The influence of host rock heterogeneity on stress distribution and brittle deformation (co-organized)
Convener: Aisling Soden  | Co-Convener: Heather Moir 
Brittle fractures are the most prevalent deformation structures in the uppermost part of the earth’s crust and are therefore central to the development of fluid flow models. Accurate characterisation of fault and fracture attributes are key in evaluating potential nuclear waste repositories, carbon storage reservoirs, hydrocarbon reservoirs, geothermal reservoirs and understanding the occurrence of induced seismicity. A primary control on fracture attributes is host rock heterogeneity such as the occurrence of layering, inclusions and lateral and vertical variations in porosity. The resultant contrast in mechanical properties perturbs local stress distributions and influences fracture formation and growth. Understanding the control host rock heterogeneities have on brittle deformation structures is paramount to site characterisation and development of robust flow models.
In this session we invite multidisciplinary, innovative contributions that address the affect of host rock heterogeneity on deformation structure development through field or experimental (numerical and analogue) methods.
