💡 Accountant's Note

Exploratory wells are drilled to test if oil or gas is present. The cost is capitalized pending determination of whether commercially viable reserves exist. If reserves are confirmed, the cost is reclassified to development; if not, it is written off.

Practitioner & Systems Framework

💻 ERP Architecture

Record all exploratory well costs (day-rate drilling contractor, mud and chemicals, well logging, casing, cementing, completion testing) to the E&E asset sub-account for that specific well. Use a project code structure by well name. Track against the approved well AFE (Authorization for Expenditure). The capitalized balance must be reviewed at each reporting date — if the well has been drilled more than 12 months without a commerciality determination, enhanced disclosure is required under IFRS 6 and the asset faces heightened impairment risk.

⚠️ Audit Flags

Auditors focus on the 'one-year rule' for suspended exploratory wells — costs can only remain capitalized beyond 12 months if (a) sufficient reserves have been found to justify completion and (b) management is actively making the commerciality assessment. They will request a timeline of management deliberations for any well suspended beyond one year. The well status report (drilling results, core/log analysis, reserve estimate) is the primary supporting document.

📄 Required Documentation

Well AFE (Authorization for Expenditure) approved by management and partners, daily drilling report, well completion report and mud log, wireline log interpretation, reservoir engineering assessment of discovered volumes, Management's commerciality assessment (updated at each reporting date for suspended wells), and partner joint interest billings.
