In 2006, Malta and Tunisia signed a joint exploration agreement and the two countries had to map out the zones of the continental shelf were joint exploration could be carried out.
Last October, Leni Gas & Oil, one of the companies currently exploring for oil in Malta, has said that it is likely that there are around 5 billion barrels of oil in the area of exploration, of which almost 1.5 billion barrels would be recoverable.
Its latest quarterly report for 2008, the company said that no exploration work has been carried out since then, since the Maltese government is still discussing joint boundaries with Tunisia and Libya.
