Not really. VZ oil production peaked in 2012, long before the sanctions.

Completely dishonest answer. Sanctions decimated Venezuela's ability to maintain its oil infrastructure. Everything, from machined parts, to the various chemicals needed, everything, was affected.

It just took a few years for the sanctions to bite, as the Venezuelans conserved & used stockpiles.

Again, a completely dishonest take. Speaks volumes, when most defenders of todays criminality keep spouting arguments to this effect.

Venezuelan oil production was cratering years before the first oil sanctions because they replaced everybody who knew how to drill oil with loyalists. I didn’t realize this was debatable.

Replacing all competent but ideologically unreliable people by reliable but incompetent people got more to it. See "Politicization" in https://en.wikipedia.org/wiki/PDVSA?wprov=sfla1
