Well Stimulation Technologies (PRE15)


    This course covers the main aspects of Well Stimulation whose main objective is to repair formation damage in order to restore/increase production.
    It starts by presenting the basic concepts for stimulation job design, execution and follow up. Discussion is carried out on formation damage and its effect on well performance and planning of acid stimulation treatments. Focus is given to the main causes of formation damage (damage during drilling, cementing, perforating, producing and working over wells) and how these may be identified.

    Course Level: Skill
    Instructor: Antonio Abreu
