Prospects for coiled tubing development in Russia

Abstract

At present time, coiled tubing units perform almost all types of intervention operations. These units are fully automated, and in fact are pilot models of future drilling and workover rigs. Unfortunately, reserves structure, depth and accessibility are becoming more complex each year so that standard operations no longer address challenges we face today. Drilling of more complex wells require development and application of non-standard equipment. This includes multistage fracturing completion systems and CT as the main tool that meets modern requirements. Nowdays, there is a clear tendency for the increase in CT length and diameter. CT wall thickness has also been changed. Service companies start to apply tapered CT strings optimized for certain well conditions. Equipment, which is discussed in the article has not yet been used in the fields of Gazprom Neft. Therefore, it is very important to approach the problem of the correct selection of all key aspects both from a technical and technological point of view in advance.
