💡 Accountant's Note

Development wells are drilled after commercial reserves are confirmed. Their costs are capitalized to the oil and gas property and depleted over the proved developed reserves using the Units of Production (UOP) method.

Practitioner & Systems Framework

💻 ERP Architecture

Development well costs include all drilling, casing, cementing, completion, and wellhead equipment costs. Capitalize all directly attributable costs from spud date through first production. Track against an approved well AFE and record cost overruns separately for management reporting. The capitalized development well cost is added to the field's Development Asset pool and depleted using the UOP method alongside other development costs. Update the UOP depletion rate to reflect the new proved developed reserves added by the well.

⚠️ Audit Flags

Auditors verify that the development well costs are genuinely for a well in a proved field — development wells must be in areas with proved reserves to qualify for capitalization. Costs incurred to drill in unproved areas adjacent to a development are treated as E&E costs, not development costs, until reserves are confirmed. They also check that workover costs (maintenance drilling) are correctly expensed rather than capitalized as new development assets.

📄 Required Documentation

Well AFE approved by management and JV partners, daily drilling report, well completion report, wireline logs confirming production zone, wellhead equipment commissioning record, first production date (depletion start date), updated proved developed reserve estimate, and capitalized cost reconciliation to AFE.
