Abstract

Summary

This paper describes an integrated workflow to characterize the properties and behavior of an enhanced geothermal system (EGS) in four steps, applied to the Utah FORGE dataset. Static modeling is carried out first, including structure modeling, lithology, and rock properties, as well as the construction of a discrete model of natural fractures with a tectonic-based prediction algorithm, from which permeability is derived. The second step is stimulation design, based on reservoir mechanical properties and natural fracture geometry, which allows for forecasting hydraulic fracture propagation and selecting the most effective stimulation strategy. Dynamic heat and fluid flow simulations then calibrate the permeability of the natural and hydraulic fractures, as well as the initial temperature distribution, and forecast heat production performance over 30 years. Finally, the flow simulations are coupled with a geomechanical model to compute stress changes over time and their impact on well integrity and the stability of faults and fractures.
