Life-cycle insights · hub
Every offshore well runs the same arc: Drill → Complete → Produce → Workover → Decommission. Below, each stage links a single front-door analysis — one thesis, one number, computed from public BSEE data. The arc opens on 11,124 rig-days of Gulf-of-Mexico Lower-Tertiary drilling and closes on $65–73B of latent plug-and-abandonment liability still on the books.

Median 46.5 rig-days per development wellbore. Each extra 1,000 ft of TVD adds only ~3.3 days and depth explains just 11% of the spread — field execution and hole trouble, not geology, drive the curve.
Well-Activity-Report-derived drilling and completion durations across the twelve Lower-Tertiary fields, with medians by field — the existing completion surface.
Cross-field per-well production benchmarking on the same frozen data window as the sanctioned V30 economics — the existing benchmark surface.
270 subsea wells concentrate in the 5,000–10,000 ft band against only ~3 GoM-resident heavy intervention units — a 4.4× forward access-gap ratio and ~$1.0B/yr of exposure.
8,161 boreholes are drilled but not yet permanently plugged; at the model's $8–9M/well shelf cost that is $65–73B of latent liability, and the 3,288 already-temporarily-abandoned wells ($26B) are the imminent, Idle-Iron-overdue crest.
Cross-cutting comparisons · orthogonal to the spine
Two forces pull opposite ways: the North Sea costs 25–30% more per identical asset, but 159 FPSOs carry $14.8B of the $17.5B modeled bill — the asset mix, concentrated in Brazil / West-Africa deepwater, not the multiplier, sets the realized total.
Deepwater is wet-tree country: past ~1500 m the dry-tree share of producing trees collapses from 80% on the shallow shelf to 20% in ultra-deepwater.
Reference-depth coverage across 205 countries in atlas scope, 84 with offshore-field data, the Gulf of Mexico at full life-cycle depth — the honest map: 1 RICH region, 78 SAMPLE-reference, 5 ROADMAP.
How to read this hub. Each card is a presentation layer over a frozen, deterministically-computed report artifact — the numbers are identical for everyone, every time. The Complete and Produce stages link existing surfaces (WAR-derived completion days and cross-field benchmarking); the Drill, Workover and Decommission stages and both cross-cutting comparisons are the life-cycle insight front doors. Where a data source is partial, each front door says so in its own caveats rather than filling the gap with a guess.
