2007). Thus, it is crucial to explore how hydraulic fracturing process will happen in complex geological settings. Geological data and its response to hydraulic fracturing can be obtained from in-door experiments or/and field study. Since the laboratory study undergoes can perform onfrom small-scale rock samples with several cubic centimetres to large ones with one cubic metre or more, it is easy to control the stress conditions and make artificial structures. Especially in large scale experiments, it is possible to build a full size borehole, or to control the development of hydraulic fractures, and the hydraulic fracture geometries can be obtained easier and parametric study can be quite handy (Haimson 1981). Field study is much more complex because the mechanical behaviours and geologic conditions and in-situ stress fields are different (Warpinski 1996). Although the laboratory experiments can be controlled easily and repeated several times but getting the samples from some formation like Montney are difficult and expensive. Many methods can be used to evaluate hydraulic fracturing directly from field
