When Mexico reformed its energy sector and opened its doors for exploration, countries from around the world were eager to seek its prizes. Leading the charge for foreign investment was Sierra Oil and Gas. In this book, Sierra's CEO and co-author Ivan Sandrea have partnered with a global team of experts to tell Mexico's rich exploration history.

Mexico has large extractive industries and it traditionally has raised sizable fiscal revenues from the oil and gas sector. A confluence of factors—elevated commodity prices, financial challenges of the state-owned oil company Pemex, and revenue needs for financing social and public investment spending over the medium term—suggest that a review of Mexico’s taxation regimes for natural resources would be opportune, against the backdrop of a comprehensive approach to tackling Mexico’s challenges. This paper identifies opportunities for redesigning mining taxation to increase somewhat the revenue intake while maintaining the favorable investment profile of the sector. It also discusses recent reforms to the oil and gas fiscal regime and future reform considerations, with attention to the attractiveness of investment on commercial terms—an issue that should be placed in the context of an overall reform of Pemex’s business strategy and possibly of the energy sector more generally.

The United Nations Framework Classification for Resources (UNFC) is a project-based classification and management system applicable to all energy and mineral resource projects including renewable energy, anthropogenic resource projects as well as injection projects for geological storage. Since the adoption of the Sustainable Development Goals (SDGs), managing energy and raw material resources in a sustainable manner has become paramount to all stakeholders such as Governments, companies and investors. This has to be viewed along with the Paris Climate Accord, which seeks low-carbon pathways in the appropriate developmental strategies. Successful resource management in the modern world requires relevant information on the resource base, understanding of the factors that are responsible for progressing the resources to production, adequate framework conditions set by the regulators and society and the enterprising capacity. A series of case studies on various resource projects from different countries are presented in this report to demonstrate how UNFC could be used for sustainable resource management.
