Gazpromneft-Noyabrskneftegaz embarks on a major study of Achimovsky strata in the Yamalo-Nenets Autonomous Okrug

Gazpromneft-Noyabrskneftegaz is embarking on a major geological prospecting project to investigate productive horizons in Achimovsky strata using cutting-edge technologies. Industry specialists believe this will allow the company to significantly increase its resources base in terms of existing assets, and put in place the prerequisites for acquiring new ones. Investment is expected to reach RUB3.7 billion. The project is being implemented together with Gazpromneft-GEO and the Gazprom Neft Science and Technology Centre.

The portfolio includes 20 license blocks, covering a total area of 21,000 square kilometres. A range of geological exploration works are to be undertaken at the four most promising of these — the Novoromanovsky, Sugmutsky, Sutorminsky and Severo-Yangtinsky blocks. Processing and interpretation of 3D seismic data, core surveys, testing of existing wells and drilling of several new ones, and the building of a local geological and petrophysical model to confirm resource potential, are all due to be completed by 2023. The results of investigations across these four blocks will make it possible to assess the potential for developing the remaining 16.

“The changing nature of the reserves we are working with in Western Siberia these days demands a completely new approach — and demands finding breakthrough technologies to develop these profitably. Achimovsky deposits have colossal potential — estimated by various industry experts at 60 billion tonnes of oil equivalent (btoe). Gazprom Neft is, already, the first industry player to create a conceptual geological model of Achimovsky strata, which cover an area of 1.5 million square kilometres. Bringing these resources into development is one of the company’s key strategic objectives. We’re talking, among other things, about Gazpromneft-Noyabrskneftegaz’s mature assets in the south of the Yamalo-Nenets Autonomous Okrug — these fields could get a new lease of life, and the experience gained here will be of benefit to Russia’s entire oil and gas industry.”
