Reservoir Quality and Rock Type Analyses in Carbonate Rocks (One Day Course)

This course discusses the pore system evolution in carbonate rocks as a result of the complex interaction between diagenesis and facies. An intricate path that leads to the prediction of large-scale reservoir potential evaluation.

Course summary and outline

This course is focused on the analysis of depositional textures and their subsequent diagenetic modifications as the main control on the pore system heterogeneity and complexity.  The intricate inter-relationship of the depositional and burial history can be unravelled to allow prediction of reservoir facies and reconstruction of three-dimensional reservoir models. Carbonate rock typing provides a tool for propagating reservoir properties in the static/geological models based on an exhaustive calibration of conventional and computed logs with rock data at core, plug, thin-section and pore scales. The course demonstrates the value of understanding pore system evolution as a part of large-scale volumetric assessments and development of carbonate reservoirs.
The workshop is organised into three sessions:

Part A: Reservoir quality analysis - what it is and how to approach it
• Definition of reservoir quality
• Introduction to carbonate rock pore systems: a heterogeneous and complex world
• Commonly used analytical techniques to measure pore volume and connectivity

Part B: Controls on reservoir quality - from deposition to diagenesis
• Depositional controls
- Texture: allochems vs matrix
- Skeletal and non-skeletal allochems: how they affect pore volume and distribution
- Micritic matrix: a small world with a big impact
- Bioturbation
- Clay content
• Diagenetic controls
- Dissolution: early vs late
- Cementation: pore-lining vs pore-filling
- Dolomitisation: replacive vs cementing
- Compaction
• Tectonic controls
- Fracturing

Part C: Rock types and their importance on the large-scale modelling
• How to display porosity/permeability data
• How to define rock types
• Importance of rock typing in reservoir modelling

Note: each section will be accompanied by examples from case studies.

Course Information

Who Should Attend?
The course is targeted at petroleum geologists, geoscientists, petrophysicists and engineers involved in exploration and production of carbonate plays.  Previous knowledge in carbonate sedimentology is not necessarily required.

Instructor
Matthieu Deville de Periere - Matthieu is a senior carbonate geologist based in Abu Dhabi with an interest in carbonate petrography and sedimentology. With established experience in the Middle East, Matthieu is currently working on single-well and multiwell reservoir quality evaluation studies dealing with carbonate plays of the Arab Gulf.  These projects cover a wide range of depositional environments from shallow to deeper water carbonates.
