Introduction:
Course Objectives:
How To:
- Identify clastic and carbonate rock types based on productivity differences
- Determine the key reservoir rock parameters needed for a more accurate reservoir evaluation
- Use cuttings, sidewall cores, and cores to determine reservoir parameters
- Design an integrated interpretation
- Calculate VCLAY
- Calculate porosity using porosity logs in complex lithology
- Determine what percentage of porosity contributes to the production
- Calculate SW using different methods
- Determine pay and pay classes
- Tie rock and well log information to production performance
Who Should Attend?
Petrophysicists, petroleum reservoir engineers, geologists, and geophysicists who have a basic understanding of Petrophysics, geology, and engineering and need a more advanced understanding of how to integrate the different data sets together to more completely understand reservoir performance. It is recommended that participants have a basic knowledge of logging fundamentals. The basics of logging will be reviewed in the class.
