TECHNOLOGICAL SOLUTIONS FOR DRILLING USING FLEXIBLE TUBING – UP-TO-DATE WORLD EXPERIENCE AND PROSPECTS FOR RUSSIA

The article presents an analytical review of modern technologies for using flexible tubing to perform complex technological operations aimed at increasing oil recovery, exploration and repair of wells, and construction of lateral and horizontal wellbores. The authors have been most interested in the technology of underbalanced coiled tubing drilling, since it has the potential to increase oil production while maintaining or minimizing drilling costs without drilling complications while ensuring operational safety.The experience of a foreign company in coiled tubing drilling is reviewed, positive results and growth points are highlighted. Solutions for the implementation of coiled tubing drilling in Russian conditions are proposed to reduce the costs of constructing horizontal wells and additional hydrocarbon production during the drilling process. Preparatory work is underway to conduct pilot-industrial research of the proposed technology.
