How are basins classified?
How are basins classified?
Basins are classified by their tectonic setting (divergent, convergent, transform, intraplate), the proximity of the basin to the active plate margins, and whether oceanic, continental or transitional crust underlies the basin. Basins formed in different tectonic regimes vary in their preservation potential.

✓ Category-II Basins: having contingent resources which are yet to be converted to recoverable reserves and commercial production. ✓ Category-III Basins: having prospective resources with no hydrocarbon discovery and few exploration inputs and data.
What is Intracratonic basin?
Intracratonic sag sedimentary basins occur in the middle of stable continental or cratonic blocks. A depression, which can be of the order of 600 m, can be formed at the earth’s surface; this depression, when loaded with sediment, will form a sedimentary basin of the order of 2.5 km thick.
What are Category-II basins?
Similarly, Category-II basins cover 23% of total basinal area, holding 9% of the total hydrocarbon in-place. Five basins fall in this category and those are namely Saurashtra, Kutch, Vindhyan, Mahanadi and Andaman.

How sedimentary basins are formed?
Sedimentary basins are formed over hundreds of millions of years by the combined action of deposition of eroded material and precipitation of chemicals and organic debris within water environment.
