The Production Sharing Agreement (PSA) is the most widely used host government contract in the oil and gas industry, and is becoming the leading choice for most countries in their relationship with International Oil Companies (IOCs). However, there are many jurisdictional variations, and being aware of and understanding these is crucial for oil and gas practitioners working in this space.

This title is the first comparative treatment of this topic and provides a comprehensive, in-depth overview of Production Sharing Agreements in key oil and gas jurisdictions around the world. It offers a rich, critical analysis and evaluation, and features contributions from an international group of leading experts and academics who address the legal, economic and political aspects of PSAs. It also provides guidance on key recent developments by looking at jurisdictions’ overall regulatory framework and their relationship with the PSA.

This edition covers jurisdictions worldwide, including:
•Brazil;
•Indonesia;
•Kazakhstan;
•Nigeria; and
•Russia

Production Sharing Agreements: A Global Legal Handbook will be of interest to practitioners, academics and anyone who is involved in these contracts. It provides readers with a clear understanding of PSAs in different jurisdictions, and a variety of practical recommendations and takeaways.
