Joint operating agreements in oil and gas

Almost every oil and gas field of any size is shared, to spread risk and capital. The joint operating agreement, often based on an industry model form, is the contract that makes this work, and its terms drive the accounting for every partner. This guide explains why most agreements are joint operations, how the operator and the other partners record costs and cash calls, how lifting imbalances are handled, who recognises leases the operator signs, and how farm-ins and changes in interests are accounted for.

Short answer

Joint operating agreements set the rules for partners who share an oil or gas licence: each partner's percentage interest, the operator who runs the field day to day, how costs are shared through cash calls, and how production is lifted. Under IFRS 11 they are usually joint operations, because the partners have rights to the assets and obligations for the liabilities directly. Each partner therefore records its share of the field, costs and decommissioning provision, and its own sales of its own share of production. In this guide's example, an operator with a 40% interest that spends US$ 250 million on the field records only 100 million as its own, and 150 million as due from its partners.

Key facts at a glance, as set out in this guide.

What is a joint operating agreement?

A contract between the holders of a licence that sets out each party's participating interest, appoints one party as operator, establishes an operating committee to approve work programmes and budgets, and contains an accounting procedure for charging costs to the partners. It also covers what happens if a partner defaults on a cash call, how partners may decline to join a project, and how each party takes its share of production in kind.

Most licence partnerships are joint operations.

Usually, yes. Most agreements are not structured through a separate company: the partners own undivided interests in the licence and facilities and are each liable for their share of costs. That makes the arrangement a joint operation if the partners have joint control, meaning key decisions need the unanimous consent of the parties that collectively control the field. Where decisions can be passed by different combinations of partners, there is no joint control, but each party still accounts for its share of the assets and liabilities if it has rights to the assets and obligations for the liabilities. See joint arrangements in construction and mining joint arrangements for the same analysis in other industries.

How does each partner account for its interest?

Each partner records its share of the field's assets, such as wells and facilities, its share of liabilities incurred jointly, such as the decommissioning provision, its share of costs, and its own revenue from selling its share of production. There is no single set of joint venture accounts to consolidate: the operator keeps joint account records, and each partner books its share from the operator's monthly billing statements.

Joint operating agreements: the operator's books

A field has three partners: the operator with 40%, and two partners with 30% each. In a month the operator pays US$ 200 million of development costs and 50 million of operating costs on behalf of the joint operation.

US$ millionOperator (40%)Each other partner (30%)
Development costs: field asset8060
Operating costs: expense2015
Cash paid to suppliers250None
Receivable from partners, until cash calls are paid150None
Payable to the operatorNone75

The operator does not report the full 250 million as its own assets and costs: the partners' shares are amounts it is owed. In practice, operators usually call cash from partners in advance, so the operator more often holds a liability for cash received before it is spent. Receivables from partners are financial assets, subject to expected credit losses, which matters when a partner is in financial difficulty.

How are overlift and underlift accounted for?

Partners take their oil in kind, usually in full tanker cargoes, so in any period one partner may lift more than its share and another less. In this example, the field produces 1,000,000 barrels in a year. A 30% partner is entitled to 300,000 barrels but lifts and sells 350,000 barrels, an overlift of 50,000 barrels.

The partner recognises revenue on the 350,000 barrels it sold to its customers, under IFRS 15. The 50,000 barrels it owes its partners are an overlift liability, typically measured at market value, US$ 3.5 million at $70 a barrel, with the charge in cost of sales so that profit reflects its entitlement. The underlifted partners record a matching asset. Some companies measure imbalances at production cost instead; the policy should be disclosed and applied consistently. See overlift and underlift for both measurements side by side.

Who recognises leases signed by the operator?

Operators often sign contracts for drilling rigs, vessels or offices in their own name for the joint operation. The IFRS Interpretations Committee confirmed in March 2019 that a joint operator recognises the liabilities it has incurred, including its share of any liabilities incurred jointly. If the operator alone is the lessee and primarily responsible for the payments, it recognises the whole lease liability and right-of-use asset under IFRS 16, and then considers whether its arrangement with the partners is a sublease or a recharge of costs. The other partners recognise a lease only if they also have obligations under it. See identifying a lease.

How are farm-ins and changes in interest handled?

Buying an interest in a joint operation that is a business is accounted for using the principles of IFRS 3, including recognising goodwill and deferred tax, while buying an interest in assets that are not a business is an asset acquisition. Exploration-phase farm-ins, where the incoming partner pays some of the existing partner's costs in exchange for a share, are commonly accounted for without a gain by the farmor; see IFRS 6 exploration and evaluation. When a partner defaults, the others may take on its share of costs and of the field under the agreement's forfeiture terms.

How does US GAAP compare?

US GAAP permits proportionate consolidation for undivided interests in oil and gas properties, so the result is similar: each partner records its share of assets, liabilities, revenue and costs. See decommissioning provisions and oil and gas accounting.

Questions people ask

Is a joint operating agreement a joint venture under IFRS 11?

Usually not. Most are joint operations, because the partners hold undivided interests with rights to the assets and obligations for the liabilities.

Does the operator record all the costs of a joint operation?

No. It records only its own share; the partners' shares are receivables until their cash calls are paid.

How is overlift accounted for?

The overlifting partner recognises revenue on what it sold and a liability for the barrels owed to partners, often at market value; underlifted partners record an asset.

Who recognises a rig lease signed by the operator?

The operator recognises the full lease if it alone is the lessee and primarily responsible; it then assesses whether its arrangement with the partners is a sublease.
