16" hanged off in 22" casing. Anyone burst of that ?

I hadn’t seen this before that the 16" was hung off inside the 22"!!! This means that they drilled all the way to TD with approx 160ft of 22" exposed below the mud line!!!
Burst of 22"… around 4500psi possibly… Collapse rating approx 2500psi. I don’t have the exact data.
