Zion Oil & Gas, Inc.
Zion’s vision of finding oil and/or natural gas in Israel, is Biblically inspired. The vision is based, in part, on Biblical references alluding to the presence of oil and/or natural gas in territories within the State of Israel that were formerly within certain ancient Biblical tribal areas. Zion’s oil and gas exploration activities are supported by appropriate geological, geophysical and other science-based studies and surveys typically carried out by companies engaged in oil and gas exploration activities.
