From  [HERE] Israeli investors had reason to celebrate last month with the news that Israel may soon be joining the club of oil-producing states, in addition to its recent finds of large natural gas deposits off the coast.

Shares in Givot Olam, an Israeli oil exploration company, rallied on reports that it had located much larger oil reserves at its Meged 5 site than previously estimated.

The company, which says it has already sold $40m worth of oil since the Meged field went operational in 2011, now believes that the well is sitting on exploitable reserves of as much as 3.53 billion barrels - about a seventh of Qatar's proven oil reserves.

Only one cloud looms on the horizon. It is unclear how much of this new-found oil wealth actually belongs to Israel. The well sits on the so-called Green Line, the armistice line of 1948 that formally separates Israel from the occupied Palestinian territories.

According to Palestinian officials, Israel has moved the course of its concrete and steel separation wall - claiming security - to provide Givot Olam with unfettered access to the site, between the Israeli town of Rosh Haayin and the Palestinian village of Rantis, north-west of Ramallah.
