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.

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.
