Well Stimulation Technologies (PRE34)


    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. Formation damage and its effect on well performance is presented and discussed. 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. The main stimulation techniques are presented and their advantages and disadvantages are discussed. Candidate selection of various techniques is presented.

    Course Level: Foundation
    Duration: 4 days
    Instructor: Catalin Teodoriu
