The Sab’atayn Basin is one of two key petroleum provinces in Yemen. It is located on the southern edge of the Arabian Peninsula on the south western margin of the Arabian tectonic plate in desert terrain. The production history of the basin dates back to the 1980s, when the giant Alif field was found and brought onstream by the Yemen Exploration and Production Company (YEPC) joint-venture. In 2013 a licencing round opened to new applications, aiming to generate new interest in exploration, although just three new blocks were awarded in the basin. However the deteriorating political, civil and military situation in Yemen since 2014 has effectively brought any further new licence awards or exploration work to a halt for the immediate future. because of this we have excluded an Outlook analysis. If and when the situation changes, we will re-evaluate exploration opportunities.
