    摘要： 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.

    摘要： A method can include providing, in a geological domain, a conformal mesh, conformal to geological discontinuities of a geological model, that includes depositional domain coordinates associated with a depositional domain; providing, in the depositional domain, an initial, at least vertically structured, multidimensional grid that includes initial nodes that define grid cells; referencing the conformal mesh to identify a set of grid cells of the initial grid traversed by the geological discontinuities; splitting each of the grid cells in the set to form sub cells, each of the sub cells defined at least in part by one or more new nodes; and assigning geological domain coordinates associated with the geological domain to at least the new nodes to generate a final grid that includes the initial nodes, the new nodes and geological domain coordinates associated with the geological domain. Various other apparatuses, systems, methods, etc., are also disclosed.

    摘要： A method and system for producing look-ahead profiles measurements includes positioning an energy transmitter, such as a transmitting antenna, proximate to a borehole assembly tool. One or more energy receivers, such as receiving antennas, are positioned along a length of the borehole assembly. Next, energy is transmitted to produce look-ahead scans relative to the borehole assembly tool. Look-ahead graph data with an x-axis being a function of a time relative to the position of the borehole assembly tool is generated. The look-ahead graph is produced and displayed on a display device. The look-ahead graph may track estimated formation values based on earth models. The estimated formation values are displayed below a tool position history line that is part of the look-ahead graph. The estimated formation values in the look-ahead graph may be based on inversions of resistivity data from the look-ahead scans.
