“Shale typically serves as a cap rock to prevent escape of fluids”.

This would be consistent with finding oil trapped lower down, based on this basic research.
A shale formation of any size would prevent fluids from rising higher.
I’m no expert and look forward to hearing from some of you who know what you’re talking about, but at least it’s possible that drilling successfully through the shale formation would mean they are tracking towards a fluid trap. Oil is a fluid, right? Maybe a tad bit of hopeful thinking.
