The Oil and Gas Loan Application Checklist: Reserve Reports to Title Opinions

By MercFinancial · Published 2026-09-01 · Updated 2026-09-07

An oil and gas loan application is built around a reserve report, lease operating statements, production history, title and division orders, hedging, environmental and plugging liabilities, and financials. Here is what each is for and where files stall.

An oil and gas loan application is built around a small set of documents that let a lender value the collateral and confirm you own it: a reserve report prepared by a petroleum engineer, lease operating statements and production history for each property, title opinions and division orders, your hedging position, an account of environmental and plugging liabilities, and the entity and personal financial documents any commercial loan requires. Files move at the speed of the slowest of those, which is almost always title or the reserve report.

This checklist goes document by document: what each one is, who prepares it, what the underwriter actually reads in it, and how it connects to the others. It closes with the sequence a well-run application follows and the places files reliably stall. It applies to reserve-based loans, acquisition financing and development facilities alike; the emphasis shifts, but the documents do not.

"I sent the lender my production numbers and a spreadsheet and figured underwriting would start. It started the day the reserve report and the title opinion arrived, six weeks later, and both were things I could have ordered before I ever applied."

The Reserve Report: Who Prepares It and What Lenders Read

The reserve report is the valuation of your collateral. For bank reserve-based loans it is prepared by an independent petroleum engineering firm; smaller private lenders sometimes accept an in-house report or run their own evaluation. It classifies reserves as proved developed producing, proved developed non-producing and proved undeveloped, projects each well's production along a decline curve, deducts operating costs, taxes and future capital, and discounts the cash flow to a present value, the figure usually labeled PV-10.

The underwriter does not take the report at face value. The lender re-runs the projections on its own price deck, which sits below the futures market, applies its own discount rates by reserve category, and gives most of the credit to producing reserves. Two things you control matter most: the report's effective date, because lenders want current data and a stale report is re-ordered, and the quality of the inputs, because an engineer works from the production, cost and ownership data you supply. Order the report early, before the application, and have the engineer use the same property list and interests that your title work will confirm.

Lease Operating Statements and Production History

A lease operating statement shows, for each property and month, the volumes sold, the revenue received, the production and ad valorem taxes, the lease operating expenses and the resulting net operating income. Lenders want a year or more of them, and they read them for trend, for cost per barrel or per thousand cubic feet, and for anything unusual: a workover that spiked expenses, a shut-in month, a purchaser change.

Production history comes from purchaser statements, run tickets and the public records of the state regulator, and the underwriter reconciles it against the operating statements and the reserve report. Where the three disagree, underwriting stops until someone explains why. Reconciling them yourself before submission, property by property, is the single most time-saving thing an applicant can do.

Title Opinions, Division Orders and Ownership Documents

Title is where oil and gas loans are slowest, because the lender needs to know, for every property, exactly what interest you own and that nothing senior stands in front of it. The documents are the leases and a schedule of their status, the assignments that carried the interest to you, the joint operating agreements, and title opinions. A drilling title opinion is prepared before a well is drilled; a division order title opinion is prepared after completion and sets the decimal interest each owner is paid on. For an acquisition, the lender wants an acquisition title opinion or, at minimum, current run sheets with the curative work identified.

Division orders and the purchaser's payment history prove that the interest in the opinion is the interest being paid. The lender also runs its own searches for recorded liens, financing statements and unreleased mortgages. Curative items, such as an unreleased lien from a prior lender, a missing probate in a mineral chain or a gap in an assignment, are the usual reason a closing date moves; find them before the lender does.

Hedging, Marketing Contracts and Price Protection

Most bank lenders require you to hedge a portion of projected producing volumes for a set period as a condition of the loan, using swaps or collars documented under a master agreement with the lender or an approved counterparty. The application should state your existing hedges, the counterparties and the volumes and periods covered, and be ready for the lender to require more at or before closing. Private lenders vary; some require hedging, others price the risk instead.

Alongside hedges, the lender reads the contracts that turn production into cash: crude purchase agreements, gas marketing contracts, and gathering, processing and transportation agreements. Term, pricing basis, dedication and termination rights all affect the revenue the reserve report assumes. How the borrowing base moves with prices afterward, and how hedges cushion it, is explained in our borrowing base redetermination FAQ.

Environmental, Plugging and Regulatory Standing

Every producing property carries obligations that arrive after the revenue stops, and lenders underwrite them. Expect to provide a schedule of every well by status, including inactive wells and their plugging plans, and an estimate of plugging and abandonment costs, which the lender will compare against the reserve report's assumptions. Wells that are inactive without a current extension from the regulator, or that have compliance issues on file, are excluded from the collateral or reserved against.

Environmental review covers spill history, remediation obligations, saltwater disposal permits and, where surface facilities or acquired properties are involved, a Phase I environmental site assessment. The lender also confirms the operator's registration and financial assurance with the state regulator are current, because a lapse can shut in production regardless of how good the wells are.

Entity, Guarantor and Transaction Documents

The remainder of the file is what any commercial lender requires, adjusted for the industry. Entity formation documents, certificates of good standing, an ownership chart and authorizing resolutions. Business tax returns and year-to-date financial statements, a debt schedule and bank statements. Personal financial statements and tax returns for each guarantor. Certificates of insurance, including well control coverage. For an acquisition, the purchase and sale agreement with its exhibits and the seller's data room; the acquisition-specific requirements are covered in financing a producing oil well acquisition. For a development facility, the AFEs, the drilling schedule and the operator's history on offset wells.

The Sequence, and Where Files Stall

Files stall on a short list: title curative that was not started early, a reserve report with a stale effective date or the wrong interests, operating statements that do not reconcile to purchaser statements, hedges not in place by closing, plugging liabilities that were never scheduled, and liens from a prior lender that were never released. Every one of them is visible before application.

Frequently Asked Questions

Who prepares the reserve report for an oil and gas loan?

For bank reserve-based loans, an independent petroleum engineering firm acceptable to the lender. Smaller private lenders sometimes accept a report prepared by the operator's own engineer or evaluate the reserves themselves. Either way the lender re-runs the projections on its own price deck and discount rates, so the report's role is to supply verified production, cost and ownership inputs.

What is a lease operating statement?

A monthly statement for each property showing volumes sold, revenue, production and ad valorem taxes, lease operating expenses and net operating income. Lenders use a year or more of them to confirm the reserve report's cost and revenue assumptions and to spot trends or one-time events. They must reconcile to the purchaser statements and the public production records.

Do I need a title opinion to get an oil and gas loan?

Yes, in some form. Lenders need to confirm the exact interest you own in each property and that no senior liens or gaps in the chain stand ahead of them. Depending on the loan, that means existing drilling and division order title opinions, an acquisition title opinion, or current run sheets with curative items identified and cleared before closing.

Do lenders require hedging on oil and gas loans?

Most banks require you to hedge a portion of projected producing volumes for a set period, using swaps or collars with the lender or an approved counterparty, and to keep those hedges in place as a covenant. Private lenders are split; some require hedging and others price the commodity risk into the loan. Ask early, because executing hedges takes time and documentation.

How long does an oil and gas loan take to close?

In general terms, from several weeks to a few months, with the reserve report and the title work setting the pace. A file that arrives with a current reserve report, reconciled operating statements and title curative already identified moves at the lender's speed; a file that orders those after application moves at the engineer's and the landman's.
