* Categorization based on the prospectivity
of the basin as presently known. The four recognized
categorie are basins which have:
- Established commercial production
- Known accumulation of hydrocarbons but no
commercial production as yet
- Indicated hydrocarbon shows that are considered
geologically prospective
- Uncertain potential which may be prospective
by analogy with similar basins in the world.
This categorization will necessarily change with the results
of further exploration.
