3.4. GREENFIELDS Development

Suzunskoye field



The Suzunskoye field is part of the Vankor cluster, including Rosneft’s largest field in the region. The field contains significant reserves currently estimated at almost 400 mm bbl of oil and almost 21 bcm of gas. The field is located across four license areas. Most reserves (91 % of recoverable oil and 98 % of gas reserves) are within the Suzunskoye license area (OJSC Suzun being the subsoil user) and some of them in the East Suzunskoye, West Suzunskoye, and South Suzunskoye license areas (Tagulskoye LLC being the subsoil user). The field is being prepared for the commissioning of the 1st start-up facilities scheduled for Q3 2016. The maximum oil production is expected to reach 4.5 mmt in 2017. The region has an oil and gas pipeline network, including the interfield Suzunskoye Field to Vankor Field pipeline. Further product transportation will be conducted via the Vankor-Purpe oil pipeline and Transneft trunk oil pipeline, East Siberia-Pacific, to provide access to the Asia-Pacific Region.

East Messoyakha License Area

The East Messoyakha license area is located in YNAO, northwards off 65 degrees north in the Tazovsk District of the Tyumen Oblast, about 190 km northwest of the Vankor area. The field development license is held by CJSC Messoyakhneftegaz owned in parity by Gazpromneft (50 %) and Rosneft (50 %). Gazpromneft-Razvitie LLC has been the operator since April 1, 2011. Large-scale development start is planned for Q4 2016. The current stage project objectives include the construction of the main infrastructure units and field start-up.

License agreements were updated and the license period was extended from 2020 to 2140. The four-year pilot production program, Phase 1, was completed with the final report defended in May 2015.

A total of 14 horizontal wells and five directionally drilled wells were drilled in 2015. The construction of the main infrastructure (CPF, pressure oil pipeline, pipeline commissioning station, living quarters and field support structures, and energy infrastructure) is in progress at the East Messoyakha field to ensure the start-up according to the schedule.

Exploration takes place in the West Messoyakha license area. Initial data was formed to build a detailed geological and hydrodynamic model for the pay zones.

Labaganskoye field

Commercial oil production was started at labaganskoye field in q3, 2015

RN-Severnaya Neft LLC started commercial oil production at the Labaganskoye field in Q3 2015. While preparing for this stage, seismic surveys were completed using 3D CDP seismic reflection method, exploration wells were drilled, and a large work scope was performed to prepare to production drilling, including the survey of oil and reservoir properties for the reservoirs with commercial oil inflows.

The Labaganskoye infrastructure development program involved the construction of a 101.5 km oil pipeline from Labaganskaya OTU to Nyadeyuskaya BS, installation of the first separation stage, furnace area, temporary booster station, and fuel tankage, and construction of an energy center. Timely start-up of these facilities will ensure uninterrupted oil transportation to RN-Severnaya Neft treatment facilities. Furthermore, four cluster pads, an area for an oil treatment unit and field support facilities were backfilled. The total preparatory scope exceeded one million cubic meters of soil.

21 wells were launched at the field in 2015 with a total average daily production of over
1.6 th. tpd. The Labaganskoye field is a part of the Sorokin Swell. Eleven layers in the field are considered oil-bearing. Production in 2016 is expected to approximate 1 mmtoe as of the end of 2015, the field reserves according to PRMS classification are estimated as 241 mm boe.

Naulskoye field

Commercial production at the field is expected to start in 2016. Seven wells are planned to be built with an average start-up flow rate at 90.3 tpd and field equipment and infrastructure are planned for construction. As of the end of 2015, PRMS-classified field reserves are estimated
as 239 mm boe. New reserves and expansion of resources are the strategic objectives of RN-Severnaya Neft LLC. New field development will create new jobs which will boost the social and economic situation in the region.
