Gazprom Neft Starts Production at Tazovskoye Field in Okrug
Gazprom Neft has begun commercial hydrocarbon production at the Tazovskoye field in the north of the Yamalo-Nenets Autonomous Okrug. This is the first oil and gas field in Russia for which infrastructure has been put in place under the severe constrains of the COVID-19 pandemic. The field will become the centre of Gazprom Neft’s new production cluster, at which oil initially in place is estimated at 1.1 billion tonnes of oil. The launch ceremony for the Tazovskoye field took place on 16 June 2021
Gazprom Neft has commissioned an entire field-infrastructure complex at the field, commencing with development from the Tazovskoye-field oil-rim deposit, one of the most challenging assets in the Yamalo-Nenets Autonomous Okrug. Reserves initially in place are estimated at 419 million tonnes of oil and 225 billion cubic metres (bcm) of gas. Production infrastructure at the field includes oil and gas wells, a gas turbine power plant, oil and gas treatment facilities, oil and gas pipelines, a crude oil delivery and acceptance point (CODAP), and an employee housing complex. Annual production is expected to reach 1.7 million tonnes of oil and 8 bcm of gas.
In-field infrastructure construction has been conducted under the severe constraints arising from the COVID-19 pandemic,*** complicating the delivery of supplies as well as access-clearance for contractors and shift workers. Gazprom Neft’s anti-COVID barrier system, together with effective project management, has allowed it to overcome these challenges, however, and speed-up commissioning of the facility. Digital tools — including BIM modelling, and a “digital twin” of the field — were used in designing and building field facilities. Works oversight and approval was managed remotely using drones, together with airborne-laser scanning. Using a modular-block approach has reduced capital-construction volumes and halved lead-times in building field infrastructure.
The Tazovskoye oil and gas condensate field (OGCF) forms part of Gazprom Neft’s promising production cluster in the Nadym-Pur-Taz region in the north of the Yamalo-Nenets Autonomous Okrug. This project also includes the Meretoyakhinskoye and Severo-Samburgskoye fields, and two Zapadno-Yubileiny license blocks. Reserves initially in place across all of these assets, which include traditional reserves as well as hard-to-recover Achimovsky-strata reserves,stand at around 1.1 billion tonnes of oil and 492 bcm of gas. Geological prospecting is currently ongoing at these blocks, following which Gazprom Neft will formulate a development strategy for this cluster. Gazprom Neft subsidiary Meretoyakhaneftegaz will be the Operator on this new asset.
