Applied Petrophysics and Well Log Interpretation


Geoscientists, petrophysicists, reservoir engineers and petroleum engineers who are involved in field development exploration, field development and integrated reservoir studies and are using logs, cores and test data to be able to characterize, model and manage their reservoirs.


The main targets of this training course are to create and then develop the understanding of the technique, needs and interpretation of logging, coring and test data. Each technique principles, response, measurements and analyses are treated separately. Then the participants will practice how to integrate these techniques together to come up with the best interpretation of our reservoirs. Examples from the Arabian Gulf will be discussed during the course (Thamama, Khuff, Arab and Mishrif reservoirs).This course will be conducted in a workshop environment. It contains 76 exercises that cement the idea of integrating geological, petrophysical and engineering data to better evaluation of our reservoirs.
