Escalating Per-Well Plugging Costs Due to Depth, Age, and Complexity
Definition
P&A costs for natural gas wells exceed initial estimates due to factors like well depth, age, gas-specific challenges, and surface reclamation, with medians at $76k including reclamation and highs over $1M. Costs have risen sharply (e.g., vertical wells from $38k to $120k), and horizontal shale wells reach $261k-$415k. Systemic overruns occur as operators underfund bonds relative to true expenses.
Key Findings
- Financial Impact: $120k per conventional well; $261k-$415k per horizontal well; up to $1M outliers
- Frequency: Per well abandonment, recurring as production declines
- Root Cause: Variable factors like +20% cost per 1,000ft depth, older wells costlier, gas wells 9% more than oil, and recent inflation in materials/labor

Financial Impact
$100M-$300M (LNG operator with large legacy portfolio; permit delays cost $5M-$20M per month in lost export revenue; bonding shortfall = $100M+) • $100M+ (LNG export terminal with 300+ legacy wells; if 10% underbonded by $50k-$150k = $1.5M-$4.5M+ exposure; regulatory fines add 10-20%) • $10M-$40M (gas trading firm with multiple joint ventures; cost disputes, reconciliation delays)
Current Workarounds
Accountant receives P&A cost deduction notice from operator; validates against lease royalty terms; Excel spreadsheet tracks cumulative P&A deductions; disputes resolved via email/letter • Analyst receives hard-copy P&A cost invoices from operator; manually validates against joint operating agreement terms; calculates partner share in Excel; resolves discrepancies via email/phone • Excel spreadsheets with static cost estimates from 5+ years ago; manual email tracking of bonding positions; spreadsheet-based lease-by-lease abandonment obligation inventory
