UNLOCKING THE REMAINING POTENTIAL OF CENOZOIC AGGRADED CARBONATE PLATFORMS IN SE ASIA

摘要

Cenozoic aggraded platforms make up the reservoir component of some of the most prolific hydrocarbon plays in SE Asia. The plays are characterised by carbonate buildups that are today found in basins ranging from onshore to deepwater. Examples include the major oil and gas provinces of East Java, Natuaa and North Sumatra. These plays have variable exploration maturity and are under-explored where the buildups lie in deepwater Neogene basins because the play is very difficult to derisk without drilling. This paper represents a discussion around pre-cursor tectonic and depositional settings for platform development, building on a scheme published by Bosence (2005) but applying it to associated Cenozoic petroleum systems. The scheme maps reasonably well on to Cenozoic build-up plays in SE Asia and can be used to help identify and de-risk future potential in the region.
