Analyses are presented of the High Energy Gas Fracturing experiments, where a tailored pressure pulse is used to form multiple radial fractures extending from a borehole into the formation. The analyses were performed using a finite element model with a tensile stress crack formation criterion. In-situ stresses and gas pressurization of the cracks (as a fraction of borehole pressure) were included. Results show a good correlation with experimental data. Predictions for upcoming tests are made. Areas for additional work include material model improvements and coupling of the propellant burn/gas flow/structural models.
