Local Content in the Oil and Gas Sector
(Washington, DC: World Bank, 2013-07)A number of countries have recently discovered and are developing oil and gas reserves. Policy makers in such countries are anxious to obtain the greatest benefits for their economies from the extraction of these exhaustible resources by designing appropriate policies to achieve desired goals. One important theme of such policies is the so-called local content created by the sector- the extent to which the output of the extractive industry sector generates further benefits to the economy beyond the direct contribution of its value-added, through its links to other sectors. Local Content Policies (LCPs) were first introduced in the North sea in the early 1970s and ranged from restrictions on imports to direct state intervention in the oil sector. While LCPs have the potential to stimulate broad-based economic development, which is necessary to alleviate poverty and achieve the United Nation's Millennium Development Goals (MDGs), their application in petroleum-rich countries has achieved mixed results. This paper serves to introduce the topic by describing policies and practices meant to foster the development of economic links from the petroleum sector, as adopted by a number of petroleum-producing countries both in and outside the Organization for Economic Co-operation and Development (OECD). The paper is organized as follows: chapter one defines local content and briefly illustrates the links between the petroleum sector and other economic sectors (where policies may be able to increase the economic benefits of the petroleum sector). An attempt is made to measure local content levels in a wide sample of petroleum-producing countries including net importers and net exporters, and countries at different stages of economic development to put LCPs in context and to consider if the structure of an economy is a key driver of local content levels. Chapter two discusses the arguments that have been used in favor and against the use of productive development policies in general and LCPs in particular. Chapter three provides an outline of the tools and types of LCPs that have been used by petroleum producing countries, and present their strengths and weaknesses. Chapter four focuses on issues related to the measurement and monitoring of LCPs, and discusses the limitations of alternative metrics. Chapter five provides a description of LCP objectives, implementation tools, and reporting metrics used in a selected sample of oil-producing countries including Angola, Brazil, Kazakhstan, Indonesia, Malaysia, and Trinidad and Tobago and draw initial lessons that may be relevant to other countries. -

Sovereign Wealth Funds and Long-Term Development Finance : Risks and Opportunities
(World Bank, Washington, DC, 2014-02)Sovereign wealth funds represent a large and growing pool of savings. An increasing number of these funds are owned by natural resource exporting countries and have a variety of objectives, including intergenerational equity and macroeconomic stabilization. Traditionally, these funds have invested in external assets, especially securities traded in major markets. But the persistent infrastructure financing gap in developing countries has motivated some governments to encourage their sovereign wealth funds to invest domestically. This paper proposes some basic elements of a conceptual framework to create a system of checks and balances to help ensure that the sovereign wealth funds do not undermine macroeconomic management or become a vehicle for politically driven "investments." First, the risks and opportunities of domestic investment by sovereign wealth funds are analyzed. Central issues are the relationship of sovereign wealth fund financing to the budget process and to the procurement systems of sector ministries, as well as the establishment of appropriate benchmarks and safeguards to ensure the integrity of investment decisions. The paper argues that a well-governed sovereign wealth fund, with a sound mandate and professional management and staffing, can possibly improve the quality of the public investment program. But its mandate should not duplicate that of other government institutions with investment mandates, such as the budget, the national development bank, the investment authority, and state-owned enterprises. Establishing rules on the type of investment (for example, commercial and/or quasi-commercial) and its modalities (for example, no controlling stakes, leveraging private investment) is one way to ensure separation between the activities of the sovereign wealth fund and those of other institutions. The critical issue remains that of limiting the sovereign wealth fund's investment scope to that appropriate for a wealth fund. If investments that generate quasi-market returns are permitted, the size of the home bias should be clearly stipulated and these investments should be reported separately. -

Natural Oil Companies and Value Creation : Volume 2. Case Studies
(World Bank, Washington, DC, 2011-03)Approximately two billion dollars a day of petroleum are traded worldwide, which makes petroleum the largest single item in the balance of payments and exchanges between nations. Petroleum represents the larger share in total energy use for most net exporters and net importers. While petroleum taxes are a major source of income for more than 90 countries in the world, poor countries net importers are more vulnerable to price increases than most industrialized economies. This paper has five chapters. Chapter one describes the key features of upstream, midstream, and downstream petroleum operations and how these may impact value creation and policy options. Chapter two draws on ample literature and discusses how changes in the geopolitical and global economic environment and in the host governments' political and economic priorities have affected the rationale for and behavior of National Oil Companies' (NOCs). Rather than providing an in-depth analysis of the philosophical reasons for creating aNOC, this chapter seeks to highlight the special nature of NOCs and how it may affect their existence, objectives, regulation, and behavior. Chapter three proposes a value creation index to measure the contribution of NOCs to social value creation. A conceptual model is also proposed to identify the factors that affect value creation. Chapter four presents the result of an exploratory statistical analysis aimed to determine the relative importance of the drivers of value creation. In addition, the experience of a selected sample of NOCs is analyzed in detail, and lessons of general applicability are derived. Finally, Chapter five summarizes the conclusions. -

Crude Oil Price Differentials and Differences in Oil Qualities : A Statistical Analysis
(World Bank, Washington, DC, 2005-10)This report updates and extends previous work by a statistical analysis of the relationship between crude price differentials and three quality differentials, as well as transport costs and seasonal effects. In addition to the API (American Petroleum Institute) gravity number and the sulfur content of the crudes, which are the qualities generally included in existing analysis, the report presents the impact of acidity (measured by the Total Acid Number - TAN) on the price differential. This is because acidity has become increasingly important as the volume of high acid crudes, particularly from West Africa, has steadily increased in recent years. -

Experiences with Oil Funds : Institutional and Financial Aspects
(World Bank, Washington, DC, 2006-06)This study brings together detailed information on the creation, operation, and financial performance of 12 oil funds and 3 other resource funds. The report looks at various funds in Alaska, Alberta, Azerbaijan, Norway, Chad, Sao Tome Principe, Timor, Chile, Nauru, Papua New Guinea, Kazakhstan, Kuwait, Oman, Venezuela, and Russia. The purpose of the study is to provide comparative information on the backgrounds of the creation of these funds, the legislation used to do so, the details of the organization and management of the funds, and of their financial performance. The report opens with a brief review of the reasons for establishing an oil fund and the principal issues involved. The report then provides detailed coverage of four oil funds where there is substantial public information about the operation and performance of the funds. The final chapter provides some comparative material on the different funds and explores the construction of a set of indicators for good practice in the design of the funds. The appendixes contain the legislation which created the governing funds. -

Policy Approaches to Climate Change in Mineral Rich Countries
(World Bank, Washington, DC, 2019-04-29)The green economy entails an approach by nations to adopt economic policies designed to develop climate-sensitive industrial sectors that can drive long-run sustainable economic growth. Any meaningful transition to a new green economy will require the mining sector as a central stakeholder. This is in part due to the significance of the minerals sector to the overall global economy. Minerals make up and will continue to make up the fundamental building blocks of the global economy. This report provides an overview of the policies of countries leading the shift toward a green economy, and the implications of those policies for the mining sector in those countries. -

Financing Solutions to Reduce Natural Gas Flaring and Methane Emissions
(Washington, DC: World Bank, 2022-03-18)Global oil and gas emissions fell to historic lows in 2020 as a result of the decline in global demand associated with the COVID-19 (Coronavirus) pandemic. Data released by the International Energy Agency suggest that CO2 emissions are on the rise as energy demands increase after the pandemic. Whether emissions will rebound to precrisis levels largely depends on governments’ emphasis on clean energy transition in their efforts to reboot economic growth. In 2019, direct and indirect emissions from the oil and gas sector represented about 15 percent of the global energy sector’s greenhouse gas emissions. More than half of these emissions came from flaring and methane released during oil and gas operations. This book aims to create awareness of the business case for reducing gas flaring and methane emissions. It provides a framework for policy makers to evaluate the feasibility and financial attractiveness of flaring and methane reduction (FMR) projects, analyzes investment barriers, and identifies key variables and success factors, backed by lessons learned from case studies. Simplified financial modeling templates are suggested to help policy makers to assess FMR options. The book focuses on midsized flares that collectively represent 58 percent of the global flare volumes. These flares are typically too small to be prioritized by oil companies but still allow for profitable monetization. Smaller FMR projects are unlikely to be economically viable, unless clustered in larger projects or propelled by an enabling and compulsory regulatory framework. Large-scale capture projects require tailored projects, large ancillary infrastructure, government planning, and capital injections costing hundreds of millions of dollars. Although potentially attractive in terms of equity returns to developers, midsized flares face various barriers to the financing and execution of FMR solutions. Navigating these barriers requires project developers with specific FMR expertise, as highlighted through six detailed case studies discussed in this book. -

Climate-Sensitive Mining: Case Studies
(World Bank, Washington, DC, 2019-04-29)The mining industry, which provides input to almost every product and service in the world, is a critical component of sustainable growth in mineral-rich countries and the economy at large. This report is intended to deliver an account of mining technologies, processes, and strategies that seek to incorporate environmental sustainability considerations and have the potential for local value creation and green growth. The analysis focuses on three areas--renewable energy, water management, and automation and transportation--that are considered to have the broadest impact on environmental sustainability and in-country value creation through economic linkages. A reference case study is presented for each of the four benchmark minerals: gold mining in Burkina Faso, iron ore in Australia, copper in Peru, and cement in India. The report is part of a series of background reports that inform the research on Building Resilience: A Green Growth Framework for Mobilizing Mining Investment. -

Mining Firms' Climate-Sensitive Initiatives
(World Bank, Washington, DC, 2019-04-29)The need for mining firms to rethink and retool their local value creation efforts, along with the growing complexity of climate policies, presents an opportunity for forward-thinking mining fi rms to seize a competitive advantage. As this report argues, firms that systematically tackle their climate responsibilities and adapt to climate realities through technical solutions that offer scalable economic value to host nations are best placed to contribute to sustainable growth in their countries of operation.
