What Rock Flow Dynamics does

Rock Flow Dynamics is a privately held UK-incorporated software company that develops tNavigator, an integrated GPU-accelerated reservoir modelling and simulation platform for the energy and mining industries. Founded in 2005 and led by co-founder and CEO Vasilii Shelkov, the company combines geological modelling, reservoir simulation, geomechanics, fracture analysis, and surface network optimization into a single unified workflow spanning seismic interpretation to production systems. The platform is supported by a proprietary 1,000 sqm HPC data center in Belgrade, Serbia housing 30,000+ AMD EPYC cores and 172,000 NVIDIA CUDA cores, providing GPU-accelerated simulation that materially reduces run times versus traditional CPU-based reservoir simulators.

The company's product portfolio includes approximately 18 specialized modules covering seismic interpretation, geology and model design, mining, geosteering, PVT and well design, geomechanics, fracture simulation, and assisted history matching with uncertainty quantification. Recent releases have added an AI Assistant with natural language and voice interaction, Model Context Protocol integration, digital twin capabilities with real-time production data ingestion via Aveva PI, and integrated production modeling coupling reservoir behavior with surface networks. Cloud deployment is enabled through Microsoft Azure. The business operates an enterprise direct-sales GTM targeting oil and gas majors, NOCs, mining companies, and emerging new energy segments (CCS/CCUS, hydrogen storage, geothermal), with named customers including ADNOC, Wintershall Dea, Santos, Hungarian Gas Storage Ltd, and DBI Gruppe. Revenue derives from annual software licensing subscriptions, professional services (training, consultancy, model conversion), and cloud HPC services, with substantial academic licensing donations to institutions including UTM and West Virginia University indicating enterprise-grade per-seat pricing.

Core offering

Rock Flow Dynamics develops and sells tNavigator, an integrated GPU-accelerated reservoir modelling and simulation platform that combines geological modelling, geophysics, reservoir simulation, and surface network modelling into a single software environment. The platform is licensed primarily on an annual subscription basis to oil and gas operators, mining companies, and new energy (CCS/CCUS, geothermal, hydrogen storage) organizations, supplemented by professional services including training, consultancy, model conversion, and hardware optimization.

Product overview

Rock Flow Dynamics offers tNavigator, a unified all-in-one reservoir modelling and simulation platform that integrates every stage of the subsurface project lifecycle from seismic interpretation to surface network optimisation. The platform comprises a core simulation engine enhanced by approximately 18 specialized modules including Seismic, Geology Designer, Model Designer, Mining Designer, Geosteering, RP Designer, MBA, Reservoir Performance, Network Designer, PVT Designer, Well Designer, Geomechanics, Fracture Simulator, AHM & Uncertainty, and Adviser modules. The architecture enables seamless data flow between modules, allowing geoscientists and engineers to work from shared models and data. The platform supports advanced capabilities including GPU-accelerated simulation, AI-powered assistance with voice input, digital twin creation, integrated production modelling (IPM), and cloud deployment on Azure/AWS/Google Cloud. Rock Flow Dynamics also provides professional services including proof of concept studies, consultancy, model conversion, training, and hardware optimisation.

Scale indicators5 records

Recent moves9 records

Expansion highlights6 records

Broad incumbents

• Halliburton / Landmark: Halliburton's Landmark division offers the DecisionSpace Geosciences and simulation suite. It is a broad incumbent competitor to tNavigator with deep integration into Halliburton's drilling and completions services.
• SLB (formerly Schlumberger): SLB owns the Eclipse reservoir simulator and the broader Delfi digital E&P platform. It competes head-on with tNavigator at major operators but offers a much wider portfolio (drilling, completions, production) and far greater scale.
• Aspen Technology: AspenTech is an industrial simulation software leader that has expanded into energy and process optimization. While broader than pure reservoir simulation, it represents the same 'simulation-as-software' category and increasingly competes for digital-twin budgets at energy customers.
• Emerson (Paradigm / Roxar): Emerson's Paradigm and Roxar product lines include subsurface modelling and reservoir simulation tools. It is a broad E&P software incumbent competing across the same geoscience-to-simulation workflow that tNavigator targets.

Direct peers

• Computer Modelling Group: CMG is a publicly traded Canadian reservoir simulation software vendor (CMG STARS, IMEX, GEM). It is the closest direct competitor to tNavigator in commercial reservoir simulation, serving many of the same E&P operators with comparable physics-based simulation workflows.
• Beicip-Franlab (IFP Energies nouvelles): Beicip-Franlab develops PumaFlow and OpenFlow reservoir simulators and shares tNavigator's focus on advanced physics (compositional, fractured reservoirs). It is a direct peer serving NOCs, IOCs, and research institutions globally.

Emerging players

• LMKR: LMKR provides GeoGraphix and reservoir management software for upstream operators. It overlaps with tNavigator in geological modelling and subsurface data workflows, primarily targeting mid-sized and emerging-market operators.
• Teca S.r.l. Teca offers reservoir simulation and history-matching software used by European E&P operators and consultancies. It is a smaller, niche competitor with overlapping functionality to tNavigator's simulation and AHM modules.

Others

• ANSYS: ANSYS is a general-purpose engineering simulation platform used in adjacent workflows (multiphysics, CFD, structural). It is adjacent to tNavigator where reservoir problems intersect with broader physics simulation, and competes for engineering-software budgets.
• C3.ai: C3.ai provides enterprise AI application software with energy-sector deployments (including upstream). It is not a direct reservoir simulation competitor but addresses the same AI/digital-transformation budget at the same oil and gas customers.
