New technology of building of multilateral wells was used successfully in Novoportovskoye field. Its use allowed the company “Gazpromneft-Yamal”, which develops the field, to increase oil recovery of a formation and considerably to increase effectiveness of development of the field.
The technology of drilling being in use foresees fastening of a metal pipe in each horizontal borehole of the well in order to prevent from rock sloughing and loss of the drilled borehole in the process of its exploitation. Experts of the scientific and technical center of “Gazprom Neft” together with specialists of “Gazpromneft-Yamal” fulfilled elaboration of design and round-the-clock accompanying of drilling.
The length of each borehole of the first bilateral well constructed in the field makes 1000 meters; its initial production rate was registered on the level more than 400 tonnes per day. Now 5 such wells operate in Novoportovskoye field. At that, each new well is drilled faster than previous one, what allow decreasing its costs considerably, as the press-service of “Gazprom Neft” informs. In the result, the specialists managed to reach the company’s record speed of drilling of multilateral wells – 5.87 days per one thousand meters, what is compared with the best results on drilling of single-bore horizontal wells.
Introduction of new technologies of drilling is a part of the technological strategy of “Gazprom Neft”. The document systematizes search of innovative decisions in the company to create points of long-term development. Projects of high-technological drilling and increase in oil recovery being fulfilled in fields of the company already today allow involving reserves, which earlier were not considered promising, into profitable development, as the first deputy director general of “Gazprom Neft” Vadim Yakovlev notes.
