Irrawaddy

Commentary

The IRWDB remains prospective, but civil war, sanctions and the exit of TotalEnergies and Chevron leave no viable route for Western investment. Regulated gas pricing further undermines the basin's attractiveness. Outlook: Negative.

Location

Description

The IRWDB is the southward extension of the Central Burma Basin with a similar geologic setting and tectonic history. However, the effects of compression caused by regional plate collision are less evident, whereas the oblique or strike-slip component becomes more dominant. The key features are that the source and reservoir rocks were deposited in a predominately deltaic and marine environment, and source rocks are more gas prone. Source rock burial depths become greater to the south, and cracking of oil to gas because of greater depths of burial may contribute to the hydrocarbon generation. Traps are primarily anticlines, alluvial channels, deltaic features, and carbonate reefs and pinnacles.

Summary

The IRWDB basin is located on the eastern margin of the Bay of Bengal. While parts of the basin have been more heavily explored, overall the basin contains significant potential, as the majority has been limited by excessive governmental bureaucracy.
