Applied Carbonate Diagenesis with Emphasis on Sequence Stratigraphy and Impact on Reservoir Quality Evolution Course
Introduction:
This course combines, scientific materials, and relevant work experience, of lecturing and courses presented to the industry by the instructor.
It is useful not only to CAMS, operational, geomodelers or experienced oil industry geoscientists, but also to non-specialists dealing with carbonates, either for geological or engineering purposes.
This course of applied diagenesis methods is easier to follow than many well-illustrated texts that confuse the non - specialist. The slides are well-organized, abundant diagrams and a large number of photomicrographs for better understanding.
Course Objectives:
- Introduction to Carbonate Diagenesis and Impact on Reservoir Properties
- Marine Cement of Carbonate Reservoirs and Examples of Diagenetic Overprint
- Meteoric Diagenesis and its applications in Sequence Stratigraphy and
- Reservoir Development (Vadose zone and Phreatic Zone)
- Burial Diagenesis, Cement Morphology , Examples and applications
- Dolomite and Saddle Dolomite, Possible Causes and Nature of Baroque Dolomite
- Dolomitization and De Dolomitization, Examples and Interpretation
- Impact of Diagenesis on Reservoir Properties Evolution and Sequence Boundaries
- Paragenetic Sequence, examples and impact in Reservoir Properties
- Detailed Geological Analysis and Analytical Techniques CL, SEM, Isotopes
- Applications of Diagenesis in 3D Reservoir Modeling (Petrel)
Who Should Attend?
Geologists, geophysicists, engineers, engineering trainees, technical managers, technical assistants, technicians, chemists, physicists, technical supervisors, service company personnel, sales representatives, data processing personnel, and support staff working with reservoir definition, development and production.
