Read the two drilling RNS's26 Apr 2023 12:07
So in the initial RNS on Friday, UKOG stated that the onset of shows at 358m corresponded with drilling fluid losses.
In other words, they were loosing into a fracture.
In yesterdays results RNS (the one that actually caused the share price to fall off a cliff, not the TR-1 announcement), they said that the water recovered may possibly be derived from fractured limestones either above or below the zone corresponding to the onset of oil shows.
Well, they specifically stated that the losses coincided with the first shows, so there are no fractures above 358m.
That means that the water came from either the same zone that they lost into, or an additional fractured zone(s) somewhere below 358m but above the 400m where they stopped drilling.
So that means that either the oil - water contact is between 358m and 400m, or the limestone matrix contains oil but the fractures contain water.
If it's the former, then they are already wasting time and money in continuing to drill on, as they are in the water leg.
If it's the latter, then they are already wasting time and money in continuing to drill on, as the water production from the fracture(s) will totally overwhelm any oil production from the matrix.
BTW, nowhere in yesterdays 12:13hrs RNS does it mention drilling down to 'pools of oil', unlike one poster keeps claiming.
