Abstract
A realistic fracture model that adequately describes a fracture-stimulated reservoir is fundamental for subsequent flow and heat transfer analyses of the system. This paper describes a method to create such a model using seismic events recorded during the fracture stimulation process. The method is a Bayesian framework in the form of Markov Chain Monte Carlo (MCMC) simulation that effectively produces a fracture model conditioned by the seismic point cloud. The method is applied to Geodynamics’ Habanero reservoir in the Cooper Basin of South Australia and detailed connectivity analysis between Habanero 1 and 3 is reported. The freeware FracSim3D is used for the analyses.
