Zion Applies for New Exploration License in Megiddo-Jezreel Valley Area,

DALLAS and CAESAREA, Israel, April 18, 2013 (GLOBE NEWSWIRE) -- Zion Oil &
Gas, Inc. ("the Company or "Zion") (Nasdaq:ZN) announced today that, on April
16, 2013, Zion submitted to Israel's Petroleum Commissioner and other Ministry
officials an application seeking a Petroleum Exploration License in the
Megiddo-Jezreel Valley area, onshore Israel, covering an area of approximately
98,000 acres. As proposed, the Megiddo-Jezreel Valley license area boundary is
adjacent to and westward of Zion's existing Jordan Valley License No. 393,
which covers approximately 56,000 acres. If granted, the new Megiddo-Jezreel
License would likely be for an initial three-year term with options to extend
the license annually up to seven years total.

In addition, on April 10, 2013, Zion also submitted to Israel's Petroleum
Commissioner an application seeking a one-year extension for its existing
Joseph License No. 339, which covers approximately 83,000 acres.

Victor G. Carrillo, Zion's President and Chief Operating Officer, said today,
"Submitting our Megiddo-Jezreel Valley license application is a very important
step for Zion's future exploration efforts. This is but a first step in a long
process before we can initiate our first exploratory well in the new license
area but we look forward to getting to that point as expeditiously as
possible. We thank all of our dedicated and loyal supporters."
