There is no difference between 5" and 7" unless the TCP gun size
I think it is the only limitation
But really you can run TCP/DST string
You can put two gauges in bandle carrier to measure the downhole pressure/temp. easy
I made a TCP/DST job in Gulf of Suez

Please update us with your job

As my understanding, Conventional DST with 5"OD and 2.25" ID. for 7" liner or 9 5/8" casing.

in relation to 5" cased hole, could anyone advise if we have smaller DST tools and retrievable packer to test in 5" cased hole.
