PDVSA used to be a good company, professional and efficient. Always found them good to work with. But beginning with Chavez political idiots absolutely destroyed the company and turned it into a pathetic shell of its former self. Lots of good, experienced professional people that could managed it fled the country. Sad in a lot of ways but so typical of what happens when Leftists take over.
I worked with some PdVSA people in 1999, when Hugo Chavez was in office but he had not yet made a mess of things. Still, some were looking for the escape route, since they saw the writing on the wall. This was not just the managers and engineers, this even went down to the maintenance technicians. BTW, great people to work with.
