Enhanced Oil Recovery (EOR) Modeling L1-462
Unclaimed Principle — open for contribution
This Principle is declared in the catalog but has no reference solver, no pinned dataset, and is not registered on-chain. There is no reward pool. Submitting a cert against this Principle today will record the cert for reproducibility but pay zero PWM.
To claim it as a Bounty #7 contribution: open a PR adding (1) a reference solver, (2) ≥1 dataset pinned to IPFS, (3) updates to the L3 manifest with dataset CIDs. After verifier-agent triple-review, the founders' 3-of-5 multisig signs PWMRegistry.register() and the Principle becomes mineable.
Forward model E
Enhanced Oil Recovery (EOR) Modeling: EOR simulation: model waterflooding, CO2 miscible, or polymer flooding to predict incremental recovery factor. The forward operator produces the measurement through a 3-node primitive DAG (M.fractional_flow.buckley_leverett…); recovery is posed as a parameter_estimation problem. Difficulty tier delta=5 with effective condition number kappa_eff~500; viscous_fingering_onset, gravity_override_degree set the accuracy floor at the Omega boundary. See the forward_model field for the closed-form equation.

Existence of the recovered 3D_saturation_composition is guaranteed within the declared Omega bounds. Uniqueness holds on the measurement-supported subspace; out-of-support modes are controlled by declared priors. Stability is conditionally stable (kappa_eff ~= 500); viscous_fingering_onset dominates the stability cliff; the remaining mismatch parameters contribute higher-order bias terms. Measurement gaussian sets the irreducible data-fidelity floor.
