Patent ID: 10302814

Abstract:
A method for stimulating an earth formation according to a stimulation scenario for extracting hydrocarbons from the earth formation includes: selecting an earth formation stimulation scenario; applying a modified Mohr-Coulomb model that is configured to estimate behavior of a rock formation during the stimulation scenario, the modified Mohr-Coulomb model having a term representing dilatation in an out-of-plane orientation; predicting a fracture and damage network using the modified Mohr-Coulomb model; converting the fracture and damage network into permeability; simulating fluid flow in the earth formation using the permeability to predict hydrocarbon production; computing a value of a metric for hydrocarbon production for the selected stimulation scenario; iterating the selecting, applying, predicting, converting, simulating, and computing until the metric value meets or exceeds a threshold value; and stimulating the earth formation using a stimulation treatment system according to the stimulation scenario having the metric value that meets or exceeds the threshold value.
