How to Capitalize a Water or Gas Injection Well Drilled for Reservoir Pressure Maintenance
Capitalizing the drilling and completion cost of an injection well designed to maintain reservoir pressure and maximize production.
| Account Name | Type | Debit ($) | Credit ($) |
|---|---|---|---|
| Development Assets — Injection Wells | Asset (+) | 15,000,000.00 | - |
| Cash / Drilling Contractor | Asset (-) | - | 15,000,000.00 |
💡 Accountant's Note
Injection wells are development assets — they maintain reservoir pressure to maximize production from the field. Their cost is capitalized and depleted using UOP over the associated producing reserves.
Practitioner & Systems Framework
💻 ERP Architecture
Injection wells (water injection for pressure maintenance, gas injection for gas recycling or EOR, CO2 injection) are development assets because they are part of the production system that converts proved reserves to revenue. Capitalize all drilling, completion, and wellhead costs. Include in the development asset pool and deplete using UOP alongside producing wells. Water handling facilities (produced water treatment and re-injection equipment) may be a separate component with a different useful life.
⚠️ Audit Flags
The distinction between injection for pressure maintenance (a development asset — capitalizable) and injection for EOR (enhanced recovery — may be capitalizable or expensed depending on whether new reserves are being added) is a key audit point. If an injection well is drilled in an area where no reserves have been proved, it cannot be capitalized as a development asset.
📄 Required Documentation
Reservoir engineering study supporting the injection program and pressure maintenance benefit, AFE for the injection well, drilling and completion invoices, well commissioning report confirming injection operations, updated proved reserve estimate reflecting the pressure maintenance benefit, UOP depletion calculation, and regulatory approval for injection operations (environment and reservoir management).
