Abstract
The authors propose the method to estimate deformation properties of rocks by the data on pressure meter tests in hydrofractured interval, allowing in situ values of Young’s modulus and Poisson’s ratio of rocks. It is shown that integration of pressure meter tests and hydraulic fracturing expands the scope of deformation measurements and improves efficiency of stress assessment in rocks using hydrofracturing method.
