Properties and Characterization of Reservoir Fluids and Rocks Course
Introduction:
This course on the Properties and Characterization of Reservoir Fluids and Rocks equips students with the skills to accurately measure reservoir characteristics. It covers essential topics such as profiling the chemical composition of hydrocarbons, conducting laboratory PVT tests, and implementing quality control measures. Participants will gain the ability to appraise and make decisions regarding fluid and rock properties in geosciences.
The course also focuses on reservoir characterization, utilizing computer-based predictions of physical properties that integrate core analysis data from wireline logs and well data for specific calculations. By employing modern petrophysical diagnostics, students will gain precise estimations of reservoir rock properties and their interaction with interfacial density.
