Creating 3D geological model of the Bazhenov formation of the northeastern slope of the Krasnoleninsky arch
Abstract
The Bazhenov formation is one of the most promising objects for maintenance and increase of oil production in Russian today. Great attention is paid to instruments of modeling that allow localizing sweet spots for production. The article presents approaches of creating 3D geological model of the Bazhenov formation. Modeling is based on a large amount of factual material, including laboratory studies of core samples, well logs and seismic surveys. Particular attention is paid to the geological concept, which takes a leading role in the modeling process. There are two objects which conclude the largest amount of mobile oil. One of them is represented by siliceous rocks with a primary organic structure. The other one is siliceous-carbonate and phosphate concretions. Areal extent of siliceous rocks is controlled by sediment factors. Siliceous-carbonate and phosphate concretions confined to fault zones. Creating 3D geological model of the Bazhenov formation was made possible by analyzing the vertical and lateral inhomogeneity of unconventional reservoir.
