3D Modeling Boosts Oil Extraction Efficiency at Russian Arctic Field

Russian scientists are using a detailed digital model of the Sugmut oil field to optimize drilling strategy and reduce the number of unprofitable wells.

Researchers in Russia have built a three-dimensional digital model of the Sugmut oil field in the Yamal-Nenets Autonomous Okrug. The model is expected to significantly enhance extraction efficiency and cut down on unnecessary drilling.

The effort was led by scientists from the Institute of Oil and Gas Geology and Geophysics of the Siberian Branch of the Russian Academy of Sciences, in collaboration with Tyumen Industrial University and several industry partners. They combined 3D seismic survey data with drilling operation logs to construct a detailed geological model that revealed zones with low production potential.

As a result, the original plan to drill 195 wells was scaled back by eliminating 43 and identifying another 32 for potential cancellation. This approach is grounded in precise calculations of economic flow rate thresholds — the minimum daily output needed to justify a well’s operation. For the Sugmut field, that threshold is 9 tons of oil per day.

The model also guided the selection of well types. Based on predicted reservoir productivity, researchers recommended horizontal and gently sloping drilling paths. Tests confirmed the effectiveness of this strategy.

The project is being hailed as a successful case of digital technology integration in Russia’s oil and gas sector.
