Clastic Depositional Systems of Southeast Asia
This training covers the clastic depositional systems of Southeast Asia and their reservoirs. It works through the tectonic and climatic setting, syn-rift lacustrine and alluvial systems, fluvial systems in a tropical setting, tide dominated deltas and estuaries, the Mahakam and Baram delta systems, shoreface and shelf systems, deepwater clastic systems, coal bearing successions, reservoir quality in tropical clastics and the application of regional analogues to reservoir prediction.
Description
Southeast Asian clastic reservoirs were deposited in a humid tropical setting with high rainfall, dense vegetation, strong tidal regimes and rapid subsidence, and they differ systematically from the temperate and arid analogues that much of the sedimentological literature is based on. Tidal influence is pervasive, coals are abundant, chemical weathering is intense, and the resulting reservoirs have particular quality characteristics and architectures.
This training covers these systems and their reservoir implications. The tectonic and climatic setting is established first, covering the controls that make the region distinctive. Syn-rift lacustrine and alluvial systems follow, covering the Palaeogene rift fills that contain both the source rocks and some reservoirs. Fluvial systems in a tropical setting are then developed. Tide dominated deltas and estuaries follow in detail, since tidal processes dominate many of the region's best reservoirs. The Mahakam and Baram delta systems are then addressed as the principal examples. Shoreface and shelf systems follow. Deepwater clastic systems are then developed. Coal bearing successions are addressed. Reservoir quality in tropical clastics follows. The training closes with analogue application.
Tidal influence is the regional signature and it affects reservoir architecture directly. The archipelagic geography amplifies tides, so many of the region's deltas and estuaries are tide dominated rather than fluvial or wave dominated. The resulting reservoirs are tidal bars and channel fills with inclined heterolithic stratification, bidirectional cross-bedding, mud drapes on every bedding surface and a characteristic alternation of sand and mud at bed scale. Those mud drapes are the barriers that control vertical flow.
Coals are abundant and they matter in several ways. The humid tropical climate and high accommodation produced extensive peat accumulation, so Neogene successions across Kalimantan, Sumatra and Sarawak contain numerous coals. They are source rocks generating gas and condensate, they are excellent correlation markers that can be traced over large areas, they are mechanically weak and cause drilling problems, and they are permeability barriers within reservoir successions.
Intense chemical weathering affects the sand composition and its reservoir quality. High rainfall and temperature in the source areas produce deep weathering profiles, which supply quartz-rich sands where the weathering is complete, and lithic and labile sands where the relief is high and erosion rapid. The volcanic arc sources supply abundant volcanic lithics that alter to clays during diagenesis, reducing permeability substantially. The provenance therefore controls reservoir quality strongly, and it varies across the region.
Finally, the Mahakam delta is one of the best studied delta systems in the world and a widely used analogue. Its modern distributary and tidal channel network, its subsurface Miocene equivalents in the Kutei basin fields, and the extensive published work on both make it the reference tide-influenced delta. Using it as an analogue requires understanding which parts of the system are represented in a given reservoir interval, because the delta plain, the distributary channels, the tidal bars and the delta front all have different architectures.
By the end of this training, participants will be able to:
- Describe the tectonic and climatic controls on regional clastic systems
- Interpret syn-rift lacustrine and alluvial systems
- Interpret tropical fluvial systems and their reservoirs
- Recognise and interpret tide dominated deltas and estuaries
- Characterise inclined heterolithic stratification and its flow effects
- Describe the Mahakam and Baram delta systems and their reservoirs
- Interpret shoreface, shelf and deepwater clastic systems
- Interpret coal bearing successions and their significance
- Assess reservoir quality controls in tropical clastics
- Apply regional analogues to reservoir prediction
The training works on core, log and seismic data from regional clastic fields, with modern system analogues from the Mahakam and other deltas. Participants interpret facies and architecture, correlate using coals and flooding surfaces, and predict reservoir connectivity. Predictions are tested against the production and pressure data from the same fields.
