PRESS RELEASE
Zion Oil & Gas Operational Update on Megiddo-Jezreel #1 Well in Israel

Zion to commence testing expanded zone of interest


DALLAS and CAESAREA, Israel, June 19, 2018 - Zion Oil & Gas, Inc. (NASDAQ: ZN) announces that it expects to commence perforation, stimulation and flow back operations on multiple stages of its Megiddo-Jezreel #1 (MJ #1) well as early as June 21, 2018.

Zion’s President and Chief Operations Officer, Dustin Guinn, explains Zion’s current testing operations, “As I have mentioned in previous announcements, the next two zones, the second and third primary testing objectives, are key zones of interest.

“We had originally planned to test the zones independent of one another, but both the proximity of the zones and downhole condition considerations have led us to change our strategy and combine these zones to test them simultaneously.

“While it has added a few days to properly plan for the logistics of this change with our service providers, we believe that these changes will provide the best opportunity for success in two of the zones that from a log analysis perspective identify some of the most encouraging criteria for production.

“Barring any unforeseen mechanical issues, we expect to complete the perforation and stimulation next week, after which we will monitor the well before proceeding to additional zones of interest.

“We recognize the keen interest in the MJ #1 well from not only our shareholders and the various Israeli regulatory agencies, but from many people who simply have strong feelings about Israel.

“As such, we treat this project with the utmost diligence, balancing a sense of urgency for results while continuing to insist on a zero tolerance policy regarding health, safety, security and environmental incidents.

“Management’s job is to provide long-term shareholder growth. Ultimately, that’s by finding and producing commercial amounts of oil and/or natural gas. Releasing partial or incomplete testing result information only drives short term speculation which is harmful to our long-term shareholders.

“Therefore, we will not be releasing any information, other than operational updates, until we have concluded the initial testing and analyzed the results of the primary targets at a minimum.

“This should take weeks, not months, unless unexpected mechanical issues arise.

“We want to continue to thank all of our loyal shareholders who have made this project a reality and ask that you continue to pray for success and safety in helping Israel become energy independent, giving Zion a huge platform to share the gospel of Jesus Christ.”
