Gazprom begins Zapadno-Tarkosalinskoye liquids production
Gazprom Neft subsidiary Gazpromneft-Zapolyarye has begun liquid hydrocarbon production at Zapadno-Tarkosalinskoye field in the Purovsky district of the Yamalo-Nenets Autonomous Okrug of northwestern Russia. Commercial oil inflow from the first horizontal well stands at 380 tonnes/day, with potential to increase to 600 tonnes/day.
Gazpromneft-Zapolyarye will drill a further eight production wells in the course of developing Zapadno-Tarkosalinskoye. A mobile oil treatment unit and compressor station will be commissioned in 2020, and two cluster pads and a gas pipeline constructed by that time.
Zapadno-Tarkosalinskoye reserves in place are 40.6 million tonnes of oil, 444.5 billion cu m of gas, and 7.1 million tonnes of condensate, according to Gazprom. Development of the multilayer field with a complex geological structure will take geological faults and abnormally high reservoir pressure into account.
Gazpromneft-Zapolyarye began work at this field in 2018. Initial development involved the previously drilled exploratory well being de-mothballed to eliminate geological uncertainties and clarify reserve quality and volumes.
Gazprom Neft First Deputy Chief Executive Officer Vadim Yakovlev said about half of the company’s production will occur in the Yamalo-Nenets Autonomous Okrug “as soon as 2020.” Earlier in 2019 Gazprom and Royal Dutch Shell formed a joint venture for development of oil and gas fields in the region (OGJ Online, June 6, 2019).
