I copied the below from a reddit posters (GeodesRock49) analysis of the 88e operational update, he appears to have subject knowledge and a respectful following in the US.

My concern is on interpretation, as there is a logical mismatch, between the posters conclusion and the 88e update
Bright white fluorescence indicates 40-45 API oil, which is at the light end, (agreed no problem there)
Light oil is a further step towards the condensate gas range and as such has more volatile ends, the lighter the oil the more associated gas it holds.
When there is an oil show, there is also a gas release as there is gas dissolved in the oil. The gas separates from the oil, as it depressurises, as it rises up the well from reservoir pressure to surface pressure.
Logic determines that if you have a light oil which contains a greater proportion of associated gas than a heavier oil does. As the quantity of oil increases, so will the quantity of gas.
88e state, Mud gas peaks were also recorded and, although generally not of the same scale of the increase in total gas above background as that seen in the Analogue Wells,
The gas and oil shows are proportional, a low gas show also means less oil. Confirmed here, one of the prospective horizons in Merlin-1 did have substantially elevated total gas, similar to that in the Analogue Wells.
In summary of all the multiple interval oil shows, only one of them is potentially an analogue to willow, the feet of pay in this zone is the unknown. There were three target zones being drilled, so if only one of three is potentially an analogue the prize is much smaller. The fact that all the other shows were not in the same scale is the concern/negative that this poster did not see
I CANNOT FIND ANY NEATIVES IN THE 88 ENRGY REPORT - very encouraging .

2.) Update - Details
Oil shows were recorded over multiple intervals in the Nanushuk while drilling Merlin-1, including the primary targets. Fluorescence ranged from relatively weak to moderate “dry” fluorescence with slow to moderate sometimes fast streaming cut when exposed to solvent (see Fig. 1). Mud gas peaks were also recorded and, although generally not of the same scale of the increase in total gas above background as that seen in the Analogue Wells, one of the prospective horizons in Merlin-1 did have substantially elevated total gas, similar to that in the Analogue Wells. Heavier gas components, including C5, were observed over multiple intervals. Resistivity was elevated over these intervals and is encouraging, particularly in the context that the Nanushuk is considered a low resistivity play type.
The mention of oil shows were from the Hydrocarbon Mud-Logs. The description and images in the update are identical with to examples I posted as to description and evidence. The Bright White fluorescence seen in the images is indicative of a very high quali
