According to Rosneft’s press service, the company has released the second version of the RN-GEOSIM 2.0 software package, aimed at advancing geological modeling. The update introduces significant new capabilities, with the most notable being the generation of tectonically complex fault bed models. The release reflects Rosneft’s commitment to equipping its teams with tools that accelerate field planning, optimize drilling campaigns, and improve reservoir characterization.
Rosneft emphasizes that its IT solutions support a wide range of production tasks in geology, field design, development, and field operation. The software compares favorably with imported counterparts in speed, breadth of problem-solving capabilities, the use of modern algorithms, and a straightforward user interface that reduces training time for staff.
Within the Ufa Rosneft Scientific Institute, tectonic distortions are observed in roughly one of every three areas. Incorporating fault locations into modeling enhances the precision of locating and routing wells while also refining estimates of deposit reserves. This alignment of geological modeling with fault geometry helps minimize drilling risk and improves decision-making during license area evaluation.
RN-GEOSIM 2.0 now enables bed modeling with a complex fault network through new mathematical algorithms designed for three-dimensional paleogeographic reconstruction. This comprehensive approach restores both physical and environmental conditions of sedimentation, delivering a more accurate depiction of ancient depositional settings and their impact on today’s reservoirs.
The latest software version introduces auxiliary tools that streamline the creation of geological models. Built-in templates allow users to leverage lessons learned from prior projects, promote consistency across teams, and facilitate template sharing among colleagues. This feature supports rapid model generation while preserving methodological rigor.
In addition to enhanced 3D modeling, RN-GEOSIM 2.0 adds a reserve calculation option for 2D models. This capability enables quick assessments during the early stages of license area considerations, supporting faster go/no-go decisions and resource allocation. The 2D workflow is reported to cut evaluation time by up to fivefold compared with building a full 3D model, enabling efficient scoping of new prospects.
A concrete example cited by Rosneft shows that it took 15 working days to develop a comprehensive three-dimensional geological model for a single layer within the Tarasovskoye field. By contrast, a 2D model for the same layer was completed in just three days, illustrating the productivity gains achievable at early evaluation stages. The company highlights that RN-GEOSIM currently produces approximately 35% of its new models, with projections for 2024 showing a rise to around 75%. More than 400 specialists across Russian enterprises rely on the software in their day-to-day work, reflecting its growing adoption and impact on internal workflows.
