Southeast Asian Carbonate Systems & Reservoirs
This training covers Southeast Asian carbonate systems and their reservoirs. It works through the tectonic and oceanographic setting, Cenozoic carbonate system types, buildup initiation and growth, carbonate facies and biota, platform drowning and demise, diagenesis including exposure and karst, reservoir quality distribution, seismic imaging of buildups, the main producing carbonate fields and the exploration and development of carbonate targets in the region.
Description
Southeast Asian carbonates are distinctive. They are young, mostly Oligocene to Miocene, developed in a tectonically active equatorial setting with high subsidence rates, abundant terrestrial sediment supply and frequent relative sea level change. The result is isolated buildups, pinnacle reefs and shelf platforms that grew on structural highs, were repeatedly exposed and flooded, and were eventually drowned or buried by clastics. Each of those features affects their reservoir character.
This training covers these systems and their reservoirs. The tectonic and oceanographic setting is established first, covering the controls that distinguish the region from other carbonate provinces. Cenozoic carbonate system types follow. Buildup initiation and growth are then developed, covering the substrate control and the growth history. Carbonate facies and biota follow, covering the components and their environmental significance. Platform drowning and demise are then addressed, since the mode of termination affects the seal and the top reservoir. Diagenesis including exposure and karst follows in detail. Reservoir quality distribution is then developed. Seismic imaging of buildups follows. The main producing fields are addressed. The training closes with exploration and development.
Buildups initiate on structural highs and that makes them predictable. A carbonate buildup needs a shallow substrate free of clastic input, which in the region means a fault block crest, a volcanic edifice, an inverted structure or an older buildup. Mapping the Palaeogene structural configuration therefore predicts where Miocene buildups should be, and seismic imaging confirms them. This substrate control is why the buildups occur in trends rather than randomly.
Clastic input kills carbonate growth and its timing controls the system. Carbonate production requires clear water, so a buildup grows only while terrestrial sediment is kept away from it, by distance, by water depth or by a structural barrier. When deltas prograded or subsidence brought the buildup into the path of clastic supply, growth ceased. The resulting buildups are therefore often capped and sealed by the clastics that killed them, which is a convenient configuration for trapping.
Repeated exposure created leached porosity and karst, and both help and complicate. Miocene sea level fluctuations exposed buildup tops repeatedly, generating meteoric dissolution, leached porosity, collapse features and in places substantial karst. The leached intervals are excellent reservoir; the karst produces drilling hazards, extreme permeability contrasts and reservoir behaviour that is hard to model. Recognising the exposure surfaces and their distribution is central to both reservoir quality prediction and well planning.
Finally, drowned buildups with a shale drape are the ideal configuration and not the only one. Where a buildup was drowned and then covered by marine shales, the seal is excellent and the trap is complete. Where it was buried by prograding clastics, the seal depends on the mudstone content of the delta front. Where the buildup top was exposed and karstified before burial, the top reservoir surface is irregular and the seal may be breached by collapse features. The termination history therefore determines the trap quality.
By the end of this training, participants will be able to:
- Describe the tectonic and oceanographic controls on regional carbonate systems
- Classify Southeast Asian Cenozoic carbonate system types
- Predict buildup location from substrate and structural configuration
- Interpret carbonate facies and biota in regional buildups
- Interpret buildup growth, drowning and demise histories
- Recognise exposure surfaces, leached porosity and karst
- Predict reservoir quality distribution within buildups
- Interpret the seismic expression of carbonate buildups
- Describe the main producing carbonate fields of the region
- Plan exploration and development of regional carbonate targets
The training works on core, log and seismic data from regional carbonate fields. Participants interpret facies and diagenetic histories, map buildup geometry from seismic, and predict reservoir quality distribution. Production data is used to test the predictions. Karst affected and non-karst intervals are compared for their behaviour.
