Joint Venture Partner or Debt: Which Capital Fits Your Oil and Gas Project?

By MercFinancial · Published 2026-08-29 · Updated 2026-09-07

Debt keeps your ownership but demands repayment from a declining asset; a partner takes part of the upside but shares the risk and funds what lenders will not. Here is how to weigh selling interest, farm-outs, carries and DrillCos against borrowing.

For an oil and gas project, debt fits when there is producing collateral to lend against and the plan is to keep the upside; a joint venture partner fits when the project is undrilled, the operator lacks the equity a lender requires, or the risk is too concentrated to carry alone. Debt preserves ownership and control but must be repaid from a declining asset on a fixed schedule. A partner dilutes ownership but shares the cost, the risk and the time, and funds the stages lenders will not touch. Most projects end up using both, in sequence.

This article sets the two routes side by side: what each gives up, the partner structures from an outright sale of working interest to farm-outs, carried interests and DrillCos, the debt structures from bank reserve-based lending to private credit, the situations where no lender will lend and a partner is the only realistic capital, how cost, control and dilution compare in general terms, and the sequences operators use to combine both without the two sets of documents fighting each other.

"I spent months trying to borrow against acreage nobody would lend on. The day I stopped asking who would lend and started asking who would drill with me, the project moved."

What Each Route Actually Gives Up

The table explains why the choice is rarely a matter of preference. Debt is the cheaper capital when it is available and the wells perform, and the harsher capital when they do not. A partner is the more expensive capital on a good well and the only capital on many projects before the first well exists.

The Partner Structures, From Selling Interest to DrillCos

Selling working interest. The simplest route: you sell a share of the leases or wells for cash and the buyer pays its share of costs going forward. It is fast and clean, and it prices the project before the wells prove it.

Farm-out. You assign part of your acreage to a partner who earns it by drilling and paying for a well, while you keep an overriding royalty, a working interest in the well, or a back-in after payout. Farm-outs convert acreage you cannot afford to drill into a well and a retained interest, at the cost of part of the block.

Carried interest. A partner pays your share of the well costs, usually through completion, in exchange for a larger share of the interest than its cash alone would buy. You give up more ownership than in a straight sale but keep exposure to the wells without writing a check.

DrillCo. A capital provider funds an agreed share of the cost of specific wells in exchange for a working interest in those wellbores only. Once it earns a target return, part of its interest reverts to you. It leaves your existing production and your acreage untouched and funds drilling that no lender would.

Drilling programs and industry joint ventures. Raising capital from a group of investors in a drilling program, or partnering with another operator under an area-of-mutual-interest agreement, spreads the risk further. Selling interests to passive investors can be a securities offering under federal and state law, so those structures are built with counsel from the start.

The Debt Structures, From Bank Reserve-Based Loans to Private Credit

Bank reserve-based lending advances against the engineered value of producing reserves under a borrowing base that is redetermined as prices and reserves change, with hedging and covenant requirements; it is the cheapest debt in the industry and the hardest to qualify for, and its mechanics are in reserve-based lending explained. Private energy lenders and credit funds make term loans and delayed-draw development facilities on smaller or younger production, at a higher cost, sometimes taking an overriding royalty or a net profits interest as a kicker. Second-lien and mezzanine debt sits behind a bank loan and prices accordingly. Equipment loans finance rigs, compressors and tank batteries against the equipment itself.

A volumetric production payment is the hybrid: you sell a defined volume of future production for cash today, with no repayment obligation beyond delivering the volumes. It behaves like debt on the cash-flow statement and like a sale in the documents. Which lender type fits which operator is covered in bank vs private energy lender.

When Lenders Will Not Lend and a Partner Is the Only Route

Lenders decline whole categories of projects regardless of how good the geology looks, because their model needs collateral that already produces. A partner is the realistic capital when the project has no producing reserves and the value is in undrilled acreage; when the wells are exploratory or the play is unproved; when the risk is concentrated in one or two wells; when the operator has no track record on offset wells; when title is not yet ready for a lender's opinion; when the deal is too small for an energy lender's minimum; or when a price downturn has shrunk borrowing bases across the market.

Operators sometimes lose months proving that no lender will fund a stage that partners fund routinely. The specific capital sources for the drilling stage are laid out in drilling and completion financing for small operators, and the acreage stage in financing oil and gas lease acquisitions.

Cost of Capital, Control and Dilution in General Terms

The cost of debt is knowable in advance: interest, fees and any kicker, paid over a defined term. The cost of a partner is not knowable until the wells have produced, because the partner's share of every future barrel is the price. On a strong well, the partner's share can dwarf what interest would have cost; on a dry hole or a marginal well, the partner absorbed a loss you would otherwise have carried alone while still owing the lender. That asymmetry is the whole decision.

Control differs in kind. A lender constrains you through covenants, hedging requirements, borrowing base redeterminations and consent rights over asset sales, but it does not vote on operations. A partner votes: the operating agreement governs AFEs, elections, preferential rights and transfers, and a partner with a large enough share can stall a program. Personal guarantees generally come with debt and not with partners. Tax treatment of drilling costs also differs by structure and belongs with your tax advisor, not with the person selling you either one.

Combining Both: The Sequences That Work

The most common pattern is a partner for the drilling and debt for the production: fund the first wells with a farm-out, a carry or a DrillCo, and once they have produced for a few months, term out the costs with a reserve-based loan sized on the new reserves. A second pattern is a sell-down to raise the equity a lender requires, so that a smaller loan closes on the rest. A third is a DrillCo on new wells alongside a bank facility on existing production, kept separate so the lender's collateral is not diluted.

Frequently Asked Questions

Is it better to borrow or take a partner for a drilling program?

Borrow when you have producing reserves to lend against and want to keep the upside; take a partner when the wells are undrilled, the equity a lender requires is not there, or the risk is concentrated. Debt is cheaper on a good well and harsher on a bad one because it is still owed. Most operators use a partner for the drilling and debt once the wells produce.

What is a carried interest in oil and gas?

A carried interest is an arrangement in which a partner pays your share of the costs of a well, usually through completion, in exchange for a larger share of the interest than its cash alone would buy. You keep exposure to the well without funding it. It costs more ownership than a straight sale but preserves participation in the outcome.

Can you get a loan for an oil well that has not been drilled?

Rarely. Lenders advance against producing reserves, and undeveloped reserves receive little or no credit in a borrowing base. An operator with existing production can sometimes fund a new well from a facility secured by the wells it already has. An operator without production usually funds the first wells with equity, a partner or a DrillCo and borrows against them afterward.

What is the difference between a farm-out and a DrillCo?

In a farm-out, a partner earns an assignment of part of your acreage by drilling a well, and you keep a royalty, a working interest or a back-in. In a DrillCo, a capital provider funds a share of specific well costs for an interest in those wellbores only, part of which reverts to you after the provider reaches a target return. A farm-out gives up acreage; a DrillCo gives up part of the early production from named wells.

Can you combine a joint venture partner with bank debt?

Yes, and most producing operators do. The usual sequence is a partner for the drilling and a reserve-based loan once the wells have production history. The documents must be coordinated: credit agreements typically require lender consent to transfer interests, and operating agreements typically give partners preferential rights, so each set of documents should acknowledge the other before signing.
