Oil & Gas · Subsurface

Faulted, folded, layered reservoirs — meshed by construction.

Conforming Voronoi (PEBI) grids for reservoir simulation and CO₂ storage, honoring every fault and horizon exactly.

AutoMesh-Geo · Oil & Gas
Conforming polyhedral mesh

The subsurface doesn't simplify itself: faults, unconformities, steep dips and pinch-outs defeat ordinary meshers, and reservoir solvers demand true Voronoi (PEBI) grids that honor the geology. AutoMesh-Geo builds them straight from your structural model — so reservoir characterization, flow simulation and CO₂-storage studies start from geometry you can trust.

The bottleneck

Where meshing costs you the most

Faults and pinch-outs break the grid

Complex 3D geology — faults, unconformities, steep dips, pinch-outs — is exactly where grid-based and ordinary meshers introduce non-conforming cells and leaks.

Solvers demand true Voronoi (PEBI) grids

Reservoir and CO₂-storage solvers want perpendicular-bisector (PEBI/Voronoi) grids that honor faults; building them by hand is slow and fragile.

Trapping and flow physics rest on the mesh

If the grid doesn't conform to faults and seals, the migration, trapping and flow paths you simulate aren't the ones in the ground.

How AutoMesh-Geo helps

Meshing that keeps up with your design loop.

AutoMesh-Geo is built on VoroCrust, the provably-conforming Voronoi meshing method from Dr. Mohamed Ebeida and colleagues (ACM Transactions on Graphics, 2020). Provable conformity to faults and horizons is exactly what subsurface models need to trust the flow and trapping physics.

Conforms to faults & horizons

Every fault plane, unconformity and stratigraphic layer is honored as a hard constraint, so the grid never drifts from the interpreted geology.

True Voronoi / PEBI grids

Provably-conforming Voronoi cells are exactly the perpendicular-bisector grids reservoir and subsurface solvers are built for.

From structural model to solve

Go from a faulted, layered geologic model to a solver-ready grid without weeks of manual grid-building.

Use cases

Grounded in published research
“Most meshers build a grid, then fight to repair it. We generate a mesh that’s correct by construction — the guarantee comes from the mathematics, not from cleanup.”

FAQ

Common questions

Do you produce PEBI / Voronoi grids for reservoir solvers?

Yes — conforming Voronoi (PEBI) cells are the native output, honoring faults and horizons by construction. Tell us your reservoir or subsurface solver and we'll confirm the export on a demo.

Can it handle faults, pinch-outs and complex structure?

Feature conformity is the whole point: faults, unconformities and pinch-outs are hard constraints, not obstacles the mesher smears over. Send a structural model and we'll show you.

Is it suitable for CO₂ storage studies?

Yes — faulted, layered storage geology is a core target, and a grid that conforms to faults and seals is what makes trapping and migration results trustworthy. Book a walkthrough on your formation.
