Utah FORGE Phase 3 resulted in successful connection of wells 16A and 16B through fluid-driven fracturing. A brief circulation test demonstrated commercial flow rates, with most of the injected fluid recovered at the production wellhead. However, several technical challenges remain - particularly in reservoir stimulation methods and interpretation of monitoring data. This study analyzes and estimates hydraulic fracture growth resulting from the stimulation of Well 16C with forward numerical models based on the thermo-hydro-mechanical software XSite. The numerical model explicitly represents preexisting fractures with a stochastic discrete fracture network (DFN), capturing the interaction between hydraulic and natural fractures. The results of this analysis focus on the extent and spatial distribution of fracture growth originating from Well 16C, providing insight into further developments of the FORGE reservoir.
