Gazprom Neft has begun testing and adjustment on start-up facilities of a gas treatment unit, together with the gas injection system, increasing electricity supply from a gas turbine power plant (GTPP) to production facilities at the Novoportovskoye field (Yamalsky District, Yamalo-Nenetsk Autonomous Okrug).
The gas treatment unit is designed to process associated petroleum gas (APG), with its subsequent reinjection into subterranean strata. At full capacity the facility will utilise more than 95 percent of APG, with positive impacts for the Arctic ecosystem, as well as increasing production volumes at Novoportovskoye field and extending the useful life of the wells.
The process flow for gas injection currently includes the gas treatment unit, comprising four 32 MW gas-compressor units, two gas disposal well clusters, and an extensive gas pipeline network. The complex also includes a dehydration unit and an automated control room allowing round-the-clock monitoring of the equipment’s status and operating conditions.
The processed APG from the facility will also be used as fuel for the GTPP — the largest in the Yamal Peninsula, with a design capacity of 96 MW (with scope for this to increase to 144 MW). Once the gas treatment unit is brought into full operation, the GTPP will supply electricity for social (communal) and domestic needs, as well as to production facilities at the Novoportovskoye field.
Vadim Yakovlev, Deputy Chairman of the Management Board and First Deputy CEO, Gazprom Neft, commented: “The gas infrastructure at the Novoportovskoye field is a project unique to the Russian energy industry. Thanks to the holistic solution being implemented by Gazprom Neft on the Yamal Peninsula, we have the opportunity to make sure all hydrocarbons produced here are put to constructive use. Building the most complex production facility in the Arctic confirms our company’s considerable skills and competencies not just in implementing projects under harsh climatic conditions, but also in the most remote and isolated locations.”
