This training course will highlight:

• Why we need a core and what is the maximum we can get from it
• How to have a good core and accurate analysis
• The application of core data and analysis onto reservoir rock evaluation
• How core can help explaining odd reservoir behavior and ambiguities
• All type of tools and lab analysis that we can have, what they provide per reservoir type
• All core interpreted data linked to environment of deposition, modeling and volumetric

Course Goals:

The main goals are to enrich the participant’s knowledge with in-depth core data, understand the coring procedure and its importance, maximize the usage of core analysis, learn the benefit of core interpreted data to geologists and engineers, create the best justification several reservoir behavior ambiguities and link all results in hand to future facies/zonation and modeling.

By the end of this training course, participants will hopefully learn to:

• Know the vital role of coring
• Understand the benefits of core analysis
• Maximize the usage of core data
• Understand and justify possible reservoir behavior ambiguities
• Apply interpreted core data to environment and facies

This training course suits all exploration and development staff and reservoir engineers, but it is mainly designed to for:

• Petrophysicists
• Geologists and Modeler
• Reservoir Engineers
• Geophysicists
