How to Write Off a Dry Hole Exploratory Well When No Commercial Reserves Are Found
Writing off the full cost of an exploratory well after it is determined to contain no commercially viable hydrocarbons.
| Account Name | Type | Debit ($) | Credit ($) |
|---|---|---|---|
| Dry Hole / Exploration Write-Off (Expense) | Expense (+) | 18,000,000.00 | - |
| Exploration & Evaluation Assets (E&E) | Asset (-) | - | 18,000,000.00 |
💡 Accountant's Note
A dry hole is an exploration failure. When a well proves non-commercial, all associated E&E costs must be written off immediately. This is one of the highest-risk aspects of oil & gas accounting — explorers may write off many wells before finding a commercial discovery.
Practitioner & Systems Framework
💻 ERP Architecture
The write-off is triggered by the management decision to abandon the well — typically evidenced by a Well Operations Report confirming no commercial quantities. Process the write-off in the period the decision is made, not when the well is physically plugged and abandoned (P&A). Maintain a separate Dry Hole Expense line on the income statement for transparency. The write-off is immediate and full — no partial write-down is permitted. Update the exploration dashboard showing cumulative dry hole costs vs. discoveries to date.
⚠️ Audit Flags
Delayed dry hole write-offs are one of the most common earnings management risks in E&P. Auditors will test whether the company has a documented decision date for abandoning the well and whether that date matches the write-off period. Management communications (Board papers, partner notifications, competent person reports) are key evidence. For wells suspended beyond 12 months, the presumption shifts toward write-off unless active commerciality assessment is documented.
📄 Required Documentation
Well Abandonment Decision paper (Board or investment committee sign-off), geological/geophysical assessment confirming no commercial reserves, Competent Person's Report or independent reserve assessor opinion, well completion report confirming formation evaluation results, partner notification of dry hole status, and plugging and abandonment plan.
