πŸ›οΈ Flagship Enterprise & Energy Platforms

Rust CPR-AMG SPE1 WASM Python CI

3D three-phase black-oil reservoir simulator built from first principles in Rust. It uses fully implicit Newton–Raphson with an exact Jacobian from automatic differentiation, handles saturated/undersaturated variable switching, and models Peaceman wells. Linear systems are solved with a true-IMPES CPR preconditioner (classical Ruge–StΓΌben AMG + ILU(0)). Results match the commercial ECLIPSE SPE1 reference to within 0.13% mean error, and 66,000-cell SPE10 subsets run 5Γ— faster than with ILU(0). GIL-free Python bindings drive ES-MDA history matching and CMA-ES/GA NPV well-placement optimisation. The same engine compiles to WebAssembly, with a Three.js 3D viewer.
