* Pre-drill interpretation of the seismic showed several high-porosity intervals in MOU-5. We now know that a salt layer (of as yet unknown thickness) has resulted in these being lower than anticipated.
* I have previously presented detailed calculations on this BB based on the relative seismic s-wave transmission speeds through salt and dolomite. My conclusion was that even with a massive 150m thickness of salt (PG said the salt made a 'subtle' difference to where they intersected the structure) there would still be around 70m of carbonate higher than the gas-charged carbonate intersected in MOU-4, which had excellent porosity.
* Borehole TAF-1X intersected 18m of gas-charged dolomite with a not-very-exciting 8% porosity (Tendrara also has 8%). This was drilled several km away from MOU-5 into a different formation and off-structure, so is not representative of what is likely to be at MOU-5. Nevertheless, this was several hundred metres lower than the carbonate reservoir in MOU-4 & MOU-5. Hint – gas rises.
* Based on the above, there is a reasonable expectation that the carbonates intersected in MOU-5 should be gas bearing.
* Unlike any other drill announcement I have ever seen for any company, the RNS of 17 March 2025, and subsequent announcements and videos, made absolutely no mention of either the presence or absence of hydrocarbons, nor any indications of depths. This is so unusual that there must be a very good reason. However, we were told two important and relevant pieces of information.
“The MOU-5 well has been suspended to allow for a re-entry at a later date” - there is no way that would be done for a duster.
“Good quality resistivity and sonic wireline logs were acquired over the top 50 meters of the Domerian carbonate.” As part of previous wells' wireline logging, the following parameters were measured in addition to sonic & resistivity: Dielectric, NMR, Neutron Density Separation, Gas samples. So why mention only those two? Could it be that sonic tells you the porosity of the rock, and resistivity will tell you if those pores are filled with water, gas or oil? You would not select out just these two parameters in the above RNS statement without good reason.
* My conclusion is that by 17th March they knew exactly what had been found, but there is a reason why that has not been revealed. The usual suspects (a term from a film set in Morocco 😋) will tell us that is because there is nothing to announce. I believe that they are wrong, and GRH's tweet today is much more likely to represent the real reason for silence.
