Reservoir Engineering - Integration of Wireline Formation Testing & Production Log Data Training

Current Course Schedule:

Objective:

This course has been developed for geologists, reservoir engineers and other petroleum technologists who are interested in the application of logging and distributed pressure measurements to enhance their understanding of the relationship between the geological model and the actual reservoir behavior.

Course Description:

Beginning with an introduction to the geological model of reservoir structures the course then demonstrates how formation tests and production log measurements can be used to improve understanding of the reservoir behavior, particularly in the case of layered and compartmentalized reservoirs. Field examples are used to illustrate how this integrated approach leads to improved reservoir description essential to the efficient management of the reservoir.
