Course description

De-risking Carbonate Exploration

This is a “what you really need to know about carbonates” course, in order to attempt to de-risk carbonate prospects. Carbonate rocks are complex; however, there are basic principles that provide a framework in which such complexity may be rendered understandable. The course focuses on large scale rules, risks, uncertainties, strategies and workflows, with a heavy emphasis on seismic facies. It does not focus on appraisal or development aspects.

Suitability - Who should attend?

This course is really aimed at explorationists with at least a basic knowledge of carbonates but will also prove useful to more experienced geoscientists by providing a synthesis of recent advances in understanding carbonate reservoirs, supported by potentially highly practical methodologies for framing uncertainties for reservoir presence.

Outcome / Qualification etc.

  • Frame likely carbonate plays in relation to a given stratigraphic age and basin type.
  • Identify the main types of carbonate platform as seen from seismic data, de-risk certain types of features and assess the likely presence of key seismic facies.
  • Evaluate for a given interval and platform type the likely reservoir facies (platform interior, carbonate sands, reefs, slope systems and chalks) and assess the likelihood of reservoir presence.
  • Understand how the development of primary and secondary porosity has varied through geologic time and how these changes impact upon reservoir quality.
  • Appreciate the principal modes of formation of dolomites and the predictive uses of different dolomite models.
  • Understand and identify the diverse origins of palaeokarstic macroporosity, associated risks and the different strategies for developing palaeokarstic reservoirs.

Training Course Content

  • A refresher on the basics of carbonate rock composition
  • Carbonate platform types and seismic expression
  • Plays, traps and reservoirs generalities
  • How carbonates change through time and how to predict likely reservoir-prone systems at different stratigraphic intervals
  • Source rocks, including intraplatformal basins
  • Isolated carbonate buildups de-risking targeting carbonate “bumps”
  • Platform margin plays: facies-controlled reservoirs and diagenetic controls (dolomite, fracturing, karst)
  • Platform interiors Late Paleozoic ice-house grainstone-to-build and fill systems, greenhouse systems and dolomite models
  • Carbonate sands tide, wave (barriers islands, infralittoral wedges) and internalites. Emphasizing how to determine possible sandbody geometries from regional to local data sets
  • Slope and basinal carbonate plays, including fan lobe systems and chalks
  • Dolomites especially HTDs and hydrothermal burial corrosion-related reservoirs
  • Paleokarst types, facies, identification, exploration strategies and risk

Course delivery details

  • 8am-11am CDT
  • Eight 3-hour interactive online sessions presented over 8 days (mornings in North America and afternoons in Europe). A digital manual and exercise materials will be distributed to participants before the course. Some reading and several exercises are to be completed by participants off-line.
