A well intervention is any operation carried out on oil or gas well during its productive life that alters the state of the well, provides well diagnostics, or manages the production of the well.


Primarily in this training course, we are concerned with problems associated with the completion string. Problems associated with the reservoir can be investigated and evaluated using production logging and well test techniques. In general, problems associated with the completion string can be classified into problems which arise in the tubing bore and which can be corrected through tubing operations and problems which necessitate the retrieval of the completion string from the well.


This course will contain in-depth information on the impact of workovers and completion design in maximizing field production and increasing recoverable reserves. It also emphasizes the importance of well interventions methods (slick-line, Electrical line and Coiled tubing) during life time of the well to keep well productivity under optimum conditions.
