Oil and gas assurance

External audit

EY is the auditor of some of the world’s most innovative companies. We have a wealth of experience in the unique assurance needs and circumstances of the oil and gas sector, and have developed some leading practices:

Direct audit approach: With an increased focus on efficiency and effectiveness, we’ve adopted a directed audit approach on large global audits. This centrally driven and directed approach allows our teams to focus on those areas that we’ve identified as having high risk of material misstatement.

Shared service centers: A number of our large global clients operate shared service centers in countries including Argentina, Poland, Malaysia, Philippines, UK, Ireland, India, Hungary, Indonesia and the US.

This has allowed us to develop an audit approach specific to shared service centers that enhances efficiency and reduces the audit footprint.

Mobility: Being a leader in serving the oil and gas sector has allowed us to invest differentially and build a strong network across all the key oil and gas territories. The size of EY’s global oil and gas base creates opportunities that allow us to move resources to supplement local needs.

Commodity trading: We have a dedicated commodity trading risk management team. Our in-depth experience across the oil and gas majors, global utilities, investment banks and independent commodity traders gives us an understanding of leading industry practice and the current challenges the industry faces. This gives us a full appreciation of the key risks in a trading organization and how to mitigate them, including rogue trader risks.

Other assurance services
We offer other assurance-related services applicable to companies in the oil and gas industry, such as statutory audits, Sarbanes-Oxley compliance, assessment of procedures and controls relating to privacy and confidentiality, performance measurements, systems reliability, information security and outsourced process controls.

Our teams examine processes and outcomes of non-financial risk assessments to confirm whether non-financial risks appropriate to the business have been identified and whether adequate controls have been established to mitigate these risks. We review internal monitoring and reporting mechanisms to test the adequacy of management information and internal reporting. We work to understand existing internal oversight for key nonfinancial issues, highlighting strengths and identifying potential areas for improvement.

Climate change and corporate responsibility
Issues such as health and safety, environmental impacts, social performance, ethics and human rights are critical to the commercial success of our oil and gas clients. With organizations in the sector coming under increasing scrutiny from investors, governments, regulators, communities and other stakeholders, we work with our clients in the sector to:

  • Understand and prioritize material non-financial issues and risks, develop and implement strategies, improve governance, and develop performance metrics and controls through our sustainability advisory services
  • Enhance confidence in internal management and external reporting of performance, and support the delivery of performance improvements, through a range of assurance services

Financial Accounting Advisory Services

We bring together global, multidisciplinary teams who have deep sector knowledge, to provide tailored solutions in the following areas:

  • Accounting and financial processes: Designing and enhancing accounting and financial reporting processes, preparing accounting manuals and related application guidance
  • Accounting standards and regulatory requirements: Supporting companies in implementing new accounting standards, regulations or accounting policies

  • Transactions, IPOs and financial reporting assistance: Addressing key accounting and regulatory challenges that arise on mergers, IPOs, acquisitions and divestitures, to help optimize the transaction outcome

Fraud Investigation and Dispute Services
The global nature and scale of the oil and gas sector and the complexity of the working and contractual relationships with governments, venture partners, suppliers and other contractors presents unique legal and regulatory challenges and makes compliance with anti-bribery and anti-corruption legislation something that requires significant management focus.

With stronger enforcement actions and intensified scrutiny, as well as pressure for increasing transparency of information in operations, materials sourcing and payments, companies in the oil and gas sector require assistance now more than ever to successfully navigate the legal and regulatory landscape. Our forensic practice can provide this assistance, whether it’s in relation to a dispute with a business partner, regulatory enquiry, internal investigation or even assessing the background of a prospective business partner or the legacy bribery and corruption risks of a proposed acquisition.

We can help you manage risks in your supply and distribution chains, trace and document the source of conflict minerals, quantify the value of payments to foreign governments and improve your operations to help prevent fraud, abuse and fuel loss. Our global network of professionals can quickly respond to your requirements with a team that includes oil and gas professionals in the relevant geography who understand your company, the industry and challenges of the local environment.

  • Fraud investigations
  • Forensic data analytics
