Applied Microfacies Analysis
This training covers applied microfacies analysis of carbonate rocks. It works through carbonate components and their recognition, texture classification, microfacies types and their definition, depositional environment interpretation, platform models and facies belts, diagenetic overprint and its recognition, microfacies and reservoir quality, logging microfacies through a core, correlation using microfacies and the application of microfacies analysis to reservoir studies.
Description
Microfacies analysis is the interpretation of carbonate depositional environment from the components, texture and fabric visible in thin section. In carbonate rocks it is the primary environmental tool, because the grains are biological and their composition records the depositional setting far more precisely than clastic grain composition does. It also establishes the facies framework on which carbonate reservoir quality prediction depends.
This training covers microfacies analysis as applied to reservoirs. Carbonate components and their recognition are established first, covering skeletal and non-skeletal grains and their environmental significance. Texture classification follows, covering the Dunham and Embry-Klovan schemes and their application. Microfacies types and their definition are then developed, covering the standard schemes and the construction of local schemes. Depositional environment interpretation follows. Platform models and facies belts are then addressed. Diagenetic overprint and its recognition follow, since diagenesis obscures depositional texture in carbonates more than in clastics. Microfacies and reservoir quality are then developed. Logging microfacies through a core follows. Correlation using microfacies is addressed. The training closes with application to reservoir studies.
Carbonate grains are fossils and they record the environment directly. A grainstone of ooids formed in agitated shallow water; one of planktonic foraminifera accumulated in deep water; a packstone of green algae indicates the photic zone in a restricted lagoon; rudist fragments indicate a particular interval and setting. The grain assemblage therefore constrains water depth, energy, salinity and circulation far more tightly than a clastic grain composition can, which is why microfacies analysis works.
Texture records energy and the classification schemes capture it. The Dunham scheme separates mud-supported from grain-supported fabrics and records the presence of carbonate mud, which is the energy indicator: mudstone and wackestone indicate low energy, packstone and grainstone progressively higher. Combined with the grain assemblage this produces an environmental interpretation. The Embry-Klovan extension handles reef and boundstone fabrics the original scheme does not.
Diagenesis obscures the depositional texture and may replace it entirely. Carbonate rocks are chemically reactive and pervasive recrystallisation, dolomitisation and dissolution can destroy the original grains and fabric, leaving a rock whose depositional origin is difficult or impossible to determine. Recognising the degree of overprint, and identifying the residual evidence of the original texture where it survives, is a central skill, and intervals where the overprint is complete should be recorded as indeterminate rather than guessed.
Finally, microfacies predicts carbonate reservoir quality better than texture alone. A grainstone may be an excellent reservoir or tight depending on cementation; a mudstone may have no porosity or may have substantial microporosity. The combination of the depositional microfacies and the diagenetic history determines the pore system, and microfacies analysis supplies the first half of that. Mapping microfacies therefore provides the framework within which the diagenetic variation is understood, which is how carbonate reservoir quality prediction is built.
By the end of this training, participants will be able to:
- Recognise carbonate components and interpret their environmental significance
- Apply Dunham and Embry-Klovan texture classifications
- Define and apply microfacies schemes
- Interpret depositional environment from microfacies
- Apply carbonate platform models and facies belt concepts
- Recognise diagenetic overprint and its degree
- Identify residual depositional evidence in altered rock
- Relate microfacies to reservoir quality
- Log microfacies systematically through a core
- Apply microfacies analysis to correlation and reservoir studies
The training is microscope work throughout on carbonate thin sections from several platform settings. Participants identify components, classify texture, define microfacies and interpret environments. Microfacies logs are built through cored intervals and compared against the log response and the measured reservoir properties. Heavily altered intervals are examined to establish what can and cannot be determined.
