Designed for:

This course is designed for engineers working on naturally fractured gas-condensate reservoir.

Course Overview:

This is an in-depth course that is designed to provide the participants with a solid understanding of the depletion and development performance of Naturally Fractured Gas Condensate Reservoirs. Understand gas-condensate reservoirs and the impact of their PVT data on the performance of NFR is the key for studying and optimizing field development to maximize field recovery from these complex types of reservoirs.
