How do oil and gas companies handle expense management?

Key takeaways

• Vergo codes transactions by project, GL account, or amount, with real-time visibility and ERP integration, enabling field crews to submit expenses with AFE validation at the point of capture.
• Oil and gas expense management requires every dollar to be traceable to a specific cost object: a well, lease, field, AFE, or pipeline segment.
• AFEs (Authorizations for Expenditure) serve as the foundational control document, tracking committed, incurred, and forecasted spend against project budgets in real time.
• Joint interest billing allocates operator-incurred expenses to working interest partners by ownership percentage, requiring clean expense data to avoid billing disputes.
• Misclassification between lease operating expenses, capital expenditures, and exploration costs distorts depletion calculations, tax treatment, and SEC reporting.

What makes oil and gas expense management different

Expense management in oil and gas is not a variation of standard corporate accounting — it is a structurally distinct discipline. Every dollar spent must be traceable to a specific cost object: a well, a lease, a field, a pipeline segment, or an AFE (Authorization for Expenditure). Unlike general and administrative expense tracking, oil and gas costs are divided across three fundamental categories: lease operating expenses (LOE), capital expenditures (CAPEX), and exploration costs — each carrying different tax treatment, depletion implications, and SEC reporting requirements. The AFE is the foundational control document. Before a project begins — drilling a new well, completing a workover, or installing compression equipment — an AFE is issued with a budgeted cost. Every subsequent expense is coded against that AFE, allowing operations and finance to track committed, incurred, and forecasted spend in real time. When an AFE is exhausted or at risk of overrun, a supplemental AFE is issued. Vergo proposes the coding by inference from your own accounting structure and history — no rule library to build, no keyword lists to maintain, and new vendors are coded on first sight.

How joint interest billing complicates the process

Joint interest billing (JIB) adds another layer of complexity to oil and gas expense management. When wells are co-owned by working interest partners, expenses incurred by the operator must be allocated to each partner's ownership percentage and billed monthly. Every field expense — from chemicals and saltwater disposal to contractor labor and equipment rentals — must flow through this allocation process before JIB statements are issued. Coding errors create billing disputes with working interest partners that are costly and time-consuming to resolve. Clean expense data at the point of capture is essential: the operator must be able to trace each expense from field receipt to AFE, to cost category, to partner allocation, and finally to the JIB statement. Without this traceability, billing cycles are delayed and disputes multiply. Vergo codes transactions the moment they happen — no waiting for clearing — and syncs them into your accounting or ERP software with complete audit trails.

Why this matters for controllers

For a controller in an oil and gas company, a broken expense management process creates downstream failures across the entire accounting cycle. Misclassified expenses — CAPEX coded as LOE, for example — distort depletion calculations, overstate or understate taxable income, and trigger audit exposure under IRS Sections 263 and 611. These are not rounding errors; they are material misstatements. AFE overruns go undetected until month-end close, leaving no window for operational correction. Field crews submitting expenses often lack visibility into AFE codes or cost center structure, leading to incomplete or miscoded submissions. Multi-state and offshore operations introduce severance tax, ad valorem tax, and federal royalty considerations that must be tied back to specific lease expenses. Audit readiness requires that every expense be traceable from field receipt to financial statement line item. When these systems fail, controllers spend weeks reconstructing transactions at quarter-end instead of managing forward-looking financial performance.

A practical example

A field supervisor on a workover job in the Permian Basin submits expenses via email and paper receipts. The AP team codes them to the general well cost center without an AFE reference. At month-end, the controller discovers the AFE is 40% over budget, too late to pause non-essential work. JIB statements are delayed because the expense split cannot be confirmed. In a structured process, the same supervisor uses a mobile expense submission tool that requires an AFE number and cost code before the expense is accepted. The system validates that the AFE has remaining budget and routes the expense to the appropriate approver based on dollar threshold. The controller sees real-time AFE utilization daily, and JIB statements close on schedule with a complete, auditable expense trail. Vergo handles this through text message — no app to download, no portal login — and chases missing receipts itself instead of waiting for a report.

Exploration cost tracking requirements

A company evaluating three prospective leases in the DJ Basin must track geological consulting fees, seismic data purchases, and land broker costs to each lease individually under full-cost or successful-efforts accounting methods. Aggregating these expenses into a single exploration cost center destroys the traceability required when a lease is abandoned or a well is brought into production. Each exploration expense must carry a lease identifier from the moment it is incurred, so that capitalized costs can be matched to proved reserves or written off when prospects are abandoned. This level of granularity is impossible to reconstruct after the fact if field personnel submit expenses without lease-level attribution. Controllers need systems that enforce cost object assignment at the point of capture, not during monthly close. Vergo approval workflows are optional and fit how you already control spend: route by GL account, by amount, or by project — or skip approval flows entirely and let policy flags catch only what breaks a rule.

How Vergo handles this

Vergo is an AI-native, card-agnostic expense management platform that handles card spend, employee reimbursements, and AP invoices through one coding model. Vergo proposes the coding by inference from your own accounting structure and history — no rule library to build, no keyword lists to maintain, and new vendors are coded on first sight. Every coding shows why it was chosen, so a reviewer confirms in seconds instead of re-coding by hand. Approval workflows are optional and fit how you already control spend: route by GL account, by amount, or by project — or skip approval flows entirely and let policy flags catch only what breaks a rule. Transactions are ready to code the moment they happen — no waiting for clearing — and once they clear, they sync into your accounting or ERP software. Employees handle everything by text message — no app to download, no portal login — and Vergo chases missing receipts itself instead of waiting for a report. Connecting your existing cards involves no card applications, no re-issuing and no banking change. Vergo integrates with every ERP and accounting software.
