Abstract
Hydraulic fractures are stable tensile fractures driven by the injection of a viscous fluid into a solid. In widespread use since almost 80 years for the stimulation of hydrocarbon wells, this technology has evolved and nowadays finds applications in different industrial activities. For example, it is used to store surplus renewable electricity in the form of elastic energy, to create chemically reactive barriers in remediation projects for
contaminated soils and to measure the minimum in-situ principal stress in rock formations. While propagating in geomaterials, hydraulic fractures face the presence of heterogeneities at different scales spanning from the sizes of lithological layers to rock bedding planes. In this talk, the mechanical aspects of the interaction with heterogeneities will be addressed. The questions that will be considered are: “when a hydraulic fracture can be stopped by a heterogeneity of fracture energy?”, “for how long two tough layers can contain the hydraulic fracture propagation?” and “how current models of hydraulic fracture propagation compare to experiments?”
Bio
Carlo graduated from University of Padua (Italy) with Civil Engineering degree in 2016 focusing on Structural mechanics. From 2017 to 2018 he was an early-stage researcher for the CISM-Lab (Internationlal Center of Mechanical Sciences). He has been in one year exchange at the Institute of Continuums Mechanics in Hannover (Germany). During this period, he worked on fracture propagation in heterogeneous fully-saturated porous media. Then, he started his PhD in 2018 at the GEL (Geo Energy Laboratory) with Prof. Brice Lecampion. His research focuses on the study of the effect of heterogeneities on the propagation of hydraulic fractures.
