I hope Quatro44 doesnt mind me reposting his thoughts on this thread but interesting comments from someone who has been in the industry:

They had an anomolous pressure drop during fracing : Probably the seal between the liner and the upper casing failed or fluid got past it somehow.

Tie back liner: to get round the above problem simply, and have a high pressure production string. (Note: they are expecting high pressure)

Isolation plug in liner: put in place so they can pressure test liner/casing seal to confirm problem.

Stimulation indicators: By observing the pressure changes during fraccing and the close-in pressures afterwards they can tell if the frac is succesful and the reservoir pressures are maintained etc.

All good IMHO apart from small problem with pressure drop easily fixed. Will take some while to clean up I expect, BUT they are expecting it to clean up and at some pressure, which can only mean one thing imho.
