Abstract: A system and method is provided for performing stimulation operations at a wellsite having a subterranean formation with a reservoir therein. The method involves acquiring integrated wellsite data (e.g., geomechanical, geological, and/or geophysical properties of the formation, and/or geometrical properties of the mechanical discontinuities in the formation). The method also involves generating a mechanical earth model using the integrated wellsite data, and identifying a crossing behavior between an induced hydraulic fracture and at least one discontinuity in the formation. The method also involves optimizing a stimulation plan to achieve an optimized crossing behavior. The stimulation plan includes at least one of fluid viscosity, rate of injection of the fracturing fluid, and concentration of a fluid loss additive. The optimization may further include adjusting the stimulation plan to achieve the optimized crossing behavior between the induced hydraulic fracture and the discontinuity in the formation.

Abstract: Methods of performing a fracture operation at a wellsite with a fracture network are provided. The methods involve obtaining wellsite data and a mechanical earth model, and generating a hydraulic fracture growth pattern for the fracture network over time. The generating involves extending hydraulic fractures from a wellbore and into the fracture network of a subterranean formation to form a hydraulic fracture network, determining hydraulic fracture parameters after the extending, determining transport parameters for proppant passing through the hydraulic fracture network, and determining fracture dimensions of the hydraulic fractures from the hydraulic fracture parameters, the transport parameters and the mechanical earth model. The methods also involve performing stress shadowing on the hydraulic fractures to determine stress interference between fractures and repeating the generating based on the determined stress interference. The methods may also involve determining crossing behavior.

The generating involves representing hydraulic fractures as a vertically stacked elements, extending the represented hydraulic fractures laterally from the wellbore and into the formation to form a hydraulic fracture network by adding new elements to the vertically stacked elements over time, determining hydraulic fracture parameters of the represented hydraulic fractures, determining transport parameters for the proppant passing through the hydraulic fracture network, deriving an estimated fracture tip velocity from a pressure and a stress profile of the formation; extending a height of the vertically stacked elements and the new elements over time based on the derived velocity to form extended vertically stacked elements.

Abstract: A method of performing a fracture operation is provided at a wellsite. The wellsite is positioned about a subterranean formation having a wellbore therethrough and a complex fracture network therein. The complex fracture network includes natural fractures, and the wellsite stimulated by injection of an injection fluid with proppant into the complex fracture network. The method involves generating wellsite data comprising measurements of microseismic events of the subterranean formation, modeling a hydraulic fracture network and a discrete fracture network of the complex fracture network based on the wellsite data, and performing a seismic moment operation. The method involves determining an actual seismic moment density based on the wellsite data and a predicted seismic moment density based on shear and tensile components of the simulated hydraulic fracture network, and calibrating the discrete fracture network based on a comparison of the predicted moment density and the actual moment density.

Abstract: In one aspect, a method of optimizing a sequenced hydraulic fracturing treatment to be performed on a well includes predicting, based on a well model of the well and a hydraulic fracturing treatment schedule, a seal state of a perforation cluster. The method may further include updating, based on the predicted seal state, a pilling operation of a stage of the hydraulic fracturing treatment schedule. The method may further include modifying the sequenced hydraulic fracturing treatment schedule to be performed based on the updated pilling operation. The well model includes a geomechanical model of the well and a geological formation.
