Here are significant phrases I copied from Zion’s recent updates and press releases,
“encouraging shows of hydrocarbons” (Nov 23, 2022)
“comprehensive tests including neutron-density, sonic, gamma, and resistivity logs” (Nov 23, 2021)
“we have completed our planned logging operations” (Jan 10, 2022)
“After reviewing these logs, our third-party engineering group has recommended bringing in specialized completion liners for the next steps and for the indicated zones of potential production”
(Jan 10, 2022)
“enhancement and reservoir testing phase” (Feb 16, 2022)
“Zion continues with progress to production testing” (Apr 7, 2022)
“We are looking forward to our supervisory committee meeting with the Israeli government along with local municipalities.” (Apr 7, 2022)
“Zion’s MJ-02 well has been completed through casing, liner, and cementing” (May 11, 2022)
“Ongoing operations include well stimulation and DST testing”
(May 11, 2022)
The DST (Drill Stem Test) is the “moment of truth.”
There are five moments of truth in DST-
“Here are the five moments of truth of a DST in exploration wells,
The first moment of truth is after the DST valve is open, you begin to see air bubbles showing up in a bucket of water that is placed on the rig floor. As the air bubbles become stronger, you know something is coming out from the test interval.
The second moment of truth is when you see the fire at the burner. When you see the flare, it confirms you have found hydrocarbon.
The third moment of truth is when we know the flow rates of the hydrocarbon fluids that come out from the well.
The fourth moment of truth is after you have measured the initial bottomhole shut-in pressure and the final shut-in bottomhole pressure. Reservoir engineers will love these two pressures to be about the same. If the final BHSI pressure is much lower than the initial BHSI pressure, it may indicate the reservoir is quite small.
The fifth moment of truth is when you know the fluid composition when you receive the fluid analysis report from the laboratory. This last moment of truth may kill all the prior excitements during a DST.”

Zion is currently working on this DST testing. All things look encouraging but that 5th moment of truth seems to be the big one. Let’s see what the June 9th stockholder meeting reveals.”
