Exactly,

The longer this takes, the more there is to interpret,

No flow does not take a long time to figure out.
No oil is very simple to analyse when you have good logs.
No porosity has no mitigation, therefore does not need much analysis.

So this only leaves:

Massive reinterpretation being undertaken of the well data
possible testing mishap, does not change the well characteristics and is being overcome.
Discovery of an ancient Dwarvian kingdom, who have confiscated the sleeves and holding it for ransom.
Possible UFO uncovering, causing a mutagenic plague taking over the rig and will result in the loss of all mamallian life within the next 2-3 years.

All the of the above have equal probability until the next announcement.
