The Neuquén Basin in western Argentina offers a variety of attractive hydrocarbon plays in both the Jurassic and Cretaceous sequences. Exploration to date has proved hydrocarbon reserves of 800 million cu.m oil‐equivalent 60% of which are gas. These reserves have been found mainly in relatively small structures along the stable platform area, where good reservoir‐quality sandstones and carbonates are present. In the western thrust‐belt, large structures remain untested; however, reservoir quality in this area is a problem. The exploration dilemma is therefore. whether to search for “elephants”, with a high risk of finding adequate reservoirs, or be satisfied with the less risky but smaller rewards associated with foreland traps.
