Oil and Gas Acquisition Financing: Producing Properties, Leases and Working Interests

Senior debt for buying producing wells, working interests, royalties and leasehold, structured with seller notes and equity so the acquisition closes and the loan still works after the first redetermination.

What lenders will finance in an acquisition

Producing properties are the easiest to finance because the lender can size the loan on proved developed producing value, the same way as a reserve-based loan. Working-interest purchases in producing wells, royalty and mineral acquisitions with established income, and operating companies with a fleet of wells all fit. Undeveloped leasehold is the hard case: a lease expires if nothing is drilled in its primary term, so lenders treat it as equity unless it comes with production or a drilling commitment they can underwrite.

How the loan is sized and stacked

A lender starts from the target's reserve report run on its own price deck, assigns most of the value to PDP and lends a fraction of it; the loan is rarely the whole purchase price. The rest of the capital stack is a seller note, the buyer's equity, and sometimes a partner. A well-structured deal closes with senior debt covering a conservative share of PDP value, a seller carry subordinated to the senior lender, and enough buyer equity that the first redetermination does not create a deficiency. We model the stack before the file goes out so the lender sees a closable deal.

What closing looks like

Expect a purchase and sale agreement with an effective date, title review on every lease, assignments and conveyances recorded at closing, transfer orders to the purchasers, and the lender's mortgage and security agreements filed in the same closing. Escrow and a brief transition period for operations are normal. The lender's engineering and title review drives the timeline, typically six to ten weeks from a complete file; a stale reserve report or unresolved title defects are the usual causes of delay.

Working with MercFinancial on an acquisition

We place acquisition loans with the private and institutional energy lenders that fund them at the deal's size, build the capital stack with you, and keep the seller-note and equity pieces consistent with what the senior lender will accept. One packaged file, two or three fitting lenders, term sheets compared like for like.

MercFinancial is a commercial funding brokerage, not a lender. Approval, loan amount, rate, term and funding are decided by the funding source on the strength of the file; nothing on this page is an offer or a commitment to lend.

Frequently asked questions

How much of a producing-property purchase can be financed?

A fraction of the lender's risked PDP value, which is itself usually below the purchase price. Buyers should plan on meaningful equity, often with a seller note in between. The exact share depends on the asset, the lender and the price deck.

Can I finance the purchase of a working interest in existing wells?

Yes. A working-interest acquisition in producing wells is underwritten on the interest's share of net revenue, and can be funded through an acquisition loan or a working-interest line, depending on size. The operating agreement, division orders and the operator's history are part of the file.

Will a lender finance a lease acquisition or lease bonus payments?

Rarely with debt alone. Undeveloped leasehold has no cash flow and expires if undrilled, so lenders treat it as equity. Leases that come with production, or an acquisition where drilling is financed alongside, can be structured; our lease acquisition guide covers the options.

How long does an acquisition loan take?

Six to ten weeks from a complete file is typical, driven by the lender's engineering and title review. Having the seller's reserve report, lease operating statements, title and division orders ready at signing of the PSA is the single biggest accelerator.
