As previously announced on September 17, 2007, Zion signed an agreement with the Geophysical Institute of Israel to conduct one of the largest and most comprehensive geophysical surveys on-shore in Israel of the past two decades aimed at selecting the optimal drilling site for a test well on its Ramot Menashe (Menashe Heights) prospect and upgrading the company's Nahal Me'arot lead (nearby the Asher-Atlit No. 1 well) into a drillable prospect.

Zion Oil & Gas, a Delaware corporation, explores for oil and gas in Israel, onshore between Tel-Aviv and Haifa. It currently holds a 78,000 acre exploration license, known as the Asher-Menashe License, located between Caesarea and Haifa. Its application for the issuance of an 85,000 acre exploration license, tentatively named the Joseph License, located between Caesarea and Netanya, on which the company drilled a 15,842 foot well in 2005, is currently pending before the Israel Petroleum Commission. A decision on the application is expected during September or October 2007.
