
- Recent discoveries indicate a rise in new hydrocarbon reserves.
- Understanding resource distribution and tectonic evolution is crucial for exploration.
Purpose of the Study:
- To systematically explore hydrocarbon resource distribution and tectonic evolution in the West Java Basin.
- To analyze the main controlling factors of hydrocarbon distribution.
- To delineate oil and gas formation and distribution across different blocks.
Main Methods:
- Analysis of tectonic evolution characteristics.
- Investigation of source rock distribution and its influence on sedimentary facies.
- Assessment of heat flow and magmatism impacts on hydrocarbon generation.
- Delineation of oil and gas types and their distribution.
Main Results:
- Hydrocarbon distribution is uneven, primarily controlled by source rock distribution during subsidence.
- A
- three-stage
- tectonic development process influences source rock and sedimentary facies distribution.
- Crustal weakening and magmatism enhance heat flow, accelerating hydrocarbon generation.
Conclusions:
- Source rock distribution during subsidence is the main control on hydrocarbon patterns.
- Tectonic development and magmatic activity are key factors in hydrocarbon generation.
- Prospective exploration areas include south-central shallow-deep water zones and underexplored terrestrial regions.
