N2  - In recent years, the development of unconventional reservoirs has become more relevant in Argentina, so understanding how to maximize the productivity of drilled wells is one of the main objectives. One of the factors that impacts productivity is the efficiency in the development of hydraulic fractures. For this reason, it is convenient to consider the orientation of in situ stresses. This factor is also essential when defining the location of wells because there could be interferences of fractures from different wells, affecting productivity. Furthermore, it can affect the development of the block defining the orientation of horizontal wells. In this way, knowing the direction of the maximum horizontal stress (SHmax) is essential for an effective hydraulic fracture which means that the Stimulated Rock Volume (SRV) is maximized. With this objective, a horizontal stress orientation map was made for the Neuquén basin based on the interpretation of well images, both acoustic and resistive, and microseismic monitoring. In this work, the resulting SHmax orientation map is presented from the analysis of 273 wells recorded in different blocks of the Neuquén basin, covering a significant areal distribution. As a result, a predominantly E-W SHmax orientation is observed, controlled by tectonic forces. Moreover, there were identified and evaluated areas where the SHmax deviates from the regional trend inducing rotations in vector directions
