Pulling old carbon steel tubing

Hi all

I'm trying to get a feel for the difficulties experienced when pulling old carbon steel tubing and clamps from 30 - 40 year old wells, some of which have been shut-in for most of that time, some of which have been producing / injecting for that period. 

Particularly interested in the time taken to pull and fish the tubing (severed at top packer depth), clamps and control line with an idea of the %age of wells this time applies to if you have more than one well's experience.

(I'm reasonably content with experience of 15% Cr tubing strings although your experience of clamp retrieval with Cr pipe is also of interest in terms of age.)

Much obliged.
