How to Expense a Stratigraphic Test Well Drilled Purely for Geological Data Collection
Expensing the cost of a well drilled solely to obtain subsurface geological data with no production intent.
| Account Name | Type | Debit ($) | Credit ($) |
|---|---|---|---|
| Exploration Expense — Stratigraphic Test | Expense (+) | 3,500,000.00 | - |
| Cash / Accounts Payable (Drilling) | Asset/Liability (-) | - | 3,500,000.00 |
💡 Accountant's Note
Stratigraphic test wells drilled solely for geological data with no production intent are expensed under successful efforts accounting. Under full cost accounting, they are capitalized to the cost pool.
Practitioner & Systems Framework
💻 ERP Architecture
The accounting treatment depends on the company's accounting policy: (a) Successful Efforts: Stratigraphic test wells are expensed because their purpose is data collection, not reserve delineation or development. (b) Full Cost: All drilling costs are pooled and capitalized to the country-level cost pool. Most IFRS-reporting companies use successful efforts or a variant of it. Document the purpose of the well in the drilling authorization — the stated purpose determines the accounting treatment.
⚠️ Audit Flags
The classification of a well as a 'stratigraphic test' (expensed) vs. an 'exploratory well' (capitalized) is a judgment area. Auditors examine the drilling authorization and geotechnical objectives to confirm the well's purpose. A well that discovers hydrocarbons but was drilled as a stratigraphic test still requires the cost to be expensed (unless reclassified as an exploratory well at inception, which is difficult to do retrospectively).
📄 Required Documentation
Drilling Authorization (well type stated as stratigraphic test, geological objectives), AFE approved before spud, drilling report confirming data collection activities (no completion or production test), geological data analysis report, and accounting policy disclosure distinguishing stratigraphic tests from exploratory wells.
