Core Analysis and Coring Methods
- Objectives of core analysis and coring methods
- Preliminary characterization
- Thin section petrography
- Fundamentals of Core-Log Integration
On the first day, participant will go over the objectives for the course and be given a general introduction. The day will continue on with topics such as upscaling, objectives for core analysis, and coring methods and fluids. Preliminary characterizations, including basics of core and log integration, and thin section petropgrahy will also be covered.
Geology, Pore Geometry and Storage Capacity
- Geology and pore geometry (Clastics and Carbonates)
- Core based total and effective porosity
- Core based permeability
Day two will cover geology and pore geometry and the basics of rock fluid interactions. Workshops, will include facies relationships, routine porosity-permeability relationships, core design and pore geometry discussions.
Petrophysical Rock Types and Introduction to Applied Capillary Pressure
- Petrophysical rock types using core analysis
- Pore throat characterization methods
- Pore throat systems combined with wettability and initial water saturation
- High pressure mercury injection porosimetry and practical interpretation methods
The third day will focus on the petrophysical significance of pore throat radius in determining petrophysical rock types using core analysis, as well as processing and interpreting high pressure mercury injection porosimetry capillary pressure curves. Participants will explore the relationships between pore throat radius, initial water saturation, and factors that control the initial saturation and distributions of reservoir fluids. At the end of the day participants will complete several applied workshops using Excel.
Reservoir Saturation – Water Saturation is Not an Accident
- Applied capillary pressure
- Core-log integration
- Predicting hydrocarbon contacts and free water level
- Overview of electrical rock properties
Day four will focus on reservoir saturations (hydrocarbon and water), using capillary pressure, electrical rock properties, and core-log integration. Participants will learn about how to apply capillary pressure to predict hydrocarbon contacts and the free water level. They will also learn about the basics of core-log integration based on Poe geometry, petrophysical rock types, and capillary pressure. Drainage and imbibition, SW distribution from various correlation, rock strength, static and sonic elastic moduli, and sanding will also be covered.
Relative Permeability, Wettability, and Saturation Height Modeling
- Relative permeability
- Wettability effects
- Applied Saturation Height Modelling
- Special Topics
The last day of this course will cover relative permeability, wettability, and the saturation height modelling. Participants will have a chance to learn about relative permeability, water-oil wettability effects, as well as gas-oil and gas-water wettability effects. The final workshop will include a well evaluation that includes facies, petrophysical rock types, and saturation height modelling.
