  • Patent number: 10794154
    Abstract: 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.

  • Patent number: 10544667
    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.

  • Patent number: 10422208
    Abstract: A method involves generating a hydraulic fracture growth pattern for a fracture network. 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.

  • Publication number: 20140151035
    Abstract: A method of performing an oilfield operation about a wellbore penetrating a subterranean formation are provided. The method involves performing a fracture operation by generating fractures about the wellbore. The fractures define a hydraulic fracture network (HFN) about the wellbore. The method also involves generating a discrete fracture network (DFN) about the wellbore by extrapolating fracture data from the HFN. The DFN includes fracture branches with intersections therebetween and matrix blocks. The method also involves generating a depth of drainage through the DFN, defining production parameter(s), and performing a production operation to produce fluids from the subterranean formation based on the depth of drainage and the production parameter(s). The production operation may involve generating a flow rate through the DFN, generating a pressure profile of the DFN for an initial time based on the flow rate, and generating a production rate based on the pressure profile.

  • Patent number: 7853440
    Abstract: Method for modeling acidification within a porous medium as a result of the injection of an acid. A dual-medium model is constructed, considering a first sub-medium favorable to dissolution breakthroughs and a second sub-medium not favorable to dissolution breakthroughs. For each one of these sub-media, a metric-scale description of the acid transport, of the sub-medium and acid mass conservation and of the acid transfer from one sub-medium to the other sub-medium is achieved. This dual-medium model is then initialized from experimental calibrations. Finally, acidification of the medium is modelled by means of this dual-medium model.
