Petroleum Mass-Balance of the Neuquén Basin, Argentina: A Comparative Assessment of the Productive Districts and Non- Productive Trends* (original) (raw)

2005

Abstract

Summary The effort of eight decades of exploration and development in the Neuquen Basin (westcentral Argentina) has identified a EUR of 9.7 BBOE, with a current daily production around 360 MBO and 2.6 BCFG. As result of the de-regularization and privatization process during the 90’s, the oil and gas reserves increased within the relatively mature productive tracts (Figure 1), where the known plays contain around 1.9 BBO and 17.5 TCFG of proven and probable reserves. Additional reserves are expected from testing new play concepts outside the areas under production, as well as from future activities in the under-explored fold belt and from the eastern margin of the basin (on the Pampean foreland). Focus of Study This work focuses on a quantitative comparison of the known productive districts by analyzing the geological elements and the processes involved in the charge, migration, accumulation, and preservation of hydrocarbons. The quantification of the generationaccumulation efficienc...
