It appears that Apache just sold its Argentine assets to YPF for $800 million.
The thing to keep in mind is that this isn’t Apache fleeing an unpredictable Argentine government. Apache has been selling assets all over the world. The company is focusing back home in North America and only keeping overseas assets that are currently spinning off large cash flows. The Argentine plays were not in that category: they will require large-scale investments to develop. Moreover, unconventional fields require large continuing capital investments and often begin to decline rapidly. That is the sort of production profile Apache wants to avoid. (Although it should be mentioned that the company CEO mentions Argentine politics at the link.)
Moreover, other companies are entering Argentina. Despite the political uncertainty, the promise of tight oil is too good to avoid.
We may, however, get some more details of just how good Chevron thinks that promise is. A provincial court ordered the Neuquen government to release the details of the Chevron-YPF contract. The provincial government has appealed the decision. I doubt that we will find anything, and I doubt that there is anything interesting to find.
