It is estimated that more than 60% of the world’s oil and 40% of the world’s gas reserved are held in carbonate reservoir. Carbonate reservoirs exhibits varying properties making it difficult to be characterized. A focused approach is needed to better understand the heterogeneous nature of rock containing fluids and the flow properties within the porous and often fractured formation. This involves detailed understanding of the fluid saturation, pore-size distribution, permeability, rock texture, reservoir rock type and natural fracture systems at different scales.

During this course, the concepts of petrophysical rock properties such as porosity and permeability and mineralogy in carbonate reservoirs will be covered. The relationships between these parameters and in situ fluid saturation will be discussed. The physics of well logging tools to methods of interpretation of these parameters will be applied. The understanding of acceptable well log quality and the recognition of good well log data will be addressed. This course is prepared to provide the interpretation, concepts and techniques for carbonate reservoirs on which to develop the petrophysical knowledge and capabilities necessary for geologists, geophysicist, engineers and Petrophysicists. The understanding of acceptable well log quality on tool measurements, data handling and the recognition of good well log data will be addressed.

By the end of this course delegates will be able to:

• Understand concepts of petrophysical rock properties in carbonate reservoirs
• Acquire knowledge on lithofacies in carbonates and porosity determination
• Discussion on fractures, vugs and Bitumen detection in carbonates
• Determine and understand core and core analysis
• Learn and practice on interpretation concepts
• Understand saturation using Archie’s equation
• Identify petrophysical parameters evaluation from core and log data
• Gain knowledge on log quality control on tool measurements (log readings) and data handling
• Be more able to apply knowledge using carbonate reservoir examples
• Learn quick look interpretation using advanced methods and cross-plots
