It appearsRE: RE: SINOPEC The tidiest way to reduce exposure in Argentina is via a sale of the assets.
Sinopec need not fear nationalization by Argentina, so I expect they might be interested in the assets, as would YPF. According to the article below, ExonMobil, Chevron and Apache may also be interested in acquiring some producing assets.
If we assume the assets are worth $50,000/boe/d, and they might sell for a 25% discount or about $140mil. I doubt that GTE has that much money into Argentina, so should come close to a break even proposition
