More than 600 wells have been drilled from 2010 to date, in order to define the area of interest and play types of the Vaca Muerta Formation, to outline the different thermal maturity windows and to acquire critical information for its best characterization. In the last two years, the drilling of horizontal wells have started, as well as pilot and development projects to prove its productivity to August 2015. Production from this Formation represents approximately 4% of the total oil production of Argentina and around 3% of the total gas production (Source: Secretariat of Energy of Argentina, Chapter IV).In order to understand the spacial and temporal variations of the Vaca Muerta Formation, it is necessary to return to the framework of sequence stratigraphy using the new data and acquired experience and consolidate all existing interpretations. This possibility of a multicompany regional integration that seems unique in its type so far, was accomplished by the team work of twelveoperating companies with activity in this unconventional objective: Americas Petrogas, Chevron, Exxon, Medanito, Pan American Energy, Petrobras Argentina, Roch, Shell, Tecpetrol, Total Austral, Wintershall and YPF, along with the cooperation and support of the Instituto Argentino del petróleo y del Gas (IAPG), and, at the same time, some other colleagues from the Universidad deBuenos Aires and the Asociación Geológica Argentina (AGA) were also incorporated to the project, and contributed with their knowledge of outcrops of this Formation. LCV Laboratory also contributed with the detailed analysis of rock samples.
