Abstract
The present invention relates to a method of determining present-day horizontal stresses in geological formations. The method comprises dividing the received well data in a plurality of contiguous sets of data i, a set of data For each set of data i in the plurality of sets of data, determining, at least parameters Pi, a pressure in subsoil i, bi, a Biot coefficient i, νi, a Poisson's ratio i, σνi, a vertical constraints in subsoil i, Ei, a Young's modulus i, αi, a thermal expansion coefficient, and Ti, and a subsoil temperature i. The method further comprises, i, computing and outputting the horizontal constraints.
