The article reviews the engineering, operational and logistical issues related to utilizing coiled tubing in Vankor oil field and the innovative solutions required to overcome these issues. The Vankorskoe field is located in the north of the Krasnoyarsk region close to the border with the Yamal-Nenets Autonomous District and at a  600-km distance from the Purneftegaz assets. The field was discovered in 1988. Proved oil reserves of the Vankorskoe field are 200 mln tons of oil barrels and it is expected to produce up to  25 mln tones per year of crude oil at its plateau. The Vankorskoe field will be one of the major sources of Rosneft’s production growth in the mid-term, and was launched in the second half of 2009. Upon completion of the East Siberia – Pacific ocean pipeline, Rosneft will be able to reach peak production at the field, which would allow accelerating exploration of the 14 licensed blocks adjacent to Vankorskoe. The field is drilled primarily with horizontal wells, 75% of which have smart completion. Oil production started at the Vankorskoe-9 well to ensure adequate fuel supplies to drilling crews.
