In Tazovskoye oil, gas, condensate field “Gazprom Neft-Razvitie”, a subsidiary of “Gazprom Neft”, drilled high-tech wells with the record length of horizontal sections — more than 2 thousand meters.
Tazovskoye field belongs to the class of large fields with the low degree of study. Its initial geological reserves make 438 million tonnes of oil and 186 milliard cubic meters of free gas and gas-cap gas, as the press service of “Gazprom Neft” informs.
Within development of this asset “Gazprom Neft-Razvitie” built 13 high-tech wells last year. Among them there are two multilateral wells with two cased boreholes with the length of each horizontal section more than 2 thousand meters. The length of one of the horizontal boreholes made 2 thousand 263 meters, what became the record index for “Gazprom Neft”. In terms of complexity and uniqueness the high-tech wells of Tazovskoye field are equated to marine ones.
Use of a set of technological solutions that are non-typical for standard drilling, including a high- torque drilling tool, helped drillers to achieve the record results in difficult geological conditions. Since the beginning of development of this asset by “Gazpromneft-Razvitie” the accumulated production in Tazovskoye field has exceeded 100 thousand tonnes of oil.
This year full-scale development of Tazovskoye field begins. During a year it is planned to drill high-tech wells with horizontal sections with the length 2.5 thousand meters. In addition, it is planned to build three multilateral wells with three boreholes on the technology “fishbone”. The number of drilling rigs in the field will be increased up to four. In total, the project of development of Tazovskoye field supposes drilling of 132 oil and 10 gas wells. Input to operation and start of industrial development of the asset are scheduled for 2020. Peak production is forecasted in 2021 and will make about 2 million 100 thousand tonnes.
“Gazprom Neft” continues development of Tazovskoye field, which together with the North-Samburgskoye will become the basis of the new large-scale cluster of oil production being created by the company in Yamal. In this region the most high-tech wells are drilled in the perimeter of “Gazprom Neft”. In the process of development of thin oil rims we use modern materials and technologies that have already proved their high efficiency in practice, allowing us considerably to reduce the cycle of fulfillment of the project. The unique experience and competencies acquired within development of Tazovskoye field will be replicated later on other assets of the company with hard-to-recover reserves”, said Denis Sugaipov, the head of the directorate for large projects of “Gazprom Neft”, the director general of “Gazpromneft-Razvitie”.
