High-tech wells

In September 2016, Messoyakhaneftegaz, a joint venture between Gazprom Neft and Rosneft, completed construction of horizontal wells with multilateral segments, known as fishbone wells. In these wells, there is one horizontal borehole with multiple ratholes. This well design helps significantly increase the coverage of oil-saturated areas of the reservoir compared to a conventional horizontal well. Gazpromneft NTC experts developed geomechanical models for the new well design before drilling began, and then supervised the well construction process on a 24/7 basis from Drilling Support Center.
