The comparison.

A comparison is meaningful when its case, reference and limitations are visible.

Research snapshot

SPE9 against OPM Flow

Day 10, field-level production rates. Relative difference is calculated against the OPM reference.

This snapshot is not qualified. Source, geometry, PVT and time-step convergence still require audit.
