Bank or Private Lender for Your Oil and Gas Loan?

By MercFinancial · Published 2026-07-18

A decision framework for choosing between a commercial bank and a private energy lender for your oil and gas loan, by speed, cost, and leverage.

Choose a commercial bank for your oil and gas loan when your production history, PDP-weighted reserves, and covenant capacity can support a reserve-based line priced off prime or SOFR. Choose a private or specialty energy lender when you need speed, leverage beyond a conservative borrowing base, or a deal story a bank's redetermination model simply isn't built to underwrite. Most operators who stay in the business long enough end up using both, at different points in the same well's life, not one or the other forever.

That's the honest answer, but it isn't the whole answer. "Which lender type" is really shorthand for a handful of smaller questions about cost, control, and timeline that most operators have never had to rank before. A landowner converting a family lease into an active drilling program has different priorities than a ten-year operator refinancing a producing package to fund a workover — and the right lender for each can look completely different, even though both are technically "oil and gas loans."

"I called three banks before I understood none of them were going to touch a deal this size with this little production history. Nobody told me private capital was even an option until I was three weeks into a dry hole of phone calls."

The Decision in Brief: Match the Lender Type to Your Deal's Speed, Size, and Story

Before the detail, the shorthand. Lenders in oil and gas funding sort into two broad camps built for different kinds of borrowers.

• Commercial banks want seasoned production, a defensible engineering report, clean title, and enough cash flow cushion to survive a redetermination without a default. In exchange, they offer the cheapest capital in the market.
• Private credit funds and specialty energy lenders want a workable asset and a repayment story, but they'll tolerate thinner history, faster timelines, and structures banks won't touch — for a materially higher cost of capital.

Neither camp is "better" — they're built for different risk profiles, and a deal rejected outright by a bank's credit committee can be a perfectly ordinary underwrite for a private energy fund the same week. The mistake most operators make isn't picking the wrong lender; it's picking a lane before they know what either lane will actually offer.

Why Fewer Banks Do Energy Lending Than a Decade Ago

If it feels harder to find a bank that still does energy lending than it used to, that's not your imagination. The number of regional and super-regional banks running dedicated energy desks has shrunk meaningfully since the mid-2010s downturns, and the survivors have gotten more conservative, not less — commodity cycles, a wave of small-operator bankruptcies, and heightened regulatory scrutiny of concentrated energy exposure pushed credit committees toward tighter borrowing bases and a strong preference for multi-year track records. The practical effect: the pool of banks actively competing for your deal is smaller than it looks from a search, and the ones still in it are choosier. That's the gap private credit and specialty energy lenders have grown into — not by being cheap, but by underwriting deals banks quietly stopped chasing.

Commercial Banks: Cheapest Capital, Tightest Box

A bank reserve-based loan (RBL) is still the lowest-cost way to borrow against proved producing reserves, and it isn't close. Rates are typically priced off a spread to SOFR or prime, well inside what any private lender will quote, and the structure — a revolving line secured by a borrowing base tied to engineered reserves — flexes with production over time. The tradeoff is the box you have to fit inside. A conventional bank RBL generally wants:

• A defensible reserve report, weighted heavily toward proved developed producing (PDP) value rather than undeveloped locations.
• An operating history long enough that the bank isn't underwriting a projection — usually multiple years, not months.
• Financial covenants — leverage, current ratio, interest coverage — tested quarterly, with real consequences for a miss.
• A borrowing base redetermination typically twice a year, which can shrink your line if prices or production disappoint.

None of that is a knock on banks — it's what makes their capital cheap. A lender taking on less risk through conservative advance rates and tight covenants can afford to charge less for the money. The problem is timing: operators who most need capital right now — a young program, a recent acquisition, a company mid-workover — are frequently furthest from qualifying. For the mechanics of the borrowing base itself, see how reserve-based lending works and what happens at a redetermination.

Private and Specialty Lenders: Flexibility and Speed at a Price

Private credit funds, specialty energy lenders, and non-bank finance companies fill the space banks have vacated, and they do it by underwriting differently, not just charging more. A private lender can typically move faster because there's no committee cycle and no regulatory capital rules dictating the loan's treatment. They can lend against a shorter production history, undeveloped locations, or a story — an acquisition closing in three weeks, a completion program that needs capital before first production. What you pay for that flexibility is real. Rates run well above bank pricing, structures often include an equity kicker or overriding royalty interest alongside the debt, and terms tend to be shorter — built to be refinanced or repaid out of a specific event, like a well coming online or a bank refi. Covenant packages tend to be lighter, though, and a private lender is generally more willing to work through a rough quarter than trigger a technical default.

This is the part of the market where most drilling and completion capital and acquisition bridge financing actually get placed — deals that need to move on a timeline, or against an asset story, a bank's standardized program simply isn't built to accommodate.

Five Questions That Point You to the Right Side

Run your deal through these before you spend weeks chasing the wrong kind of lender.

• How long have you been producing from these wells? Years of clean history points toward a bank; a recent completion or acquisition points toward private capital.
• How fast do you need the money? A bank RBL closing typically runs weeks to a couple of months once underwriting starts. An acquisition closing in three weeks, or a completion racing a rig slot, usually rules banks out.
• Can your cash flow survive a covenant miss? If a slow quarter would put you close to a leverage or coverage covenant, a tightly covenanted bank facility adds default risk on top of the commodity risk you're already carrying.
• Is the collateral mostly PDP, or does it lean on undeveloped locations? Banks discount or exclude undeveloped reserves from the borrowing base. Private lenders will underwrite more of the story.
• What's the exit? A clear path to refinancing later — production ramps, a strong redetermination, an asset sale — makes a private bridge facility sensible even at a higher rate.

Most operators answer "bank" to one or two of these and "private" to the rest — which is exactly why so many end up doing both, sequentially, rather than picking one lender type for the life of the company.

Hybrid Paths: Starting Private and Refinancing to a Bank Later

The most common real-world pattern isn't "bank or private" — it's private first, bank later. An operator uses private or specialty capital to fund the acquisition, completion, or working capital gap a bank wouldn't touch yet, builds a track record over twelve to twenty-four months, then refinances into a bank RBL once the asset qualifies. Done deliberately, that sequence often produces a lower blended cost of capital than waiting for bank terms that were never going to be available on day one.

A checklist of exactly what a lender — bank or private — wants to see before it opens a file: what oil and gas lenders look for.

Seeing Both Markets at Once Through a Wholesale Broker

Here's the part most operators find out too late: you don't have to guess which side of this market you belong on before you start shopping. A commercial funding brokerage works across both — commercial banks and private energy credit, in the same submission — and lets the actual terms decide. MercFinancial runs your file through 160+ wholesale lender relationships across eight funding programs, covering both bank and non-bank energy capital, so you see real offers from both camps side by side. That matters most where the five questions above come out mixed — a deal close enough to bank-qualified that it's worth finding out for certain, without burning the weeks a bank underwriting process takes if the answer turns out to be no.

Frequently Asked Questions

Do banks still lend to small oil and gas operators?

Yes, but the pool of banks actively running energy lending desks is smaller than a decade ago, and the survivors tend to require a longer production history, a bank-reviewable reserve report weighted toward proved developed producing reserves, and covenant capacity to absorb a redetermination. Small operators with a short track record or a heavily undeveloped reserve base often don't fit the box yet, even when the underlying asset is sound.

Are private energy lenders more expensive than banks?

Generally yes — private and specialty energy lenders charge more than a bank reserve-based line, reflecting the extra risk and speed built into the deal. The right comparison isn't the headline rate alone but the total cost of capital: a bank rate you can't qualify for isn't cheaper than a private rate you can actually close.

Which is faster to close, a bank or a private lender?

Private and specialty lenders are almost always faster, since there's no committee credit cycle and underwriting is built around a single deal rather than a standardized program. A bank RBL typically takes weeks to a couple of months once full underwriting begins; a private facility can close in a fraction of that time when documentation is ready.

Can I refinance a private credit facility into a bank loan later?

Yes — it's one of the most common paths in the market. Use private capital to fund the stage a bank won't touch, build a production and financial track record over roughly twelve to twenty-four months, then refinance the balance into cheaper bank pricing once the asset qualifies.
