How many of those hours were spent doing pipeline patrols or other

I have only ever seen pipeline patrol being done by high wing aircraft -
never a Cherokee.

IIRC A couple of the cherokees that had wing spar failures which lead
to the (short-lived) wing spar AD were high time aircraft previously
involved in pipeline patrols. I realize that high wing aircraft are
have better visibility for such patrols.
