Abstract

Summary

The main objective of the paper is to show the results from an AVAz seismic study and the way it impacts the reservoir characterization and drilling strategy for an unconventional shale oil play in Vaca Muerta Fm, Neuquen Basin, Argentina, which holds the second largest shale gas resources and the fourth largest resources of shale oil worldwide (US Department of Administration of Energy, Kuuskraa et. al., 2013). For is the first time in YPF, the Argentinean national company, an AVAz seismic attributes is generated in order to improve the characterization of this type of unconventional plays. From the interpretation it can be said that here is a very good correlation between the stress field estimated using well log data and azimuthal seismic pre stack data. After a careful parameterization of the processing sequence, pre stack anisotropic inversion delivered enough data to corroborate de geological model and formulate a better exploration well completion scheme.The well drilled following this interpretation strategy led to a better productivity in the field.
