Tight gas in the Neuquén Basin, Argentina

The high consume of gas in Argentina has demanded the increase of gas production and the developing of the tight gas resources. Here, we will describe the most characteristics tight gas reservoirs of the Neuquén Basin: the Mulichinco, Las Lajas and PreCuyano formations. Mulichinco`s, with permeability as low as 0.001 mD, is in early development stage and has several pilot wells planned for 2007 to better define its potential; Las Lajas`, focus of the Argentinean Tight Gas main project, produces only if hydraulic fractured, and needs new technologies to better define its sands thicknesses and trap system; Precuyano`s, with reservoirs of volcanic origin, presents a highly structural complexity and requires different fracture approach for each pay zone.
