The aim of this work is to understand the complex pattern of active stress field orientations revealed by borehole&#13; breakout analysis with respect to the tectonic structures in a wide region of Northern Italy. The area is located in&#13; the central-western part of the Po Plain between the south verging Southern Alps structures and the north verging&#13; buried folds and thrusts of the Monferrato and Emilia arcs. Little information concerning the active stress field is&#13; available because of the low seismicity level and the thick layer of sediments that covers the entire zone. A detailed&#13; borehole breakout analysis has been performed in 36 wells with depths ranging from 2.2 to 7.3 km, whose&#13; data have been supplied by Eni. Breakout analysis determined the minimum and maximum horizontal stress directions&#13; (Shmin and SHmax). The results show a very complex pattern, pointing out that the stress field is not uniform.&#13; In this area the regional stress field seems not «strong» enough, compared to the local one, so most of the&#13; wells detect only the local field. This work contributes to clarify the various Shmin orientations observed in this&#13; area, pointing out at wide scale, a general compression in NNE-SSW direction in this complex region
