    Introduction to Rigless Well Intervention

    This course is at intermediate level an overall revision of all technologies used in rigless well interventions, as well as the major concerns in the discipline.

    The course starts with a revision of well integrity and the formulation and placement of remedial cementing; describes methods to calculate frac gradient; discusses perforating methods; re-visits matrix treatments in sandstones and carbonates, presenting perforating as a valuable alternative; overviews fracturing and sand control management and sand cleanout; presents calculation methods for nitrogen applications; discusses applications for coiled tubing interventions and for fishing; and, overviews artificial lift methods.
