This paper justifies a new Achimov play development scheme for Urengoy field assuming the independents are engaged, given their complex resource base, both geologically and physically. Aiming to gain better development efficiency, a new upstream strategy was created, it is set to ensure the smallest hydrocarbons cross-flows between individual acreage and ultimate recovery factor. Common hydrocarbon reserve calculation procedures and a unified upstream development technology have passed government expert review for this purpose. When implemented, this strategy is set to become central for Yamal-Nenets social and economic development plan. Challenging resources in Achimov play are expected to add Gazprom Dobycha Urengoy more than 10% of Russian gas totals annually while maintaining flat production levels across maturing fields.
