Rafi Oil, a subsidiary of Union Grand Energy (Singapore), operates the Surakhany field. It lies onshore Azerbaijan, around 14 kilometres northeast of Baku. The field is mature, with current production far below historical levels. Redevelopment work in the 2000s resulted in output recovering to over 4,000 b/d by 2013. However, production has been in decline ever since.The majority of crude is exported. Small volumes of associated gas are delivered to SOCAR free of charge.
