Ann: Lockyer Deep-1 Operational Update, page-42

All should be good if the top of the cement in the annulus is above the top of the main Kingia reservoir .
The set cement stops any further formation damage from the drilling fluid .
However if the top of the cement is below the Kingia then formation damage could be occurring .
To keep the well safe they will be topping up the annulus as mud filtrate moves into any open permeable zones and the mud filter cake thickens .
There is no chance to do a wiper trip to condition the hole before the remedial cement job so the cement job may not be optimal .
However if the Kingia is already protected by cement it may not matter much .

STX say the reason the flow rate test on WE5 was less than it should have been was because of formation damage .
They said they had a skin effect and blamed it on a cementing problem .

The remedial cement job will not be a squeeze .They make a hole in the casing at the level of the top of the cement in the annulus and more or less do a normal cement job .
The annulus will be open not closed .

The mechanical problem that caused this mess is not common and really does not have a lot to do with it being a deep hole .
