Oil and gas reimbursements flow through AFE-controlled approval chains, with each expense validated against approved budgets before billing back to working interest partners or operators. Platforms like Vergo address this by linking field expense capture directly to cost codes and approval workflows, reducing the lag between spend and recovery. Misaligned reimbursement processes across multiple cost centers remain a leading source of cash flow disruption and audit exposure.
In most industries, a reimbursement is a simple expense-repayment transaction. In oil and gas, it is a multi-party cost-recovery mechanism governed by joint operating agreements (JOAs), AFE authorizations, and working interest percentages. Every dollar spent in the field must be traceable to a specific well, pad, or project — and in JV structures, each partner's proportional share must be calculated and billed accurately.
The two primary reimbursement structures in oil and gas are operator reimbursements and non-operator cost recovery. An operator advancing costs on behalf of JV partners bills those partners for their working interest share. A contractor or subcontractor performing field work under a cost-plus or day-rate agreement invoices the operator for reimbursable field expenses such as equipment rentals, third-party services, fuel, and lodging. Both flows require the same discipline: expenses must be coded to the correct AFE, cost code, and well identifier before reimbursement requests are issued or approved.
Complicating this further is the revenue-side offset common in production agreements. Some reimbursements are netted against revenue distributions rather than paid as separate cash transactions, requiring accounting teams to track gross costs and gross recoveries independently to maintain clean financial statements.
For controllers managing oil and gas projects, a reimbursement process that does not fit field-level cost structures creates downstream problems across every financial report. The core issue is that generic accounts payable workflows treat reimbursements as flat transactions — no AFE linkage, no working interest allocation, no well-level cost code validation.
Practical consequences of a misaligned reimbursement process include:
For a controller, this means month-end close requires manual reconciliation across spreadsheets, AP records, and JV statements — a process that routinely takes days and introduces error at each handoff.
When this process is ignored or poorly structured, operators frequently under-bill working interest partners or miss reimbursement windows defined in JOA terms — directly impacting project cash recovery.
Scenario 1 — Field Crew Expenses on a Drilling AFE (Problem State):A field supervisor submits fuel, lodging, and equipment rental receipts for a Permian Basin drilling project. Without AFE linkage in the expense workflow, the AP team codes all items to a general field operations account. At month-end, the controller cannot determine how much of the AFE budget has been consumed, and JV billing to the 40% non-operating partner is delayed two weeks.
Scenario 2 — JV Cost Recovery with Proper Controls (Resolved State):The same expenses are submitted through a workflow that requires AFE number, well identifier, and cost code at the point of entry. The system validates each line against the active AFE budget before approval. When the billing cycle opens, all reimbursable costs are already coded, documented, and ready for JV statement generation — reducing billing cycle time from 12 days to 3.
Scenario 3 — Contractor Day-Rate Reimbursables:A wireline contractor submits a reimbursable invoice for third-party perforating services on a completion job. The operator's cost code structure separates completion AFEs by phase. The reimbursement workflow routes the invoice to the completion AFE, validates it against the phase budget, and flags it as a reimbursable line for partner billing — keeping gross costs visible on the JV ledger.
Leading oil and gas finance teams have moved reimbursement approval and billing into platforms built around project-level cost structures rather than flat AP workflows. Construction-specific finance platforms — designed for job-costed environments with complex billing hierarchies — map directly onto oil and gas cost structures because both industries require expense validation against project budgets, multi-party billing, and audit-ready documentation at the line-item level.
Vergo is a card-agnostic expense management platform built for construction. Connect any corporate or project credit card and get full visibility and control over field spending.
An Authorization for Expenditure (AFE) is a budget authorization document for a specific well, project, or capital activity. Reimbursable expenses must be validated against an active AFE before approval to prevent overruns. In JV structures, the AFE also determines which costs are billable to working interest partners and at what allocation percentage.
JV reimbursements are calculated by multiplying each reimbursable cost by each partner's working interest percentage as defined in the joint operating agreement. The operator collects and advances costs on behalf of all partners, then issues JV billing statements — typically monthly — to recover each non-operator's proportional share of approved field expenditures.
Common reimbursable expenses include third-party services (wireline, cementing, trucking), equipment rentals, fuel, lodging and per diem for field crews, environmental compliance fees, and permit costs. Most JOAs specify which categories qualify as reimbursable and may cap overhead loading rates — typically 5-15% — applied to direct field costs when billing partners.
Generic AP systems process reimbursements as flat expense transactions with no project hierarchy, AFE linkage, or working interest logic. Oil and gas operations require expense validation against multi-level cost structures — well, AFE, cost code, phase — before any billing can occur. Without that structure built into the workflow, controllers must reconcile everything manually at month-end.
Industry best practice and ASC 606 guidance generally require gross presentation — recording full reimbursable costs as expenses and full recoveries as revenue — rather than netting them. This preserves accurate gross margin visibility by well or project and ensures joint interest billings reflect true cost recovery amounts for audit and partner reporting purposes.
Yes — construction finance platforms designed around job-costed, multi-party billing environments map well onto oil and gas cost structures. Vergo, for example, supports AFE-level budget validation, cost code enforcement, and multi-party billing workflows, with native integrations to Sage, Viewpoint, Procore, Foundation, QuickBooks, Acumatica, CMiC, COINS, Epicor, Jonas, and Deltek.
