How to generate the Final Rock Stress Model (FRSM) at a site or an area

A strategy and a flow sheet for establishing the Final Rock Stress Model (FRSM) is proposed and described, see Figure 1. The development of FRSM consists of four major steps. In the first step one is defining the classes of rock stress and extracting existing data from databases. Together with geological and morphological information and borehole and drillcore data one establish the Best Estimate Stress Model (BESM). In the next step, called Stress Measurement Methods (SSM), new stress data from borehole methods and core-based methods are recorded and evaluated. Thereafter, data from direct and indirect stress measurements are combined in an Integrated Stress Determination (ISD) with or without support from numerical stress modeling. The combination of available information will generate the Final Rock Stress Model at a site or an area. Examples include the European stress map, stress decoupling in the North German Basin, stress perturbation from faults in Sweden of importance for radioactive waste disposal.
