What Is a Production Sharing Agreement – And How Does It Actually Work in Oil & Gas?

Core Components of a Production Sharing Agreement

Although every PSA is negotiated individually, most agreements contain several core provisions that define how exploration activities are conducted, how production is shared, and how commercial risks are allocated between the parties.

Key components include:

• Parties Involved: A PSA typically involves the host government (or national oil company) and one or more private oil and gas companies acting as contractors responsible for exploration, development, and production activities.
• Cost Recovery (« Cost Oil ») and Profit Sharing (« Profit Oil »): The contractor first recovers eligible exploration and development costs through cost oil. The remaining production—known as profit oil—is then divided between the government and the contractor using a pre-agreed sharing formula.
• Royalty Agreements: Some PSAs require contractors to pay royalties before production sharing begins, while others incorporate royalty obligations into the overall fiscal framework depending on local legislation and contractual structure.
• Work Commitments: Contractors commit to defined exploration programs, such as seismic surveys, exploratory drilling, appraisal activities, or minimum investment obligations, within specified timeframes.
• Domestic Market Obligations: Governments may require a portion of produced oil or gas to be supplied to the domestic market to support national energy security or local economic development.
• Decommissioning and Asset Ownership: The agreement establishes responsibilities for decommissioning wells, production facilities, and related infrastructure at the end of the project’s life. Ownership of assets often transfers to the state upon contract expiration.
• Dispute Resolution Clause: PSAs typically include a comprehensive dispute resolution mechanism covering governing law, arbitration procedures, and jurisdiction to resolve commercial disagreements efficiently while minimizing operational disruption.

Together, these provisions establish the commercial, operational, and legal framework governing the entire lifecycle of an oil and gas project.

Production Sharing Agreement Example: A Real-World Walkthrough

A practical example helps illustrate why production sharing agreements have become a preferred contractual model in many emerging energy markets.

Consider a country in East Africa that has identified promising offshore oil reserves but lacks the capital, deep-water drilling technology, and technical expertise required to develop them. Rather than financing the project directly, the government enters into a Production Sharing Agreement with an international energy company.

Under the agreement:

1. The government grants exploration rights while retaining ownership of the petroleum resources.
2. The international operator funds exploration and drilling using its own capital and assumes the risk that no commercially viable discovery may be made.
3. A commercial discovery is confirmed, and the operator invests in field development, production facilities, and supporting infrastructure.
4. Oil production begins, allowing the company to recover approved exploration and development costs through cost oil.
5. The remaining production is shared between the government and the operator according to the agreed profit-sharing formula.

This arrangement benefits both parties. The government attracts foreign investment, advanced technology, and operational expertise without assuming exploration risk, while the contractor gains access to valuable reserves and the opportunity to recover its investment if the project succeeds.

Similar production-sharing agreements have been used across Africa, Southeast Asia, and other resource-rich regions to support offshore exploration, encourage technology transfer, and accelerate the responsible development of national energy resources.

How Does a Production Sharing Agreement Work?

Although every PSA is negotiated individually, most agreements follow a similar commercial lifecycle that balances risk, investment recovery, and revenue sharing between the government and the contractor.

The process typically unfolds as follows:

A defining feature of a PSA is the distinction between cost oil and profit oil.

• Cost oil is the portion of production allocated to the contractor to recover eligible exploration, development, and operating expenses. Many PSAs also establish annual limits on the percentage of production that can be used for cost recovery.
• Profit oil represents the remaining production after approved costs have been recovered. This production is shared between the government and the contractor according to percentages defined in the agreement.

The government plays the role of resource owner and regulator, granting exploration rights, approving development plans, and monitoring compliance with contractual obligations. The contractor, meanwhile, bears the upfront financial and operational risk by funding exploration and managing day-to-day field operations.

Importantly, the production split is negotiated before the project begins and may vary based on factors such as production volume, oil prices, project profitability, or cumulative investment. This flexibility allows PSAs to balance investor returns with national resource interests throughout the life of the project.

Production Sharing Agreement vs. Concession Agreement: Key Differences

Production Sharing Agreements and concession agreements are both widely used in the upstream oil and gas sector, but they differ significantly in how ownership, financial risk, and production revenues are allocated.

Both contractual models can support successful oil and gas development. The choice typically depends on a country’s legal framework, fiscal objectives, investment strategy, and desired balance between resource sovereignty and private-sector participation.
