Geology Designer

Static Geological Modelling

Build simulation-ready 3D geological models without upscaling. Geology Designer unites seismic, well and structural data in one static modelling workflow.

Build Simulation-Ready Geological Models - No Upscaling Required

tNavigator’s Geology Designer is static geological modelling software for building accurate, simulation-ready subsurface models. It brings seismic, well and geological data together in a single 3D environment, helping geoscientists model faster, interpret with more confidence and generate more reliable reservoir predictions.

Preserve Geological Detail, All the Way to Simulation

Take your models straight into simulation with no upscaling and no loss of geological detail. Geology Designer delivers best-in-class static modelling technology for constructing, quality-controlling and optimising 3D geocellular grids across even the most complex subsurface environments.


Unified Modelling Environment

Work within a single interface that brings together seismic, core, well logs, borehole data, structural maps and images – improving data consistency and geological confidence.

Workflow Automation with Python

Automate repetitive processes such as data import, model construction and analysis using flexible Python scripting, for greater efficiency and consistency across projects.

Seamless Subsurface Integration

Connect seismic interpretation, geological modelling and reservoir simulation within one workflow, enabling full traceability and uncertainty management across disciplines.


Geology Designer supports the full range of static modelling workflows:

  • 3D geocellular grid construction – build structured and unstructured grids for complex reservoirs.
  • Well log analysis & petrophysics – interpret and condition well data ready for modelling.
  • Seismic integration – bring seismic interpretation directly into the geological model.
  • Structural modelling – define faults, horizons and geological frameworks.
  • Fault & fracture modelling – capture structural complexity and its impact on reservoir behaviour.
  • Advanced property modelling – apply geostatistics and interpolation to porosity, permeability and facies.
  • Geomechanics integration – support coupled geomechanical workflows for stress and deformation analysis.
  • Quality control (QC) tools – validate every model before it reaches simulation.
  • Simulation-ready outputs – transfer models straight into reservoir simulation, with nothing lost in translation.

Fully integrated with the wider tNavigator platform

  • Seamlessly move between seismic, petrophysics, geological modelling and dynamic simulation
  • Maintain structural and property consistency across disciplines
  • Reduce manual data handling and rework, improving uncertainty understanding across domains

The result is one continuous workflow – from seismic interpretation through to production modelling.
