I think you will find its the completion packer not the actual tubing that has caused the issue as the completion packer was intended to be set around the HCSS.
The question now is because of this do they have to flow all three levels together?
Any techo's have a view on this?
Norwest Energy (ASX:NWE): On 22nd August the Company reported that operations at Arrowsmith- 2 had recommenced with the plan to drill out the remaining bridge plugs and to isolate the High Cliff Sandstone (HCSS) interval from the other zones with a completion packer.
It was expected to take approximately three weeks to complete this phase of operations.
During this period it was planned that 2 3/8” tubing would be run from surface to the installed packer, and the HCSS interval would be flowed back in isolation for a period of 2-3 weeks. This would be followed by extended flowback of the Carynginia Formation and Irwin River Coal Measures.
Operations proceeded to plan and by 6th September 2013 installation of the completion packer had commenced, however during operations it became apparent that the packer could not pass the depth of 2646m. As a consequence, it was decided to set the packer at this depth, and to adjust the forward plan accordingly.
