Characterization and Evaluation of Sandstone and Carbonate Reservoirs Course
Introduction:
Carbonate reservoirs exhibit significant heterogeneity across various scales, spanning from exploration to production and enhanced production phases. A comprehensive understanding of how primary depositional facies, diagenesis, and sequence stratigraphy influence pore development in carbonate rocks is crucial for accurate reservoir characterization. Additionally, recognizing how variations in pore architecture impact reservoir porosity and permeability characteristics is essential.
Course Objectives:
How To:
- Build on previous experience with carbonate systems to integrate various aspects of carbonate rocks (depositional environment, primary facies and mineralogy, high-resolution sequence stratigraphy, and various Petrophysical characteristics) for improved carbonate reservoir architecture and flow unit characterization
- Apply knowledge of Petrophysical, sedimentological petrologic tools to characterize and evaluate carbonate reservoirs
- Recognize and better understand well log responses in carbonate systems and to learn to utilize data from formation evaluation tools to determine reservoir quality (porosity, permeability, and lithology)
- Identify potential stratigraphic variations in carbonate pore architecture and its effect on permeability
- Better understand the relationship of primary depositional facies, sequence stratigraphic framework, and diagenetic history to pore architecture and reservoir quality
- Better understand fracturing in carbonates, relating fracture density, aperture, length to facies, lithology, and diagenesis
- Distinguish controls on carbonate reservoir heterogeneity, from sub-reservoir to reservoir scale
- Better understand carbonate reservoir heterogeneity and the value of 3D geostatistical model building to better manage the development of carbonate reservoirs
Who Should Attend?
Exploration and development geoscientists, Petrophysicists, reservoir engineers, geostatistical modelers, and research/development staff who want to gain fundamental insight into carbonate reservoir characterization through an integrated geological and petrophysical approach.
