Webinar: A Numerical Exploration of Hydraulic Fracture Interference - 2021 ARMA

Laboratory and large-scale experiments are invaluable tools to study fracture
interference. To support this effort, we use 3D numerical simulations to predict and investigate possible modes of fracture interference and clarify the underlying mechanisms. The benefit of physically based numerical modeling is that it offers the advantages of unrestricted experimentation possibilities and repeatability. The qualitative aspect of the findings may uncover surprising results that demand experimental confirmation and may lead to increased understanding. A short inventory of cases of fracture interference, observed over the past 10 years of using a 3D lattice based numerical code is presented in this talk. The stress shadow effect is one of the main factors influencing fracture interference, and the effect is shown in a simple stress analysis.

This presentation by Dr. Christine Detournay (Principal Engineer, Itasca Consulting Group) is a featured ARMA Hydraulic Fracturing Community (HFC) “Warm-Up” webinar.

ITASCA is a global, employee-owned organization that is grounded in 40+ years of innovations by trailblazing software developers and engineers alike. We provide the world’s most widely used geotechnical software in applications.

The generated fracture width limit is set to 1 inch, meaning the fracture did not propagate until it reaches 1 inch, I think that this assumption is not valid for brittle rocks as our fractures generally do not reach these numbers, please correct me if am wrong
