Production drilling starts at Gazprom Neft Vostochno-Messoyakhskoye field

Full-scale production drilling has commenced at the Gazprom Neft Vostochno-Messoyakhskoye field (part of the Messoyakha group, the northernmost onshore fields currently under development in Russia).

Twenty one wells on six cluster pads will be built by the end of the year, including three process wells and one gas well, supporting a gas turbine power plant (GTPP). A total six drilling rigs will be deployed on the Messoykha project by the end of 2015, four of which will host production wells and two prospecting wells. The total number of drilling teams is expected to reach 10 by 2016.

The drilling programme will make full use of cutting-edge techniques and materials. The development plan for the Messoyakha project envisages, in particular, the drilling of high-technology wells with horizontal sections running to more than 1,000 metres in length. In addition to this, new drilling technology will be utilised, protecting equipment from any soil ingress. The use of special Arctic and flexible cements in well cementing also improves performance under conditions of long-standing permafrost.

The Messoyakhskoye field

Formation samples are expected to be taken from the wells during drilling, allowing the timely collation of information on the structure of geological strata and the selection of the optimum well construction in view of this.

A four-year programme of pilot works at the Vostochno-Messoyakhskoye field was completed in spring 2015. Installation of production infrastructure has been actively pursued since 2014, in preparation for the planned commissioning of the field in late 2016. Construction of an oil pipeline connecting the field to the Zapolyarye-Purpe main trunk pipeline is currently ongoing, as well as construction of a 84 MW gas-turbine power plant, central oil collection point, and other facilities.

Notes for editors

The Messoyakha group of fields include the Vostochno (Eastern) and Zapadno (Western) Messoyakhskoye acreages — the northernmost onshore oilfields in Russia. Licences for prospecting and development at both fields are held by Messoyakhaneftegaz, jointly owned by Rosneft and JSC Gazprom Neft. Gazprom Neft is operator on the project.

The fields, which were first discovered in the 1980s, are located in the Gydan Peninsula, in the Tazovsky district of the Yamalo-Nenets Autonomous Okrug, 340 kilometres north of Novy Urengoy, in Russia’s Arctic zone — a region of considerably underdeveloped infrastructure. Proven C1 and C2 reserves indicate 480 million tonnes of oil and gas condensate, as well as more than 180 cubic metres of natural and associated gas. Pilot operations at Vostochno-Messoyakhskoye saw the first oil from this field produced in October 2012.

Within Gazprom Neft preparations for the development of the Messoyakhskoye group are being managed by the Messoyakha branch of Gazpromneft Razvitiye, responsible for managing the parent company’s most significant projects.

The Messoyakha fields include the Vostochno (Eastern) and Zapadno (Western) Messoyakhskoye acreages.
