I. Controls on carbonate production, effects of temperature, latitude, depth, salinity and the distribution of reservoir facies.
Carbonate Microfacies: classification schemes of Dunham and Folk, reef rock classification, microbialite classification, the concept of microfacies and introduction to non-skeletal (cortoids, ooids, pisoids, oncoids, grapestones, intraclasts, extraclasts) and skeletal (coral, bryozoans, algae, molluscs, forams and more) grain types, and carbonate matrix.
II. Exercise: Modern carbonate depositional environments, facies distribution
I. Introduction to carbonate factories and builders through time, carbonate platforms types (isolated, rimmed attached, attached, and ramps) and their reservoir distribution. T, C and M factories of Schlager.
Carbonate sequence stratigraphy and cyclicity: shelf cycles of ramps, Lofer and Latemar cycles, Brining upwards cycles, recognition of stratal discontinuities in core, well-logs and seismic.
Exercise: Describing core and thin sections
I. Carbonate Diagenesis: Cement types, positive and negative effects of dolomitization on reservoir quality, and dedolomitization.
Carbonate Ichnology, bioturbation index and ichnofacies.
Reservoir Characterization and the classification of pore systems.
Exercise: How to approach a carbonate play by integrating seismic, well logs, and core.
I. Field trip to modern carbonate depositional environments in either Abu Dhabi (ramp setting) or Bali (rimmed attached shelf)
Exercise: Identification of key-sequence stratigraphic surfaces
I. Seismic Expression of Carbonate Platforms
Exercise: How to calculate Net: Gross in carbonate reservoirs
This course will be taught in Bali, Indonesia between November 6-10, 2021
