All good points. There are a lot of talented developers in Argentina, in addition to the support call center type jobs.
Is Argentina making any improvements recently on the oil and gas front from what you see?
In reality, I don't think so. Og (esp uncon) is a slim margins volume game. It requires 24/7 operations, reliability, and good planning to be profitable. Most of these requirements aren't strong suits of the local environment. You also need to create efficiencies as ways to solve cost problems, through improvements in processes and competition among contractors. Once again, not strong suits.
Without going into too much detail I think the operators that are going full out on productiln have no other options on where to invest money. That's good for them though that they're staying busy. I am not really sure how they are making money though. Those international companies that have options elsewhere in the world are choosing to minimize activities here with only completing what is necessary to hold leases and fulfill agreements.
If the gov were serious about developing these export options they would allow labor/union reform, imports (new technologies and required project materials not available in the country), and protections for foreign investments. A few months ago the health workers basically shut down the entire Neuquén province for a total of 30 days. The government did nothing to secure the roads needed to conduct production activities. If that gives you an idea of how seriously the government takes this industry.
