摘要： A method of performing a fracture operation at a wellsite is disclosed for a wellsite positioned about a subterranean formation having a wellbore therethrough and a fracture network therein. The fracture network includes natural fractures. The method involves generating wellsite parameters of the wellsite comprising seismic measurements, generating smooth fracture parameters of a smooth fracture by solving governing equations based on the wellsite parameters, and generating ledged fracture parameters of a ledged fracture by identifying ledge locations and generating ledged fracture parameters of a ledged fracture at the ledge locations by solving the governing equations based on the wellsite parameters for the ledge locations.

摘要： A method of performing a fracture operation at a wellsite is provided. The wellsite has a fracture network therein with natural fractures. The method involves stimulating the wellsite by injecting an injection fluid with proppant into the fracture network, obtaining wellsite data comprising natural fracture parameters of the natural fractures and obtaining a mechanical earth model of the subterranean formation, defining the natural fractures based on the wellsite data by generating one or more realizations of the natural fracture data based on a statistical distribution of natural fracture parameters, meters, generating a statistical distribution of predicted fluid production by generating a hydraulic fracture growth pattern for the fracture network over time based on each defined realization and predicting fluid production from the formation based on the defined realizations, selecting a reference production from the generated statistical distribution, and optimizing production and uncertainty by adjusting the stimulating operations based on the selecting.
