Flow test results extrapolation16 Apr 2025 13:37
Hi
After much deliberation since the flow test result, I have a couple of questions for the board based on my limited knowledge of the industry if I may. Please take them as intended, genuine questions to help me to understand the implications of the latest result on the potential resource base for Pantheon.
The flow test of TS1 is obviously disappointing, but given the comment that the oil shows were 'a transition zone' does this effectively mean that the oil has migrated elsewhere? In other words, there was not an effective seal for this zone so the zone is water charged rather than oil. If that is the case, on the assumption that the oil source is still good, does this not raise the likelihood of the higher level zones being oil charged? Given the oil could simply have migrated upwards, leaving water behind in this lower zone, until it hits an effective trap? If this is correct, what are the seals for the next zones? Do we have any more or less confidence in those or do we simply not know at this stage? Presumably, seal is now the greatest geological risk for the remaining five zones, is that a reasonable assumption?
Secondly, what are the implications of the 'high-pressure pumping equipment' being brought in? This to me sounds positive. They expected 200bopd from TS1 but reached a steady 1000, albeit of water. With increased permeability and porosity further up the well, they expect better flow rates to improve. Has the base line moved up from the 200bopd to a higher figure because of this result (independently of the the better perm and por)? Tied in with my first question, if the oil has migrated upwards, the next zone could well be in pressure contact to this water aquifer, could this provide a decent stimulous to flow rates?
The above sounds pretty positive to me, and perhaps explains this quote in the RNS: " the data we gathered leaves us with increased confidence in the five shallower and more productive horizons that remain to be tested.".
Thirdly, I believe we had the VAS readings across these zones that indicated oil. Does this mean that VAS is picking up false positives from this transitory oil? If so, does this reduce our confidence in VAS readings across other zones? And if so, could this not also be happening in the other parts of Aphun, or even Kodiak? I guess what I am asking is whether there could be similar positive VAS readings across the whole of the 1.6bn resource that are also slightly higher risk now? Presumably the independent experts will also have used the VAS data in their evaluation and confirmation of the 1.6bn boe resource, so would they have come to the same conclusion now we have this possible false positive?
Probably too many questions for a single post, but thought I would fire away while I am here. I am a long time lurker here, I don't post much because I have little to add other than opinion. And we want to keep this a fact based board! :)
Thanks in advance for any help
