JOINT VENTURE AUDIT SERVICES
Concession / License-Based Systems Audits
Concession and license-based systems grant contractors direct equity interests in produced hydrocarbons, with title typically passing at the wellhead. Revenue is generated through the sale of each partner’s proportional production share in accordance with its working interest. The contractual backbone consists of a Concession or License Agreement supported by a JOA and Accounting Procedure, under which costs are accumulated and allocated through a joint account. All exploration, development, and operating expenditures are funded proportionally by the equity partners, and no contractual cost recovery mechanism applies. Profit is determined at corporate level as revenue from hydrocarbon sales minus operating costs, depreciation, royalties, and taxation. The State participates primarily through royalty payments, production-based levies, and corporate income tax. Economic performance therefore depends directly on production efficiency, price realization, cost discipline, and fiscal burden.
These systems are predominantly applied in OECD-aligned upstream jurisdictions, including the North Sea basin, continental and Central Europe, North America, Australia, and parts of Latin America. They are characteristic of regulatory environments with established fiscal frameworks and equity-based participation models.
From a joint venture audit perspective, the joint account constitutes the central financial interface between partners and therefore represents the primary area of economic exposure. Audit procedures focus on verifying that expenditures are properly attributable to the venture, proportionally allocated in accordance with working interests, and compliant with the contractual cost framework.
Testing covers invoice validation, the integrity of cost accumulation, allocation methodologies, and partner billing processes. Particular attention is given to shared-service allocations, overhead mechanisms, affiliate transactions, material charges and inventory management.
Governance compliance, including adherence to approval thresholds and budget authorizations, is also assessed to ensure that expenditures reflect contractual rights and obligations.
The overall objective is to confirm that the joint account accurately represents economically justified and contractually permissible costs within a transparent and disciplined cost-sharing environment.
Production Sharing Contract
(PSC) Audits
Under a Production Sharing Contract, the State retains ownership of hydrocarbons, while contractors recover eligible costs from production through defined cost oil or cost gas mechanisms. Remaining production is allocated as profit oil or profit gas between the State and contractors according to agreed contractual formulas. Expenditures are accumulated in a joint account under detailed recovery provisions, and recovery is subject to defined eligibility criteria and contractual ceilings, with unrecovered balances carried forward. In certain jurisdictions, developments are conducted through joint venture companies formed between the State or NOC and IOCs, embedding PSC execution within a structured corporate governance framework. Contractor profitability and overall economic outcomes are therefore determined by production levels, cost eligibility, recovery timing, and production-sharing parameters.
PSC regimes are widely applied across hydrocarbon-producing economies in Africa, the Middle East, Southeast Asia, Central Asia, and selected Latin American jurisdictions. They are characteristic of environments where state ownership of resources is combined with structured contractor cost recovery and production-sharing mechanisms.
From an audit perspective, the joint account represents the central financial interface between contractor parties and the State (or NOC) and constitutes a primary area of economic exposure. Audit procedures verify that expenditures are properly attributable to the contract area, proportionally allocated, and compliant with the PSC’s cost recovery framework.
Testing extends beyond invoice validation and cost allocation to the incorporation of joint account expenditures into cost recovery statements. Particular attention is given to recoverability, ceiling compliance, carried-forward balances, and the application of cost oil and profit oil mechanisms.
Compliance with governance provisions, including approval thresholds and sanctioned work programs, is reviewed to confirm that costs presented for recovery are contractually supported.
The overall objective is to confirm that joint account expenditures are accurately recorded and properly incorporated into cost recovery statements and profit oil or gas calculations within a transparent and disciplined production-sharing framework.
Exploration & Production Sharing Agreements (EPSA) Audits
Under an EPSA, the State retains ownership of hydrocarbons, while contractors recover eligible costs from production through defined recovery tranches comparable to cost oil or cost gas mechanisms. After cost recovery, remaining production is allocated between the State and contractors according to agreed contractual sharing formulas, which may differ in structure or terminology from classical profit-sharing. The EPSA framework combines production-sharing provisions with joint operating arrangements and detailed recovery annexes, accumulating expenditures in a joint account or, in some designs, at JV entity level. In many EPSA environments, developments are conducted through joint venture companies formed between the State or NOC and IOCs, embedding execution within a corporate governance structure. Recovery is subject to eligibility criteria and ceilings, with unrecovered balances carried forward. Contractor profit derives from its allocated share of production after cost recovery and, where applicable, fiscal charges. Economic outcomes therefore depend on production levels, cost eligibility, recovery timing, sharing parameters.
EPSA-type regimes are geographically concentrated in parts of North Africa and selected West Asian jurisdictions, where production-sharing mechanisms are defined in the EPSA and executed at JV company level.
From an audit perspective, the JV company’s complete accounting and financial statements may constitute the central financial interface between participating parties and therefore represents the area of economic exposure. Audit procedures focus on verifying that expenditures are properly attributable to the contract area, proportionally allocated in accordance with participating interests, and compliant with the EPSA’s contractual cost and recovery framework.
Testing covers verification of entity-level expenditures, the classification and timing of OPEX and CAPEX, cost recoverability, and EPSA-specific entitlement calculations. Additional attention is given to the organizational structure and internal control environment, including seconded personnel arrangements, contract award processes, and inventory accumulation and management
Governance compliance, including adherence to approval thresholds and budget authorizations, is assessed to ensure that expenditures reflect contractual rights and obligations. The overall objective is to confirm that billed expenditures comply with EPSA accounting procedures, are properly reconciled to the JV company’s financial records, and that cost recovery is accurately reflected in oil and gas entitlement calculations.
Other Regimes
In addition to concession or production licence frameworks, PSC and EPSA structures, upstream activities may also be governed by technical service agreements (TSA), risk service contracts, hybrid fiscal systems, or state-dominant remuneration models. Under such arrangements, contractors typically do not obtain title to production but receive cost reimbursement and a contractually defined service fee or remuneration linked to performance metrics, production volumes, or agreed tariffs. Cost accumulation may occur through joint accounts, company-level accounting structures, or operator-managed cost pools, depending on the institutional design of the regime.
From an audit perspective, the focus shifts from production entitlement verification to the accuracy of cost reimbursement mechanisms, fee calculations, tariff applications, and compliance with contractual performance criteria.
Particular attention is given to cost allowability, service fee computation, allocation methodologies, and the integrity of the underlying accounting records supporting reimbursement claims.
Governance compliance, including adherence to approval thresholds, performance benchmarks, and contractual remuneration formulas, is assessed to ensure that compensation structures are applied in accordance with the governing agreement.
The overall objective is to confirm that reimbursable expenditures and remuneration mechanisms are correctly calculated, contractually justified, and transparently reflected within the applicable fiscal and contractual framework.
