# World Energy Field Explorer — analysis projection
Tabular projection of the **World Energy Field Explorer** analysis results, published so the
Hugging Face dataset viewer and the **datasets-server API** can render visualizations directly.
Live Explorer: https://vamseeachanta.github.io/worldenergydata/field-atlas/
## Tables (viewer configs)
| Config | Rows | What |
|---|---|---|
| `fields` | 10 | Lower-Tertiary fields — economics, reservoir, HPHT/decommission risk, concept, landman |
| `wells` | 56 | Producing wells — spud/TD/first-oil, rig-days, cumulative oil, uptime |
| `countries` | 84 | Global offshore funnel — per-country field counts + data-density badge |
| `parametric_economics` | 30 | WTI price-multiplier x discount-rate NPV grid (jack_st_malo, julia) |
## Economics basis
- `npv_mm` / `breakeven_wti` are **life-to-date**, pre-tax, 10%-discounted: full sunk capex
charged against oil produced to date, not full-cycle EUR. Fields early in life are withheld
(`economics_status = early_life`, values null) rather than surfaced as absurd numbers.
- `eur_mmbbl` is **curated published/booked recoverable reserves** with `eur_source` +
`eur_confidence` — NOT a decline-fit extrapolation. Null where no credible public figure
exists.
- `parametric_economics` sweeps a uniform multiplier on the historical monthly WTI deck and
the annual discount rate over the same sanctioned cashflow model. NPV is exact (affine) in
the price multiplier. Fields with withheld economics are excluded from the grid.
## Provenance
Schema version `1.0.0`. Derived from the committed Explorer results bundle
(`reports/field-atlas/results/explorer_results_bundle.json`), itself a projection of
`_explorer.json` + `_atlas_feed.json`. Source snapshots (sha256):
- `reports/field-atlas/results/explorer_results_bundle.json` — sha256 `05f2864caca2ba08…`
- `reports/lower_tertiary/lifecycle/_performance.json` — sha256 `0959bfd07588b8c1…`
- parametric grid: code revision `af2482fd842d`, config
`config/parametric/lt_economics_sweep.yml` (sha256 `8ffad49934092964…`), data window through
`2026-04-30`, model `worldenergydata.lower_tertiary.v30_financial_reproducer.build_field_npv_timeline`
## Revision notes
- **Economics refresh**: `eur_mmbbl` corrected to curated published reserves (the previous
revision carried inflated decline-fit values, since retired); life-to-date NPV / break-even
columns added for fields whose economics are surfaced; `parametric_economics` grid added.
## D&C days QA/QC tables
Bore-level drilling & completion days behind the World Oil April 2026
reconciliation (hub: https://vamseeachanta.github.io/worldenergydata/wo-april-2026-qaqc-hub.html).
| Config | Rows | What |
|---|---|---|
| `dc_development_summary` | 11 | Per-development rollup vs the article (7 exact, 3 explained) |
| `dc_bores` | 253 | Per-bore spud/TD, drill vs completion split, producer/sidetrack |
| `dc_vintage_diff` | 253 | Frozen-V30 vs wed — drilling changed on 0 of 253 bores |
Basis: canonical extractor output, BSEE WAR vintage 2026-02-19. Drilling days =
spud to TD; completion days = all post-TD rig time including later servicing
(the open #846 boundary question). Known caveat: DRILLING_DAYS mixes calendar
days (spans <=250 d) with WAR-union rig-days (longer spans), so batch-drilled
wells undercount — tracked in the QA/QC hub.
