Every inactive well
is a balance-sheet line item.
The first portfolio-level app for scoring oil & gas well decommissioning. Upload an inactive-well list — get priority-ranked plug & abandonment cost bands, risk flags, and an audit-defensible methodology in 30 seconds. Built for operators preparing reserves season, lenders sizing borrowing bases, and M&A buyers running diligence.
Prepare reserves & the ARO line
State bonding rules are tightening. Your CFO is asking what the inactive-well exposure really is. This app builds the inventory before reserves season starts.
Independent ARO red-flags
Reserve-based lending redetermination twice a year. Bank-quality independent verification of borrower's plugging-cost assumptions — without commissioning a full reserves report.
5-day asset diligence
Asset packages always under-disclose P&A liability. California AB 1167 now requires full bonding at transfer. Independent diligence in days, not weeks.
1. Upload or paste your well list
CSV with columns well_id, state, status, age_years, total_depth_ft, surface_acres, h2s, distance_to_population_m, inactive_years. Only well_id and total_depth_ft are required; the rest fall back to defensible defaults.
What you get — free
- ✓Per-well priority score (0–100)
- ✓Component cost: cement, casing, surface, environmental, regulatory
- ✓Portfolio rollup, by state, score histogram
- ✓Top 10 priority wells, ranked
- ✓No signup, no email — public output

Wide bands reflect the variance documented in RFF 2021 (Raimi et al.): $3,664 to $343,750 per well across state programs. This screening tool uses generalized coefficients; state-specific cost models are part of the paid P&A Inventory engagement.
Want this run on your real portfolio?
Up to 100 wells, fixed-scope P&A Inventory engagement starts at $10,000 — delivers state-rule-aware bonding gap, lender-ready PDF, and per-well Excel file in 5–10 business days. Stanford PhD reservoir engineer. Methodology grounded in NETL + RFF + state regulator data.
Methodology
Priority score
Multi-criteria decision analysis (MCDA). Each factor — age, depth, surface footprint, H2S presence, population proximity, inactive duration — is min-max normalized across your portfolio, then weighted-summed into a 0–100 priority score. Methodology aligned with publicly documented approaches in Osundare et al. 2018 and the NETL MERP tools.
Cost model
Component build-up: mob/demob, cement plugs, casing work, surface restoration, environmental, regulatory, H2S premium. Generalized $/ft coefficients calibrated against Raimi et al. 2021 (median plug-only $20K, plug + surface $76K) and IOGCC 2024 (2023 national average $41,139/well, range $3,664–$343,750). This is a screening output. Real engagements use state and basin-specific cost coefficients.
Screening tool — not a substitute for an engineering bid, a reserves report, or regulatory advice. For a defensible per-well audit, see the P&A Inventory service.
