D&C Days QA/QC
One entry point to the whole reconciliation — the field-level matrix, the bore-by-bore listing, the drilling-days resolution, and the revision lineage. Everything below is reachable from this page, and every number traces to committed extractor output.
Reconciled to the article — completion-boundary rule (#846) openΔ vs the article, by development
Total D&C days, wed minus World Oil Table 1 — seven exact, three explained.
The report set
How it holds together
Five report roles, grouped by how deep you're going. Start with the reconciliation narrative, drill into the bore-level data, then follow the one open accounting question. Each card carries an evidence badge so you always know what weight the page can bear.
Understand
Validation & Matrix
The field-level D&C reconciliation against the article as published, plus the article errata hand-back.
- 7 exact · Shenandoah +24 resolved · Buckskin recovered
- Post-cutoff delta isolated: +53 days, all servicing
- BOEM cross-check and change log
Revision Lineage
V30 → V50 → wed, field by field — the canonical-basis story behind every number on these pages.
- V50 = wed to the day, every field
- What changed at each revision and why
- The bug corrections, documented
Explore the data
Drill-Down
Browse by field or OCS block, drill to the bores, then to a single wellbore’s full record.
- 11 fields · 23 blocks · 253 bores
- Every level deep-linkable
- Out to life-cycle, economics, assets
Per-Well Listing
One row per wellbore behind every matrix cell — the "listing" the QA/QC review asked for.
- Spud, TD, drilling / completion split per bore
- Producer and sidetrack markers
- Article comparison columns per development
Drilling-Days Resolution
Frozen V30 vs wed, per bore — drilling days never change once TD is reached; all movement is data arrival.
- 0 of 253 bores changed drilling days
- 7 late-data bores · 5 servicing-accrual bores
- Known caveat: two bases in one column — calendar ≤250 d, WAR-union beyond; batch-drilled wells undercount (PS004: 44 d at 28,692 ft)
The open question
JSM D&C Diff
The +234-day frozen-vs-candidate difference localized to two producer bores — every boundary rule tested regresses another field's pins.
- 608124015400 · +48 drill / +71 compl
- 608124015504 · +68 drill / +47 compl
- Rule sensitivity table → owner decision
Frozen Verification
The like-for-like check against the article's own frozen V30 universe — 217 wells, matched-9 within −2.5%.
- 22,478 wed vs 21,944 article D&C days
- Same universe, same vintage, same rules
- The WO_APRIL_2026_ARTICLE pinned benchmark
