The company proceeded to the full-scale development of the Zima project in the Khanty-Mansi Autonomous Okrug–Yugra. Gas production across the Group was up 5.5% to 43.08 bcm. The new fields operated by Gazpromneft-Zapolyarye (Zapadno-Tarkosalinskoye and Pestsovoye fields), Meretoyakhaneftegaz (Tazovskoye field) posted the highest production increases in 2020 and Gazpromneft-Khantos (Alexander Zhagrin field). 1 — Including gas condensate. 2 — Consolidated companies. 3 — The company’s share in production. 70 Annual Report 2020 Company Asset of the Future profile The Asset of the Future Programme seeks to deliver an integrated transformation of the business model for the Gazprom Neft Upstream Division by optimising business processes, enabling digital transformation, as well as developing cross- functional capabilities and new ways of working for our employees. Strategic To ensure cross-functional and integrated changes, the Programme uses our product-based approach, adapted for the oil report business. As a combination of new processes, capabilities and technologies, the product not only forms a cross-functional business-management tool that focuses the attention of management, but it also enables the company to bring about a multi-faced change-and-run transformation. Programme highlights in 2020 Performance In 2020, the company integrated all processes into six dedicated business products across the entire value chain: review from finding new development opportunities to exporting products at custody transfer points. Rolling out a cross- functional business model for each business product prompted operations teams at subsidiaries to progressively develop new capabilities and refine “one team one business goal” teamwork. Product teams launched more than 25 pilots to address the key business challenges facing the company’s upstream enterprises. A rapidly-built management system kept a normal operating rhythm even in a remote-working environment, and covered over 700 employees from dozens of the company’s divisions. Product-based interaction and decision-making Technological development have become routine processes at both the Gazprom Neft Corporate Centre and subsidiaries. As early as 2019, the pilot asset delivered ₽1.2 billion in business impact; but in 2020, the programme-associated benefits topped ₽3.6 billion, driving positive cash flow and proving the potential to deliver a ₽100 billion impact up to 2030. A new single operating model, deploying end-to-end processes across all management levels, and rapidly rolling Governance out solutions and best practices throughout product teams, – from new ways of working to innovative Industry 4.0 system technologies – makes sure this transformation is sweeping and effective. The Production Directorate is completely switching to the new product-based model in 2021. The programme will pursue the following key objectives: – implement a product-based approach across the entire value chain, and deploy the operating model 2.0 at the asset level in 10 subsidiaries; – interface products with the Integrated Operations Centre and scale these interfaces according to potential; Sustainable – implement a single digital landscape across all business products and management levels: from asset development to the Gazprom Neft Corporate Centre; – introduce uniform company-wide principles and interaction requirements for all Ecosystem participants.
