P271 IN-SITU STRESS STATE FROM INVERSION OF A NEW ELASTO-PLASTIC FRACTURE MODEL Summary 1 The paper presents an improved inversion method to determine the in-situ stress state from borehole fracturing measurements. A new elasto-plastic fracture model is derived based on laboratory measurements. An improvement in modeling of field data is demonstrated. Introduction The most important way to determine the in-situ state in wells is analysis of fracturing data. This paper presents an improved method. It is a common assumption that the borehole fracturing pressure is governed by the Kirsch equation. Furthermore this non-penetrating model is commonly assumed to define the
