It is known that field development and well operation requires regular high quality workovers to keep the existing well count in operable condition and to ensure a sufficient level of hydrocarbon production. Coiled tubing systems have been increasingly used for well killing, water shutoff, hydrate thawing, sand washing, well development, well stimulation and isolation, perforation jobs and fracturing operations.

Over the last few years, coiled tubing has become so popular that today there are more than 250 coiled tubing units in Russia and CIS which is about 12% of the global fleet. Besides, the scope and quantity of coiled tubing operations are also growing due to increasing scopes of horizontal drilling and multi-stage fracturing at Russian fields. This trend evidently has every reason to become permanent, as coiled tubing operations can improve well productivity, are less time-consuming and safer as compared to conventional workover units, most of which are morally and physically obsolete.

To optimize projects and to improve safety of high-tech coiled tubing operations, Weatherford, that has been successfully operating on the Russian oil service market for more than 10 years and has firsthand knowledge of all geological and technical problems of its customers, has developed a large variety of ready-made solutions and equipment for surface logging, workover and zonal stimulation including thru-tubing services.
