A detailed budget document itemizing the expected costs of a drilling project or well, which investors and partners approve before operations begin.
An Authorization for Expenditure is a formal budget outline prepared by the operator that lists all anticipated costs for drilling and completing a well (or for a major project). It breaks down expenses into categories (like site preparation, drilling, completion, facilities, etc.) and provides cost estimates for each. Joint venture partners and investors review the AFE and must approve it, agreeing to fund their share of the costs. The AFE then serves as a financial guideline during operations, and actual costs are later compared to this budget to track variances. Having an AFE in place ensures all parties are aware of the financial commitment and helps prevent disputes over spending.
The AFE gives investors transparency into the cost structure of a project upfront and sets expectations for capital calls. By approving an AFE, investors commit to the budget, so it’s a critical tool for due diligence. Monitoring actual costs against the AFE also helps investors ensure projects are managed within budget or understand why overruns occur.
