Reservoir Characteristics of Shoreline Delta Clinoforms and Subaqueous Delta Clinoforms of Irrawaddy Delta

The reservoirs deposited during the Pleistocene age are the result of a series of transgressive and regressive movements of the Irrawaddy Delta. The concept of compound clinoforms, comprising subaqueous delta and shoreline delta formations, can be applied to both modern and ancient Irrawaddy Delta settings. Facies associated with the shoreline delta include distributary channels and tidal channels, as well as mouth bars. These features are characteristic of the dynamic depositional environment near the coastline.

In contrast, reservoir facies within the subaqueous delta are primarily composed of sand ridges influenced by tidal currents on the shallow marine shelf. These sand ridges represent significant sedimentary features deposited in the subaqueous portion of the delta, contributing to potential reservoir formations.
