This is a comprehensive course which has a lecture component and a workshop component. Lectures are delivered from 9:00 am until lunch and during the afternoon participants will perform several exercises the aim of which is to familiarize them with carbonate depositional systems, microfacies and reservoir characterization. Participants are highly encouraged to bring-in seismic lines and well-logs from their own work projects.
The fifth day of the course can either focus on reservoir characterization or a 1-day core workshop on your company’s core data. There is also an optional exercise in which participants are taught reservoir characterization using a microscope (this is only possible if microscopes are provided by your company).
Day 1. Controls on carbonate production, dolomitization models and effects on reservoir quality, leaching, dedolomitization and evaporite associations.
Exercise: Modern carbonate depositional environments, facies distribution
Day 2. Carbonate classification of Folk vs Dunham, Reef rock classification, Microbialite classification, microfacies: grain types, textures, and porosity.
Exercise: Describing core and thin sections
Day 3. Carbonate factories of Schlager: T-factory, M-factory and C-factory, carbonate platforms types and associated plays.
Exercise: How to approach a carbonate play by integrating seismic, well logs, and core
Day 4. 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, Carbonate seismology.
Exercise: Identification of key-sequence stratigraphic surfaces
Day 5. Carbonate reservoir characterization: controls on porosity and permeability distribution, fractured carbonate reservoirs OR description of your company’s carbonate core.
Exercise: How to calculate Net:Gross in carbonate reservoirs
Note: Company specific case-studies can be incorporated into class room exercises
Instructor will provide: Course Manuals, paper copies of seismic lines, well-logs, core-photos, hand-outs and thin-sections (if your company chooses the microscope exercise).
Participants should bring: Color-pencils of 3 colors
