Farmout

A farmout is an agreement under which an owner of exploration or production rights transfers or agrees to transfer some or all of those rights to another party in exchange for specified development work. It is common in oil and gas.

The original holder is the farmor and the party performing the agreed work is the farmee; the contract determines the interests earned and obligations retained.

From the Money Master HQ dictionary, founded by Shihan Sheriff (FCMA, VP of Finance at Nomod, CFO at Esanjo Ventures). How these definitions are written.

What it means

Owning rights to acreage does not mean a company has the money or technical resources to develop it, since drilling can require substantial spending before any commercially useful production occurs. A farmout allows another party to contribute the work needed to develop the opportunity.

The farmee seeks an interest it does not already own and undertakes agreed activities such as drilling, testing or reworking wells in return, and the interest may be earned only after particular conditions are satisfied, rather than transferred unconditionally on signing. The farmor can reduce its direct development burden while retaining some potential benefit, since it may keep an interest, receive an agreed royalty or have another negotiated right, though none of those features should be assumed without reading the actual agreement.

A farmout is more specific than ordinary outsourcing, because a service contractor may drill for a fee without earning an ownership interest in the resource rights, whereas in a farmout the exchange links work obligations with a transfer or earning of rights. Define the work programme, as parties can specify the location, depth, timing and standards for a well or other activity, and a vague development promise can leave disagreement over whether the farmee earned its interest.

Success in performing the work and success in discovering economic reserves are different questions, because a farmee can meet the contractual drilling requirement without finding a commercially attractive resource. The agreement should identify what result is required for earning, rather than letting those questions blur together.

Costs also need allocation, since the farmee may carry some development spending but later operating costs can follow a different sharing arrangement, and a percentage of ownership is not necessarily the same percentage of every cost at every stage. Some contracts provide a back-in after payout, under which the farmor can acquire or resume a defined working interest after specified costs have been recovered.

The timing, cost definition and election requirements depend on the contract, and the feature is not inherent in every farmout. A royalty and a working interest are different economic rights, as a royalty can provide a share of proceeds under its terms while a working interest can carry development or operating responsibilities, so comparing their stated percentages without comparing cost obligations can produce a misleading value comparison.

Approvals and underlying title matter, because the parties need to establish that the proposed transfer is permitted under the applicable rights and regulatory framework. A private agreement cannot safely assume away required consent or restrictions affecting the acreage.

Operational and environmental responsibilities need attention as well, since sharing financial exposure does not automatically remove liabilities associated with the project, so define operator responsibilities, insurance, reporting and the handling of a failed or abandoned development programme. For a non-finance manager, review the farmout as a conditional exchange rather than free development funding.

Identify what is earned, what must be done, which costs are carried and what remains afterward. Compare the retained upside with the rights given up and the risks that the arrangement does not eliminate.

In practice

Real-world examples.

1

Example

A rights holder cannot fund a test well and offers a farmee an interest if it completes the specified drilling program. The farmee budgets the work before accepting. The farmor's retained interest is defined separately from the farmee's earned interest.

2

Example

A service company drills for a fixed fee but receives no resource rights. That contract is not treated as a farmout merely because work is outsourced. The commercial exchange is a service fee, not an earned project interest.

3

Example

A farmor has a back-in option after an agreed payout calculation. The parties review which costs enter that calculation before deciding whether the condition is met. A general statement that the project is profitable does not establish contractual payout.

Formula

Calculation

Illustrative earned interest: a farmee that earns 60% of a project leaves 40% with the farmor on that stated basis. If later operating costs are shared in those proportions, a $1,000,000 eligible cost would allocate $1,000,000 x 60% = $600,000 to the farmee and $1,000,000 x 40% = $400,000 to the farmor. This is not a universal farmout formula: carried costs, royalties, payout and other terms can alter the economics.

Case study

Seen in the real world.

Fictional case: A small explorer agrees to transfer an interest after drilling but leaves the required testing work unclear. The parties disagree over whether the interest was earned when the well is completed. A revised agreement defines the work, evidence, deadlines and cost allocation so operational completion can be distinguished from commercial discovery.

Watch out

Common mistakes.

  • Confusing a farmout with fee-based drilling services.
  • Assuming earned ownership percentages match every stage of cost sharing.
  • Ignoring earning conditions, approvals and retained project liabilities.

Questions

People also ask.

Does the farmee always find commercial reserves?

No. Performing work does not guarantee an economic discovery.

Is a back-in option automatic?

No. It requires an agreed contractual mechanism.

Does a farmout remove all farmor risk?

No. Retained interests and obligations must be reviewed.
