Everyday complex engineering —
made deterministically simple.

Global offshore field drill-down — fields, wells, and country rollups built from BSEE and public regulatory filings.

Coverage is primarily US Gulf of Mexico deepwater (BSEE) plus selected international basins; not a complete global census. Published fields emphasize operational, geological, production, and provenance attributes. Economics are intentionally absent from this table while the upstream economics configuration is being republished and reviewed.

Standard-traceable parametric result grids — mooring fatigue (S-N), synthetic-rope fatigue (T-N), and riser code-check utilisation — from digitalmodel's validated reduced-order atlases.

Synthetic parametric sweeps generated from the cited standards (DNV-RP-C203, DNV-OS-E301, API-RP-2RD) and validated to under 10% max relative error against held-out samples. For screening and capability demonstration — not a substitute for a project-specific engineering check.

Field-economics sensitivity sweep — how life-to-date pretax NPV moves with WTI price and discount rate, on public BSEE production.

Bore-by-bore drilling & completion days behind the World Oil April 2026 reconciliation — 253 wellbores across 11 Gulf of Mexico developments, with drilling-day stability proven across data vintages. Browse the interactive drill-down: /capabilities/dc-drilldown.html

Drilling days = spud to total depth; completion days = ALL post-TD rig time including later recompletion and servicing (the open worldenergydata#846 boundary question). Known caveat: the extractor mixes calendar days (spans under ~250 d) with WAR-union rig-days (longer spans), so batch-drilled wells undercount drilling days — disclosed rather than corrected pending resolution. Producer markers cover the seven core Lower-Tertiary fields only.

OpenFOAM VOF sloshing analysis for partially filled tanks — free-decay validation against closed-form theory, a forced-roll period sweep, and the connected twin-tank U-tube exchange mode with its inter-tank mass shift and roll moment.

Source-neutral reference geometry only — no vessel-specific dimensions are published here. Free-decay frequency matches closed-form theory to 0.30%; the conduit-area scaling law matches CFD to ~1-2%. Absolute forced magnitudes carry a single dynamic-amplification factor (x1.34 to x1.45) measured near resonance, and the connected-tank mass shift and roll moment are derived from the CFD-measured level difference rather than predicted independently.
