Recoverable reserves at Vostochno-Messoyakhskoye field up 32 percent

Year-end results for 2014 show recoverable C1 reserves of oil and gas condensate at the Vostochno-Messoyakhskoye field up by 49.7 million tonnes to 204 million tonnes (an increase of 32 percent). Total recoverable C1 and C2 reserves of oil and gas condensate at the Zapadno-Messoyakhskoye and Vostochno-Messoyakhskoye fields amount to approximately 480 million tonnes. The outcome of current estimations has been successfully confirmed by the State Commission on Mineral Reserves.

The transfer of a significant proportion of these reserves from category C2 (preliminary estimated or “inferred” reserves) to C1 (recoverable or “proved” reserves) followed geological prospecting undertaken at the Messoyakha fields througout 2013–14 — specifically, the construction of four exploration wells and the completion of 3D seismic over an area covering 490 km2, which also allowed the further refinement of the geological model used to identify the priority licence area for commercial development.

Plans for further geological prospecting in 2015 include the further refinement of geological modelling of the Vostochno-Messoyakhskoye field and the commencement of exploratory works at promising but, as yet, undeveloped sites throughout the Vostochno- and Zapadno-Messoyakhskoye fields. Full-scale development of the Messoyakha cluster will begin in 2016, once construction of the Zapolyarye-Purpe pipeline (which will transport crude from Russia’s northernmost fields) is complete.

The Messoyakha project comprises the Vostochno (Eastern) and Zapadno (Western) Messoyakhskoye acreages. Licenses for their development are held by Messoyakhaneftegaz, which is jointly controlled by Rosneft and Gazprom Neft. Gazprom Neft is the operator on the project.

The Messoyakha fields were first discovered in the 1980s, and are the northernmost of Russia’s onshore fields known to date. They are located in the Gydan Peninsula, in the Tazovsky district of the Yamalo-Nenets Autonomous Region, 340 kilometres north of Novy Urengoy, in Russia’s Arctic zone — a region of considerably underdeveloped infrastructure.

Pilot operations at the Vostochno-Messoyakhskoye field saw the first oil from this field produced in October 2012. Construction of a pressure pipeline from the Messoyakha fields to the Zapolyarye-Purpe trunk pipeline network was initiated in November 2014. The total length of the pipeline will run to approximately 100 kilometres, with a maximum discharge capacity of seven million tonnes per year.
